10.8 SOLID WASTE MANAGEMENT:
The Solid waste generated from the proposed project is envisaged to be disposed through Trash bins, Trash cover collection system & then through the municipal Garbage collection Trucks for further disposal. The solid waste would be initially segregated at source collection into Organic and Inorganic wastes and then kept ready for disposal. The volume of garbage produced from the Project is worked out as per the guidelines of IS 6924-1973.
QUANTITY OF SOLID WASTE GENERATED: Quantity of Refuse = 0.484 Kg/Person/day Total number of persons = 3000 Quantity of Refuse produced/Day = 0.484 X 3000= 1452 kgs/day. Inorganic Waste in the refuse = 580.8 kgs/day Organic Waste in the refuse = 871.2 kgs/day
Majority of the organic waste includes food waste & paper waste. The paper waste generated will be sold to scrap dealers while the food waste is collected in separate bins & disposed to municipal garbage trucks or sold out to vendors.
Conclusions:
The sewage treatment plant is designed based on the proven activated sludge process with sequencing batch reactor technology. The STP would be able to treat the sewage to the standards prescribed by the KSPCB with treated BOD5 levels less than 10 mg/L. The treated water can be used for the tertiary uses like gardening, floor & vehicle washing, toilet flushing, ground water recharge etc. The treated water is safe to come in contact as the chlorination is done to kill the bacteria. The rainwater harvesting proposed would not waste any rainwater and it will be used back to the maximum and the excess water will be used for the recharging of underground water. The water and waste water management and the solid waste management adopted by the developers would be one of the best in the interest of protecting the environment and in saving the natural resources.

ANNEXURE – 19 Environmental Management Plan
19.1 Environmental Management Plan:
Any establishment has certain impacts on the surrounding environment, which may be either beneficial or adverse. Therefore, such establishments will have to develop strategies to tackle its adverse impacts on the surrounding environment and it becomes imperative on the part of the project proponents to equip themselves with plans to combat such impacts.
A detailed Environmental Management Plan (EMP) in support of identified impacts of the proposed project has been prepared to foresee the environmental problems at the planning stage itself. Mitigation measures at the source level and an overall Management Plan at the site level are elicited to improve the surrounding environment.
The construction phase impacts are mostly short term, restricted to the plot area and not envisaged on the larger scale. In the operational phase the environmental impacts are due to continuous operation of the project, hence, the emphasis in the EMP is to minimize such impacts. The emphasis of the EMP development is on the mitigation measures for each of the activities causing the environmental impact and resource allocation for environmental management.
Following sections describe various environmental aspects and the environment management plan proposed for construction and operation phases.
19.2 Environmental Aspects And Management Plan
During Construction Phase
The major activities identified to cause impact of different degrees on the environment during construction phase are site clearance, transportation of construction materials and construction activities.
The following factors are given consideration to maintain good environmental quality during construction phase.
19.2.1 Air Environment
The construction activities would result in generation of fugitive dust. The fugitive dust shall be controlled by carrying out the construction, by barricading the site area by metal sheets and tarpaulin covers to a particular height. Intermittent spraying of water shall be ensured to reduce and control fugitive dust. The workers shall be provided with Personal Protective Equipment (PPE) such as nose masks and goggles to reduce impact on health.
During transportation of construction materials, trucks shall be covered with tarpaulin sheets to prevent the material from being air borne. The speed of the vehicle carrying material shall be regulated and periodic emission check for vehicles will be ensured. Regular maintenance and Periodic check for emissions of the construction equipment will be ensured.
19.2.2 Noise Environment
There will be some noise generation due to running of construction equipment and movement of vehicles carrying construction materials, which will be temporary in nature.
Better quality construction equipment with less noise generation will be used. The transportation vehicles and earth moving equipment shall be periodically checked and maintained for noise levels. The construction workers shall be provided with adequate PPE such as earplugs to reduce impact of high noise levels and working hours shall be imposed on them.
19.2.3 Water Environment
The average water requirement during the construction stage is estimated at 41 m3/day. This includes water for the construction activities like mortar mixing, curing etc. (31 m3/day) and for domestic purposes (10 m3/day) at site. Water requirement will be met through water tankers of private water supply agency. There will be no wastewater generation from the construction activities. However, there will be discharge of domestic wastewater to the tune of 8 m3/day, which will be disposed to septic tank and soak pit or to a mobile STP.
