1. Introduction

1.1 The brief Waterman Infrastructure & Environment Limited (“Waterman”) was instructed by Quattro (UK) Ltd (“the operator”) to prepare an application for an Environmental Permit (EP). To authorise planned waste operations at Quattro Site Southall on land forming part of the former Western International Market, Southall Lane, Hayes, UB2 5XJ (“the site”). The EP application seeks to vary an existing EP1. To a bespoke EP for treatment of solid, mixed non- hazardous and inert and excavation wastes from construction and demolition sources (“C&D wastes”). Including transfer of inert and excavation wastes and municipal wastes. With an annual throughput of 150,000 tonnes per year. For activities that include the storage and handling of combustible waste, a fire prevention plan (FPP) is required. The FPP must be submitted for assessment with the EP application, if an approved FPP is not already in place for the site. This document comprises the FPP.

1.2 Report scope The Environment Agency (EA) has issued specific guidance on FPP2 (EA FPP Guidance). This FPP has been prepared taking account of the guidance. The document is structured in line with “Writing your Fire Prevention Plan (FPP) – The basics” issued by the EA3.

1.3 Limitations and constraints The FPP has been developed with the operator. It is based on site infrastructure built for the purpose, and on known management practices. Measures for waste management, storage and active fire-fighting are as planned. The assessment was undertaken in accordance with the scope agreed between Waterman and Quattro (UK) Ltd, as documented in Waterman’s fee letters (WIE12765-100-190514-SO-FeeProp dated 14 May 2019, WIE12765-100-191025-BL-FeePropOS dated 25 October 2019 and WIE12765-100-191209-SO- FeePropOMP dated 19 December 2019), and with Waterman’s standard Terms of Appointment. The benefit of this report is made to Quattro (UK) Ltd. Waterman has endeavoured to assess all information provided to them during the preparation of this document but makes no guarantees or warranties as to the accuracy or completeness of this information. The conclusions resulting from this study are not necessarily indicative of future conditions or operating practices at or adjacent to the site. The document has been prepared in consultation Vesta Fire Risk Management (VFRM). Findings are based on information obtained, including at a site visit (11 July 2019) accompanied by VFRM. Waterman have relied on information supplied by Marks Heeley4 regarding site surfacing, drainage, boundary treatment and building construction.

VFRM has provided recommendations to the client regarding means of escape from the waste management building, and on the management plan required to meet the guidelines set out in BS99995. This is without prejudice to any compliance assessment in relation to the Regulatory Reform (Fire Safety) order 2005 for the waste management building and picking areas. Which should be assessed by a Fire Risk Assessor. Waterman has not commented on these requirements. Which are outside the scope of the Environmental Permitting regime (EPR) and of the FPP.

2. The site

2.1 Site activities

2.1.1 C&D waste plant The waste recycling facility includes a construction and demolition (C&D) waste plant (“the C&D plant”). The plant is housed in a three-sided, roofed waste management building6, constructed of concrete walling, steel frame and panelling. A mechanical treatment plant (C&D plant) is operated within the building, and linked covered picking station. The incoming waste will be mixed C&D waste from household, building trade, commercial development and utility infrastructure projects. The plant will consist of conveyors, a trommel, screens, blowers and magnets, and a picking station. The treatment process will separate out wastes for recovery including metals, wood, green waste and hardcore (hard materials such as lumps of concrete, bricks and blocks). The layout of waste storage areas is shown on the site layout plan provided in Appendix B (FPP Site Layout Plan). The site will accept up to 150,000 tonnes of waste per year. Wastes received will comprise solid, mixed non-hazardous and inert construction, demolition and excavations wastes. Vehicles carrying the wastes to site will typically include vans, skip lorries and tippers. Pre-acceptance procedures are applied. Loads are inspected at the weighbridge on arrival. The mixed wastes will contain on occasion wastes which are considered to be hazardous such as gas cylinders or items of waste electrical and electronic equipment (WEEE) and so on. Such wastes will be considered to be contraries, and will be quarantined pending removal from site. A 12 yard skip in the yard is provided for this. Labelled “incidental waste” on the FPP Site Layout Plan. Incoming wastes will be tipped in the waste management building. An initial sort will be conducted whereby a mechanical grab will remove wastes unsuitable for processing (either unacceptable wastes as above, or wastes that are too long or big for processing such as lengths of timber, or mattresses). Green waste is removed as far as possible at this stage and stored in the dedicated green waste skip shown on the FPP Site Layout Plan. The remaining waste will then be processed through the C&D plant. This includes screening via trommel to remove fines. A magnet removes ferrous metal and a blower removes light materials. The remaining wastes will pass into the picking station. Staff in the picking station will positively pick different waste types including non-ferrous metal and wood. Dropping the items through the floor into 40 yard skips beneath. Other materials including plastic, paper and cardboard are put into the skips for “general” waste. Which leave site for recovery in refuse derived fuel (RDF). At the end of the conveyor belt, a further blower removes light items too small to pick (e.g. bits of wood). The remaining hardcore drops off a conveyor into the outgoing hardcore bay. Full skips from beneath the picking station will be removed directly from the site, preferentially. Or held for short durations along the eastern side of the site pending collection. Bays for hardcore and trommel fines coming off the C&D plant, and bays for wood removed prior to processing are provided, external to the waste management building. Wastes from these bays will be loaded into bulker or tipper trucks for removal from site.

