1. INTRODUCTION (CONTINUED)
Stoneleigh House fronts onto Tram Road (A260) and appears to be a traditional brick masonry structure, with a steel frame retrofitted to support a first-floor extension (which is essentially a modular unit).
George Stone House appears to be constructed with traditional load bearing brick masonry however the roof frame is to be inspected and may be steel trusses. The building is built up to, and abuts, a historic wall. The historic wall and site retaining wall are to be retained and not damaged during the works.
The site will be accessed from Tram Road.
DDS will engage a scaffold contractor for the design and installation of a protective scaffold system to the front and side (party wall) elevations of Stoneleigh House. The scaffolding will be clad with heavy duty monarflex, protect public areas.
Refurbishment and Demolition Surveys are to be carried out. Asbestos materials have been identified (corrugated asbestos cement roof sheets).
In accordance with The Control of Asbestos Regulations 2012 any Licensed Works asbestos materials will be removed by a specialist Licensed contractor DDS. Environmental Ltd. The Non-Licensed Works asbestos materials will be removed by DDS.
All asbestos materials will be transported by a licensed carrier and disposed of in a licensed landfill site. All necessary transfer / consignment notes will be issued as part of the completion waste file.
The services to the buildings for demolition are live. The arrangements for survey, tracing, isolation and termination of the services are to be made by Development House Ltd.
A temporary water supply will be maintained for damping down dust and a temporary electrical supply for the site welfare.
DDS are 9001, 14001 & 45001 compliant and proud of our respected reputation within the Construction Industry for the successful completion of sensitive demolition contracts.
All demolition works will be carried out in accordance with BS 6187:2011 - Code of Practice for Demolition.
DDS are fully aware that the key to a successful contract will be to fully segregate and protect the General Public, client operatives and adjacent structures from the impact of the demolition works – both visually and physically, from debris, dust, noise & vibration.
The site will be secured with Heras fencing prior to demolition works commencing. Gates will be incorporated into the fencing at the pavement crossover location. A banksman will protect pedestrians and road users whilst vehicles enter or leave the site.
The demolition of the structures will be progressed gradually using a combination of handheld tools (adjacent to the retained historic wall) and 360° excavators. The works will always be governed by safety. The method, routes of access and techniques may change as the condition of the structures unfolds.

Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 9 Stoneleigh House, Folkestone Demolition Method Statement
NOISE & DUST
Noise Strategy
The works will be carried out in accordance with the BS 5228 Code of Practice and more specifically the recommendations set out in the BS 5228:1997 AMD 1 Code of Practice for Noise Control on construction and demolition sites.
Works’ plant and equipment will also comply with the Noise at Work Regulations 1989 protecting on- site personnel.
Demolition techniques, choice of plant and equipment will be utilised to complement the nature of work being undertaken for example, hydraulic pulveriser attachments used to break concrete in-lieu of percussive breaker tools.
Local environs will be considered during the planning phases of the works including the proximity to sensitive receptors i.e. public walkways / highways, adjoining properties, residential dwellings, businesses and other work faces.
Noisy plant and equipment will be sited as far as reasonably practicable from sensitive receptors and will be of the latest design, equipped with noise silencing technology examples of which include:
• Compressors fitted with lined and sealed acoustic covers, kept closed whenever in use. • Pneumatic percussive tools fitted with mufflers or silencers. • Heavy plant in intermittent use being shut down in intervening periods between work activities. • Planned deliveries to avoid congestion within the, or on the approach to the site.
Evidence of maintenance of all engine driven plant and vehicles will be held on site. Vehicle engines, including dumpers and excavators will be switched off when idle or during loading. Attenuation equipment for tools, plant and machinery, where provided will be maintained in good condition and correctly fitted.
Precautions will be taken to minimise noise and the detrimental effects thereof on local community and operatives on site.
Thorough planning of the works will precede identifying any noisy operations and the impacts they may have on key receptors.
Where noisy works are recognised as having a fundamental impact on a receptor the works will be planned in order to minimise the noise generating activity and / or restricted to certain times as not to cause nuisance.
If during the works noise levels are significant, or there is a complaint, the works causing the elevated noise levels will cease and an investigation carried out to determine the causes and remedial measures.
All operatives will be instructed at safety inductions to ensure noise levels are kept to a minimum and that unnecessary shouting, abusive language or other verbal disruptions are forbidden.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 10 Stoneleigh House, Folkestone Demolition Method Statement
6. NOISE & DUST (CONTINUED)
Dust Suppression Strategy
During critical phases of the demolition works airborne dust will be created.
The controlled use of fine water sprays will be employed to assist in the reduction of dust emissions. Water arising from misting operations will be contained so as not to give rise to flooding or create nuisance outside the working area.
Waste materials, including empty containers, paper, waste or debris, will be placed in designated waste disposal skips placed around the site and not allowed to be blown about the site and adjacent area.
All containers will be totally enclosed or covered by nets/tarpaulins to prevent escape of dust or waste materials during loading and transfer from site to authorised waste recycling/disposal centres.
The burning of rubbish or any other material on Site will be strictly prohibited.
If during the works dust levels are significant, or there is a complaint, the works causing the elevated dust levels will cease and an investigation carried out to determine the causes and remedial measures.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 11 Stoneleigh House, Folkestone Demolition Method Statement
SITE BOUNDARY
DDS will erect Heras fencing to secure the boundary at the front of the site.
The existing front boundary wall will be demolished and replaced with Heras fencing. The boundary walls / fencing to the sides and rear will be maintained.
Signs will be erected by DDS on the hoarding warning of the nature of the works to be undertaken and to provide 24-hour contact details.
Gates will be incorporated into the fencing for pedestrian and vehicular access to each site
The gates will be kept closed whenever possible to prevent unauthorised entry to the site during the working shift. At the end of each shift a check will be made to the security of the site.
Heras fencing will be erected to demarcate welfare / compound areas and demolition exclusion zones within each site.
Heras fencing panels will be lifted, carried and positioned by two operatives. The feet will be lifted, carried and positioned by one operative. The fencing panels will be double clipped. Every 5 or 6 panels the fencing will be triangulated to stabilise the fence line.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 12 Stoneleigh House, Folkestone Demolition Method Statement
TRAFFIC MANAGEMENT
2 No. DDS Banksmen will be posted at the site entrance to protect pedestrians or warn approaching traffic whilst marshalling wagons or delivery vehicles on/off the site. There is sufficient space on site to turn vehicles and leave site in a forward gear.
If required, the Banksmen will temporarily extend concertina fencing across the pavement to halt pedestrians.
The Banksmen will then temporarily halt traffic if required, to allow the vehicle to drive into site.
The Banksmen will adopt the same procedure when vehicles leave the site.
If at any time the number of Banksmen is considered inadequate the process will be reviewed and then number of banksmen increased, or the procedures adapted.
All deliveries to and from site, in particular H.G.Vs, will be carefully controlled to ensure minimal disruption to the local environment is caused. Local speed limits will be observed at all times.
Communication will be maintained between Site Supervisor and all drivers entering site to ensure ‘stacking’ of vehicles does not occur on any surrounding roads.
If there is no room on site, the Banksman will turn vehicles away until space is available on site.
Unloading of equipment and materials will be controlled and in accordance with the Manual Handling Operations Regulations 1992.
Flatbed delivery vehicles will have a handrail / edge protection system to be used when loading / unloading.
The Banksmen will liaise with all delivery drivers and ensure records (waste tickets etc) are in place.
All containers will be totally enclosed or covered by nets/tarpaulins to prevent escape of dust or waste materials during transfer from site to authorised waste recycling/disposal centres.
The roadway adjacent to the site will be regularly swept during the course of the working day to maintain cleanliness and to minimise the mess that vehicles leaving the site can cause.
Site and road conditions will be continuously monitored, and adequate facilities will be provided for wheel washing (jet wash) and road cleaning should it be necessary.
No contractor vehicles will park in the roads adjacent to the site. There is sufficient room to provide onsite parking.
DDS will communicate the advantages of using public transport to all site personnel. Details of the local bus and rail networks – identifying key routes to the project will be posted on site notice boards and will be covered in the site induction to promote the use of public transport.

9.3 SOFT STRIP
Fig: Internal View
In accordance with the phasing the structures will be soft stripped ahead of the demolition to remove rubbish, fixtures, fittings and non-load bearing structures.
By soft stripping the buildings the demolition concrete and hardcore will be processed more efficiently - all combustible materials are removed and contamination of the recycled hardcore is minimised.
Vigilance regarding the structural integrity of each building will always be maintained by operatives and Site Manager.
When other known hazardous materials have been removed and any live services terminated and confirmed, the soft stripping of the buildings and subsequent removal of internal debris, can commence.
The soft strip materials will be broken down by hand and transferred outside the buildings.
The operatives will use the correct lifting procedure, share loads where necessary and wear protective gloves to BS EN 388.
Any work at height will be accessed by using mobile towers or podium steps.

INTRODUCTION - SAFE SYTEMS OF WORK
The fundamental principal and format of the DDS Method Statement is designed to be a document which is focused upon ‘Task Specific Methodology and associated Risk’. The aim is to succinctly set out the primary objectives of the methodology and risks ensuring it is easily communicated to the reader. Task specific method statements will frequently refer to the relevant ‘Standard Operating Procedures’ these will explain the combined sub-procedures required to undertake the primary task, simultaneously limiting digression, and focusing principally on the key task.
Method Statements and Risk Assessments will be formulated by the Technical Manager with assistance from the Estimating Team and Contract Managers. Method statements will be issued and authorised (signed on both parts) before being issued to site.
Standard contents of the DDS Demolition method statement may consist of:
1. Scope of works 2. Briefings (inductions) 3. Welfare 4. PPE, Labour & Plant 5. Supervision 6. Site hazards & control measures 7. Demolition Method 8. Standard Operating Procedures 9. Risk assessments and COSHH assessments 10. Environmental considerations
High level risk activities will be controlled by the task-specific method of work but may also have to be carried out under a permit to work system - all permits are issued by the site supervisor and signed off prior to the end of the working day and before workers can leave site.
It is the responsibility of the site supervisor to review the daily activities and determine if the risk has changed, and if the existing methodology has become redundant requiring a revision /addendum of the risk assessment and method statement, and s subsequent re-briefing of the site team.
When any change is made to the RAMS by the supervisor, technical manager or contracts manager, the site team MUST be notified immediately by way of daily task briefing. All operatives must attend the briefing ands sign to acknowledge their understanding and acceptance of the changes.