19.2.4 Land Environment
General earthwork excavation during the construction phase results in the loosening of the top soil. The excavated soil will be stacked properly at site and the same will be utilized for backfilling and green belt development. Proper compaction and stabilization of the same will be ensured. The surplus excavated earth shall be disposed to vendors for disposal at approved sites.
19.2.5 Socio Economic Environment
The proposed construction will immensely benefit the local populace due to the employment opportunities to about 200 peoples on an average. In addition, several indirect employment opportunities will be generated by other associated activities of the project.
The construction site would be provided with drinking water and adequate sanitation for the workers to allow proper standards of hygiene. These facilities would be connected to a septic tank and maintained to ensure minimum impact on the environment.
19.3 Environmental Aspects And Management Plan
During Operational Phase The Environmental Management Plan to be implemented during the operational phase is discussed under the following heads:
19.3.1 Air Environment
The main sources of air emissions in the operational phase will be HSD fired DG sets. The project proponent will provide HSD fired DG set of two numbers of 1000 KVA capacity. DG sets will be operated only during emergency and will not be in continuous operation. DG sets complying with the latest CPCB / MoEF Standards for Emission and Noise will be selected as prescribed as per the latest amendments from the MoEF.
The details of emissions from the DG sets operating during emergency are given below: Sl.No Stack Details DG Stack 1. DG set capacity 2 x 1000 kVA 2. Number of stacks 02 3. Height of each stack (m) 9.0 m AGL
Stack height of 9.0 m ARL shall be provided with the flues for the vent of gases. Provision will be made to enable monitoring of emissions if required. Note: The SO2 emissions rate is based on 0.5% Sulphur content in the fuel The stack height is H+6 m where H is building height where DG sets shall be installed.
19.3.2 Noise Environment
The major sources of noise generation at the operational phase are DG sets. The DG sets will be housed in an isolated, acoustically enclosed area where the access will be restricted as per CPCB guidelines. Provision of acoustic dampeners in foundations will be made. Personnel operating DG sets will be provided with earmuffs to prevent direct exposure to noise.
19.3.3 Water Environment
The total water requirement to meet the domestic consumption of the proposed project is estimated to be about 180 m3/day. The water requirement shall be met from BWSSB and treated sewage. Adequate water storage facilities shall be provided to store the water within the project premises to ensure potable water supply.
19.3.4 Domestic Waste Water Treatment and Disposal
Adequate drainage network system will be provided to collect the sewage from all the floors. The network will be provided with inspection chambers as per the requirement. The sewage collected through the network will be conveyed to the proposed Sewage Treatment Plant.
The wastewater generation is estimated to be about 162 m3/day. The project proponent Proposes to build a full-fledged Sewage Treatment Plant (STP) for treating the domestic wastewater. The STP will be based on sequencing batch Reactor with extended aeration through diffused aeration and will be in continuous operation.
Purpose details of the STP units are given in Table below. The sewage generated from all the floors will be collected through network of drains. The collected sewage will be routed to the STP through covered drains provided with inspection chambers.

All the STP-units will be made impervious with solid impervious material on both sides and bottom, so that there is no leakage from the Plant. Technical design details of the STP are enclosed as Annexure – 10 along with Form 1A. The treated wastewater, meeting KSPCB standards shall be used for tertiary purposes like greenbelt development and toilet flushing through closed pipelines within the complex. No discharge of the effluent shall be made outside the premises. Usage of treated wastewater for flushing will also decrease the fresh water requirement. Landscape details are appended as Annexure - 13.
ANNEXURE 20 Risk Assessment, Disaster Management Including Offsite & Onsite Emergency Plans
20.1 Introduction Environmental risk analysis in this annexure deals with the identification and quantification of risks the equipment and personnel are exposed to, from the hazards present in the area.
Risk analysis follows hazard analysis (Risk = Hazard x Probability of Occurrence). It involves identification and assessment of risks to the construction personnel and neighboring populations. This requires a thorough knowledge of failure probability, credible accident scenario, vulnerability of population etc. Much of this information is difficult to procure. Consequently, the risk analysis is confined to maximum credible accident studies. The subsequent sections shall address the identification of various hazards and risks in the operations, which will give a broad identification of risks involved.