6 Details of the building structure can be found in Appendix C. 3 Fire Prevention Plan Document Reference: WIE12765-100-R-5-3-6-FPP

\\H-lncs\wiel\Projects\WIE12765\100\8_Reports\5. FPP\WIE12765-100-R-5-3-6-FPP.docx

2.1.2 Inert and excavation waste storage The site also runs an inert and excavation waste transfer operation within the permitted activity. Inert and excavation wastes are considered to be non-combustible. The location of the storage area for these wastes is shown on the FPP Site Layout Plan. The operator also stores aggregates (non waste) on the site for its commercial operations. The bays provided for storage of these materials on site has been considered only in terms of the site layout.

2.1.3 Municipal wastes storage Municipal wastes including black bag waste and street sweepings have been included in the list of wastes for the EP. This is for contingency. So that the site can provide temporary storage capability for municipal waste contracts, if required. For instance, for local authorities including London Borough of Hounslow (LBH). Storage of these wastes does not occur at the time of this EP variation application. However, these wastes (“municipal wastes”) have been referred to and accounted for throughout the written management system documents developed for this application. To demonstrate the operator is prepared with appropriate environmental controls in place to accept these wastes. If this activity occurs. Black bag waste will be stored in the waste management building. Street sweepings will be stored in one of the wood bays in the eastern external yard area.

2.2 Objectives of the FPP The purpose of the Fire Prevention Plan (FPP) is to meet three key objectives;  minimise the likelihood of a fire happening;  aim for any fire to be extinguished within 4 hours; and  minimise the spread of fire through the site and to neighbouring sites. The risk of fire from handling and storing combustible material on site is reduced by;  limiting the amount and storage duration;  limiting mixing and contamination; and  monitoring waste to ensure it is not hot.

2.3 Combustible wastes on site Combustible wastes on site relevant to the FPP include:

2.3.1 Non-combustible wastes on site Inert and excavation wastes stored in stockpiles within bays (sleeper walls). Quarantined (incidental) items such as gas bottles.

2.4 Site location and sensitive receptors

2.4.1 Site location and setting The site comprises a plot of land of approximately 1.73 hectares (ha) in size. It is located to the west of Southall Lane at National Grid Reference 510990, 178560. It was formerly occupied by the south-eastern end of an open-air market known as Western International Market. The site surroundings can be summarised as follows:  north: a large commercial unit occupied by Costco and a Virtus7 Datacentre. With car parking and Hayes Road beyond;  east: Southall Lane, Airlinks golf course and car park, and David Lloyd sports club;  south: undeveloped land with M4 beyond; and  west: the Hounslow waste depot8 (operated by Lampton 360) with Western International Market and A312 road beyond. Costco prepare food within their unit. Virtus operates servers and offices 24 hours a day with a controlled air environment. The nearest residential properties are located approximately 230m northeast along Convent Way and Wentworth Road.

Heathrow Airport The site is also approximately 2.7 km west of Heathrow Airport’s north runway – which has been considered in relation to smoke plumes from fire at the site. The operator’s detection and suppression system has been chosen to knock down a fire in the waste management building as quickly as possible. Limiting the potential size of a smoke plume in the event of a fire.

7 Virtus Hayes Limited. 8 Planning permission for the Hounslow waste depot was granted in May 2016 under P/2016/0685. A Land Contamination Assessment, undertaken by AECOM Limited in February 2016, was submitted to the Council as part of the planning application. 5 Fire Prevention Plan Document Reference: WIE12765-100-R-5-3-6-FPP

\\H-lncs\wiel\Projects\WIE12765\100\8_Reports\5. FPP\WIE12765-100-R-5-3-6-FPP.docx

Largest stockpile of combustible material: The largest amount of waste in one pile is the incoming non-hazardous waste tipped in the building prior to processing. The maximum volume of waste anticipated to be received and processed through the C&D plant in one day is 300m3 (cubic metres). This is the largest possible pile size and is used as the largest volume of waste stored together for worst case scenario planning (see section 4.8.2). Incoming waste would normally be tipped in two or more piles (each not more than 150m3)9. The total volume would accumulate in one day only if the plant were in shut down or failure. More than one day’s worth of infeed material would not be accepted, and contingency plans would be applied to redirect waste arriving the following day if necessary.