1. ASBESTOS MANAGEMENT
The dangers of exposure to asbestos. The widespread presence of asbestos and the risk to health through exposure to it makes asbestos dangerous. Asbestos can produce very small fibrous dust particles that can cause asbestosis, lung cancer and mesothelioma, and eventually death.
The Company will: • R&D Survey to all buildings due for demolition with all suspect material to be analysed for their asbestos content • If no analysis is available, it will be assumed to be asbestos • If licensed asbestos is identified, it will be removed by an HSE Licensed contractor
Procedure for Asbestos Removal (Non-Licensed): To ensure compliance with the existing asbestos regulations, all removal works will be conducted by trained and experienced persons only.
The following must be considered and implemented for all non-licensed asbestos removal works:
1. All staff involved are in possession of non-licensed training 2. All staff involved are in possession of face fit certification for their chosen/issued RPE 3. All staff are clean shaven each day they are performing removal tasks 4. The work area has been suitably segregated using physical barriers 5. Asbestos removal & prohibition signage is in place 6. Operatives are using CAT 3 Type 5 coveralls, with hoods over mask straps 7. The work area has adequate dust suppression (killer sprays/jet wash etc.) 8. A personal decontamination zone has been established with 2x buckets of water and sponges, accompanied by a H Type Vac and clear waste bags 9. Suitable arrangements made for storing/disposal of wastes 10. Exposure records are maintained and returned to the office 11. All ACM’s removed are done so in a safe manner without excessive breakage 12. All wastes produced are bagged continuously and not left to build up 13. No unauthorized use of power tools during removal processes
Please Note: For asbestos removal works involving mobile plant and machinery, a designated clean down zone should be established away from the asbestos zone. Drivers must have the above detailed PPE within their cabs in case of a breakdown and must use it if they exit their machine in the work area. Bespoke RAMS will be produced prior to undertaking this type of works.
Emergency Procedures: In the event that licensed materials are discovered, all works are to stop, restrict access to the area and report to the site supervisor, who will liaise with his CM and licensed contractor.
In the event that a waste bag splits and spills asbestos waste and dust, all works to cease, restrict access and area cleaned up prior to any further access

2. ASPERGILLOSIS
Aspergillosis is a condition caused by aspergillus mould. There are several different types of aspergillosis. Most affect the lungs and cause breathing difficulties. Aspergillosis is usually caused by inhaling tiny bits of mould. The mould is found in lots of places, including: • Soil, compost and rotting leaves • Plants, trees and crops • Dust • Damp buildings • Air conditioning systems
You cannot catch aspergillosis from someone else or from animals. Most people who breathe in the mould do not get ill. Aspergillosis is rare in healthy people. You are usually only at risk of aspergillosis if you have: • A lung condition – such as asthma, cystic fibrosis or chronic obstructive pulmonary disease (COPD) • A weakened immune system – for example, if you have had an organ transplant or are having chemotherapy • Had tuberculosis (TB) in the past
The Company will: Check operatives for symptoms of aspergillosis which include: • Shortness of breath • A cough – you may cough up blood or lumps of mucus • Wheezing (a whistling sound when breathing) • A high temperature of 38C or above • Weight loss
Procedure: You cannot always prevent aspergillosis. It's almost impossible to completely avoid aspergillus mould. But there are things you can do to reduce your risk of aspergillosis if you have a lung condition or weakened immune system: • Try to avoid places where aspergillus mould is often found, such as compost heaps and piles of dead leaves • Wear a face mask in dusty places
Please Note: If you already have a lung condition, your existing symptoms may get worse. Non-urgent advice: See a GP if you have: • A cough for more than 3 weeks • A lung condition that is getting worse or harder to control with your usual treatment • A weakened immune system and symptoms of aspergillosis
Emergency Procedures: Get an urgent GP appointment if you cough up blood. Call 111 if you cannot see your GP.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 5 Standard Operating Procedures
3. BIRD DROPPINGS
Ornithosis: An infection causing flu or pneumonia-like symptoms from inhaling dust contaminated with exudates from infected birds. Not common but could be fatal. Extrinsic allergic alveolitis: From sensitisation to proteins in bird droppings. Again, not common but could be serious. Stomach upset/gastro-enteritis: From ingestion of bacteria in bird droppings, especially where hygiene is inadequate.
The company will: • Provide Disposable Coveralls • Provide Gloves • Provide Respiratory Protective Equipment (RPE) FFP3 with coal filtration • Rubber Boots • Provide cleaning equipment
Procedure: Transmission occurs by inhalation of dry dust, so dustless methods are recommended when cleaning up droppings/feathers: • Wetting down of dry deposits may be helpful, but operatives should avoid water jetting, which would create contaminated aerosols • Scraping and scooping up with shovels is acceptable so long as the material is not dry and dusty, in which case it should be dampened down • A safe system of work should include keeping others without suitable respiratory protection away from the area where the removal work is being done • Waste material is to be bagged, sealed and disposed of at an appropriate waste facility. • A high standard of washing facilities should be provided and before smoking, eating or drinking, hands and exposed skin should be thoroughly washed • Smoking eating and drinking should not be allowed in or adjacent to contaminated areas
Care should be taken where work is carried out in or close to buildings such as hospitals where there may be immune-compromised people.
Please Note: If you already have a lung condition, your existing symptoms may get worse. Non-urgent advice: See a GP if you have: • A cough for more than 3 weeks • A lung condition that is getting worse or harder to control with your usual treatment • A weakened immune system and symptoms of aspergillosis
Emergency Procedures: Get an urgent GP appointment if you cough up blood. Call 111 if you cannot see your GP.

4. CABLE AVOIDANCE SCANNING
Before you undertake any digging, a permit to break ground and a permit to dig will be issued by the site supervisor or principal contractor. It will be the Client and / or Principal Contractor’s responsibility to carry out the necessary investigations to ensure that no live services are concealed below the ground prior to breaking ground.
The company will: • Obtain all available services drawings. • Ensure operatives have adequate CAT training. • Provide calibrated CAT & Genny. • Physically demarcate / plot the location of known / identified cables. • Produce a site plan detailing cable location. • Ensure suitable protective measures are in place or provision of certified disconnection.
Procedure: The following will be carried out for the safety of any person that could be affected by our works. • Cable avoidance training will be provided. • Utility service drawings to be read to aid systematic approach. • The area to be worked on will be clearly marked sequentially in a ‘grid’ system. • Cable avoidance tool and generator will be hired. • The trained operator will sweep the area systematically to ensure the entire area has been covered. • Permit to break ground & permit to dig will be issued only once all services have been identified. • If needed, the generator will be clipped onto any exposed services, to aid the CAT scanner. • If digging is required, insulated tools will be used. • No mechanical digging within 500mm of services.
Please note: Procedures for dealing with a service strike below the ground will be posted for reference in all welfare facilities. Telephone numbers for utility services will be held on site within the Construction Phase Plan, all supervisors will be familiar with this.
Emergency Procedures: All strikes • Do not attempt repairs. • Inform utility supplier/service owner as soon as possible. • Report all damage, even if leaks or loss of power are not evident. • Inform service users. • Inform owners of adjacent services if there is a risk of gas or water ingress or contamination. • Keep members of the public away and post warning signs.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 7 Standard Operating Procedures
Electric cable strikes • Avoid all contact. • Do not try to disentangle cables from excavator buckets. • Do not attempt to leave the excavator involved unless assured that the cable is no longer live. • Evacuate workers and others to a safe distance. • Keep vehicles and members of the public away from the area. • Contact service owner and emergency services as appropriate. • Co-operate with and assist cable owner and emergency services
Gas strikes • Call national emergency number 0800 111999*. • Evacuate workers and others to a safe distance. • Warn local residents and businesses. • No smoking or naked flames. • Keep vehicles and members of the public away from the area. • Warn service users if a service connection has been disturbed as this may result in a leak within the building. • Co-operate with and assist gas supply company, police, and fire authority
First aid • Do not move a casualty unless they are in direct danger. • Take care not to touch exposed cables or tools and equipment which could be live. • Any electrical burn or electric shock injury must be given medical attention however minor it may seem. • Call an ambulance if necessary.

5. CONCRETE CRUSHER
The company will: • Ensure the site crusher operates under a crushing licence/permit with the Council. • Ensure all working parts are in good working order. • Ensure a sufficient water supply is provided for dust suppression. • Ensure the operator has the appropriate training and experience.
Procedure: • When operating the concrete crushing plant, the manufacturer’s instructions will be followed. • The concrete crushing plant will be sited on firm, level ground in an agreed location away from the site boundary. A clear access to and from the crushing plant will be maintained at all times. • The concrete and brickwork demolition arisings will be stockpiled adjacent to the crusher. All steel reinforcement / members will be separated from the concrete using a 360° excavator fitted with a silent hydraulic concrete cruncher which pulverises, using powerful crushing jaws, concrete slabs, columns and beams. The concrete lumps will be reduced to a maximum 600x300x150mm in size. • Crushed concrete stockpiles will be located in agreed locations and will not exceed 3 metres in height. • The crushing process begins when the concrete material is fed into the hopper of the concrete crushing plant using a 360° excavator fitted with bucket attachment. The hopper has a feeder control to regulate the quantity of material that is fed directly into the crusher. It is important that the conveyors are not overloaded. • The crusher has a throttle to control the speed at which the material is being crushed. • Once the material is crushed, it then falls onto the screen feed conveyor. • Any reinforcement is removed with a magnet. • In the event of a blockage the crusher will be isolated, and the keys removed. • The concrete materials will be crushed to a Type 1/6F2 material in accordance with the Specification. • The materials will be tested to confirm classification.
Please Note: No plant, machinery or vehicles will be used on the site unless fitted with hazard lights and reversing alarms in accordance with the manufacturer's recommendations and specifications. The noise generated by the concrete crushing process is comparable to road noise at the site boundary.
Emergency Procedures: In the event of an emergency, stop the machine, remove keys, and contact your supervisor or emergency services if required.

6. CONFINED SPACES
A confined space is a workplace whereby an employee can become consumed by a free flowing solid, liquid or gas. Confined spaces may also have limited access and egress.
The Company will: Adopt alternate methods of working to avoid or limit working in confined spaces as much as practicable.
Procedure: • A site risk assessment, in writing, will have been carried out by the competent person and due note to be taken before any confined space works are initiated. • You will carry out atmospheric monitoring throughout the works • You will assess the of suitability for operatives entering a confined space (risk assessment) • You will assess the equipment to be used • You will put in place a tried and tested rescue plan
A Method Statement and a Permit to Work in confined spaces will be issued by the competent person, before any works commences and induction training will be given. The hazard and risk assessment will clearly define the control measures to be adopted in the confined space working area.
From time to time, it may be necessary to use an air fed respirator system to operate within a confined space. If this situation should occur, you will be given the necessary training on the use of the equipment, emergency procedures and all other features.
Please Note: This legal requirement will be initiated in writing, only by DDS Demolition Limited Senior Management. All persons entering a confined space will be provided with adequate training, and refresher training throughout the contract, to ensure competence at all times. At no time will any staff be permitted to enter a confined space without the necessary training and safe systems of work.
Emergency Procedures:
• Use a risk assessment to determine the likelihood of risks in order to know which rescue equipment is required. • Equipment must be properly maintained. • Ensure rescuers are fully trained in how to use the equipment. • ‘Self-rescue’ equipment, such as breathing apparatus, may be appropriate in situations where there will be time to react to an anticipated emergency situation.

