ADDITIONAL STUDIES 7.1 Risk Assessment 7.1.1 Overview of Project M/s. Saurastra Chemicals Division of Nirma Ltdis located at Birlasager, Village-Chhaya, Ta.& Dist.-Porbandar. The site is situated at21°37’39.19”N latitude and 69°37’34.06” E longitude. Unit has a total land area of 518974 m2. Plant layout of existing manufacturing facility is given in Chapter 2 of this report.The same layout space allocated for proposed expansion of Soda Ash, Sodium Carbonate and Co generation Power Plant. 7.1.2 Objective and Scope The main objective of risk assessment study is to propose an approach to carry out risk analysis and management of industrial prototype hazard. The risk assessment essentially includes hazards identification, consequence analysis, risk assessment/evaluation and risk mitigation. For chemical industries, risk assessment is used for determining the risk associated with use, handling, transportation and storage of chemicals and other hazardous substances. Quantitative Risk Assessments (QRAs) are done if dangerous substances are thought to be present at a location (e.g. industrial sites and transportation routes) in amounts that can endanger the environment. Scope of the Study;

Hazard Identification - Identifying sources of accidents involving release of hazardous material in the atmosphere and the various ways (that is scenarios) they could occur

Consequence Assessment - Estimating the probable zone of impact of accidents as well as the scale and/or probability of damages with respect to human beings and plant equipment and other structuresusing relevant models like ALOHA

Accident Frequency Assessment - Computation of the average likelihood of accidents Risk Estimation - Combining accident consequence and frequency to obtain risk

distribution within and beyond a process plant 7.1.3 Risk Assessment Methodology

Information on Location, Layout, Process Parameters Hazard Identification Select Most Credible Scenario which can culminate into an accident out of several major

and minor. Select Worst Case Scenario which has the highest potential to cause an accident of

maximum damage Estimate Consequences: in the plant in the form of fire, explosion and toxic effects

7.2 Hazard Identification and Risk Assessment (HIRA) The hazard identification and risk assessment is used to identify possible accidents and

estimate their frequency and consequences. While identifying hazards only those areas of plants having potential risk are used further for risk analysis. Hazard is considered as characteristic of system/plant/process that presents potential of causing harm to people, property and the environment. Hence, all the components of a system/plant/process are thoroughly examined to assess their potential for initiating or propagating an unplanned event/sequence of events, which can be termed as an accident. 7.2.1 Hazard Identification Methods Hazard identification method usedfor the proposed expansion project is given below.

Identification of major hazardous units based on Manufacture, Storage and Import of Hazardous Chemicals Rules, 1989 of Government of India (as amended in 2000); Hazard Indices: Identification of hazardous units and segments of plants and storage units based on relative ranking technique.

7.2.2 Identification of Hazardous Chemicals used within Premises Following chemicals to be stored and utilized within the premises falls under Manufacture, Storage and Import of Hazardous Chemicals Rules, 1989 (as amended in 2000). List of Hazardous Chemicals is given below. Amongst the below described raw materials and products, some are the hazardous chemicals as per the MSIHC Rules, 2000.

7.2.4 Credible Accident Sources/ Worst Case Scenarios

Maximum Credible Accident (MCA) scenario indicates most believable, reasonable, likely or possible accident scenario and damage distance based on it. MCA scenario takes into account the effect of existing control measures also. It considers the malfunctioning of the control system, opening of safety valve/failure of safety valve, leakages from flange joint, pipe line etc. and failing of some safety devise.

Worst-case scenario (rarely possible) is defined as the release of the largest quantity of a regulated substance from a single vessel or process line failure that results in the greatest distance to an end point, e.g. catastrophic failure. It considers the failure of all control systems and release of the whole mass resulting in maximum damage.

Based on the storage and properties of the chemicals at the unit, the some typical scenarios relevant for MCA analysis is given in the following Table 7.7.

7.3 Consequence Modeling Hazardous incidents start with a discharge of a flammable or toxic material from its normal containment. Discharge can take place from a crack or fracture of process vessels or pipe work, an open valve or from an emergency vent. The release may be in the form of gas, liquid, or two phase flashing of gas-liquid. 7.4 Damage Criteria The storage and unloading at the storage facility may lead to fire and explosion hazards. The damage criteria due to an accidental release of any hydrocarbon arise from fire and explosion. 7.4.1 Fire Damage

Table 7.8 tabulates the damage effect on equipment and people due to thermal radiation intensity whereas; the effect of incident radiation intensity and exposure time on lethality is given in Table 7.9.