3.2 Storage duration Wastes stored in large quantities for long periods can begin to degrade, or the pressure in the centre of the stockpile can cause heat to be generated. In these circumstances exothermic reactions can occur and waste can self-combust. Incoming waste is stored for no longer than 72 hours (over a weekend). Target materials are moved for onward recovery when a load is built up. Retention time for these wastes is not longer than one month. Unwanted items are more challenging to remove for recovery on a commercial basis but will be removed as soon as is practicable. No waste is kept longer than six months10.

3.2.1 Stock rotation All incoming wastes are processed though the waste management building. No residues of incoming waste are left on the tipping floor. The operator wants to extract as much recoverable material as possible from all incoming wastes. The tipping floor, plant and bays beneath the picking station are cleared and swept weekly. The cages light material coming off the C&D plant, containment for the fines and ferrous metal are emptied when full and fully swept out. Inspection is part of the weekly environmental inspection. Skips beneath the picking station are either removed from site for onward recovery directly when full, or stored temporarily in the eastern external yard area pending collection. Material (hardcore, wood, trommel fines) in the storage bays on the eastern side is collected once a full load has accumulated. Any waste remaining in the bay is lifted and piled to form the start of the next pile / load. The bays walls and surfacing are checked whilst the bay is empty or near empty. The green waste skip is emptied (removed) at least once per month.

3.3 Monitoring and controlling temperature

3.3.1 Fire watch A site manager or foreman conducts a fire watch three times a day. 1) Fire check is conducted in the morning to ensure plant and operations start up correctly and that the logistics for the day are planned; 2) A further check is conducted in the middle of the day. To check for signs of heating in stored waste or

9 If municipal waste is being stored for transfer. This will be 1No. pile black bag waste (150m3 max) and 1No. incoming C&D waste pile (150m3 max). 10 This is the maximum retention time for all combustible waste given in the EA FPP Guidance. If waste is stored in the maximum pile sizes given in the guidance, additional monitoring must be applied if the waste is stored for longer than three months. But, the site’s maximum pile size is below this threshold. 10 Fire Prevention Plan Document Reference: WIE12765-100-R-5-3-6-FPP

plant, and hot exhausts. To identify any ignition risk developing. Problems arising will be corrected. Operatives will be assessing their work areas throughout, and before and after breaks. Site conditions will be accounted for, such as busy periods and hot weather. Corrective actions will be taken such as dampening down or resting and cooling plant engines; and 3) The site closedown check at the end of the day ensures that fire risk overnight is minimised – the site secure, clean, cool, locked and all materials and mobile plant are stored correctly. Plant and equipment are switched off (e.g. C&D plant). No wastes are retained long enough on site or at pile sizes large enough to necessitate temperature monitoring of specific wastes. Staff are alert to signs of heating (such as smoulder or excessive water vapour), as outlined in section 4.5.1.

3.4 Actions to limit self-heating

3.4.1 Wastes capable of self-heating In theory, each of the combustible wastes on site would be capable of self-heating if retained in large quantities for long periods of time or exposed to prolonged hot weather (see also 3.4.2 below).

Table 4: Preventing self-heating

Wastes capable of self-heating Reason Prevention measure A maximum pile volume of 300m3 is applied (usually 2No. piles each max. 150m3).

(See 3.4.2 green waste below).

These wastes are unwanted and removal from site is arranged as soon as practicable. Incidental wastes (including tyres, WEEE and mattresses) This skip will be covered in hot weather to provide shading. The skip is checked during daily fire watch checks. Water vapour and steam from this waste as it dries out should not be mistaken for smoke or signs of fire. Street sweepings contain a lot of Street sweepings organic matter. This can self heat. Waste will not be kept on site for longer than 3 days ordinarily. It is (municipal waste contract) Heating may be exacerbated in hot weather. The waste will also dry out. good practice to turn the waste in the bay once a day in hot weather to release heat13 from the centre of the pile. *see contingency measures for in the event of plant failure or break down.