9. DEMOLITION PROCEDURES & TECHNIQUES
Due to the versatile nature of the demolition industry, variety of construction types, advanced technology and plant, there are many different ways to demolish a structure. To list them all and detail the methodology for each type, would replicate documents we already have in place, such as the BS:6187, NFDC guidance documents, our H&S policy arrangements and RAMS.
To give a brief overview of the methods used at DDS, please read below. For detailed methodologies, please refer to your issued site RAMS.
The company will: (Dependant on type and location of structure) • Top down – smaller demolition plant placed on the roof and progressively working downwards • High reach – specialist demolition plant capable of demolishing the structure from roof down, whilst positioned at ground level • Hand demolition – used rarely for sensitive areas such as heavily populated areas or during cut and carve works • Controlled collapse – structure is assessed by engineers, pre-weakened and collapsed within a safe collapse zone, typically using demolition plant to pull or push the weakened structure • Explosive – engineers will survey and determine the extent of explosives and locations. Charges will be installed, set and set off at an agreed time, with vast exclusion zones in place
Procedure: • Produce RAMS / Demolition Plan. • Ensure all services have been identified and isolated. • Ensure all asbestos or hazardous substances are removed. • Ensure appropriate segregation, signage and protection of the public is installed. • Ensure provision of suitable welfare and first aid equipment. • Ensure all staff have the appropriate training for specific tasks. • Ensure all appropriate local authority / HSE notices have been procured. • Ensure there are suitable measures in place managing for control of dust, noise and vibration.
Please note: There are many other factors to consider when planning and undertaking a demolition project, each project is different and must be considered, risk assessed and planned for accordingly.
Emergency Procedures: Every demolition project must have an emergency procedures plan clearly displayed and communicated during induction. Suitable First Aiders and First Aid equipment is to be provided, emergency numbers and local emergency services details must be clearly displayed.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 13 Standard Operating Procedures
10. DIGGING AND BREAKING GROUND
The company will: When digging or disturbing the earth we will take care to avoid damaging underground services.
Underground electrical cables can be particularly hazardous because they often look like pipes and it is impossible to tell if they are live just by looking at them. Damage to underground electrical cables can cause fatal or severe injury and the law says care must be taken precautions to avoid danger.
Procedure: Excavation work should be effectively managed to control risks, including: • Planning the work • Using cable plans • Cable locating devices • Safe digging practices • Planning the work
Most service cables belong to a Distribution Network Operator (DNO). However, some cables belong to other organisations such as the highways authority.
Checks of nearby for equipment owned by the organisations listed above will be made, and if we suspect there are underground cables, request for plans will be made to confirm their location.
When excavating near cables, operatives experienced in underground cable detection techniques will locate them using suitable equipment.
Checks will need to be made to ensure underground cables dead for the work to proceed safely. Be aware that electricity companies are required to give five days' notice to customers whose supply is to be disconnected.
Careful planning and risk assessments are essential before the work starts. Risk assessments will consider how the work is to be carried out, ensuring local circumstances are considered.
Using cable plans
Plans or other suitable information about all buried services in the area will be obtained and reviewed before any excavation work starts.
If the excavation work is an emergency, and plans and other information cannot be found, the work should be carried out as though there are live buried services in the area.
Symbols on electricity cable plans may vary between utilities and advice should be sought from the issuing office. High-voltage cables may be shown on separate plans from low voltage cables.
Plans give only an indication of the location, and number of underground services at a particular site. It is essential that a competent person traces cables using suitable locating devices.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 14 Standard Operating Procedures
Cable locating devices
Before work begins, underground cables must be located, identified, and clearly marked.
The position of the cable in or near the proposed work area should be pinpointed as accurately as possible by means of a locating device, using plans, and other information as a guide to the possible location of services and to help interpret the signal.
Locators will be used frequently and repeatedly during the course of the work.
Operatives who use a locator will have received thorough training in its use and limitations. Locating devices will always be used in accordance with the manufacturer's instructions, regularly checked and maintained in good working order.
Safe digging practices
Excavation work will be carried out carefully and follow recognised safe digging practices.
Once a locating device has been used to determine cable positions and routes, excavation may take place, with trial holes dug using suitable hand tools as necessary to confirm this.
We will excavate alongside the service rather than directly above it. Final exposure of the service by horizontal digging is recommended, as the force applied to hand tools can be controlled more effectively.
Insulated tools will be used when hand digging near electric cables.
Please Note: No works should be undertaken unless a permit to dig / break ground is issued.
Emergency Procedures: In the event of an emergency, stop the plant, place in a safe position, and contact your supervisor, first aider or emergency services if required. If a cable is struck ensure the area is segregated and the utility company are contacted immediately.

11. DROP ZONES
To aid and minimize manual handling needed to be conducted on our sites, the use of drop zones can be assessed & considered.
Drop zones will limit the distance an operative has to travel whilst carrying/moving a load, typically during soft stripping.
Drop zones can be established by typically removing a window from the external wall of a building, providing a 1000mm high upstand is left to create a barrier, preventing leading edges and falls. If removing the window or other item to create the opening for the drop zone, leaves a leading edge with the potential for a person to fall, a suitable fixed barrier must be installed upon its removal. If the opening is going to create a temporary leading-edge issue, a man anchor and harness system must be employed during the opening up and installation of fixed barrier process.
The Company will: Provide all the necessary equipment to install suitable and safe ‘drop zones’.
Procedure: Drop zones can only be used: • from the 5th floor or below • In good weather conditions (not in excessive wind) • If there is a designated zone below the opening which is segregated using Heras fencing and debris netting • If suitable signage is in place • If there is a safe distance between the drop zone and neighbouring sites/premises. The higher the drop, the greater the distance required at ground level. • The drop zone must include a buffer zone, allowing for potential for materials to travel. • Refer to NFDC guidance and BS: 6187:2011 for further guidance.
Please note: Other considerations are the communication method between those dropping wastes and those operating plant below, clearing the waste. Use of 2-way radios is our common choice with one operative controlling the drops at high level, stopping any drops until the machine has cleared the arisings below.
Multiple Levels If we are operating on multiple levels, a clear safe system of works must be adopted so that those working on floors below do not attempt to drop wastes whilst the zone above is in use. Best practice would be to establish further zones at different elevations or simply prohibit dropping from certain levels.
Emergency Procedures: In the event of an emergency, stop the machine, remove keys, and contact your supervisor or emergency services if required.

12. DUST, NOISE AND VIBRATION
The company will: DDS will use all reasonably practicable means to protect the adjacent buildings from the detrimental effects of dust, noise and vibration.
Dust noise and vibration monitoring may be carried out in accordance with the specification.
Dust, noise and vibration monitoring positions will be established around the site.
Readings will be taken to establish background levels using handheld or static meters. Regular readings will be taken during the works.
If dust, noise and vibration levels are elevated, trigger levels breached or there is a complaint, the works causing the elevated noise levels will cease and an investigation carried out to determine the causes and remedial measures.
Dust will always be controlled and kept to a minimum by damping down with water at source in accordance with Environmental Protection Act 1990.
Depending on the working environment and demolition activity to be conducted the method of suppression to be used will be determined.
Procedure: • Mains hose operated by DDS operative • Airless sprayers • Mobile jet washers with fine mist spray • Motofog, used for small and medium sized products and can cover a reasonably large area • Dust Boss, come in various sizes with oscillating heads and used on medium to large scale projects • Built in suppression systems on demolition excavators • Tractor & bowser
Although controlling dusts is our primary concern, consideration must be given to those within close proximity to our sites. Selecting the correct method is crucial as we do not want to control the dust excessively and have significant water runoff and create a nuisance with overspray to local residents, business owners and the public.
Water run off must be considered to ensure dusty water is not unlawfully discharged into surface water drains. This can be achieved by bunding site drains prior to structural demolition.
Although this task sheet is designed to give guidance on controlling dusts at source, if this cannot be significantly controlled, the use of face fitted RPE with FFP3 filters may still be required for site staff. The use of RPE should always be a last resort if collective measures can be adopted.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 17 Standard Operating Procedures
Please Note: 1. No demolition is authorised to start without adequate dust control in place 2. We have a legal duty to protect our own staff and those outside of our sites 3. Think outside the box, it’s not just dust in the air that is a problem. Water run-off containing dusts will damage rivers and streams 4. Site staff must be adequately protected 5. We may be prosecuted by local authorities, HSE and environment agency for poor control of dusts. Which could lead to loss of work, increased insurances, loss of clients & compensation claims
Waste materials will be placed in designated skips and not allowed to be blown about the site and adjacent area.
All containers will be totally enclosed or covered by nets/tarpaulins to prevent escape of dust or waste materials during transfer from site to authorised waste recycling/disposal centres.
Works will be carried out in accordance with the BS5228 Code of Practice which contains information and procedures for the control of noise on construction sites.
Only those items of plant producing minimum noise levels will be used and noisy activities will be examined with the aim of introducing control measures, and where possible, locate plant and machinery as far as is reasonably practicable from sensitive receptors.
Evidence of plant maintenance for all engine driven plant and vehicles will be provided. Vehicles engines, including dumpers will be switched off when the vehicle is idle or whilst being loaded. Attenuation equipment for tools, plant and machinery, where provided will be maintained in good condition and correctly fitted.
All operatives will be instructed at safety induction to ensure that noise levels are kept to a minimum and that unnecessary shouting, abusive language or other verbal disruptions are forbidden.
Emergency Procedures: If dust, noise, and vibration begin to cause an unacceptable level of environmental issues, work is to stop immediately, and methodology is to be revised accordingly.

