CHAPTER :2 RISK ASSESSMENT PROCESS RISK ASSESSMENT Identification analysis and assessment of hazard and risk are very useful in providing information to risk management. It provides basis for what should be type and capacity of its on-site and off-site emergency plan also what types of safety measures are required. Risk and consequence analysis is carried out considering storage and handling of various hazardous raw materials, intermediates and product as well as manufacturing process. This section details the risk assessment process performed during this effort. The process is divided into pre-assessment, assessment, and post assessment phases. PHASE I – PRE-ASSESSMENT Step 1: Define the Nature of the Risk Assessment This initial risk assessment provides an independent review to help Centers for Disease Control and Prevention (CDC) determine the appropriate level of security required for the system to support the development of a System Security Plan for intermediate chemical resin plant. The risk assessment is based on interviews, documentation and, as necessary, some automated technical review. Step 2: Data Collection The data collection phase included identifying and interviewing key personnel within the organization and conducting document reviews. Interviews focused on the operating environment. Document reviews provided the risk assessment team with the basis on which to evaluate compliance with policy and procedure. Prepared By M/s. Bhagwati Enviro Care Pvt Ltd. 243 Risk Assessment Study Report of Tridev Industries at Plot No.D-2/CH/134, GIDC Estate, Dahej, Ta – Vagra, Dist –Bharuch, Gujarat. Step 3: Templates The following templates were used by the risk assessment team and are included in the appendices: • Security Baseline Worksheet: Completed by the analysts using information extracted from questionnaires and interviews. • Risk Calculation Worksheet: Converts the raw vulnerabilities into risks based on the following methodology: • Risk Mitigation Worksheet: Lists the risks and the associated recommended controls to mitigate these risks for the Business Steward to review. PHASE II – ASSESSMENT Step 1: Document Review The assessment phase began with the review of documents provided by the members of the various Resin manufacturing system team. Detailed interviews with members of the CDC Resins manufacturing system team allowed completion of the system questionnaire and identification of specific threats inadequately identified in the Enterprise Threat Statement. Step 2: System Characterization In this step, the analyst defined the boundaries of the IT system, along with the resources that constitute the system, its connectivity, and any other elements necessary to describe the system. Dependencies were clarified. Sensitivity of the system and data was discussed in the final section of the characterization. Step 3: Threat Identification Through the interview process, it also identified “most likely” system and location-specific threats. Prepared By M/s.

Step 4: Vulnerability Identification In this step, the risk assessment team developed a list of system vulnerabilities (flaws or weaknesses) that could be exploited by the potential threat vectors. Step 5: Risk Determination (Calculation/Valuation) In this step, the risk assessment team determined the degree of risk to the system. In some cases, a series of vulnerabilities combined to create the risk. In other cases, a single vulnerability created the risk. The determination of risk for a particular threat source was expressed as a function of the following: • • • • • Likelihood Determination: The following governing factors were considered when calculating the likelihood of the probability that a potential vulnerability might be exploited in the context of the associated threat environment: Threat source motivation and capability Nature of the vulnerability Existence and effectiveness of current controls The following table defines the likelihood determinations. Table1. Likelihood Definition Level Likelihood Definition High The threat source is highly motivated and sufficiently capable, and controls to prevent the vulnerability from being exercised are ineffective. Moderate The threat source is motivated and capable, but controls are place that may impede successful exercise of the vulnerability. Low The threat source lacks motivation or capability, or controls are in place to prevent, or at least significantly impede, the vulnerability from being exercised. Prepared By M/s. Bhagwati Enviro Care Pvt Ltd. 245 Risk Assessment Study Report of Tridev Industries at Plot No.D-2/CH/134, GIDC Estate, Dahej, Ta – Vagra, Dist –Bharuch, Gujarat. Impact Analysis: The