20.2 Objective & Scope The objective of the study is to carry out Risk Analysis and prepare Disaster Management Plan / Emergency Preparedness Plans. The risk analysis/ assessment study covers the following:
(a) Identification of potential hazards associated with the fuel storage and their usage (b) Assess the overall damage potential of the identified hazardous events and impact zones from the accident scenarios; (c) Suggestions and recommendations on the minimization of the accident possibilities; and (d) Preparation of On-site and Off-site Emergency Preparedness Plan.
20.3 Hazard Identification The technique used for the Hazard Identification is Maximum Credible Accident (MCA) analysis, which allows identification of an accident with probable maximum damage distance. Following are the fuels used in the premises.
i. High Speed Diesel (HSD) Storage quantities of fuel are presented in following Table-21.1.
TABLE - 20.1 STORAGE OF FUEL
Sl.No. Fuel name Max. storage quantity 1 HSD 2000 Liters
Preliminary Hazard Analysis suggests that following hazards are present:
Table 20.2 PROBABLE HAZARDS IN THE PLANT
Hazard Type Description Fuel Storage HSD Spill and Fire
Fire Hazards Fire, Explosion and Toxicity Indexing (FE & TI) is a rapid ranking method for identifying the degree of hazard developed by DOW chemical company. Using the Dow‟s Fire and Explosion Index (F&EI), the Risk/hazard is calculated from:
F&EI = MF x (GPAH) x (SPH)
Where MF – Material Factor represents the flammability and reactivity of the substances, GPAH is general process hazards and SPH is special process hazards. (GPAH) x (SPH) represents hazard factor. The degree of hazard potential is identified based on the numerical value of F&EI as per the criteria given in Table 21.3.
Table – 20.3 FIRE AND EXPLOSION INDEX
F&EI Range Degree of Hazard 0-60 Light 61-96 Moderate 97-127 Intermediate 128-158 Heavy 159-up Severe
For Fuels the F&EI is approximately estimated to be less than 60 (30 to40). This means it poses light degree of Hazard.
Following Table-20.4 provides the details of the identified Potential Hazards and the systems suggested to minimize the hazards.
Table 20.4 PREVENTIVE SYSTEMS PROPOSED IN THE BUILDING
Unit Hazard Identified Provision HSD Fire As per TAC rules for water spray system & small cylinders 1998. Unloading Trucks Fire/Explosion Separate Un-loading gantry Firefighting systems
20.4 Maximum Credible Accident Analysis (MCA) The MCA scenarios were short-listed based on the storage quantities and properties of the fuels (hazard identification). MCA analysis studies were conducted for the following scenario “Pool fire due to rupture / leakage and accumulation of fuel”.
20.4.1 Fire Damage A flammable liquid in a pool will burn with a large turbulent diffusion flame. This release heat is based on the heat of combustion and the burning rate of the liquid. A part of the heat is radiated while the rest is convicted away by rising hot air and combustion products. The radiation may heat the contents of a nearby storage to above its ignition temperature and thus result in the spread of fire. The radiation may also cause severe burns or fatalities of dwellers / workers or fire fighters located within a certain distance. Hence, it will be important to know beforehand the damage potential of a flammable liquid pool likely to be created due to leakage or catastrophic failure of a storage or process vessel. This will help to decide the type of protective clothing for the workers/fire fighters, the time they can be in vicinity of the fire (without and significant danger to life and health), the fire extinguishing systems needed and the protection needs for the nearby storage/process vessels. Tables -20.5 and 20.6 present the damage effect on equipment at different thermal radiation levels.
Table 20.5 DAMAGE DUE TO INCIDENT RADIATION INTENSITIES
S. No. Incident Radiation Type of Damage Intensity (kW/m2) Damage to Equipment Damage to People 1. 37.5 Damage to equipment 100% lethality in 1 min. 1% lethality in 10 sec. 2. 25.0 Minimum energy required to ignite wood at indefinitely long 50% Lethality in 1 min. Significant injury in 10 exposure without a flame sec.
3. 19.0 Maximum thermal radiation intensity allowed on thermally -- unprotected adjoining equipment 4. 12.5 Minimum energy to ignite with a flame; melts plastic tubing 1% lethality in 1 min. 5. 4.5 -- Causes pain if duration is longer than 20 sec, however blistering is un-likely (First degree burns) 6. 1.6 -- Causes no discomfort on long exposures

For barrels storage, it is assumed that the fuel leaks due to barrel failure or rupture develops into a pool and gets ignited (Pool Fire).