13. FIRE EVACUATION
The company will: Ensure when a fire starts, consideration will be given to how everyone will have to vacate the premises, this will be done by way of risk assessment and the other fire precautions put in place. A fire plan will be produced detailing the ‘fire warden’ ‘fire points’ ‘Escape routes’ and ‘assembly points’
Procedure: The evacuation plan in case of a fire will be simply through the means of gathering everyone’s attention via a warning signal when a fire is discovered and having everyone make their way to a designated safe area that is away from the building. This is the simultaneous evacuation plan and it will be initiated by either the sound of a fire alarm or fire warning system such as manually operated ‘Klaxon’ horn.
Actions are taken upon hearing the fire alarm
Once operatives hear the alarm telling them of a fire happening within the building, they must learn the proper action to take. Operatives should calmly proceed to the pre-determined positions that will place them in the nearest safe zones. lifts and elevators must never be used in the event of a fire as there is the chance that an electrical failure could stop them from moving. The plan will also state that all personnel, with the exclusion of the fire brigade, must not re-enter the premises once they are out of the danger.
Calling the fire brigade
Once a fire that cannot be handled has been determined, the operatives must quickly call the Fire Brigade. This should be done person who has discovered the fire if possible.
Identification of key escape routes
If there is a fire, operatives must know where to go to get to safety. While there are some who already know their way around the building, there may be those who are still unfamiliar with the layout of and not know where the fire exits are. The fire evacuation plan must contain a diagram which shows employees where all of the emergency fire exits are located. This way, all of the employees will be able to head to safety the moment they realize that a fire is happening in the workplace.
Places of assembly and roll call
Use appropriate signs whenever possible so that employees will have no doubt about where they need to go in the event of a fire.
How to use the fire equipment provided
A nominated fire marshal, if available, or any trained competent person should, where possible, assess and/or control the fire only if they have all the necessary equipment that allows them to do so. However, firefighting comes only second to the safety of those within the building. Nobody should be put at risk and all employees must prioritize their safety over anything else.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 19 Standard Operating Procedures
Required training
The emergency evacuation plan should be the subject of employee induction training so that everyone on site is familiar with its contents. It is also recommended that fire drills are undertaken, and operatives have understood where it is they should go and what to do in the event of a fire. It is especially important that this type of training is carried out and that its results are recorded.
Please note: Only attempt to tackle a fire if it is safe to do so.
Emergency Procedures: Contact and notify all of the external emergency services within your area about your fire emergency evacuation plan. There should be a senior person nominated to meet the fire and rescue service when they arrive so that he or she will be able to give all of the necessary information that they will need to prevent the fire from spreading or help those who were not able to make it out safely from the building. The person that you have nominated must have sound knowledge of the layout of the building and must also have some form of contact with all of the appointed leaders of each pre-determined assembly point to provide whatever information is acquired regarding the fire.

14. HOT WORKS
The company will: Take all reasonable steps will be taken to avoid the outbreak of fire, particularly during 'hot' work involving the use of naked flame or intense heat and will prevent the accumulation of rubbish on the site.
Procedure: • A 'Hot-Works' permit to work system will be enforced when any works of this nature are undertaken, and fire extinguishers will be prominent. • Hot works will cease 1 hour before the end of a working shift and the area thoroughly checked by the Fire watchman prior to leaving site. • Combustible floors, walls, ceilings protected by wetting down and covering with damp sand or covered or screened by sheets of non-combustible material – whichever is suitable. • The accumulation of rubbish on the site will be prevented by regular clearance. • Oxygen and Propane bottles will be stored outside, segregated in a lockable cage in an upright position and protected from impact – the position will be agreed on site and marked up on the site plan. Fire extinguishers will be positioned adjacent to the storage area. • The correct colour coded hoses will be used. All hoses, cutting equipment, arresters and regulators will be visually checked prior to connection to gas bottles. • All hose and terminal connections to cutting equipment and regulators / arresters will be checked for leaks.
Please note: Where steel has been painted with lead paint there is a risk of the fumes causing respiratory disease and systemic poisoning. In accordance with Control of Lead at Work Regulations 2002 the following control measures will be implemented: • Good natural ventilation • Forced ventilation • Veraflo TR300 – Powered Air Respirator BS EN 12941 • Blood lead levels monitored
In addition to the regular PPE, during hot works operatives will wear an Airstream helmet, fire retardant overalls, gauntlets and goggles. Consideration will be given to welding apron and boots where flame cutting is undertaken.
Emergency Procedures: Before starting any hot works, a fire plan must be in place, this is to include location of fire points and firefighting equipment, fire alarm, fire exits and routes clearly demarcated, details of emergency assembly points and emergency services contact number and address.

15. LEPTOSPIROSIS
Leptospirosis is spread in the urine of infected animals – most commonly rats, mice, cows, pigs and dogs. You can catch it if:
• Soil or freshwater (such as from a river, canal or lake) containing infected urine gets in your mouth, eyes or a cut • You touch an infected animal's blood or flesh
The company will: Ensure facilities are provided for good personal hygiene, this must be maintained since there is a risk of contracting Weil’s disease if rats are present.
Procedure: Do
• Wash your hands with soap and water after handling animals or animal products • Clean any wounds as soon as possible • Cover any cuts and grazes with waterproof plasters • Wear protective clothing if you are at risk through your job • Shower as soon as possible if you have been in potentially infected water
Do not
• Do not touch dead animals with your bare hands • Do not drink water from places like rivers, canals or lakes that has not been boiled
Please note: You might have a serious infection that needs to be treated quickly. Your GP may prescribe antibiotic tablets to treat the infection. You should make a full recovery in a few days or weeks.
Emergency Procedures: See a GP if you might have been exposed to infected pee and you have:
• A remarkably high temperature, or feel hot and shivery • A headache • Feeling and being sick • Aching muscles and joints • Red eyes • Loss of appetite
Ask for an urgent appointment if you have:
• Yellow skin and eyes (jaundice) • Swollen ankles, feet, or hands • Chest pain • Shortness of breath • Coughing up blood

16. MANUAL HANDLING
Manual handling is defined as Lifting, Pushing, Pulling, Twisting & Putting Down.
The Company will: Ensure that all DDS staff are protected from personal injury from manual handling, you must ensure that wherever possible you look to move any load using mechanical means.
Our manual handling operations will typically be during non-licensed asbestos removal, soft stripping, movement of small mobile equipment and picking activities.
Procedure: The site supervisor must, in accordance with the issued method statement, ensure that you soft strip in a methodical manner from top down and use mechanical aids where possible to move wastes to the designated drop zone/loading area/storage area. This may include the use of wheelbarrows, wheelie bins etc. Every effort will be made to ensure that physical manual handling is kept to a minimum.
The following will be considered when assessing manual handling tasks: Task What is to be carried out Individual/s Who is going to carry out the work, are they capable? Load Characteristics of the load, does it move, does it have handles, can it be broken down. Environment Where is the load being taken, does the route need clearing etc.
Please note: To ensure that all staff are adequately protected from manual handling risks, you must ensure that: 1. You rotate manual handling tasks, so that operatives can be rested from repeat activities 2. Dual lifting is conducted by those of similar abilities 3. Persons involved with manual handling can easily communicate with each other 4. All persons are familiar with safe manual handling controls 5. A written risk assessment is compiled and understood by all staff
Emergency Procedures: In the event of an emergency, stop work and contact your supervisor or emergency services if required.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 23 Standard Operating Procedures
17. MECHANICAL LIFTING
Lifting using excavators and telehandlers will be required from time to time and must be planned and controlled adequately to prevent incidents.
The company will: For basic lifts such as moving welfare cabins or machine attachments, the lift will need to be risk assessed and documented, using the basic lift check sheet form. These are detailed as basic lifts, due to the height in which they need to be lifted (enough to clear the floor) and because they have standard lifting practices.
The chains, shackles, lifting points and lifting equipment will be inspected prior to the lift and will be in possession of inspection certification for the chains and plant. Other considerations will be to the ground upon which the lifting is taking place (is it suitable and free from below ground services) and above ground services such as power lines.
Procedure: Lifting operations will only be carried out by suitably trained and certificated individuals. Lifting appliances and lifting equipment will be thoroughly examined by an external competent person at the following frequencies: • Lifting equipment and appliances used for lifting people will be thoroughly examined at intervals not exceeding 6 months • Lifting accessories such as chains and shackles examined at intervals not exceeding 6 months • All other lifting appliances will be thoroughly examined at intervals not exceeding 12 months
Lifting equipment are to be operated as per the manufacturer’s guidance at all times and as per the training received by each operator. Failure to operate machinery safely will result in disciplinary action against the user. If at any point, any employee is unsure of what is asked of them they are to seek advice from their immediate supervisor or SHEQ department.
Please note: For more complex lifts, DDS will hire in a ‘Contract Lift’ with suitably competent lift supervisors, slingers, crane supervisor who will issue lifting plans and use their own certified equipment.
Emergency Procedures: In the event of an emergency, stop work and contact your supervisor or emergency services if required.

Procedure: Where necessary, access to carry out the works at height may be provided from a MEWP or man riding platform supported by an all-terrain telescopic handler.
The platform has anchor points on which to attach safety harnesses with fall restraint lanyard.
The ground conditions will be noted to ensure the surface is level, free from debris and stable.
The conditions overhead will be noted to ensure operatives on the platform are not at risk from loose debris, protrusions, live cables etc.
Please note: MEWP’s must never be operated by an untrained operative.
Emergency Procedures: A working at height rescue plan should be in place prior to starting work and all operatives made aware during induction or daily task briefings. In the event of an emergency, stop work and contact your supervisor or emergency services if required.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 25 Standard Operating Procedures
19. MOBILE TOWERS
In some instances, work at height may be accessed using mobile aluminium towers.
The company will: Ensure equipment is appropriate for the task, in good working order.
Operatives are provided with the appropriate level of training to safely erect access towers.
Procedure: Mobile towers will be erected by PASMA certificated persons in accordance with the manufacturer’s instructions.
Mobile towers and ladders will be tagged for daily inspection.
A Mobile Tower register will be kept and signed off. The tower will be erected on a level stable surface and the wheels will be locked to prevent movement during use.
The tower will not be repositioned whilst persons are on the working platform.
The purpose-built access ladder will be used to climb to the working platform – operatives will not climb up the outside of the tower. Equipment will be passed up to the operatives on the working platform.
Outriggers will be used, if necessary, to increase the base-to-height ratio.
Please note: Only trained operatives are permitted to erect the tower Ensure the tower is always erected on firm level ground. Once in the working deck of the tower, operatives must NOT climb or reach out of the tower.
Emergency Procedures: A working at height rescue plan should be in place prior to starting work and operatives made aware during induction or daily task briefings. In the event of an emergency, stop work and contact your supervisor or emergency services if required.