next major step in measuring level of risk was to determine the adverse impact resulting from successful exploitation of vulnerability. The adverse impact of a security event can be described in terms of loss or degradation of any, or a combination of any, of the following three security goals: • Loss of Confidentiality – Impact of unauthorized disclosure of sensitive information (e.g., Privacy Act). • Loss of Integrity – Impact if system or data integrity is lost by unauthorized changes to the data or system. • Loss of Availability – Impact to system functionality and operational effectiveness. Table 2. Impact Definition Magnitude of Impact High Impact Definition Exercise of the vulnerability (1) may result in the highly costly loss of major tangible assets or resources; (2) may significantly violate, harm, or impede an organization’s mission, reputation, or interest; or (3) may result in human death or serious injury. Moderate Exercise of the vulnerability (1) may result in the costly loss of tangible assets or resources; (2) may violate, harm or impeded an organization’s mission, reputation, or interest; or (3) may result in human injury. Low Exercise of the vulnerability (1) may result tangible assets or resources; (2) may organization’s mission, reputation, or interest. in the loss of some noticeably affect an Prepared By M/s. Bhagwati Enviro Care Pvt Ltd. 246 Risk Assessment Study Report of Tridev Industries at Plot No.D-2/CH/134, GIDC Estate, Dahej, Ta – Vagra, Dist –Bharuch, Gujarat. • Risk Determination: The following were used to assess the level of risk to the IT system: • • • The likelihood of a given threat source’s attempting to exercise a given vulnerability. The magnitude of the impact should a threat-source successfully exercise the vulnerability. The adequacy of planned or existing security controls for reducing or eliminating risk. The following table provides a definition for the risk levels. These levels represent the degree or level of risk to which an IT system, facility, or procedure might be exposed if a given vulnerability were exercised. Table 3. Risk Level Definition Magnitude of Impact Risk Level Definition High There is a strong need for corrective measures. An existing system may continue to operate, but a corrective action plan must be put in place as soon as possible. Moderate Corrective actions are needed and a plan must be developed to incorporate these actions within a reasonable period of time. Low The system’s Authorizing Official must determine whether corrective actions are still required or decide to accept the risk. Step 6: Risk Mitigation Recommendations: During this step of the process, controls that could mitigate or eliminate the identified risks, as appropriate to the organization’s operations, were provided. The goal of the recommended controls is to reduce the level of risk to the IT system and its data to an acceptable level. The risk assessment team considered the following factors when recommending controls and alternative solutions to minimize or eliminate identified risks: • • • • • • Sensitivity of the data and the system Effectiveness of recommended options Legislation and regulations Organizational policy Operational impact Safety and reliability Prepared By M/s.

CHAPTER: 10 HAZARDS IDENTIFICATION, MAJOR HAZARDS & DAMAGE CRITERIA HAZARDS IDENTIFICATION: Hazard is defined as a chemical or physical condition that has a potential of causing damage to the people, property or the environment. Hazard identification is the first step in the risk analysis and entails the process of collecting information on: • • • • The types and quantities of hazardous substances stored and handled, The location of storage tanks & other facilities, potential hazards associated with the spillage and release of hazardous Chemicals. Hazard is the associated term with material, which is a measure or the likely hood of the damage to human working with, or studying the material in question. The potential hazard and major risks associated with the plant will be identified using Hazard & operability study (HAZOP). MAJOR HAZARDS: A brief description of the following hazards generally encountered in handling hazardous chemicals is given in the section. • • • • • • • Pool Evaporation Vapor Cloud Explosion Vapor Cloud Dispersion Pool Fire Jet Fire BLEVE Toxic Release Prepared By M/s. Bhagwati Enviro Care Pvt Ltd. 294 Risk Assessment Study Report of Tridev Industries at Plot No.D-2/CH/134, GIDC Estate, Dahej, Ta – Vagra, Dist –Bharuch, Gujarat. Pool Evaporation If the fluid, which escapes from containment, is a liquid, then vaporization must occur before a vapor cloud is formed. The rate at which