Following are the assumptions of the MCA analysis:
it is assumed that no fire detection and mitigation measures are initiated; secondary containment (dykes) that will confine flow of liquid and liquid absorption into the ground is not considered; secondary fire at public road is not likely to happen, since it is away from the fuel storage area; the effect of smoke on reduction of source radiation intensity has not been considered; therefore hazard distances calculated tend to be conservative; and Shielding effect of intervening trees or other structures has not been considered.
Properties of Fuels Considered For Modeling Scenarios
Properties of solvents and fuels used for modeling are presented in Table -20.7.
Table 20.7 PROPERTIES OF SOLVENTS AND FUELS CONSIDERED FOR MODELLING
S. No. Fuels Molecular Weight Boiling Point oF Sp. Gr. Kg /kg.mol 1 HSD 114 (approx) >350 0.80
Based on the above fuel properties, first the likely case of continuous spill for the fuel was modeled to arrive at the damage distance due to fire. Two critical damage distances were selected for presentation corresponding to 19 and 37.5 kW/m2. Following Table-20.8 presents the pool fire damage distance due to continuous spill.
TABLE- 20.8 OCCURRENCE OF DAMAGE DISTANCE FOR VARIOUS RADIATION INTENSITIES FOR FUELS (CONTINUOUS SPILL)
Fuels Damage distance in m. 19.0 kW/m2 37.5 kW/m2 HSD 7 10 Note: 19.0 kW/m2 is the maximum thermal radiation intensity allowed on thermally unprotected adjoining area. 37.5 kW/m2 is the radiation to cause damage to adjoining area. The leakage is considered as continuous at the spill rate of 10 liters per second.
In the building premises, HSD shall be stored in barrels near the DG sets. This is only the specified fuel storage area.
21.4.2 One Fuel storage area for HSD
A very unlikely worst case scenario is spread of fire in the entire storage volume in a fuel storage area. These could be possible as in case of major accident, natural calamity, sabotage or war. The fire will spread in the storage areas. For which the damage distance is calculated considering instantaneous fire of entire volume of fuel corresponding to storage capacity. As identified in earlier section,
TABLE- 20.9 OCCURRENCE OF DAMAGE DISTANCE FOR VARIOUS RADIATION INTENSITIES FOR FUELS (INSTANTANEOUS SPILL AND FIRE)
Fuel storage Storage Volume Damage distance (in m) (total capacity of all 19.0 kW/m2 37.5 kW/m2 barrels in storage room m3) HSD Barrels 5.0 39 58
20.5 Comments and Recommendations The MCA analysis of all storage contemplated in the plant clearly reveals that the major damage and fatality would occur in a top event of failure of all the HSD barrels. The damage distance is confined within the storage area. In case of an accident major damages are envisaged due to fire, controlling both ignition and spreading of fire becomes very critical for building and personnel safety. In the worst case scenario the damage due to fire will be restricted within the premises as the maximum damage distance equivalent to 37.5 kW/m2 is 150 meters from the center of the HSD storage.
Adequate fire detection and protection systems shall be installed to handle such emergencies as suggested in Table -20.10.
TABLE- 20.10 FIRE PROTECTION SYSTEM OF THE BUILDING
Suggested System For unloading area (Fuel), automatic detection system and manually operated medium velocity water spray system along with foam system shall be provided. An adequate number of portable chemical fire extinguishers shall be installed at suitable locations throughout the building. The extinguisher will be used during the early stages of fire to prevent spreading. Hydrant system covering the entire plant including all important auxiliaries and buildings shall be installed. The system should be complete with piping, valves, hoses, nozzles, and hydrants valves etc. All electrical fittings shall be of flame proof type.
General The study is based on assumptions that the storage facilities are designed, constructed and operated in accordance with the safe engineering practices and standards. It is recommended that strict adherence to the standards, accepted practices and operating maintenance & safety procedures are followed not only during the construction of the building but also throughout the life of the building.
The individual chance of fatality to a person outside the boundary due to an unlikely event of full-fledged pool fire in the fuel storage area is estimated to be 1.7 x 10-7 to 2.2 x 10-7 (based on historical data). This level of risk compares favorably with other voluntary/non-voluntary risks undertaken and may be considered acceptable.