20. PEDESTRIAN AND TRAFFIC MANAGEMENT
By Law, pedestrians or vehicles must be able to use a traffic route without causing danger to the health or safety of people working near it. Roadways and footpaths should be separate wherever possible by a physical barrier and clear signage. By Law, traffic routes must also keep vehicle routes far enough away from doors or gates that pedestrians use, or from pedestrian routes that lead on to them, so the safety of pedestrians is not threatened.
The company will: Carry out a Risk Assessment and the following points taken into account: • If vehicles and pedestrians have to use the same route. • The best way to mark out and sign vehicle and separate pedestrian areas. • Mark out and sign crossing points for drivers and pedestrians • Other hazards which present a health and safety risk i.e. materials that may fall from a vehicle; excessive or sudden noise; fumes etc. • Ensure that the following are made aware of the route and layout: 1) Staff who work on site - by training 2) New staff - by Induction 3) All visitors to site are escorted by a member of the contractor’s staff
Procedure: Pedestrians Wherever it is reasonable to do so, separate routes or pavements will be provided to keep pedestrians away from vehicles. Where possible pedestrian routes will represent the paths people would naturally follow (known as ‘desire lines’) to encourage people to stay on them.
Pedestrians will be kept away from areas where vehicles are working unless they need to be there.
Barriers and Markings
The following procedures will be followed to keep vehicles away from pedestrian areas: • Protective barriers • Clear marking to set apart vehicle and pedestrian routes • Raised kerbs to mark vehicle and pedestrian areas • Provide suitable barriers or guard rails where needed at entrances and exits to buildings and at the corners of buildings to prevent pedestrians inadvertently walking straight on to a road • Traffic signs must be distinctive, legible and illuminated when dark
Please note: Refer to HSG 144 Book “The Safe Use of Vehicles on Construction Sites”.
Emergency Procedures: In the event of an emergency, stop work and contact your supervisor or emergency services if required. Refer to the ‘Traffic Management Plan’ for emergency vehicle routes.

21. PERMIT TO WORK
The objective of a permit to work system is to maintain close monitoring when potentially hazardous work is being carried out and the following points relating to the permit-to-work procedure should be considered:
The Company will: Provide specialised training required for the task being carried out. The task would usually have been classified as high risk by the risk assessment. The task may be complex - for example: • Electrical Works • Work in confined spaces • Excavation works • Welding and/or hot works • Mechanical maintenance works
Procedure: Permits to work provide a safety control system against accidental injury to personnel, plant and products when known hazardous work is undertaken and a document detailing the work to be done and the precautions to be taken before commencement of work will be issued and will: • Identify the work to be undertaken • Identify who will undertake the work • State the time period for which it is valid • Supersede all other instructions until it is cancelled • Specify the control measures to be put into place before work commences • Identify known hazards that remain a risk to the permit holder • Identify any emergency precautions and procedures which need to be put into place • Identify any first aid facilities which may be necessary • Identify any special welfare facilities which may be necessary • Identify any necessary personal protective equipment • Ensure that no other work than that specified is undertaken • Define the limits of the work and the working area
Please note: Circumstances, locations and work tasks will be identified, and safe working procedures will be implemented and incorporated within the health and safety plan. The permit will consist of four parts, Issue, receipt, clearance and cancellation. All four parts must be signed and carried out before the permit can be cancelled.
Emergency Procedures: In the event of an emergency, stop work and contact your supervisor or emergency services if required. Refer to the Task Specific Rescue/ Safety plan for relevant emergency procedures.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 28 Standard Operating Procedures

Procedure: • Operatives are to be issued DDSD standard ‘5-point’ PPE equipment which includes: Hard Hat, Hi Visibility Vest, Glasses, Gloves and Steel capped boots. • Operatives are to use the PPE appropriately and at all times when working on an active demolition site. • Operatives are responsible for taking care of the equipment and keeping it in good order. • Operatives to report any defects they might compromise safety and request replacement equipment when required.
Please Note: PPE is always a ‘last line of defence’ and must not be relied upon for a safe working environment, safety is always governed by risk assessment.
Emergency Procedures: In the event of an emergency, stop work and contact your supervisor or emergency services if required. Refer to the Task Specific Rescue/ Safety plan for relevant emergency procedures.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 29 Standard Operating Procedures
23. PLANT AND EQUIPMENT
The company will: Ensure that only those over 18, fully trained or supervised during training and authorised by the company will be permitted to operate the machinery. This will be monitored by competent site supervisors/managers. Machines are to be operated as per the manufacturer’s guidance at all times, and as per the training received by each operator. Failure to operate machinery safely may result in damage to the plant, uncontrolled collapse or overturning of the plant.
Procedure: Use of plant and equipment for demolition operations will be in accordance with methods set out by BS6187:2011 demolition code of practice.
All heavy plant and equipment is only to be operated by appropriately trained and experienced operatives who have permission to do so. If you do not have the training you do not use the plant, no exceptions.
All plant and equipment will be maintained in accordance with our planned preventative maintenance program. Inspections will be carried out by the operator prior to work each day and these inspections will be recorded and held on site.
There will be a system installed to ensure that no plant or machinery can be started up on site by unauthorised persons, as all keys will be stored safely within a locked office/cabinet overnight. This system will be under the direct control of the named demolition Site Supervisor/Manager. This system will be followed on all DDS Demolition Limited sites.
All plant must be operated within controlled zones and banksmen must be utilised to assist in safely moving plant around each site.
Buffer Zones
To ensure the safety of all staff working within demolition zones, they will install and abide by the 5- metre rule. There must be a 5-metre buffer zone between all moving plant and ground operatives. That is 5 metres from the end of the arm of an excavator, 5 metres from any elevation of a waste container and so on.
Passing Moving Plant
Only when a machine operative has acknowledged the presence of a ground operative and given appropriate acknowledgement preferably using radio contact, will any ground operative be permitted to pass moving plant. The plant operator must cease all movements until the worker has safely passed the machine.
Prohibited Areas
At no point is any ground operative permitted to work on the blind side of the machine, unless they are at a distance greater that 5 metres of the arm on full stretch.
No ground operative is permitted to work under the arm of the machine or its attachment. For picking of wastes, the machine must be stationary, arm lowered to ground, and selector grab closed.

24. HANDHELD PNEUMATIC BREAKERS (HAVS)
Part of being a capable demolition contractor is being able to deliver a multitude of demolition projects, from industrial, commercial, domestic, and retail using a variety of techniques from traditional mechanical demolition, top down, explosive and when the needs arise, by hand.
Large scale demolition projects by hand are rare, however, we do from time to time get involved with ‘Cut & Carve’ projects which will involve an element of hand demolition, using basic tools and occasionally powered breakers.
The company will: • Provide access to modern equipment which is appropriately tested and in good working order. • Ensure all operatives have adequate training in the use of vibrating tools. • Mange and limit exposure to occupational health issues such as vibration and noise.
Procedure:
• Consider changing to other equipment or tools, which can do the same job with less exposure to vibration. The important thing is to look for equipment or tools that produce less vibration or that can do the job faster. The power-to-weight ratio should be as high as possible. • Purchase and use tools with optimal ergonomic design. This includes good grip comfort, optimal angle of the main handle, and a short distance between the support handle and the front of the tool if used in a horizontal orientation. • If possible, increase productivity of the present equipment to reduce exposure time. • Check the air installation to ensure proper pressure and flow. • Check that you are using the most effective tool for the job task performed. • Train employees / operators to avoid unnecessary exposure to vibration. • Use job rotation to decrease exposure time. • Change the design of the product to reduce the need for tasks involving exposure to vibration or change process completely to get rid of the vibrating task.
Please note: It is important to estimate the exposure duration for each tool was determined by observation and measurement of a sample period of typical work. A stopwatch was used to determine the average duration or the “trigger time” required to perform each work task when the employee / operator was using the tool being evaluated. In addition, the production rates were obtained from the department supervisor to determine the maximum number of repetitions required in a typical 8-hour shift.
Emergency Procedures: Early signs to look out for include changes to any of your fingers: • Sensitivity: Sensitivity includes developing new pain or struggling to feel anything at all. • Strength If you are struggling to pick things up and hold things generally for more than usual, this can become permanent beyond the early stages of vibration white finger. • Colour: Look out for white fingertips, especially when it is cold.
In the event of an emergency, stop work and contact your supervisor or emergency services if required. Refer to the Task Specific Rescue/ Safety plan for relevant emergency procedures.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 32 Standard Operating Procedures
25. RISK ASSESSMENTS
The company will: Ensure that Risk Assessments will be undertaken by the appointed named competent person and the conditions and hazards of each site appraised. Risk assessment will be undertaken on all aspects of the company’s operations and the basic formulations for the site health & safety plan as per the CDM Regulations 2015.
Procedures: The risk assessments will identify: 1. The task 2. Hazards 3. Who is at harm and how? 4. Control measures 5. Residual risk
The site will be assessed using an initial risk assessment document and using a hazard checklist, which will outline the safety hazards according to each specific site.
Since all projects vary in size and complexity each site will have its own unique task specific method statement and will incorporate a specific risk assessment relative to the particular activity.
The method statement and risk assessment will be communicated by the site supervisor/manager to his team prior to starting work.
Please note: Risk assessments will be reviewed periodically by the management and safety teams then amended where necessary to reflect the task specific works being carried out on site. All reviews will be recorded within the necessary amendment section of the method statement.
Emergency Procedures: In the event of an emergency, stop work and contact your supervisor to discuss any unidentified or new hazards or risk. In an emergency, contact the emergency services if required. Refer to the Task Specific Rescue/ Safety plan for relevant emergency procedures.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 33 Standard Operating Procedures
26. SAFETY HARNESS
The company will: • Ensure all users will be trained in the safe use of harnesses. • Equipment provided meets the required standards and is suitable for requirements.
Procedure: All manufacturers’ instructions will be checked prior to use.
All DDS harnesses are to be inspected in-house by our own trained inspectors and have 6-month certification issued by the stores. Only harnesses issued with a cert will be used.
The user must inspect the condition of the harness prior to use and if required ask a ‘buddy’ to assist with the correct fitting of the equipment.
The anchorage point which the harness is being connected to will be secured and capable of taking not only an Operative’s weight but also the inertia generated by a fall.
Anchorage points will be above the Operative wherever possible and never below foot level.
All karabiners will be checked to ensure they are fully tightened.
Where there is a risk of a fall, full body harnesses will be used complete with an energy absorber or dissipater, such as a lanyard and it will be ensured there is adequate clearance below.
Please note: Other means of undertaking the tasks at height must always be explored, a harness is always the ‘last line of defence’ and should not be solely relied upon.
Emergency Procedures: In the event of an emergency, stop work and contact your supervisor, and if required contact the emergency services. Refer to the Task Specific Rescue/ Safety plan for relevant emergency procedures.
Ensure all operatives using a harness are aware of ‘suspension trauma’ risks. If the person is strapped into a harness or tied to an upright object, they will eventually suffer the central ischaemic response. • Feeling faint or light-headed • Breathlessness • Profuse sweating • Very pale • Feeling very hot, quickly • Nausea • Increased heart rate or significantly decreased heart rate • Exceptionally low blood pressure • Dizziness • Grey out or loss of vision
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 34 Standard Operating Procedures
27. SERVICES
One of the main risks during strip out and demolition is penetrating live services. It is essential that all precautions be taken to prevent any such occurrences.
The company will: Ensure that arrangements for the termination of the gas supply will be carried out by the Client or DDS prior to works commencing on site. Certificates confirming termination, or confirmation in writing, are to be provided.
Procedure: A temporary water supply will be maintained for damping down dust / welfare and a temporary electrical supply for the site welfare /task lighting / hoarding lights.
Any live services will be clearly marked.
All physical cuts to the cables and service connections will be inspected to confirm the accuracy of the isolations and proceed with caution since several rogue connections may be encountered.
Checks will be made to lights, switches and sockets using a Fluke® pen to confirm all services have been isolated.
Operatives will be instructed to stop works immediately if they are unsure about the status of any cable etc.
A marked-up drawing showing the position of any capped or terminated services will be produced on completion of the contract for inclusion in the Health & Safety File.
Please note: The risk of contact with live services can obviously be fatal; it is imperative that services are treated with extreme care, and that they are not handled by anyone other than a trained professional, and where possible, services are to be disconnected, demarcated or identified with signage and disconnection certificate issued.
Emergency Procedures: In the event of an emergency, stop work and contact your supervisor to discuss any unidentified or new hazards or risk. In an emergency, contact the emergency services if required. Refer to the Task Specific Rescue/ Safety plan for relevant emergency procedures.
Electrocution: Caution Do not touch the injured person if he or she is still in contact with the electrical current. • Call 999 or your local emergency number if the source of the burn is a high-voltage wire or lightning. Do not get near high-voltage wires until the power is turned off. Overhead power lines usually are not insulated. Stay at least 20 feet (about 6 meters) away — farther if wires are jumping and sparking. • Do not move a person with an electrical injury unless he or she is in immediate danger.