vaporization takes place determines the formation of such a vapor clouds. Vaporization scenarios Vaporization can occur when there is a leak in any of the following situations: a) A liquid at atmospheric temperature and pressure. b) A liquid under pressure and above normal boiling point. The rates of vaporization of the liquid are different for each of the two cases. In the case • • The liquid after spillage is approximately at equilibrium and evaporates relativity slowly. In the case, the liquid flashes off when released, and the liquid remaining then undergoes slow evaporation. (I) Evaporation of a liquid at atmospheric temperature and pressure. Evaporation from a pool of liquid is essentially a mass transfer process that depends on the vapor pressure of the liquid, wind velocity across the surface of the pool and ambient weather condition. A spillage of this kind constitutes a steady continuous source of vapor. Unless the rate of evaporation due to the combination of vapor pressure and wind velocity is high enough, it is usually assumed that the heat transfer from the air and the ground is sufficient to provide the latent heat of vaporization. (II) Evaporation of a liquid under pressure and above normal boiling point When a pressurized liquid is released from containment a portion flashes off. This heat is obtained by cooling the remaining liquid to its boiling point thus reaching a state of equilibrium from the high in equilibrium prevalent immediately on loss of containment. In practice, it frequently happens that there is a significant amount of spray formation caused by the sudden release of pressure and the violent boiling of liquid. This spray vaporizes rapidly by taking heat for vaporization from air. This spray liquid formation is assumed to equal to the gas fraction generated by flash. The proportion of liquid airborne is thus considerably high. Following flashing, the residual liquid is at its boiling point. Vaporization then continuous by gaining heat from surrounding as an essentially heat or mass transfer limited process. This secondary stage of rate limited vaporization is usually relatively less Prepared By M/s.

Vapor Cloud dispersion Following a continuous leak and formation of gas cloud, if cloud does not ignite it undergoes atmospheric dispersion in accordance with the prevalent wind direction, speed and stability category. The objective of carrying out analysis of cloud dispersion is two fold. First, it provides the distance (from the leak) at which the concentration of flammable material falls below the lower flammability limit (LEL). Second it provides the concentration of the toxic substance to which people may be exposed for short time, at varying distance (from the leak). Vapor cloud Explosion Release of energy in a rapid and uncontrolled manner gives rise to explosion. Identified locations having explosion hazards shall in tank farm and storage area (warehouse). Extra care shall be taken by providing rupture disc, Pressure release valve, and temperature controller. In addition to that Fire and explosion hazard will identified as catastrophic failure of storage tanks in solvent storage yard. Explosion is a sudden and violent- release of energy which may be in the form of physical energy or chemical energy. In case where a major leak continues from some time without ignition a substantial mass of the gas from a vapor of cloud which on finding a source of ignition may result in an vapor cloud explosion (VCE) before a cloud is diluted to the concentration below the lower explosion limit in air. The explosion will cause overpressure resulting in to damage to the surrounding area. Pool fire Since the Stone Age term 'fire' is associated with fear. It is very dangerous if occurs in uncontrolled manner. It should be clearly understood that when a liquid is used having flash point below the normal ambient temperature, it could, in suitable circumstances, liberate a sufficient quantity of vapour to give rise to flammable mixtures with air. Following an accidental release, chemicals will form either a confined pool within the bund area or an unconfined pool. Should the vapor above the pool ignite, the liquid will burn as a pool fire. The pool fire will result in thermal radiation. It cloud also damage all the storage tanks within the confined area of the dyke. In the present study, impact distances for various scenarios have been calculated. Prepared By M/s. Bhagwati Enviro Care Pvt Ltd. 296 Risk Assessment Study Report of Tridev Industries at Plot No.D-2/CH/134, GIDC Estate, Dahej, Ta – Vagra, Dist –Bharuch, Gujarat. Jet fire After a minor or major loss of containment following hardware failure, chemicals