3.4.2 Hot weather As above. Incoming C&D wastes, and municipal black bag wastes (when relevant) are stored in the waste management building and therefore sheltered from hot weather. The skips containing wood, general waste and metal, underneath the picking station are under cover and sheltered from the weather. In prolonged hot weather (2-3 consecutive days >25oC) the wastes stored externally in bays and skips will be checked for signs of heating. Site staff will look out for smouldering or excessive water vapour. The waste will be spread out in the quarantine area and dampened down if considered necessary. A mobile bowser14 and the wheel wash tank with hose are available for this purpose. The dust suppression misting system along the site boundary will be in operation in hot weather, adjacent to the bays on the eastern side.

13 Odour control is applied during this activity. 14 Mobile dust suppression unit. As shown in Site Condition Report Appendix A. Ref. WIE12765-100_GR_WS_A3A (September 2019). 12 Fire Prevention Plan Document Reference: WIE12765-100-R-5-3-6-FPP

3.5 Managing common causes of fire

Table 5: Common causes and mitigation

Cause of fire Prevention measures

Security measures reduce the risk of intrusion and arson; The whole site is provided with 3.0m high mesh security fencing. Along the northern boundary the site is additionally secured with 3.5m high sleeper (panel) and steel (upright) walling. The eastern boundary has a vegetated bank and a further 1.5m high fence along the perimeter boundary with the road. (Southall Lane). The site boundary will be checked on a daily basis. With any repairs carried out temporarily before the end of the working day. Permanently as soon as practicable. Any serious damage to the perimeter or boundary fencing will be recorded in the site diary. Arson The whole site is covered by CCTV15 which is viewed from the weighbridge office during operational hours and from the security hut overnight. The site is manned by a member of staff providing security watch out of hours. Maintenance staff are additionally present often in the evenings and at weekends. CCTV footage is recorded and stored for 3 months. The site is provided with flood lighting. The security watch completes a site walkover every 2 hours and scans tags along the route to record that this has been done.

Mobile plant on site include;  1No. 360o excavator;  1No. loading shovel;  1No. mini digger;  skip lorry (slave);  mobile bowser (dust suppression unit); and  mobile bowser (fuel). Maintenance and servicing of fleet is conducted off site at Quattro’s fleet maintenance Plant and equipment workshop (Iver). Start up checks are conducted by operatives. Three times daily fire watch includes checking for hot exhausts and the build-up of oil and dirt on machines. This includes fixed plant on site (C&D plant). Machines are switched off when not in use. If corrective action is needed while in use machines will be switched off, cooled and cleaned.

Machines are parked >6m from combustible waste or any other ignition sources when not in use e.g. during staff breaks and overnight.

All electrics on site are new at the time of setting up the site. All are installed and Electrical faults (including certified by a qualified electrician. There is a substation between the secondary and damaged) perimeter fencing on the eastern boundary.

15 117No. cameras (prior to the addition of the Fire Shield system in the waste management building). Cameras have infrared night vision (thermal imaging). 13 Fire Prevention Plan Document Reference: WIE12765-100-R-5-3-6-FPP

Cause of fire Prevention measures

Staff including out of hours have access to the switch room. Testing and checks are scheduled. Records are maintained. This is in accordance with the operators’ management system.

The smoking area is located outside the staff office / welfare facilities, on the side Smoking adjacent to the car park. Not near to combustible waste storage. Behind the sleeper wall from the inert and excavation waste.

No cutting or welding is conducted on site as part of the waste management operation. Hot works required for repair of plant and machinery is conducted in accordance with a Hot works (welding, cutting) hot works permit. This ensures that the area is checked before work commences and is free of ignition risks. The area is checked within an hour of work finishing to ensure no fire risk remains.

Industrial heaters There are no industrial heaters on site.

Mobile plant exhausts are checked by operatives when starting / stopping use. Engines are switched off when not in use. Hot exhausts Machines are parked >6m from combustible waste or any other ignition sources when not in use. The C&D plant motors will be checked three time daily during fire checks, when in use.

Space heaters are used in offices and the picking station (C&D plant). Electrics are Ignition sources (e.g. space subject to a regular testing schedule. Workspaces are cleaned weekly to ensure heaters, naked flame) combustible dust and fluff do not accumulate.

A mobile fuel bowser16 containing red diesel (7,000 litres) is retained on site for on site plant.

Leaks and spills of oil or fuel There are 2No. static tanks containing white diesel (27,000 litres and 25,000 litres). Static tanks are double skinned. Spill kits are provided and a spillage procedure is in place.

The occurrence of loose combustible waste is reduced by tipping incoming waste in the C&D plant building. Litter is blown into a cage or picked off by staff in the picking station from waste processed through the C&D plant. Build up of loose combustible Incoming loads transported by Quattro fleet vehicles are checked on collection and waste, dust and fluff covered if likely to contain litter or give rise to dust. The site surface is washed daily by a road sweeper. The site is checked daily by the site manager. Litter is picked from the perimeter fence once a week. Bays beneath the picking station and area around the C&D plant are checked and swept weekly.