28. SHARPS
The company will: Undertake a survey of the building with particular attention to when there has been unauthorised entry to the buildings, or the buildings have been vandalised, a thorough visual inspection will be carried out for syringes and other drug paraphernalia to the buildings for strip out / demolition and surrounding area.
Procedure: All operatives involved will have received a toolbox talk / induction regarding ‘Sharps’ training.
In addition to regular PPE the operatives will be issued with anti-puncture gloves.
When needles are discovered they will be picked up using handheld tongs and placed in a ‘Sharps Tin’.
The ‘Sharps Tin’ will be taken to a licensed facility for disposal.
Please note: Reports of discarded needles and syringes are treated as urgent. When needles and syringes are left in public places this can often lead to fear and anxiety about the risk of transmission of infection. In reality the risk to health is extremely low because any injures are usually superficial and the blood in the syringe may no longer be infectious.
Emergency procedure: If you pierce or puncture your skin with a used needle, follow this first aid advice immediately: • Encourage the wound to bleed, ideally by holding it under running water • Wash the wound using running water and plenty of soap (do not use bleach) • Do not scrub the wound while you are washing it • Do not suck the wound • Dry the wound and cover it with a waterproof plaster or dressing. • You should also seek urgent medical advice to assess your need for PEP or other treatment to reduce the risk of getting an infection.

29. SITE BOUNDARY
The company will: Take appropriate measures to manage access across defined boundaries; and steps to exclude unauthorised people. While the numbers of children being killed or injured on construction sites has reduced, there is no room for complacency. Each year, two or three children die after gaining access to sites, and many more are injured. Other members of the public are seriously injured by: • Materials or tools falling outside the site boundary. • Falling into trenches; or • Being struck by moving plant and vehicles.
The pre-construction information should include: • Project boundaries. • Adjacent land use. • Access; and • Measures to exclude unauthorised people.
Procedure: Site Boundaries You need to define boundaries physically, where necessary, by suitable fencing. The type of fencing should reflect the nature of the site and its surroundings. • Plan what form the perimeter will take. • Provide the fencing; and • Maintain the fencing.
Considerations: • What is the nature and type of the work? • How heavily populated is the area is? • Who will need to visit the site during the work? • Will the site attract children? • What are the site characteristics (e.g. existing site boundaries, location, proximity to other buildings)? Typically, in populated areas, this will mean a two-metre high small mesh fence or hoarding around the site.
Authorisation The principal contractor must take reasonable steps to prevent unauthorised people accessing the site: • People may be authorised to access the whole site or be restricted to certain areas. • You must explain relevant site rules to authorised people and undertake any necessary site induction. • You may need to supervise or accompany some authorised visitors while they are on site or visiting specific areas.
Hazards causing risk to the public Many hazards have the potential to injure members of the public and visitors. Consider if they exist on your project and how you will manage them. Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 37 Standard Operating Procedures
Falling objects
You must make sure objects cannot fall outside the site boundary. On scaffolds you can achieve this using toe-boards, brick guards and netting. You may also need fans and/or covered walkways.
Delivery and other site vehicles
Make sure pedestrians cannot be struck by vehicles entering or leaving the site. Obstructing the pavement during deliveries may force pedestrians into the road, where they can be struck by other vehicles.
Scaffolding and other access equipment
Prevent people outside the boundary being struck while they are erecting, dismantling, and using scaffolding and other access equipment.
Please note: Plywood Hoarding • 2.4m high solid plywood hoardings will be erected, fixed to timber posts concreted into the ground. • At each timber post location, the ground will be surveyed (CAT scan) to determine the location of live services. Holes will be excavated using hand tools. • The posts will be inserted into the holes, lined and levelled. Hand mixed concrete will be used to cast the base for the posts. • When the post bases have cured timber runners will be fixed to the posts and the plywood attached to the runners. Skirting will be fixed top and bottom. • New gates will be installed in the hoarding. The site gates will be kept closed when not in use to prevent unauthorised access to the site.
Heras Fencing • Heras fencing panels will be lifted, carried, and positioned by two operatives. The feet will be lifted, carried, and positioned by one operative. • The fencing panels will be double clipped together. Every 5 or 6 panels the fencing will be triangulated to stabilise the fence line. • Demolition exclusion zones within the site boundary will be demarcated with Heras fencing.
At the end of each shift a check will be made to the security of the site.
Signs will be erected by DDS warning of the nature of the works to be undertaken and a signboard displayed with the following information:
• Title of Project • Name of Employer • Considerate Contractor Scheme (if applicable) • DDS Name and Logo • 24hr telephone number

30. SITE INDUCTION, DAILY BRIEFING, TOOLBOX TALKS
The Company will: Acknowledge its responsibility to make available to all employees, either directly or via ‘representatives of employee safety’, information relating to their health and safety at work.
Procedure: Prior to commencing on site all DDS site operatives and subcontractors who will be involved with the project will receive a Project Specific Induction.
The induction process will be to ensure that the operatives are aware of the method statement with the associated Risk and Coshh assessments of their task, location of asbestos / hazardous materials, proximity of adjacent buildings, emergency procedures, location of any live services, environmental issues and 'no-go' areas i.e.. Drop Zones etc.
On complex projects operatives will be given daily briefings to provide updates to the site status (services, asbestos, demolition zones, fire escapes etc).
Toolbox talks are an effective way of communicating health and safety information to employees on a regular basis (weekly).
Toolbox talks will be given to operatives by the Site Supervisor.
The Toolbox Talk topic, attendees and date will be recorded.
Consultation will be maintained with employees on all projects especially when site inductions, task briefings and toolbox talks are given.
Employees will be actively encouraged to participate and raise any queries they may have relating to health and safety, or any suggestions they may have on improvements to health and Safety.
In particular, consultation will be given to: • The introduction of any measure at the workplace which may substantially affect the Health and Safety of those employees • The arrangements for appointing or nominating persons in accordance with The Workplace (Health, Safety & Welfare) Regulations 1992. • Any Health and Safety information required to be provided under the relevant statutory provisions • The planning and organisation of any Health and Safety training • The Health and Safety consequences of the introduction of new technology
Please Note: DDS will arrange and hold periodic company meetings involving operatives, supervisors, and managers to discuss the findings of recent monitoring, performances, and other relevant safety information. These meeting may be split into their status category so that the meetings can be controlled and productive.

31. TEMPORARY WORKS - INSTALLING & MAINTAINING
Temporary Works in the form of temporary supports or structures are often required to ensure the safety and stability of structures during excavation and demolition. Temporary works will also extend to other designed installations such as hoarding, Heras fencing, excavation supports, temporary electrical supplies and more.
The correct design and execution of temporary works is an essential element of risk prevention and mitigation in construction. BS 5975:2008 provides recommendations and guidance on the procedural controls to be applied to all aspects of temporary works in the construction industry and on the design, specification, construction, use and dismantling of falsework.
The company will: In accordance with the CDM Regulations 2015 temporary works will be designed and installed by competent persons in a safe and timely manner. The skills, knowledge and experience of the designer will depend upon the extent and complexity of the temporary works install. Temporary supports or structures used to support permanent structures will only be erected or dismantled under the direct supervision of a competent person as required by the CDM Regulations 2015.
Procedure: DDS will demonstrate that they have in place effective arrangements for controlling risks arising from the use of temporary works. These are captured in a ‘temporary works procedure’ which will contain most or all of the following elements:
• Appointment of a Temporary Works Co-ordinator (TWC). • Preparation of an adequate design brief. • Completion and maintenance of a temporary works register. • Production of a temporary works design (including a design risk assessment and a designer’s method statement where appropriate). • Independent checking of the temporary works design. • Issue of a design/design check certificate, if appropriate. • Pre-erection inspection of the temporary works materials and components.
Control and supervision of the erection, safe use, maintenance and dismantling of the temporary works i.e., procedures to:
• Check that the temporary works have been erected in accordance with the design and issue a formal "permit to load" where necessary. • Confirm when the permanent works have attained adequate strength to allow dismantling of the temporary works and issue a formal "permit to dismantle" where necessary. • The procedure should include measures to ensure that the design function, the role of TWC, and Temporary Works Supervisor(s) where appropriate, are carried out by competent individuals.
Please note: Temporary Works Co-ordinator
The role of Temporary Works Co-ordinator is to control, monitor and supervise implementation of commonly encountered temporary works and raise the risk awareness.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 40 Standard Operating Procedures
British Standard 5975 sets out one way of managing temporary works (TW) that has been found to work well on medium and large projects and uses the job title Temporary Works Co-ordinator (TWC). There is no legal requirement to use this job title or the BS recommended process, but BS5975 provides an industry consensus view on what is considered to be good practice. The legal requirement is that the party in control must ensure that work is allocated and carried out in a manner that does not create unacceptable risk of harm to workers or members of the public.
Temporary Work Supervisor
As part of your demolition supervisor training, the supervision of temporary works has been covered. You will be required to conduct weekly inspections of all temporary works and record your findings on the temporary works register. Any issues with the installed TWs, will be reported immediately to the TWC for the project.
Training
Training will be provided to enable the person/persons appointed as Temporary Work Co-ordinator or Temporary Works Supervisor before commencement, or these appointments may be made with an external organisation whose competence has been checked.
The minimum standard for persons to fulfil these roles will be the CITB Site Safety Plus Temporary Works Co- Ordinator 2-day Training Course. Certified TWC’s for the company are Mr Dylan Lovelock and Mr Eric Rosay.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 41 Standard Operating Procedures
32. WELFARE FACILITIES
The Construction (Design & Management) Regulations (CDM 2015) are the main set of regulations for managing the health, safety, and welfare of construction projects. CDM applies to all building and construction work and includes new build, demolition, refurbishment, extensions, conversions, repair, and maintenance.
A principal contractor is appointed by the client to plan, manage, monitor, and coordinate health and safety during the construction phase of a project when there is more than one contractor involved.
The principal contractor’s duty is to:
• plan, manage, monitor, and coordinate health and safety in the construction phase of a project • liaise with the client and principal designer • prepare the construction phase plan • organise cooperation between contractors and coordinate their work.
They must ensure that:
• suitable site inductions are provided • reasonable steps are taken to prevent unauthorised access • workers are consulted and engaged in health and safety matters • welfare facilities are provided.
The company will: (when assuming Principal Contractor role) DDS will equip all sites with adequate welfare facilities, and these will include but not limited to: • Canteen with warm running water and adequate heating • Toilet facilities - both male and female (separate if practicable) • Shower facilities (if full body washing is required due to work practices) • Drinking water • Seating with back support • Provision of equipment to prepare a hot meal (kettle and microwave) • Site office (this may be a self-contained welfare van on smaller contracts) • Hand washing facilities
Please Note: It will be the responsibility of the site supervisor, assisted by site personnel to ensure that site welfare facilities are regularly inspected and remain in a clean, hygienic state always.