which are stored under high pressure would escape as liquid/ gas spray or jet which undergoes flashing evaporation and forms a dense flammable gas could in the air. The cloud, which initially moves forward in the spatial direction of the spray till the kinetic energy, is lost and gravity slumping of cloud occurs if the gas is heavier than the air. Should the flammable jet ignite very soon after development of leak? A jet fire will commence. The jet fire could damage the neighboring tanks by direct flame impingement. It would also cause thermal radiation in the surrounding area. Fire Ball / BLEVE Any fire in the vicinity of storage tank containing a liquefied gas may cause Boiling Expanding Vapor Explosion (BLEVE). Due to simultaneous increase of pressure as well as weakening of the material of the vessel because of a fire in the vicinity the tank. It may fail resulting in release of the entire inventory suddenly and result in a BLEVE and fireball. BLEVE results in serious thermal radiation to the plant equipment and surroundings. Damage may also result to the debris of the shattered vessel being thrown about. The major hazards in the M/s. Tridev Industries. are described below. • Toxic hazard due to leakage of hazardous chemicals. • Fire hazard due to leakage of flammable chemicals. • Electrical hazards due to the electrical major equipment/ machinery, operations, welding, motors, heavy lift devices, cabling, human intervention (short circuit possibility), maintenance work (due to machinery breakdown etc.), plant lighting related electrical hazards. • Possibility of human injury due to working with mechanical machines, manual handling etc. • Possibility of injury during chemicals handled, during operations and due to intoxication. • Major dropped objects hazard due to large number of physical handling steps / operations involved with crane/ overhead lifting/ hoisting equipment. • Fires in any part of the plant working areas – there is a possibility of rapid escalation if it is not brought under control quickly.

Toxic hazards Toxic substances affect in three ways by ingestion, absorption & inhalation. Adequate provision of safety along with personal protective equipment will be made, breathing apparatus and emergency kit shall be provided at various locations of the installation. Corrosion hazards Corrosion is a chemical reaction-taking place at the surface of metal. Corrosive chemicals have their typical hazard when it comes in contact with human tissues. Most corrosive substances will produce chemical burns, while certain chemical produce deep ulceration. Other has detailing effect on skin and may cause dermatitis. This has also adverse effects on weakening the strength of material in contact. M/s. Tridev Industries shall take due care to overcome the hazard. The complete structure of the manufacturing area shall be painted with special type of anticorrosive paint. Good quality materials will be used for transferring corrosives. Regular thickness testing of equipment, pipelines etc. shall carry out to have the exact picture of effect of corrosion. Biological hazards Effluent treatment process involves the biological activities so biological hazard’s can not be eliminated. The way of biological hazards is by hand to mouth contact during eating, drinking or by wiping the face with contaminated hands or gloves or by licking splashes from the skin or by breathing them in, as dust, aerosol or mist. The major source of biological hazard on site is biological sludge drying bed, filter press, biological storage sump etc. Practically, complete elimination of biological hazard can not be possible but it will be reduce by adopting the safe practice guards.

DAMAGE CRITERIA: Damage estimates due to thermal radiations and overpressure have been arrived at by taking in to consideration the published literature on the subject. The consequences can then be visualized by the superimposing the damage effects zones on the proposed plan site and identifying the elements within the project site as well as in the neighboring environment, which might be adversely affected, should one or more hazards materialize in real life. In consequence analysis, use is made of a number of calculation models to estimate the physical effects of an accident (spill of hazardous material) and to predict the damage (lethality, injury, material destruction) of the effects. The calculations can roughly be divided in three major groups: a) Determination of the source strength parameters; b) Determination of the consequential effects; c) Determination of the damage or damage distances. The basic physical effect models consist of the following. Source