Annexure No 10 : Additional Studies 7.13

IDLH (Immediate Danger to Life or Health) is the maximum concentration from which escape is possible within 30 minutes without any escape-impairing symptoms or irreversible health effects. AEGL (Acute Exposure Guideline Levels) are exposure guidelines designed to helpresponders deal with emergencies involving chemical spills or other catastrophic eventswhere members of the general public are exposed to a hazardous airborne chemical. (Acute exposures are single, non-repetitive exposures that don't exceed 8 hours.) 7.4.4 Details of Model Used for Consequence Analysis

ALOHA provide output as amount of chemical discharged from the source as well as its concentration in air it takes into account different levels of concentrations for a specified chemical.

Software used for calculation is ALOHA (AREAL LOCATIONS OF HAZARDOUS ATMOSPHERES) which is a computer program designed especially for use by people responding to chemical accidents, as well as for emergency planning and training. ALOHA can predict the rates at which chemical vapors may escape into the atmosphere from broken gas pipes, leaking tanks and evaporating puddles. It can then predict how a hazardous gas cloud might disperse in the atmosphere after an accidental chemical release. ALOHA provides output as amount of chemical discharged from the source as well as its concentration in air it takes in to account different levels of concentrations for a specified chemical. Different concentration levels are given below:

AEGL 3:is the airborne concentration, expressed as parts per million (ppm) or milligrams per cubic meter (mg/m3), of substance above which it is predicted that the general population, including susceptible individuals, could experience life-threatening health effects or death. AEGL 2:is the airborne concentration (expressed as ppm or mg/m3) of a substance above which it is predicted that the general population, including susceptible individuals, could experience irreversible or other serious, long-lasting adverse health effects or an impaired ability to escape. AEGL 1:is the airborne concentration (expressed as ppm or mg/m3) of a substance above which it is predicted that the general population, including susceptible individuals, could experience notable discomfort, irritation, or certain asymptomatic no sensory effects. However, the effects are not disabling and are transient and reversible upon cessation of exposure. IDLH: The Immediately Dangerous to Life or Health (IDLH) level. A chemical's IDLH is an estimate of the maximum concentration in the air to which a healthy worker could be exposed without suffering permanent or escape-impairing health effects. Input data for ALOHA are as below: Weather Data:

Average Wind Speed: 5 m/sec & 1.5 m/sec Average Ambient Temperature: 40 °C, 22 °C Average Humidity: 25%, 68% Atmosphere Stability Class: D (windy day time), F (Extreme calm, night time)

All the threat zones in the unit are super imposed on Google image. Figure 7.1 &7.2 shows the map of vulnerable areas corresponding to different individual outcome cases. Figure 7.1 gives the location, where individual risk is found to be a maximum at locations within premises. A broadly acceptable level of individual risk as per the ALARP (AS LOW AS REASONABLY PRACTICABLE) concept of HSE, UK is 10-6/year.

7.6 Summary

It may be noted that in dispersion modeling, the wind direction and air temperature, atmospheric stability are found to be the deciding factors for the threat zones.

Offsite Emergency Preparedness Plan

Offsite emergency plan would follow the onsite emergency plan. When the consequences of an emergency situation go beyond the plant boundaries, it becomes an offsite emergency. As the off-site emergency plan is to be prepared by the Government, a Central Control Committee or Group shall be formed under the Chairmanship of the area head. For example, assume a district structure and District Collector (is the Chairman of the District Control Committee (DCC). Offsite emergency plan: -

In the manufacture of soda ash by solve process, unit has to use one and the only toxic as well as hazardous chemical, viz. ammonia, which is also sometimes explosive and flammable at very high temperature of 650 deg. C and the concentration in air to the true of 16 to 25 %, which is extremely rare. In view of the toxic mature of ammonia, it may affect the outside areas also, in situations, when there is sudden release of large quantities of the gas. The possibilities of the above situations, through very remote, warrant us to prepare an off-site emergency plan to immediately inform the populace likely to be affected, evacuate if necessary, to a safer place and to instruct them the safety measures, to safe- guard themselves. With the above in view, Unit has prepared an offsite emergency plan. Industry has designated site main controller, incident controller and deputy Incident controller as well, to lead the situation, guide and control all the arrangements and bring the disaster under control. It has arranged well-set communications system, procedure for identification of personnel, emergency action squad, emergency telephone list, and key personals, for various emergency duties. It also has fleet of vehicles for emergency movements/evacuation purposes and some special equipment for special purposes. For off-site emergency, Unit would take the help of outside authorities also. Meteorological in formations are also collected, to serve as guidelines e.g. for evacuation or moving to safer place. Press-public relations are arranged. Medical aid to victims will be arranged. Rehabilitations will be arranged when the situation is well within control and if is ascertained that there is no longer any danger. In case of fire or toxic gas release, the workers who find it first, will shout “Fire Fire” or “Gas Gas” as the case may be and run. Inform his Supervisor /any senior staff, who is seen first. who in turn will inform his high-ups, all the concerned persons and then with the help of essential workers, he will drive away all the fire by using appropriate portable fire extinguishers/try to close the valve of the gas leaking line, using proper respirators. If needed fire brigade will also be called in and pressed into service.