33. WORKING AT HEIGHTS
Work at height comes in a variety of forms, each with differing ranges of risk severity. All work at height tasks must be assessed following the work at height hierarchy of control, which is detailed below.
The forms of work at height that we will undertake during demolition are: 1. Hop ups – low levels works such as ceiling removals 2. Podium steps – Low level works but of long duration 3. Mobile towers – low to high level works any duration. Must be inspected by PASMA certified individual before use 4. MEWPs (boom & scissor) operated by IPAF certified individuals and full harness in boom lifts 5. Fixed scaffold – erected by external specialists, inspected weekly by the scaffold contractor, and must not be altered by DDS staff 6. All staff must receive suitable training to work at height. This may be in the form of in-house training or external by accredited training providers
The company will: Consider: 1. Ground conditions 2. Obstructions above head height 3. How will you rescue someone at height in the event of an emergency? 4. You MUST always look to use measures that protect everyone, before resorting to PPE use 5. If we are installing barriers at a leading edge, it must be a fixed barrier that cannot move 6. If we are working near a leading edge, ‘man anchor’ systems should be considered
Please note: Work at heights will be carefully assessed, planned, and supervised throughout our work activities.
Emergency Procedures: In the event of an emergency, stop work and contact your supervisor and implement the ‘work at height rescue plan’. Additionally, if required, contact the emergency services on 999.
Ref No. TBC Revision 0 Controlled Document: DDS/Stoneleigh House/Method Statement doc/22.03.21/Demolition 43 Standard Operating Procedures
34. WORKING IN NOISY ATMOSPHERES
The company will: Undertake formal noise assessments will be made if it is likely that any employee will be exposed to: • a noise level of 80dB(A) or above • a peak sound pressure 135dB or above
Procedures: To ensure your safety whilst on site, the following measures will be utilised: • ensure that noise assessments are carried by a competent person • keep records of such assessments until they are reviewed • reduce the risk of damage to hearing from exposure to noise to the lowest practicable level by using well maintained equipment and rotation of employees, reducing time exposed • provide suitable and sufficient ear protectors where exposure is 80 dB(A) and above • designate mandatory hearing protection zones when 85dB is reached • enforce the wearing of ear protectors where exposure is 85dB(A) and above or above the peak sound pressure of 137dB • ensure ear protection equipment is maintained in an efficient state of use • Ensure levels do not exceed 87 dB(A) or a peak sound pressure 140 dB • Use sound barriers around noisy plant to protect others • Ensure all staff are adequately trained in the correct selection and use of hearing protection
To ensure that you understand what hearing protection to obtain you must follow the following rules: • Establish the manufacturers output in dB (each tool will be different) • Each type of hearing protection will have a designated SNR value • If the selected hearing protection has a SNR of 23dB and your tool produces 100dB, your exposure would be 77dB, below the action level • Formula, Tool Output dB (100) – Hearing Protection SNR dB (23) = Exposure of 77dB
Please note: Typical examples of work carried out on demolition sites that can produce significant noise: • Use of reciprocating saws • Use of hydraulic breakers • Working near mechanical plant • Hot cutting • Floor scabbling • Use of Brokks • Generators
Emergency Procedures: Report hearing injury to your supervisor and seek hearing evaluation by a licensed audiologist or other qualified professional, especially if there is concern about potential hearing loss.

Current guidance Social Distancing Workers should maintain a distance of two metres, or one metre with risk mitigation where two metres is not viable. The local COVID alert levels do not restrict construction activities; however, any additional local authority restrictions must be complied with. National guidance on social distancing in England, Scotland, Wales and Northern Ireland should be adhered to off-site Going to Work Workers should be working from home if they can. Those who cannot work from home, which includes workers in construction, manufacturing, logistics and distribution, should go to work. Workplaces that are open should be Covid-19 secure. Face Coverings In accordance with The Use of Face Coverings in Construction, where workers on site are not required to wear Respiratory Protective Equipment (RPE) and their workplace (which may include welfare and changing facilities, site offices or site meeting rooms) meets all of the criteria below, their employer should make face coverings available and they should be worn in: • An enclosed space. • Where social distancing isn’t always possible; and • Where they come into contact with others they do not normally meet. • In line with Government guidance on premises providing hospitality, face coverings must be worn in canteens except when seated at a table to eat or drink.

