The peculiar phenomena with accidents occurring in chemical industries is that the risks involved are invisible and silent in nature. To make it more clear, the process materials are handled in closed systems and as such nothing is visible. Also, because of the effect of the toxic gases and vapors on the human system, one may riot be able to identify when an accident happens to him. In view of the above, there is no necessity to emphasize the importance of safety and accident prevention in industries. If safety precautions and safe procedures are practiced, it will definitely result in accidents prevention and will save the lives of many people. PREVENTIVE STEPS: MANAGEMENT CONTROL Eliminating unsafe Discovering Eliminating unsafe condition causes acts By means of By means of By means of 1. Safe guarding all machines 1. Investigation of 1.

Suitable, safe design and construction. 4. Risk Assessment 7. Safe arrangements and work 5. Inspection of methods. Plants' and 8. Adequate Ventilation and equipment illumination. 9. Safe dress and personal protective equipment. 35 In Accident prevention, the following four E’s play a prominent role. 1. Engineering Revision : It is a method of removing unsafe mechanical or physical conditions by changing manual work to mechanised work. Unguarded machines are adequately guarded. New devices are introduced in the work. Modern technique, revised procedure are adopted by rectifying the unsafe process or system of work. 2. Education and Training : It is to be ensured that the worker is qualified to do the job safely and efficiently. It is also important to see that he understands the work methods thoroughly. He should be further educated, by giving him job instructions with necessary emphasis on the safety aspects. New employees should be given basic training, orientation training which will be helpful in doing the job safely. Periodical refresher training is to be imparted to the regular employees on Health, Safety, Environment and Firefighting. Safety talks, Safety films, Safety courses, Safety booklets, Safety bulletins and Newsletters and Safety Posters, are the important methods of Safety education and training. 3. Enthusiasm : It is a positive approach for Safety promotion. Workers are motivated by introducing Safety awards or Safety incentive schemes. This helps to prevent accidents. Employees can be made to participate in Safety promotional activities such as Safety Slogan competitions, Safety suggestions, Safety Quiz and Elocution competitions. Safety consciousness and safety attitude of an employee are considered for his promotion. 4. Enforcement : Enforcement is the last resort to improve safety. To restore and achieve the safety performance, a minimum of discipline is required. Violation of safety rules should be viewed seriously, taking disciplinary action, if necessary. Accident prevention is a team effort, so Safety is everybody's business and not a one man show. Personal adjustment, persuasion and appeal to workers will help in improving safety. Considering the skill and experience on the job, job rotation among the workers can be given. It is one way of fixing proper man for proper job. In spite of every precaution on the part of the manufacturers of equipment, suppliers of the materials, and supervision by the safety personnel, accidents do happen. The reason is the human error. With the most modern engineering know- how, the process and machinery can be designed safe, and materials can also be handled safely. It is only by religiously following the safety regulations and procedures the accidents due to human failures can be prevented. Accidents severely limit production and efficiency. Needless destruction of life and health of people is a moral evil, and every individual has a moral obligation to human society to prevent accidents. 36 OUT OF THIS NETTLE, DANGER, WE PLUCK THIS FLOWER, SAFETY --- HENRY IV ACCIDENT REPORTING AND INVESTIGATION Accident Reporting System Classification of incidents Reportable Accident: An accident which involving an employee or contract work men causes bodily injury by reason of which the injured person sustained major injury typically not able to resume his duties within 48 hours, immediately following the accident and shall be reported to factory inspectorate in prescribed format.