Non-essential personnel shall be located away from the construction area. These include office staff, administration, accounts etc. and they should be restricted to the administrative building. The main construction area within the premises should be marked as safety zone and only construction personnel, and authorized staff/visitor should be allowed to enter in this area. Any person entering this area, be it visitor or plant personnel must be equipped with safety gadgets and must be made aware of the assembly points.
The safety instructions and safe operating conditions for the DG sets recommended by the manufacturers / vendors should be strictly followed.
Maintenance plays a vital role in proper upkeep of the building. An equally important function is monitoring of DG sets and fire control equipment, pipeline and machinery. Adoptions of the systems like thickness survey (including supports), maintenance history cards, and preventive maintenance practices will not only improve plant performance but also safety. It should be pointed out that the failure rates of equipment and pipes are influenced by the maintenance practice followed. When the building starts aging, it is suggested that due attention be given to this aspect when formulating a maintenance strategy.
20.6 On-Site Emergency Preparedness Plan The On-site Emergency Management Plan (OEMP) is aimed to ensure safety of life, protection of environment, protection of building. At the same time also addresses all the requirements of Environmental Protection Act Schedule –11.
Planning Factors The OEMP is based on certain assumption that might develop in the event of accidents in any of the construction activities. These assumptions are advance judgments concerning what might happen in the event of accidents, spill or release. The earlier sections on risk assessment provide us an insight of the different accident scenarios. Following are the emergencies envisaged in the plant.
A situation of fire at the fuel storage area Structural failures Contamination of food/water; and Sabotage/Social disorder Loss of Containment
Emergency Action plan: The following sections will form and shall be adopted as the emergency action plan by including relevant details. E.g. Name of the personnel, phone nos. etc.
Emergency Organization It is recommended to set-up an Emergency Organization, which would be headed by a senior executive who has control over the affairs of the construction activities. He would be designated as Site Controller. He would be assisted by Incident Controllers. Two incident controllers, one for the storage area and other for transport (loading, unloading etc.) are recommended. In the case of utilities, open areas, which are not under the control of the Construction Heads, Senior Executive responsible for maintenance of utilities would be designated as Incident Controller. All the Incident Controllers would be reporting to the Site Controller.
Each Incident Controller would organize for himself, a team responsible for controlling the incident with the personnel under his control. The person responsible for Control room would be reporting officer, who would bring any incidence to the notice of the Incident Controller and Site Controller.
Emergency coordinators would be appointed who would be responsible for firefighting, rescue, rehabilitation, transport and provide essential and support services. For this purpose, the services of Security, Personnel Department and Essential services personnel would be engaged. All these personnel would be designated as Key personnel.
Necessary electrical supervisor, electrical fitters, pump house in-charge and other maintenance staff would be drafted for emergency operations. In the event of power or communication system failure, some of staff members in the office would be drafted and their services for transmitting vital messages. All these personnel would be declared as Essential Personnel.
Emergency Communication Whoever notices an emergency situation (visual or through any detection device) such as fire, fuel leakage etc. they would be required to inform their immediate superior and Emergency Control Centre. The security cabin is declared as the Emergency Control Centre (ECC). The person on duty at the Emergency Control Centre would appraise the Site Controller in event of an emergency. Site Controller verifies the situation from the Incident Controller of that area or the reporting officer and takes a decision about an impending On Site Emergency. This would be communicated to all the Incident Controllers and Emergency coordinators. Simultaneously, the emergency warning system would be activated on instructions from the Site Controller.