Reactions between waste Any items with the potential to be unstable or cause reaction within a load will be (incompatible wastes, lithium rejected. If detected on pre-acceptance or inspection on the weighbridge the item will batteries) not be accepted. If detected on tipping, the item will be quarantined.

Mixed C&D wastes have limited potential to generate heat by the nature of the waste.

From household sources, it is possible that hot embers from barbeques, fires or outdoor Deposited hot loads heaters (chimeneas / wood-burning stoves) could occur in skips. If these are detected on tipping the load and the source of the heat will be spread on the quarantine area and hosed down.

If these are present in black bag waste from local authority / municipal waste contract sources. These will not be seen on tipping as the waste will be disturbed as little as possible17. The CCTV cameras at the weighbridge can see infrared (thermal imaging). The load will be inspected at the weighbridge using this method as far as possible. If any heat is evident. The load will be tipped in the quarantine area and water from the wheel wash, or the mobile water bowser will be applied to cool the load. It will be checked by staff and using infrared cameras before storage in the waste management building. Once in the building, the waste is monitored by cameras and the automated (foam) cannon with flame detection. If detected at the weighbridge, water from the wheel wash will be applied to the skip from the hose. The load will be tipped and inspected on the quarantine area.

4. Reducing the impact of a fire Waste handling techniques limit the potential size and magnitude of a fire should it occur.

4.1 Waste acceptance All customers are made aware in advance as to what wastes are acceptable at the site. All vehicles arriving at the site must stop at the weighbridge and report to the weighbridge office. First time visitors will be inducted at the weighbridge office site regarding site operational procedures. Customers will wait on the weighbridge to have the gross weight of the vehicle recorded. The driver will provide the waste transfer note to the weighbridge clerk detailing the source location, a description of the waste they are carrying, European Waste Catalogue (EWC) code and with vehicle registration number along with such further information as necessary to comply with legal “duty of care” requirements18 The weighbridge clerk will visually inspect the load, wherever possible, to ensure an adequate description has been provided. The type and quantity of waste will be recorded, with all tickets recorded and available for inspection during operational hours. Provided the weighbridge clerk is satisfied with the waste information provided, they will then direct the driver to the waste reception building for tipping. An operative in the building will then inspect the load when being tipped to ensure that the waste is visually acceptable. If the load is suspected of not complying with the site permit prior to tipping, the vehicle will be directed away from the tipping area for further checking and verification. The waste will be checked by the site supervisor. If the situation cannot be resolved then the load will be deemed unsuitable will not be allowed to tip. The vehicle will be turned away and a record made in the site diary. The EA will be made aware of the waste carrier and vehicle registration number. If a load is found to be unacceptable after tipping, if safe to do so it will be reloaded onto the delivery vehicle, the vehicle will be turned away and a record made in the site diary. The EA will be made aware of the waste carrier and vehicle registration number. If an unacceptable load cannot be reloaded for whatever reason, it will be isolated in the building for further checking and verification pending its removal from site. If the customer can be identified, they will be contacted to make such arrangements, a record will be made in the site diary. The EA will be made aware of the waste carrier and vehicle registration number.

4.1.1 Incompatible loads As in Table 5 above. Reactions between wastes or instability could be caused by items in household waste such as batteries, chemicals or gas cylinders. These will be rejected if discovered prior to acceptance or quarantined and removed from site as quickly as possible.

4.1.2 Hot loads As in Table 5 above. From household sources, it is possible that hot embers from barbeques, fires or outdoor heaters (chimeneas / wood-burning stoves) could occur in skips of waste. If these are detected on tipping the load and the source of the heat will be spread on the quarantine area and hosed down.

18 Section 34 Environmental Protection Act 1990 and regulation 35 Waste (England and Wales) Regulations 2011. 16 Fire Prevention Plan Document Reference: WIE12765-100-R-5-3-6-FPP

\\H-lncs\wiel\Projects\WIE12765\100\8_Reports\5. FPP\WIE12765-100-R-5-3-6-FPP.docx

If detected at the weighbridge, water from the wheel wash will be applied to the skip from the hose. The load will be tipped and inspected on the quarantine area. Municipal (local authority / contract) waste will be inspected prior to acceptance using the infrared CCTV cameras. As for as is possible.

4.2 Waste treatment Wastes are stored and handled with provision for managing wastes in the event of a fire. This includes separation between wastes and quarantines areas available for fire management.

