RISK ASSESSMENT

1.2 RISK ASSESSMENT

1.1.1 Introduction Background As proposed project is only the associated and additional to the 7.0 MTPA modernization-cum-expansion project, i.e. the proposed project is a small component of a large project. The risk associated with the proposed project and the onsite and offsite emergency plan are covered and implemented in the 7.0 MTPA modernization-cum-expansion project and thus in this chapter the same is being described. General Industrial activities, which produce, treat, store and handle hazardous substances, have a high hazard potential endangering the safety of man and environment at work place and outside. Recognizing the need to control and minimize the risks posed by such activities, the Ministry of Environment, Forest and Climate Change have notified the “Manufacture Storage & Import of Hazardous Chemicals Rules” in the year 1989 and subsequently modified, inserted and added different clauses in the said rule to make it more stringent. For effective implementation of the rule, Ministry of Environment, Forest and Climate Change has provided a set of guidelines. The guidelines, in addition to other aspects, set out the duties required to be performed by the occupier along with the procedure. The rule also lists out the industrial activities and chemicals, which are required to be considered as hazardous. Bhilai Steel Plant (BSP) is engaged in the production of Steel from iron ore and other required raw materials. During the process of manufacture of steel and other associated materials hazardous gases are generated which are stored and used in the plant. In addition to this, some other hazardous chemicals, which are required in the manufacture of steel or produced as a by-product, are also being stored and handled by BSP. The major hazardous chemicals handled / stored by BSP includes coke oven gas (CO gas), blast furnace gas (BF gas), basic oxygen furnace gas (BOF gas), different acids etc. In view of this, BSP’s present and proposed activities are being scrutinized in line of the above referred “Manufacture, storage and import of hazardous chemicals rules” and observations / findings are presented in this chapter. Further BSP is already having a well-documented Disaster Management Plan for their existing plant covering all the chemicals / gases handled by BSP. The proposed project does not require handling and storage of any additional hazardous gases and so no additional plan is required for the current project.






At BSP, Energy Management Department (EMD) basically looks after the management of various liquid and gaseous fuels in the plant. EMD is responsible for proper distribution of available fuel gases viz. BF, CO and LD gas to all consumers. There are no gas holders for storing CO gas and BF gas, the network pressure is maintained by balancing the "Gas Make" and the consumption, continuously. During periods of surplus availability, the gases are burnt in high-pressure boilers. During shortages, restrictions are imposed on consumers, as per priorities approved by management from time to time. EMD comprises of an expert group specializing in energy auditing and monitoring work in the plant. Based on findings, the group suggests remedial measures to shops in order to bring down energy consumption. The group identifies areas for Energy Conservation and gets them implemented, and helps in bringing down energy rate to the target value. The current proposal envisages additional of two new units viz. Argon Rinsing Unit in SMS-III and Quenching and tampering facility in Plate Mill. Additionally, the current proposal seeks permission for bringing in operation of one additional coke oven battery and operating Blast furnace-1, SMS-1, RMP-1 and Blooming and Billet Mill for further 3 years. The hot metal, crude steel and finished steel production will be same as accorded in previous EC accorded in 2008. The assessment has been made in a systematic manner covering the requirements of the above-mentioned rules. Accordingly subsequent sections have been divided as follows: Applicability of the rule Description of hazardous chemicals Hazard identification Hazard assessment Consequence analysis Accordingly next sections are elaborated. However since Bhilai Steel Plant is already having a well-documented shop level Emergency preparedness Plan (EPP) in all units of the plant, the same has been covered in the Disaster Management Plan report.






1.1.2 Applicability of the Rule

The chemicals handled and involved in BSP at present are:

(1) Blast furnace gas; (2) Coke Oven gas; (3) BOF gas; (4) Benzol & Benzol products; (5) Tar & Tar products; (6) Liquid oxygen; (7) Liquid propane Gas; (8) Sulfuric Acid; (9)Chlorine; (10) Acetone; and (11) Calcium Carbide.