Emergency Responsibility a) Site Controller On receiving information about emergency he would rush to Emergency Control Centre (ECC) and take charge of ECC and the situation and; Assesses the magnitude of the situation on the advice of Incident Controller and decides, Whether the affected area needs to be evacuated, Whether personnel who are at assembly points need to be evacuated, Declares Emergency and orders for operation of the emergency siren, Organizes announcement by public address system about location of emergency, Assesses which areas are likely to be affected, or need to be evacuated or are to be alerted, Maintains a continuous review of possible development and assesses the situation in consultation with Incident Controller and other Key Personnel as to whether shutting down the plant or any section of the plant is required and if evacuation of the persons are required,

b) Incident Controller Assembles at the incident control team. Directs operations within the affected areas with the priorities for safety to personnel minimize damage to the building and environment and minimize the loss of materials. Directs the shutting down and evacuation of building and areas likely to be adversely affected by the emergency. Ensures that all key personnel help is sought. Provides advice and information to the Fire and Security Officer and the Local Fire Services as and when they arrive. Ensures that all non-essential workers/staff of the affected areas are evacuated to the appropriate assembly points, and the affected areas are searched for causalities. Attempts to preserve evidence so as to facilitate any enquiry into the cause and circumstances which caused or escalated the emergency. Co-ordinates with emergency services at the site. Provides tools and safety equipment to the team members. Keeps in touch with the team and advise them regarding the method of control to be used. Keeps the Site Controller informed of the progress being made to control the emergency Emergency coordinator - Rescue, Fire Fighting Helps the Incident Controller in controlling the emergency. Ensure fire pumps are in operating conditions and instructs pump house operator to be ready for any emergency with standby arrangement. Guides the firefighting crew i.e. firemen, trained persons and security staff. Organizes shifting of the firefighting facilities to the emergency site, if required. Takes guidance of the Incident Controller for firefighting as well as assesses the situation and organizes for the outside help, if required. Arranges to control the traffic at the gate and the incident area. Directs the security staff to the incident site to take part in the emergency operations under his guidance and supervision. Evacuates the people from the building or nearby areas as advised by Site Controller. Searches for casualties and arranges for proper medical aid for them. Assembles search and evacuation team. Arranges for safety equipment for the members of his team. Decides which path the evacuated workers should follow.
c) Emergency coordinator In the event of failure of electric supply and therefore internal telephone, sets up communication point and establishes contact with the Emergency Control Centre (ECC). Organizes medical treatment of the injured and if necessary will shift the injured to nearby hospitals.

Makes sure that all safety equipment is made available to the emergency team. Assists Site Controller with necessary data and co-ordinates the emergency activities. Assists Site Controller in updating emergency plan, organizing mock drills, verification of inventory of emergency facilities and furnishing report to Site Controller. Ensure availability of canteen facilities and maintenance of rehabilitation center. He will be in liaison with Site Controller/Incident Controller. Ensure transportation facility. Ensures availability of necessary cash for rescue/rehabilitation and emergency expenditure. Controls rehabilitation of affected areas on cessation of emergency. Makes available fuel for transport vehicles engaged in emergency operation.
Emergency coordinator – Essential Services He would assist site Controller and Incident Controller. Maintains essential services like Diesel Generator, Water, Fire Water, Power supply for lighting. He would ensure that power for essential services and utilities are not affected, in the event of an emergency. Gives necessary instructions regarding emergency electrical supply, isolation of certain sections etc. to reporting officer and electricians. Ensures availability of adequate quantities of protective equipment and other emergency materials, spares etc.
General Employee An emergency becomes more enhanced and pronounced when workers responsible for building construction/maintenance or the occupants, continue with their work / stay despite the sounding of an emergency. If anyone is not assigned any responsibility, he / she should proceed to assembly points and await instructions. He /she should not resort to spreading panic, but rather assist emergency personnel.
Emergency Facilities Emergency Control Centre (ECC) The suitable location from where clear view of the plant is possible OR the control room can be designated as Emergency Control Centre. All the Site Controller/ Incident Controller Officers, Senior Personnel would be located here or have access to the ECC.
The following information and equipment are to be provided at the Emergency Control Centre (ECC).
Intercom and telephone Safe contained breathing apparatus Fire suit/gas tight goggles/gloves/helmets Public address megaphone, hand bell, telephone directories Building layout, site plan Emergency lamp/torch light/batteries Plan indicating locations of sources of safety equipment, road plan, assembly points, rescue location, vulnerable zones and escape routes. Emergency shut-down procedures Nominal roll of employees List of key personnel, essential employees, and emergency coordinators Duties of key personnel Address with telephone numbers and key personnel, emergency co-coordinators and essential employees. Important address and telephone numbers including Government agencies, neighboring industries and sources of help, outside experts, chemical fact sheets population details around the factory.
Assembly Points Number of assembly depending upon the building location would be identified wherein workers / occupants who are not directly connected with the disaster management would assemble for evacuation. Emergency breathing apparatus and other facilities such as water etc. would be organized at the assembly points.