4.2.1 Separation distances The waste management building is constructed with concrete slab flooring and concrete walls to 5m high. The building is provided exclusively for tipping of incoming waste, to be processed thorough the C&D plant. Each bay beneath the picking station is walled either side to house a skip to receive waste from the station above. The 4No. bays on the eastern side are walled to 3.5m high and a limit of 2.5m high waste storage is maintained to leave 1m freeboard to prevent fire spread. Waste is not allowed to egress the front of the bays. The green waste skip and incidental waste skip are located next to the bays in the eastern area (external).

4.2.2 Fire walls The waste management building (C&D plant) is provided with concrete base walls to a height of 5m. All bay walls for waste storage are specified to a fire resistance time of 120 minutes (eastern external yard area). The bays along the southern side of the waste management building (external) have been specified to this fire resistance as well. These bays are regularly used for storage of aggregates (non waste). Details of the building construction can be found in Appendix C.

4.3 Quarantine area A dedicated quarantine area is provided outside the waste management building (C&D plant). This is supported by silt box 4 (SB4), which should be isolated if the quarantine area is in use. The purposes of the quarantine area is:  spreading and cooling waste affected by fire;  storing affected waste prior to collection;  storing unaffected material to keep it out of the way during an incident; and  storing plant or other assets to keep them away from an incident. The quarantine area has 6m clear space all around.

\\H-lncs\wiel\Projects\WIE12765\100\8_Reports\5. FPP\WIE12765-100-R-5-3-6-FPP.docx

4.4 Storage within buildings and suppression systems

4.4.1 Fire Shield19 detection and suppression system The operator has installed an automated detection and suppression system in the waste management building. The system includes: A Foam Monitor (cannon)20 – with 360 degree nominal 40m throw. This has automatic fire detection and will detonate onto a fire detected within zoned areas. The cannon can be manually overridden and operated / directed from the office / security hut using the CCTV system. The foam used is biodegradable fire-fighting foam (Class A). The flame detectors used have high dust immunity. The system gives the advantages of reduced:  fire size;  smoke and ash release;  water usage;  damage to property; and  risk to human health and safety. Details of the system are provided in Appendix D.

4.5 Active fire-fighting

4.5.1 Detecting fires During operational hours fires would also be detected by site staff. The waste management building and site are viewed from the site office using CCTV. Fire will be detected even if there is no activity going on in the area at the time. A fire watch is conducted three times per day. As set out in section 3.3. Potential fires, and causes of fire, will be detected on arrival of waste at the site, as set out in section 4.1.

4.5.2 Out of hours detection Out of hours fires are detected by CCTV (thermal imaging cameras on the whole site and automated flame detection in the waste management building) and security staff. The security watch is manned by site operational staff. A walkover is conducted every 2 hours. The CCTV cameras are viewed from the security hut. The foam canon in the waste management building can be operated remotely via the CCTV system. The fire service will be called immediately to any fire. The staff are capable to shut off the site drainage and operate plant and machinery required to assist the fire service. To operate water supplies to provide initial response. In waste handling to minimise the spread of fire or to spread and cool affected waste. To remove unaffected waste, plant or assets to a safe place.

4.6 Type of fire

4.6.1 Building fire Fire-fighting beyond immediately reducing risk to people or property is not expected. The building should be evacuated and the fire service called immediately to any fire taking hold or discovered in the waste management building. The building walls are of concrete construction to 5m high. The structural steelwork has been treated with intumescent material (paint) to provide 120 minutes of fire protection. This should prevent early collapse of the structure allowing fire-fighting, cooling and waste removal for longer. The walls beneath the steelwork meet the same 120 minutes of fire protection. Damage to the building is expected to be limited due to its construction, and by the Fire Shield detection and suppression system fitted. The size of the infeed stockpile also limits the size of a potential fire. The directional foam cannon would knock down a fire in the first instance, limiting its size and spread. The fire service would fight the fire from the front of the building using fire appliances and water supplied by the hydrant. Fire extinguishers and on site water supplies (water bowser) are available to deal with any small incident. Unaffected waste can be moved to a place of safety during the incident, to protect property and prevent fire spread. Once the fire is under control. Burned waste can be moved to the quarantine area for further spreading and cooling. The drainage will be locked off during the incident and clean up.

4.6.2 Skip fire A skip fire underneath the picking station or affecting the skip of incidental or green waste will be responded to rapidly. Using the water bowser, or on site water supplies. The skip will be deluged / filled with water. The skip will be isolated, either by removing the skip to the quarantine area, or moving surrounding skips to a safe location. Once the fire seems to be out, the skip will be tipped up in the quarantine area and the contents spread. More water will be used if necessary to ensure all the waste is cooled / extinguished. The waste will be classified and stored for disposal in a skip. The skip affected in the incident will be washed out and checked, and sent for repair or replaced if necessary. The drainage will be locked off before the skip is tipped up and during the clean-up.