strength parameters * Calculation of the outflow of liquid, vapour or gas out of a vessel or a pipe, in case of rupture. Also two-phase outflow can be calculated. * Calculation, in case of liquid outflow, of the instantaneous flash evaporation and of the dimensions of the remaining liquid pool. * Calculation of the evaporation rate, as a function of volatility of the material, pool dimensions and wind velocity. * Source strength equals pump capacities, etc. in some cases. Prepared By M/s. Bhagwati Enviro Care Pvt Ltd. 299 Risk Assessment Study Report of Tridev Industries at Plot No.D-2/CH/134, GIDC Estate, Dahej, Ta – Vagra, Dist –Bharuch, Gujarat. Consequential effects * Dispersion of gaseous material in the atmosphere as a function of source strength, relative density of the gas, weather conditions and topographical situation of the surrounding area. * Intensity of heat radiation [in kW/ m2] due to a fire or a BLEVE, as a function of the distance to the source. * Energy of vapour cloud explosions [in N/m2], as a function of the distance to the distance of the exploding cloud. * Concentration of gaseous material in the atmosphere, due to the dispersion of evaporated chemical. The latter can be either explosive or toxic. It may be obvious, that the types of models that must be used in a specific risk study strongly depend upon the type of material involved: - Gas, vapour, liquid, solid - Inflammable, explosive, toxic, toxic combustion products - Stored at high/low temperatures or pressure - Controlled outflow (pump capacity) or catastrophic failure? Selection of Damage Criteria The damage criteria give the relation between extent of the physical effects (exposure) and the percentage of the people that will be killed or injured due to those effects. The knowledge about these relations depends strongly on the nature of the exposure. For instance, much more is known about the damage caused by heat radiation, than about the damage due to toxic exposure, and for these toxic effects, the knowledge differs strongly between different materials. In Consequence Analysis studies, in principle three types of exposure to hazardous effects are distinguished: Prepared By M/s.

Heat radiation, from a jet, pool fire, a flash fire or a BLEVE. 2. Explosion 3. Toxic effects, from toxic materials or toxic combustion products. In the next three paragraphs, the chosen damage criteria are given and explained. Heat Radiation The consequence caused by exposure to heat radiation is a function of: 2 • The radiation energy onto the human body [kW/m ]; • The exposure duration [sec]; • The protection of the skin tissue (clothed or naked body). • The limits for 1% of the exposed people to be killed due to heat radiation, and for second-degree burns are given in the table herein: Damages to Human Life Due to Heat Radiation Exposure Radiation Duration 1% for Radiation lethality 2nd (kW/m2) for Radiation degree first for degree burns, (kW/m2) burns (kW/m2) 10 Sec 21.2 16 12.5 30 Sec 9.3 7.0 4.0 Since in practical situations, only the own employees will be exposed to heat radiation in case of a fire, it is reasonable to assume the protection by clothing. It can be assumed that people would be able to find a cover or a shield against thermal radiation in 10 sec. time. Furthermore, 100% lethality may be assumed for all people suffering Prepared By M/s. Bhagwati Enviro Care Pvt Ltd. 301 Risk Assessment Study Report of Tridev Industries at Plot No.D-2/CH/134, GIDC Estate, Dahej, Ta – Vagra, Dist –Bharuch, Gujarat. from direct contact with flames, such as the pool fire, a flash fire or a jet flame. The effects due to relatively lesser incident radiation intensity are given below.

Bhagwati Enviro Care Pvt Ltd. 302 Risk Assessment Study Report of Tridev Industries at Plot No.D-2/CH/134, GIDC Estate, Dahej, Ta – Vagra, Dist –Bharuch, Gujarat. Explosion In case of vapour cloud explosion, two physical effects may occur: * a flash fire over the whole length of the explosive gas cloud; * a blast wave, with typical peak overpressures circular around ignition source. As explained above, 100% lethality is assumed for all people who are present within the cloud proper. For the blast wave, the lethality criterion is based on: * A peak overpressure of 0.1 bar will cause serious damage to 10% of the housing/structures. * Falling fragments will kill one of each eight persons in the destroyed buildings. The following damage criteria may be distinguished with respect to the peak overpressures resulting from a blast wave: FATAL RADIATION EXPOSURE LEVELS: RADIATION FATALITY LEVEL kW/m2 1% 50% 99% EXPOSURE IN SECONDS 4.0 150 370 930 12.5 30 80 200 37.5 8 20 50 Prepared By M/s.