Emergency Power Supply Building facilities can be connected to a Diesel Generator (auto mode) for water pumps, plants lighting and emergency control center. Administrative building and other auxiliary services are connected to emergency power supply. In all the blocks flameproof type emergency lamps would be provided.
Location of Wind Sock On the top of the building visible wind socks would be installed to indicate wind direction. In case of emergency building occupants / workers should evacuate by running at 90 degrees to wind direction (and not opposite to wind direction).
Emergency Medical Facilities Stretchers, gas masks and general first aid materials for dealing with, fire burns etc. would be maintained in the first aid center as well as in the emergency control room. A range of medicines should be maintained. Breathing apparatus and other emergency medical equipment should be provided and maintained.
Emergency Actions a) Emergency Warning The procedure for communication of emergency should be made familiar to the people, inside and outside the building. An identifiable emergency warning system should be established. This is generally in form of long and short sirens and flashing red lights at appropriate locations.
b) Emergency Shut-down There are number of facilities which can be provided to help deal with hazardous conditions, when a tank is in fire. Few suggested steps to control an emergency are:
Stop feed;
Dilute contents;
Remove heat;
Transfer contents.
Whether a given method is appropriate depends on the particular situation. Cessation of agitation may be the best action in some instances but may not be so in others. Stopping of the feed may require the provision of bypass arrangements. Methods for removing additional heat include removal through the normal cooling arrangements or use of an emergency cooling system.
The instructions from ECC and site controller should be followed. c) Evacuation of Personnel The personnel working in the storage and other area in the vicinity are those at higher risk from an emergency situation, and they should be made aware of the assembly points. The assembly points and approach to the assembly points should be clearly marked. In the event of an emergency, unconnected personnel have to escape to assembly point. Occupants/workers have to follow the emergency shutdown procedures and thereafter escape to assembly points. If necessary, rescue teams can be used to evacuate persons.
d) All Clear Signal At the end of an emergency, after discussing with Incident Controllers and Emergency coordinators, the Site Controller will declare an all clear signal.
Co-ordination with Local Authorities Keeping in view the nature of the emergency, two levels of co-ordination are proposed. In case of an On Site Emergency, resources within the building would be mobilized and in the event extreme emergency local authorities help should be sought.
In the event of an emergency developing into an offsite emergency, local authority and District emergency Authority (normally the Collector) would be appraised and under his supervision, the Off Site Disaster Management Plant would be exercised. For this purpose, the facilities that are available locally, i.e. medical, transport, personnel, accommodation, voluntary organizations etc. would be mustered. Necessary rehearsals and training in the form of mock drills should be organized.
20.7 Off-Site Emergency Preparedness Plan (OEPP) Off-site emergency management plan follows the on-site emergency plan. When the consequences of an emergency situation go beyond the plant boundaries, it becomes an off-site emergency. Key feature of a good off-site emergency plan is flexibility in its application to emergencies other than those specifically included in the formation of the plan.
The roles of the various parties who will be involved in the implementation of an off-site plan are described further. Depending on local arrangements, the responsibility for the off-site plan should either rest with the building management or, with the local authority. Either way, the plan should identify an emergency co-coordinating officer, who would take the overall command of the off-site activities. As with the on-site plan, an emergency control center should be set-up within which the emergency coordinating officer can operate.
Following condition can constitute an off-site emergency.
Off-site emergency is essentially the responsibility of the public administration (under EPA). However, the building management should provide the public administration with technical information on flammable materials released from the building in relation to the nature, quantum and probable consequences on the neighboring population (Schedule –12 of EPA act)
Aspects Proposed To Be Considered For the Off-Site EPP The main aspects which should be included in the emergency plan are:
Aspects Particulars Remarks Organization Details of command structure, warning systems, Site Controller implementation procedures, emergency control centers Name : Designation: Names and appointments of incident controller, site main Contact: controller, their deputies and other key personnel. Incident Controller Name: Designation: Contact:
Aspects Particulars Remarks Communications Identification of personnel involved, communication center, Site Controller call signs, network, lists of telephone numbers. Emergency coordinator Name: Designation: Contact: Specialized Details of specialist bodies, firms and people who may be knowledge contacted in the event of an emergency e.g. those with specialized knowledge, laboratories. Voluntary organizations Details of organizers, telephone numbers, resources etc.