Version 6b
A. Introduction These Site Operating Procedures (SOP) are based on Government guidance on Working safely during Coronavirus (Covid-19) - Construction and other outdoor work in England; other restrictions and advice may apply in Scotland, Wales and Northern Ireland, as well as in areas subject to a localised lockdown. The objective is to introduce consistent measures on construction sites of all types and sizes and employers and individuals should make every effort to comply. Where workers enter people’s homes, they should follow the Government guidance on Working in Other People’s Homes. The HSE is the relevant enforcing authority for occupational health and safety legislation and guidance to control public health risks in the construction sector. If a site is not complying with the latest Government advice on Coronavirus (Covid-19), it may be subject to enforcement action. Construction sites need to ensure they are protecting their workforce and minimising the risk of spread of Coronavirus (Covid-19) infection. This includes considering how personnel travel to and from site. Government guidance for employers in England states “where the social distancing guidelines cannot be followed in full, in relation to a particular activity, and the activity cannot be redesigned, businesses should consider whether that activity needs to continue for the business to operate, and, if so, take all the mitigating actions possible to reduce the risk of transmission between staff”. The health and safety requirements of any construction activity must not be compromised at this time. If an activity cannot be undertaken safely, it should not take place. Organisations must have in place effective arrangements for monitoring and reviewing their compliance with Government and industry guidance. The workforce should be reminded during inductions and daily briefings of the specific social distancing and coronavirus (Covid-19) control measures necessary to protect them, their colleagues, families and the UK population.
B. When to Go to Work It is important to understand the following guidelines by which workers should or should not travel to work as outlined below.
Social distancing Workers in the construction industry should follow the guidance, relevant to their Tier. Where they cannot work from home, they must follow guidance on Meeting With Others Safely and Safer Travel while travelling to and from work and while at work. Where social distancing cannot be maintained whilst carrying out work on sites, then a Permit to Work in Close Proximity will be completed. Shielding has been paused for those deemed to be clinically extremely vulnerable. If reintroduced in an area by the local authority, workers will receive a new formal shielding notification and advised not to go to work.
MSF55 Page 2 of 8
Version 6b
Self-isolation Anyone who: • Has a high temperature, a new continuous cough, or a loss of, or change in, their normal sense of taste or smell; • Is within 10 days of receiving a positive Coronavirus (Covid-19) test result; • Is within 10 days of the day when the first member of their household or support bubble showed symptoms of Coronavirus (Covid-19) or received a positive test result;
• Has returned from a country that is not on the travel corridors list and is required to quarantine for 14 days; or • Has been contacted by the NHS Test & Trace Service; must follow the guidance on self-isolation and should not come to sitego to work.
If someone falls ill If a worker develops a high temperature, a new continuous cough, or a loss of, or change in, their normal sense of taste or smell while at work, they should: • Ensure their manager or supervisor is informed • Return home immediately • Avoid touching anything • Cough or sneeze into a tissue and put it in a bin, or if they do not have tissues, cough and sneeze into the crook of their elbow. They should get a Coronavirus (Covid-19) test. They must follow Stay at home: guidance for households with possible or confirmed coronavirus (COVID-19) infection and not return to site until they have received a negative test result or, in the event of a positive test result, until they have completed their period of self-isolation and are no longer unwell. Sites that are informed of more than one confirmed case within 14 days will need to contact their local Public Health England protection team. Further information can be found in the ‘What to do if a worker has Covid-19 or has to self-isolate’ flowchart.
C. Travel to Work Using Private Vehicles: Wherever possible workers should try not to share a vehicle with those outside their household or support bubble. If workers have no option but to share transport, they should try to:
• Share with the same individuals and with the minimum number of people (up to a maximum of 6) at any one time
• Keep the windows open
• Travel side by side or behind other people, rather than facing them, where seating arrangements allow
• Maximise the distance between people
• Wear a face covering
MSF55 Page 3 of 8
Version 6b
• The vehicle should be cleaned between journeys, especially touch points, using gloves and standard cleaning products. Due to the new strain of COVID and the higher rate of transmission, staff / contractors should not use DDS vehicles for carrying family members or friends. Using Public Transport: Where public transport is the only option for workers, they:
• Should try to avoid travelling during peak times (05:45 ‐ 8:15 and 16:00 ‐ 17:30); and
• Must wear a face covering. Sites should consider:
• Changing and staggering site hours to reduce congestion on public transport
• Parking arrangements for additional vehicles and bicycles
• Providing facilities such as lockers and showers
• Providing hand cleaning facilities at entrances and exits. This should be soap and water wherever possible or hand sanitiser if soap and water are not available
• How someone taken ill would get home.
D. Driving at Work When travelling at work or between site locations, workers should travel alone. If workers have no option but to share a vehicle, then they should follow the Government guidance on Working Safely during Coronavirus (Covid- 19) - Vehicles, which provides information for people who work in or from vehicles, including couriers, mobile workers, lorry drivers, on-site transit and work vehicles, field forces and similar.
E. Site Access and Egress Points • Stop all non-essential visitors
• Consider introducing staggered start and finish times to reduce congestion and contact at all times
• Plan and manage site access and egress points to enable and control social distancing – you may need to change the number of access points, either increase to reduce congestion or decrease to enable monitoring, including in the case of emergencies
• Introduce one-way systems
• Allow plenty of space between people waiting to enter site
• Use signage:
o such as floor markings, to ensure current social distancing requirements are maintained between people when queuing
o reminding workers not to attend if they have symptoms of Coronavirus (Covid-19) and to follow guidelines
• Require all workers to wash their hands for 20 seconds using soap and water, or hand sanitizer when entering and leaving the site
• Regularly clean common contact surfaces in reception, office, access control and delivery areas e.g. entry systems, scanners, turnstiles, screens, telephone handsets and desks, particularly during peak flow times
MSF55 Page 4 of 8
Version 6b
• Reduce the number of people in attendance at site inductions and consider holding them outdoors wherever possible
• Where loading and offloading arrangements on site will allow it, delivery drivers should remain in their vehicles. Where drivers are required to exit their vehicle, they should wash or sanitise their hands before handling any materials
• Drivers must be provided with access to suitable toilet and hand washing facilities and made aware of the social distancing measures in place
• Consider arrangements for monitoring compliance.
F. Hand Washing • Allow regular breaks to wash hands
• Provide additional hand washing and/or sanitising facilities (e.g. pop ups) to the usual welfare facilities, particularly on a large spread out site or where there are significant numbers of personnel on site, including plant operators
• Ensure adequate supplies of soap and fresh water are readily available and kept topped up at all times
• Provide hand sanitiser (minimum 60% alcohol based) where hand washing facilities are unavailable
• Regularly clean the hand washing facilities
• Provide suitable and sufficient rubbish bins for hand towels with regular removal and disposal.
G. Toilet Facilities • Restrict the number of people using toilet facilities at any one time (e.g. use a welfare attendant) and use signage, such as floor markings, to maintain current social distancing requirements.
• Wash or sanitise hands before and after using the facilities
• Enhance the cleaning regimes for toilet facilities, particularly door handles, locks and the toilet flush
• Portable toilets should be cleaned and emptied more frequently
H. Canteens and Rest Areas A canteen is a place that serves food and an NHS QR code must be displayed and face coverings worn, except when seated at a table to eat or drink. Government guidance on Keeping workers and customers safe during Covid-19 in restaurants should be followed and this Food Standards Agency Checklist may be helpful. Rest areas where no food is served but which have facilities to prepare and eat food and a means of boiling water are not required to display an NHS QR code.
• Consider increasing the number or size of facilities available on site if possible
• The capacity should be clearly identified at the entry to each facility, and where necessary attendants provided to supervise compliance with social distancing measures
• Break times should be staggered to reduce congestion and contact at all times
• Drinking water should be provided with enhanced cleaning measures of the tap mechanism introduced
• Frequently clean surfaces that are touched regularly, using standard cleaning products e.g. kettles, refrigerators, microwaves
MSF55 Page 5 of 8
Version 6b
• Hand cleaning facilities or hand sanitiser should be available at the entrance to any room where people eat and should be used by workers when entering and leaving the area
• Seating and tables should be reconfigured to reduce face to face interactions
• All rubbish should be put straight in the bin and not left for someone else to clear up
• Tables and chairs should be cleaned between each use
• Crockery, eating utensils, cups etc. should be disposable or washed and dried between use
• Payments should be taken by contactless card wherever possible
• Canteen staff should wash their hands often with soap and water for at least 20 seconds before and after handling food
• Canteen staff and workers may use the same rest areas if they apply the same social distancing measures
• Consider arrangements for monitoring compliance.
I. Changing Facilities, Showers and Drying Rooms • Consider increasing the number or size of facilities available on site if possible
• Based on the size of each facility, determine how many people can use it at any one time to maintain current social distancing requirements.
• Restrict the number of people using these facilities at any one time e.g. use a welfare attendant
• Introduce staggered start and finish times to reduce congestion and contact at all times
• Introduce enhanced cleaning of all facilities throughout the day and at the end of each day
• Provide suitable and sufficient rubbish bins in these areas with regular removal and disposal.
J. Work Planning to Avoid Close Working Sites and work need to be planned and organised to avoid crowding and minimise the risk of spread of infection by following Government guidance and the advice within these Site Operating Procedures. Hierarchy of Controls If you are not able to work whilst maintaining current social distancing requirements, you should consider whether the activity should continue and, if so, risk assess it using the hierarchy of controls below and against any sector- specific guidance. The results of risk assessments should be shared with the workforce and this poster displayed in the workplace.
MSF55 Page 6 of 8
Version 6b
Eliminate • Workers who are unwell with symptoms of Coronavirus (Covid-19) should not travel to or attend the workplace • Rearrange tasks to enable them to be done by one person, or in a way that maintains current social distancing requirements. • Avoid skin to skin contact and face to face working • Stairs should be used in preference to lifts or hoists and consider one ways systems • Consider alternative or additional mechanical aids to reduce worker interface Site Meetings • Only absolutely necessary meeting participants should attend • Attendees should maintain current social distancing requirements • Rooms should be well ventilated / windows opened to allow fresh air circulation • Hold meetings in open areas where possible Reduce Risk mitigation, where current social distancing requirements cannot be maintained, could include the following: • Minimise the frequency and time workers are working together where current social distancing requirements cannot be maintained • Minimise the number of workers involved in tasks where current social distancing requirements cannot be maintained • Workers should work side by side, or facing away from each other, rather than face to face • Lower the worker capacity of lifts and hoists to reduce congestion and contact at all times • Regularly clean common touchpoints, doors, buttons, handles, vehicle cabs, tools, equipment etc. • Increase ventilation in enclosed spaces • Workers should wash their hands before and after using any equipment Isolate Keep groups of workers: • Together in teams e.g. do not change workers within teams • As small as possible • Away from other workers where possible
Control • Consider introducing an enhanced authorisation process • Provide additional supervision to monitor and manage compliance
PPE • Coronavirus (COVID-19) needs to be managed through social distancing, hygiene and the hierarchy of control and not through the use of PPE • Workplaces should not encourage the precautionary use of extra PPE to protect against Coronavirus (COVID-19).
Behaviours The measures necessary to minimise the risk of spread of infection rely on everyone in the industry taking responsibility for their actions and behaviours. Encourage an open and collaborative approach between workers and employers on site where any issues can be openly discussed and addressed.
MSF55 Page 7 of 8
Version 6b
K. First Aid and Emergency Service Response The primary responsibility is to preserve life and first aid should be administered if required and until the emergency services attend.
• When planning site activities, the provision of adequate first aid resources must be agreed between the relevant parties on site
• Emergency plans including contact details should be kept up to date
• Consideration must also be given to potential delays in emergency services response, due to the current pressure on resources
• Consider preventing or rescheduling high-risk work or providing additional competent first aid or trauma resources.
L. Cleaning Enhanced cleaning procedures should be in place across the site, particularly in communal areas and at touch points including:
• Taps and washing facilities
• Toilet flush and seats
• Door handles and push plates
• Hand rails on staircases and corridors
• Lift and hoist controls
• Machinery and equipment controls
• All areas used for eating must be thoroughly cleaned at the end of each break and shift, including chairs, door handles, vending machines and payment devices.
• Telephone equipment
• Key boards, photocopiers and other office equipment
• Rubbish collection and storage points should be increased and emptied regularly throughout and at the end of each day.

3. The Use of Face Coverings in Construction during Coronavirus (COVID-19)
The Construction Leadership Council (CLC) has published this statement on the use of face coverings on construction sites in response to coronavirus to help provide a consistent approach across the industry. It is based on Government guidance in England and other restrictions and advice may apply in Scotland, Wales and Northern Ireland. Definitions Face coverings are made from fabric or cloth and cover the mouth and nose to protect others, not the user, from infection. They are not PPE as they do not protect people from work-related hazards and are not made to a recognised standard. Surgical face masks are designed and manufactured to be used in medical settings to limit the spread of infection and they are resistant to droplets of fluids and splashes. Whilst they are made to a recognised standard, they are not considered to be PPE. Visors, which are usually worn to protect the face and eyes, are classed as PPE and protect the user, not others, against droplets carrying infection. Respirators, which are used extensively in construction activities, are classed as PPE and protect people from work-related hazards that cannot be eliminated or reduced in any other way. They should be specific to the hazard identified and provided free of charge by employers. Current Position The use of face coverings in response to coronavirus is mandatory for members of the public in an increasing number of specified places, most of which meet all of the following criteria: • enclosed public spaces • where social distancing isn’t always possible • where people come into contact with others they do not normally meet. The use of face coverings and/or PPE is not required in response to coronavirus whilst carrying out construction activities, and the Government guidance on Working safely during coronavirus (COVID-19) – Construction and other outdoor work states that: Workplaces should not encourage the precautionary use of extra PPE to protect against COVID-19 outside clinical settings or when responding to a suspected or confirmed case of COVID-19. CLC Position Where workers on site are not required to wear Respiratory Protective Equipment (RPE) and their workplace (which may include welfare and changing facilities, site offices or site meeting rooms) meets all of the criteria below, their employer should make face coverings available and they should be worn in: • an enclosed space; • where social distancing isn’t always possible; and • where they come into contact with others they do not normally meet. In line with Government guidance on premises providing hospitality, face coverings must be worn in canteens except when seated at a table to eat or drink.
Current Social Distancing Requirements The Site Operating Procedures should be implemented on construction sites and workers should maintain a distance of two metres, or one metre with risk mitigation where two metres is not viable. National guidance on Social Distancing in England, Scotland, Wales and Northern Ireland should be adhered to off- site. Local restrictions, which could be different to national guidance, may also apply. Charles Anthony House, Manston Road, Margate, Kent CT9 4JW E-mail. [email protected] Tel. 01843 821 555