Bhagwati Enviro Care Pvt Ltd. 304 Risk Assessment Study Report of Tridev Industries at Plot No.D-2/CH/134, GIDC Estate, Dahej, Ta – Vagra, Dist –Bharuch, Gujarat. From this it may be concluded that p = 0.17 E+5 pa corresponds approximately with 1% lethality. Furthermore it is assumed that everyone inside an area in which the peak overpressure is greater than 0.17 E+5 pa will be wounded by mechanical damage. For the gas cloud explosion this will be inside a circle with the ignition source as its centre. Intoxication The consequences from inhalation of a toxic vapour/gas are determined by the toxic dose. This dose D is basically determined by: - Concentration of the vapour in air; - Exposure duration. Furthermore, of course, the breathing rates of the victim, as well as the specific toxic mechanism unto the metabolism play an important role. n The dose is defined as D = C .t, with: C = concentration of the toxic vapour, in [ppm] or [mg/m3]; t = exposure duration, in [sec] or [min]; n = exponent, mostly > 1.0; this exponent takes into account the fact that a high concentration over a short period results in more serious injury than a low concentration over a relatively longer period of exposure. The value of n should be greater than zero but less than 5. The given definition for D only holds if the concentration is more or less constant over the exposure time; this may be the case for a (semi) continuous source. In case of an instantaneous source, the concentration varies with time; the dose D must be calculated with an integral equation: Prepared By M/s. Bhagwati Enviro Care Pvt Ltd. 305 Risk Assessment Study Report of Tridev Industries at Plot No.D-2/CH/134, GIDC Estate, Dahej, Ta – Vagra, Dist –Bharuch, Gujarat. D = ∫ Cn.dt For a number of toxic materials, so-called Vulnerability Models (V.M.) have been developed. The general equation for a V.M. (probit function) is: Pr = a + b.ln (Cn.t), with Pr = probit number, being a representation of the percentage of people suffering a certain kind of damage, for instance lethality Pr = 2.67 means 1% of the population; Pr = 5.00 means 50% of the population; a and b material dependent numbers; Cn.t = dose D, as explained above. The values for a and b are mostly derived from experiments with animals; occasionally, however, also human toxicity factors have been derived from accidents in past. In case only animal experiments are available, the inhalation experiments with rats seem to be best applicable for predicting the damage to people from acute intoxication. Although much research in this field have been done over the past decades, only for a limited number of toxic materials consequence models have been developed. Often only quite scarce information is available to predict the damage from an acute toxic exposition. Data transformation from oral intoxication data to inhalation toxicity criteria is sometimes necessary. Generally, in safety evaluations pessimistic assumptions are applied in these transformation calculations. The calculated damage (distance) may be regarded as a maximum. For the purposes of a response to a major incident, the IDLH value level has been chosen for the ‘wounded‘ criteria. This type of injury will require medical attention. Prepared By M/s.

Toxic Effects: The effect of exposure to a toxic substance depends upon the duration of exposure and the concentration of the toxic substance. Short-term exposures to high concentration give Acute Effects while long term exposures to low concentrations result in Chronic Effects. Only Acute Effects are considered under hazard analysis, since they are likely credible scenarios. These effects are: a) Irritation (respiratory system skin, eyes) b) Narcosis (nervous system) c) Asphyxiation (oxygen deficiency) d) System damage (blood organs) Following are some of the common terms used to express toxicity of materials: TLV: Threshold Limit Value – is the permitted level of exposure for a given period on a weighted average basis (usually 8 hrs.for 5 days in a week). STEL: it is permitted Short Time Exposure Limit usually for a 15-minute exposure. IDLH: Immediately Dangerous To Life & Health LCLo: Lethal Concentration Low TCLo: Toxic Concentration Low Prepared By M/s.