Chemical information Details of the hazardous substances stored at site with a The MSDS of all the fuels used in the summary of the risk associated with them. building should be maintained at site be accessible to all. Meteorological information Arrangements for obtaining details of weather conditions Wind Socks prevailing at the time of an emergency and subsequent whether IMD station forecasts. Humanitarian arrangements Transport, evacuation centers, emergency feeding treatment of Local agencies the injured, first aid, ambulances, and temporary mortuaries. Temples Public information Arrangements for Site Controller a] dealing with the media /press Name : b] Informing relatives, etc. Designation: Contact: Assessment Arrangements for : Site Controller (a) collecting information on the causes of an emergency; (b) Reviewing the efficiency and effectiveness of all aspects of the emergency plan. Demographic information Neighboring population From DIC Other nearby industries Type of housing Livestock details
Role of the Emergency Coordinating Officer The various emergency services should be coordinated by an emergency coordinating officer (ECO), who will be designated by the district collector. The ECO should liaise closely with the site controller. Again depending on local arrangements, for very severe incidents with major or prolonged off-site consequences, the external control should be passed on to a senior local authority administrator or even an administrator appointed by the central or state government.
Role of the Local Authority It would be the responsibility of the local authorities to prepare the off-site emergency plan. The emergency planning officer (EPO) should carry out his duty in preparing for a whole range of different emergencies within his authority area. The EPO should closely work with plant personnel to obtain the information, prepare the emergency plan and continually update it.
It will be the responsibility of the EPO to ensure that all those organizations which will be involved with the offsite emergency are aware of their role and are able to accept, it by having for example, sufficient staff and appropriate equipment to take care of their assigned responsibilities. Rehearsals of the off-site plans should be organized by the EPO.
Role of Police Formal duties of the police during an emergency include protecting life and property and controlling traffic movements.
Their functions should include controlling bystanders, evacuating the public, identifying the dead and dealing with casualties, and informing the relatives of death or injury.
Role of Fire Authorities The control of a fire should normally be the responsibility of the senior fire brigade officer who would take over responsibility from the site / incident controller on arrival at the site. The senior fire brigade officer should also have a similar responsibility for other events, such as explosions
and toxic release. Fire authorities in the region should be appraised about the location of the storage of flammable materials, water and foam supply points, and fire-fighting equipment. They should be involved in on-site emergency rehearsals both as participants and, on occasion, as observers of exercises involving only site personnel.
Role of Health Authorities Health authorities, including doctors, surgeons, hospitals, ambulances, and so on, should have a vital part to play following a major accident, and they should form an integral part of the emergency plan.
For major fires, injuries would be the result of the effects of thermal radiation to a varying degree, and the knowledge and experience to handle this in all but extreme cases may generally be available in most hospitals. For major toxic releases, the effects vary according to the chemical in question, and the health authorities should be appraised about the likely toxic releases from the plant. This will enable them in dealing with the aftermath of a toxic release, with treatment appropriate to such casualties.
Major off-site incidents are likely to require medical equipment and facilities additional to those available locally, assistance of neighboring authorities should be available in the event of an emergency.
Role of Government Safety Authority The factory inspectorate of the region would want to satisfy themselves, that the organization responsible for producing the off-site plan has made adequate arrangements for handling emergencies of all types including major emergencies. They may wish to see well documented procedures and evidence of exercise undertaken to test the plan.
In the event of an accident, local arrangements regarding the role of the factory inspector will apply. These may vary from keeping a watching brief to a close involvement in advising operation In case of release of toxic gases the factory inspectorate may be the only external agency with equipment and resources to carry out the tests.
20.8 Occupational Health and Safety Building where multifarious activities are involved during construction, erection, occupancy and maintenance, the men, materials and machines are the basic inputs. Along with the boon, it generally brings several problems like occupational health and safety.
The building planner, therefore, has to properly plan and take the steps to minimize the impacts of industrialization and to ensure appropriate occupational health, safety including fire plans. All these activities again may be classified under construction and erection, and operation and maintenance. The proposed safety plan is given below:
Occupational Health Occupational health needs attention both during construction and erection and operation and maintenance phases. However, the problem varies both in magnitude and variety in the above phases.