To decide whether the above mentioned industrial activities are likely to come within the scope of the above mentioned “Manufacture Storage and Import of Hazardous Chemicals Rules”, pertaining to occupiers guide to the hazardous chemical regulation -1989 with its subsequent amendments”, the threshold quantities mentioned in the rules are used as given in Table 1.1.

After comparison of the stored / handled and threshold quantities, it can be noticed that some of the chemicals are crossing the lower threshold quantities but are below the upper threshold quantities. Accordingly, rule nos. 7, 8, 9, 13, 14 and 15 will be






applicable, whereas for the other chemical, the stored / handled quantities are less than the lower threshold quantity. Accordingly only rule 17 i.e. preparation and maintenance of material safety data sheets for these chemicals are required. Rule -7 i.e. notification of site requires submission of a written report containing among other information the followings: Identification of major accident hazards The conditions or events which could be significant in bringing one about Brief descriptions of the measures taken Area likely to be affected by the major accident etc. However, a preliminary consequence analysis was carried out for the hazardous chemicals (crossing the lower threshold limit in Table 1.1) and the hazard extents were found to be near/within the plant premises.

Hazard Rating

a) Health

1. None 2. Minor 3. Moderate, could cause temporary incapacitation or injury 4. Severe, short exposure may cause serious injury 5. Extreme, short exposure may cause death

b) Flammability

1. None, Material does not burn 2. Minor, material must be preheated to ignite 3. Moderate, moderate heating is required for ignition and volatile vapours are

released 4. Severe, material ignites at normal temperature 5. Extreme, very flammable substance that readily forms explosive mixtures

c) Reactivity

1. None, stable when exposed to fire 2. Minor, unstable at high temp. or press and may react with water 3. Moderate, unstable but does not explode, may form explosive mixture with water 4. Severe, Explodes if heated or water added 5. Extreme, readily explosives under normal condition

From the above table it can be observed that Propoane (LPG), BF, BOF and CO gas are most `dangerous materials since all these are gaseous under ambient condition except these chemicals, all others are liquid at ambient condition. Further, among LPG, BF, BOF and CO gas, except Propane, all are stored (BF and CO gas supplied online in plant gas net work, without any storage) more or less under ambient temperature and pressure. The catastrophic potential of a hazardous substance depends both on toxicity and volatility. The ambient temperature vapour pressure of a substance is used as a measure of the ability to become air borne. Since LPG is gaseous at ambient temperature and pressure and is stored in pressurised condition to keep it in liquid form, the catastrophic potential of this chemical is maximum. Accordingly, the consequence






analysis carried out subsequently covers analysis of LPG only since the release of this quantity and in case of any eventuality it may affect the maximum area.

1.1.5 Hazard Assessment In the earlier section, type of hazard associated with different type of chemicals and the event of release of these chemicals is being identified. The category of hazard associated with different chemicals has also been identified. Propane or Liquefied petroleum gas (LPG) is stored under pressurised condition with elaborate arrangement for controlling storage pressure and distribution facilities whereas all other chemicals are stored under ambient temperature and pressure or in liquid condition. Brief Description of the Propane units Propane will be received in road tankers and unloaded by means of liquid pumps and vapour compressor and filled in the storage bullets. Unloading shall be done by first pumping liquid propane from tanker to storage vessels. After emptying liquid propane, which can be seen through sight flow indicator, the vapour compressor shall be put into operation for transferring propane vapour into storage vessels. Propane will be drawn from the storage bullets through the discharge liquid line and vaporised in the vaporisers. A separate natural vapour line will join the supply line after the vaporisers. Thereafter, pressure of Propane vapour will be regulated to a pressure of 1-2 kg/cm2 and supplied to the consumers. Propane storage bullets shall be welded construction, horizontal and cylindrical in design, the design of the bullets shall conform to IS-2825: 1969 or equivalent International Standards for unfired pressure vessels and shall meet the requirement of IS-6044 Part-II: 1972 In any plan hazardous situation arising due to: Failure in the monitoring of crucial process parameters e.g. pressure, temperature,