CHAPTER: 11 CONSEQUENCE ANALYSIS & RISK ANALYSIS CONSEQUENCE ANALYSIS In a plant handling hazardous chemicals, the main hazard arises due to storage, handling & use of these chemicals. If these chemicals are released into the atmosphere, they may cause damage due to resulting fires or vapour clouds. Blast Overpressures depend upon the reactivity class of material between two explosive limits. Operating Parameters Potential vapour release for the same material depends significantly on the operating conditions. Especially for any liquefied gas, the operating conditions are very critical to assess the damage potential. If we take up an example of ammonia, if it is stored at ambient temperature, say about 28oC, and then the vapour release potential of the inventory is much higher as compared to the case if it is stored at 0oC. Inventory Inventory Analysis is commonly used in understanding the relative hazards and short listing of release scenarios. Inventory plays an important role in regard to the potential hazard. Larger the inventory of a vessel or a system, larger the quantity of potential release. The potential vapour release (source strength) depends upon the quantity of liquid release, the properties of the materials and the operating conditions (pressure, temperature). If all these influencing parameters are combined into a matrix and vapour source strength estimated for each release case, a ranking should become a credible exercise. Prepared By M/s. Bhagwati Enviro Care Pvt Ltd. 308 Risk Assessment Study Report of Tridev Industries at Plot No.D-2/CH/134, GIDC Estate, Dahej, Ta – Vagra, Dist –Bharuch, Gujarat. Loss of Containment Plant inventory can get discharged to Environment due to Loss of Containment. Certain features of materials to be handled at the plant need to the clearly understood to firstly list out all significant release cases and then to short list release scenarios for a detailed examination. Liquid release can be either instantaneous or continuous. Failure of a vessel leading to an instantaneous outflow assumes the sudden appearance of such a major crack that practically all of the contents above the crack shall be released in a very short time. The more likely event is the case of liquid release from a hole in a pipe connected to the vessel. The flow rate is depending on the size of the hole as well as on the pressure, which was present, in front of the hole, prior to the accident. Such pressure is basically dependent on the pressure in the vessel. The vaporisation of released liquid depends on the vapour pressure and weather conditions. Such consideration and others have been kept in mind both during the initial listing as well as during the short listing procedure. In the study, Maximum Credible Loss accident methodology is to be used, therefore, the largest potential hazard inventories have been considered for consequence estimation. MAXIMUM CREDIBLE LOSS ACCIDENT SCENARIOS A Maximum Credible Accident (MCA) can be characterised as the worst credible accident. In other words: an accident in an activity, resulting in the maximum consequence distance that is still believed to be possible. A MCA‐analysis does not include a quantification of the probability of occurrence of the accident. Another aspect, in which the pessimistic approach of MCA studies appears, is the atmospheric condition that is used for dispersion calculations. As per the reference of the study, weather conditions having an average wind speed of 2.18 m/s have been chosen. The Maximum Credible Loss (MCL) scenarios have been developed for the Facility. The MCL cases considered, attempt to include the worst “Credible” incidents‐ what constitutes a credible incident is always subjective. Nevertheless, guidelines have evolved over the years and based Prepared By M/s. Bhagwati Enviro Care Pvt Ltd. 309 Risk Assessment Study Report of Tridev Industries at Plot No.D-2/CH/134, GIDC Estate, Dahej, Ta – Vagra, Dist –Bharuch, Gujarat. on basic engineering judgement, the cases have been found to be credible and modelling for assessing vulnerability zones is prepared accordingly. Only catastrophic cases have been considered and not partial or small failures (as is the case in Quantitative Risk Assessment where contributions from low frequency ‐ high outcome effect as well as high frequency ‐ low outcome events are distinguished). The objective of the study is emergency planning, hence only holistic & conservative assumptions are used for obvious reasons. Hence though the outcomes may look pessimistic, the planning for emergency concept should be borne in mind whilst interpreting the results. CONSEQUENCE ANALYSIS CALCULATIONS The Consequence Analysis has been done for selected scenarios. This has been done for weather conditions having wind speed 2.18 m/s. In Consequence Analysis, geographical location of the source of potential release plays an important role. Consideration of a large number of scenarios in the same geographical location serves little purpose if the dominant scenario has been identified and duly considered. 6.7.3.1 SOFTWARE USED FOR CALCULATIONS Aloha 5.1.1.2 is the most comprehensive software available for performing Process Hazard Analysis (PHA), Quantitative Risk Assessment (QRA) and Financial Risk Analysis (FRA).