4.6.3 Bay fire A fire in a bay on the eastern side can be initially tackled using nearby water supplies (e.g. mobile water bowser). The bays are constructed and managed such that fire would not spread between bays for a period of at least 120 minutes. Once the fire is under control, at least half the material should be removed to a quarantine area for further spreading and cooling. Spreading and cooling should occur in the bay as well. Material in the adjacent bay can be removed to a quarantine area or safe place to avoid damage or undue soaking which may reduce its quality for onward recovery. The drainage supporting the bay and the quarantine area used should be locked off during the incident and clean up.

19 Fire Prevention Plan Document Reference: WIE12765-100-R-5-3-6-FPP

\\H-lncs\wiel\Projects\WIE12765\100\8_Reports\5. FPP\WIE12765-100-R-5-3-6-FPP.docx

Even if a fire has been extinguished quickly. The fire service will be called upon to make safe and check the integrity of the area, site infrastructure or plant and ensure no further risks are present.

4.7 Water supply There are several options for water supply available at the site.

4.7.1 Hydrant A water hydrant is located on Southall Lane. The flow rate is confirmed as 2,000 litres per minute (lpm) day rate and 3,000 lpm potential overnight. This is confirmed by Affinity Water21. The hydrant will be used by the fire service in the event of a serious fire.

4.7.2 Tanks 8No. 10,000 litre water tanks are provided for the waste management facility. Primarily these supply the dust suppression system and foam cannon system.

4.7.3 Wheel wash water Cooling water is available from the wheel wash water tank (18,000 litres). For any incoming load of waste or incident at the weighbridge. The tank is open and permanently filled with water, supplied by the rainwater harvesting / recycling tanks attached to the CBP. A hose is attached for use at the weighbridge.

4.7.4 Mobile bowser A mobile water bowser22 is kept on site. This can be used for dampening down, or filling a skip to control potential incidents.

4.8 Fire water containment

4.8.1 Containment capacity The drainage scheme23 shows that with the system shut off, the site would hold up to 2,700 m3 of fire water. 2.7 million litres. This is ample for any plausible worst case scenario. A water supply of 2,000 lpm for every 300 m3 of waste is required. Note, 2,000 lpm can be supplied from the hydrant. The drainage for each area of the yard can be isolated by locking off the silt trap (box). The drainage from the waste management building floor is isolated to an underground tank. Once the volume held by the tank and building floor were breached, water would flow to silt box 4 (SB4). The drainage for the whole site can be locked off at the pumping station.

4.8.2 Worst case scenario The worst case scenario fire for the FPP is one involving the biggest stockpile. The incoming waste pile in building is 300m3 maximum. The incoming waste would ordinarily be in two piles of approximately 150m3 each. But 300m3 is used for the worst case scenario in this FPP.

21 Confirmed to VFRM July 2018. 22 Dust suppression unit. 23 Marks Heeley H11930-PC6 Drainage scheme No.11 as built (Appendix B). 20 Fire Prevention Plan Document Reference: WIE12765-100-R-5-3-6-FPP

\\H-lncs\wiel\Projects\WIE12765\100\8_Reports\5. FPP\WIE12765-100-R-5-3-6-FPP.docx

The daytime flow rate from the hydrant is 2,000 lpm. A single fire appliance can pump 2,000 lpm. If the hydrant in use were the limiting factor to the flow rate applied by the fire service. 120,000 litres per hour should be approximated. Water from the 10,000 litre tank and water bower would be used additionally for cooling activities.

4.8.3 Release of water Potentially contaminated fire-fighting water must be held until it’s release is authorised. See section 5.1.1 below.

21 Fire Prevention Plan Document Reference: WIE12765-100-R-5-3-6-FPP

\\H-lncs\wiel\Projects\WIE12765\100\8_Reports\5. FPP\WIE12765-100-R-5-3-6-FPP.docx

5. Contingency for during and after an incident

5.1 During

5.1.1 Shut off drainage The drainage must be locked off immediately in the event of a fire. This is to prevent unauthorised release of potentially contaminated fire-fighting water. The drainage for the site can be locked off at the pumping station. And / or each individual silt trap (box) can be locked off to contain water from a specific area. The silt box for the quarantine area should be locked off individually when in use. This is silt box 4 (SB4) – quarantine area. Silt Box 5 (SB5) can also be shut off individually if fire water is present in the area. Contained water should be released only if agreed with Thames Water Utilities Ltd. Otherwise, tankered away under contract for disposal.