flow quantity etc. Failure in the utilities e.g. cooling water Failure control elements e.g. pressure, temperature level, flow controllers etc. Failure of components such as pumps, compressor etc. Failure of safety systems, safety valves / relief valves, sprinkler systems, alarm etc. Mechanical failure of vessels or pipe work due to excessive stress, over pressure,

corrosion etc. Wrong operation, failing to adhere to the safety norms etc. It has been mentioned that release of gas/LPG may lead to hazardous situation in case of accidental release of large quantity. Such situation is possible from the storage area






where bulk quantities are being stored. It is unlikely that small leakage through pipes, gaskets, glands or any other means within the plant proper itself (user points) will create a hazardous situation unless allowed to be released for a long time as will be established in the subsequent sections. It is expected that during such small leakage preventive steps will be taken within a specified time span. Effects of the above Hazards: The effect of accidents in these areas will be confined to the facilities only and can be controlled within the areas by the operating personnel themselves. At the extreme it may require the resources of the whole facility to control the effects but these are not at all expected to spill over to the community. The onsite emergency plan discusses the various precautionary measures to be taken in case of an accident occurring due to the handling of these hazardous chemicals within the plant premises.

1.1.6 Consequence Analysis In this section, accident consequence analysis to determine the consequence of a potential major accident on the installation, the neighbor-hood and the environment are being discussed by evaluating the consequence of incidence involving hazardous materials vis-a-vis LPG. Consequence analysis also involves assessment of release quantity which is again dependent upon chemical, storing condition, type of release, duration etc. Catastrophic flammable material normally involves the air borne release of these materials. A potential catastrophic release of flammable material would involve air borne release and subsequent explosion or fire i.e. a sufficiently large fuel – air mixture within flammable mix rapidly developed and finds a source of ignition. However LPG is stored under pressurized condition in liquid form and is expected to be distributed to the user points in gaseous form. Accordingly possible release quantities under different conditions has been computed and presented in Figs. 1.1 & 1.2. From the figure it can be noticed that release rate & quantity of liquid LPG is much more than gaseous LPG. The threshold quantity for flammable material (LPG) as per Hazardous Chemicals Rule, 1989 is 15000 Kg. Release of this quantity of flammable vapour in a few minutes has been used for deciding the catastrophic potential. From Figs 1.1 & 1.2 even though the pressure is different it can be noticed that this quantity of LPG liquid can be released through a 50mm diameter hole in 5 to 6 minutes whereas it will take more than 70 minutes. Thus spillage of LPG could be more catastrophic as it will be a steady continuous source of vapour.

Fig. 1.2: Computed Possible Release Quantities Under Different Conditions

When a pressurized liquefied gas is released from containment, a portion flashes off. Following flash off, residual liquid is at its boiling point and the vapourisation continues as a rate limit process. The second stage of rate limit vapourisation is usually regarded as relatively less important compared with the initial flash off. Fraction flash off is approximately 17% at 15°C as Butane. From the above it is clear that release of liquid LPG is potentially more catastrophic than release of vapour. Flammable releases cause harms as a results of fire or explosion. Flammable vapour cloud resulting from rapid, release of LPG is being calculated. Since the cloud center cannot be predicted, a conservative approach has been followed and it has been assumed that the cloud drift towards downwind from the point of release when the danger of ignition occurs. Assuming that the cloud would drift in any direction, the “Hazard Area” around LPG storage area has been established by drawing a circle of

radius equal to the distance, which may be affected due to heat intensity, if BLEVE occurs. A `BLEVE’ can occur, if a pressure vessel becomes completely filled with liquid. The temperature, rises and pressure relief capacity is insufficient to keep the internal pressure from exceeding tank strength. One of the hazards of a `BLEVE’ of a pressurized tank containing liquefied gas is the fireball created by combustion of the mixture of vapour liquid that is explosively dispersed by the sudden rupture. The sudden expansion of compressed vapour and the large quantities of vapour suddenly produced by liquid flashing combine to create a large ball of liquid droplets and vapour. The heat created by the burning of the dispersed liquid and vapour causes a powerful thermal updraft. As already explained, sudden release of a liquid stored at a temperature above its boiling point will result in the instantaneous and adiabatic vaporization of a fraction of the liquid. It is usually taken as half the tank capacity while calculating the radiative flux incident, on a target some distance away from the LPG tank. The assessments have been made on the assumption that maximum instantaneous release of total 150 tonne release. Unconfined vapoour cloud explosion is one of the most serious hazards of LPG. A vapour cloud explosion may cause harm by direct or indirect blast effects. The peak incident pressure at different distance due to explosion of various quantities of vapour cloud are being calculated and is presented in Table 1.3. The effect of this over pressure is presented in Table 1.4.

Major accident history in BSP During last 10 years there was no major accident due to handling, transportation of above chemical/gas as well as any other chemicals handled / transported inside the plant






1.2 DISASTER MANAGEMENT PLAN At Bhilai Steel Plant all facilities is designed and engineered with all possible highest safety measures and standard code of practices of engineering. In spite of all this, there may be some design deficiency or due to operation and maintenance shortfall may lead to accidental events causing damage to life and property. This Chapter presents an overview of environmental risks associated with various production facilities, ongoing / suggested remedial measures and outline of the emergency preparedness plan. Managing a disastrous event will obviously require prompt action by the operators and the crisis management personnel using all their available resources like alerting the people and other Plant personnel remaining inside, deployment of firefighting equipment, operation of emergency shut off valves, opening of the escape doors, rescue etc. Minimizing the immediate consequences of a hazardous event include cordoning off, evacuation, medical assistance and giving correct information to the families of the affected persons and local public for avoiding rumors and panic. Lastly, an expert committee is required to probe the cause of such events and the losses encountered, and suggest remedial measures for implementation so that in future such events or similar events do not reoccur. Unit wise/Shop wise Emergency preparedness Plan (EPP) has been prepared for major units of BSP to take care of any disaster in the steel plant and surrounding areas. In order to prevent occurrence of any disaster, the plant is provided with various safety and disaster control facilities. Normally, in the steel plant, no major disaster affecting population in nearby areas is foreseen. However, accidents inside the plant affecting workforce in vicinity cannot be ruled out. Work-force inside the plant are exposed to various high pressure system pipelines and vessels, acids and chemicals, fuel such as coal and furnace oil and other process equipment which, if not properly operated and maintained, can cause serious accidents affecting life and property in the vicinity of accident site. In addition to these, numerous material handling systems, heavy road transport, high-tension electric lines, level crossings, overhead cranes and various other handling and transport systems always have a chance of accidents. As Pre-planned procedures for handling emergencies helps in de-escalating original incident and minimizing the losses. BSP has Emergency Preparedness Plan (EPP) for major units of the plant. BSP submits compliance of the section 41-B of the factories Act, 1948 and On-Site Emergency Plan to Directorate, Industrial Health & Safety, C.G. Govt. along with all






data/ documents/information related to hazards at BSP, copy of the certificated received is enclosed as Annexure 7.2.1 (Volume II of EIA/EMP Report). Composite On-site Emergency plan with detail disaster control measures for Bhilai Steel Plant has been prepared by National Safety Council, Navi Mumbai based on Schedule 9A Rule 13(1) of the Madhya Pradesh/Chhattisgarh Control of Industrial Major Accident Hazards Rules, 1999. Copy of the Composite On-site Emergency plan enclosed as Annexure 7.2.2, Volume II of EIA/EMP Report. Anticipated Critical Emergencies Critical emergencies anticipated are given in following table