5.1.2 Divert wastes During an incident, wastes arriving or due to arrive can be diverted to alternative Quattro facilities. Access to the waste recycling facility, and the location of the quarantine area means that the incident is expected to be managed without impacting the operation of the CBP (see section 5.2.1 below).

5.1.3 Remove equipment and assets to safety A quarantine area is maintained for use in an incident. Plant and skips of waste can be stored in the LGV and mobile plant parking area. Away from the C&D plant and incident.

5.1.4 Notify neighbours The site design and housing of the C&D plant within the waste management building is intended to prevent any potentially polluting activity, such as dust raising or fire from affecting neighbouring commercial properties. However, Costco or Virtus Datacentre may be informed following a serious fire as a courtesy. The security staff will have access to a telephone and will be issued with emergency contact numbers to cover all eventualities. The numbers available will include:  Environment Agency;  Hounslow Council Environmental Health Department;  Quattro contacts;  local hospital;  local police;  local fire and rescue service;  emergency gas;  emergency electricity;  emergency water and sewerage undertaker;  on call tanker supplier;  Costco; and  Virtus Datacentre.

\\H-lncs\wiel\Projects\WIE12765\100\8_Reports\5. FPP\WIE12765-100-R-5-3-6-FPP.docx

5.2 After

5.2.1 Steps to remain operational Access to the C&D plant in the event of a fire is structured such that the CBP would remain operational as far as possible. A traffic management plan is in place. An incident requiring the evacuation of the C&D plant may require evacuation of the whole site, whilst the fire service is in attendance. As soon as the site is released by the fire service the CBP operation can commence. The CBP operation would not be affected at all by a small incident (e.g. skip fire). The C&D plant, waste storage, quarantine areas and access are such that the waste management operation is separate from the CBP. The site access, weighbridge, parking and other storage areas would not be affected by an incident in the waste management area. The waste management operation would be temporarily suspended only in the event of a serious fire affecting the C&D plant or building. The Fire Shield detection and suppression system employed is designed to minimise the extent of a fire and any damage caused. Affected waste would be held in the quarantine area until suitable disposal is arranged. If the C&D plant has been damaged. Processing can take place at Quattro’s Horn Lane facility24 while the plant is repaired / integrity checked and cleaned after an incident. The fire suppression system will be checked and restored prior to recommencement.

5.2.2 Decontaminating and restoring the site Fire-fighting water captured on site will be tankered away under contract, and the silt trap and oil and water separator emptied. Or tested and released to sewer on agreement with Thames Water Utilities Ltd. Any burned or affected material will be classified and sent for specialist recovery or disposal if necessary. The integrity of site surfacing and infrastructure e.g. drain covers affected will be checked and reinstated as necessary. All plant and equipment will be thoroughly inspected, and repaired or replaced if necessary to restore function. Buildings and walls affected will be repaired as soon as is practicable. Waste handling and storage will be conducted with suitable separation whilst this containment is not available.

24 In the future the CCTV system at Southall Lane may be able to be viewed from another Quattro site. This would enable the site, and waste storage to be checked remotely, in the event of temporary closure of the operation. 23 Fire Prevention Plan Document Reference: WIE12765-100-R-5-3-6-FPP

6. Using the fire prevention plan

6.1 Staff training Technically competent mangers on site are responsible for inducting and training all staff on the principles and practices of the FPP. The site foreman is responsible for ensuring:  water supply is maintained;  access and egress routes are maintained;  a quarantine area is maintained;  fire watches have been conducted;  all actions identified from daily checks are delivered; and  emergency action plans exist for all likely fire scenarios such as;

- skip fire (external); - skip fire (under picking station); - pile fire; and - fire in conveyor or other plant. Managers will ensure;  all records are maintained;  staff are regularly trained and rehearsed in their deployment and initial actions;  suitable records are kept of training and learning outcomes are actioned promptly;  there are always staff who can drive and operate plant available;  drainage shut off processes can be quickly undertaken 24 hours a day; and  overnight staff are equipped to respond to an incident of fire in the appropriate way (as outlined in section 5.1).

6.2 Regular drills and exercises A fire drill, testing different scenarios given in the FPP, will be carried out every 6 months. Testing procedures, response times and the robustness of resources. Exercises will include;  the drainage shut-off procedure; and  tipping and cooling a skip in the quarantine area. Contingency plans will be tested (as a desk study if real test not practical) including;  management of incoming and outgoing wastes in an emergency, and  access to the site in relation to the CBP operation. Results will be fed back and the FPP updated or amended accordingly.

6.3 Review of document The FPP will be reviewed and updated following any of these circumstances:  any change to operations (equipment, processing, throughput, material streams, acceptance procedures, etc);