Tripping hazards due to materials/protrusions. 7. Open manholes / trenches. 8. Inadequate lighting / ventilation. 9. Poor housekeeping. The requirement of safety systems in chemical process industry is of two types. 1. Protection of operating equipments. 2. Safety for operation and maintenance personnel. The aim of safety systems are 1. To detect and provide audio visual alarm regarding abnormal or dangerous condition leading to the failure of equipment. 2. To detect and automatically provide signals or alarms on audio visual devices regarding change in process variable from the desired limit and thus approaching a hazardous condition. Safety in process encompasses the safe environment wherein the persons engaged in any physical activity are able to work safely. 63 To achieve this goal, following are to be ensured. 1. Safe working practice for personal safety. 2. Safe working condition to ensure personal safety. Many chemicals handled in the process industry are hazardous in nature. Leakage of hazardous chemicals clubbed with high pressure and temperature poses a biggest threat. A process industry basically consists of three major mechanical items. 1. Static equipment : Storage tanks, vessels, heat exchangers, and columns 2. Rotating equipment :Pumps, compressor, blower and turbines. 3. Bulk material handling :Piping, valves, traps, flanges and couplings. a. Leakages in Static Equipment The following factors mainly influence the leakage from any static equipment. 1. Aging 2. Corrosion 3. Human error 4. Poor design details 5. Improper materiel of construction 6. Faulty operation 7. Flying object hitting the equipment b. Leakages in Rotating Equipment 1. Leakage from moving parts 2. Leakage from connected pipes 3. Leakage from the casing c. Piping and bulk material leakage 1. Pipes 2. Valves 3. Flanges 64 MACHINE GUARDING Introduction: Safeguarding dangerous parts of machinery is considered as an important aspect in accident prevention. The high severity rate of accidents caused by dangerous parts of machinery justify the importance attached to machine guarding. Principles of Machine Guarding : Guards are to be provided to the following 1. Moving parts of prime movers including wheels. 2. Transmission machinery and 3. Every dangerous parts of any other machinery. Basic requirements of guards: Guards should PINCH (NIP) POINTS 1. Protect the human beings 2. Not interfere with efficiency 3. Be fire-proof 4. Allow repairs 5. Allow lubrication 6. Be well constructed 7. Be well secured 8. Not create new hazards 65 Types of machine guards: 1. Safety by construction 2. Fixed Guards 3. Automatic guards 4. Interlock guards 5. Trip guards 6. Positional or distance guards 7. Safety by position of machinery 8. Other types. 1. Safety by construction: This is an important aspect of machine guarding which needs the attention of the machine designer. Good fencing by design is found in the gear boxes of the capstan turret lathes, milling machines and radial drills, all of which have materially contributed to safety. 2. Fixed guards: 66 The fixed guard is considered in preference to all other types as it always prevents access to the dangerous parts of the machine. The advantages of the fixed guards are a. They are stationary b. They are not having moving parts and c. Very little maintenance is required. Fixed guards are adjustable to accommodate different set of tools for various kinds of work. The fixed guards are found on a. Power press b. Flattening machine c. Milling machine d. Drilling machine etc. e. Pumps and compressors 3. Automatic guard: Automatic guard may be used where neither a fixed guard nor an interlocking guard is practicable. The types of automatic guards are a. Sweep away device b. Pull away device It is actuated by a moving member of the machine to which it is fitted. All automatic guards require careful designing when a rapid motion is required for efficiency in action. The type of guard is fitted in stroke machines, power presses, paper cutting machines and hand fed machines. 67 4. Interlock guard: The principle of the interlock guard is that the control gear to start the machine cannot be operated until the guard is moved by hand into such a position that the operator cannot reach the position of danger. When the machine is in motion the guard cannot be opened. Interlocking guards may be mechanical, electrical, pneumatic or a combination of above types. 5. Trip Guard: Whenever the guard is disturbed from its usual position, the power is cut off and the machine gets tripped. The mechanism itself must be of sufficiently sensitive character to disconnect the power quickly. It is used in laundry, ironing machine, planten printing machine, conveyors etc. 6. Position Guard: a. Two hand controls are those which work on a principle of providing multiple control such as twin push buttons or levers. The worker has to use both his hands to operate the twin controls to operate the machine. b. Distance Guard is one in which a bar or bars are so placed to prevent the fingers of the operator reaching he danger zone. The distance between the danger point and guard has to be varied according to the dimensions of the opening. 7. Safety by position of machinery: This is not a guard at all. The machinery, by virtue of its position is considered as safe. Fixed guard should be provided in such cases as it cannot be taken out under any circumstances. Only during maintenance or repair the worker will go near the machine after stopping and electrically disconnecting the supply. 68 8. Colour coding : The machine guards are painted in red orange colour so that they are clearly visible when they are in position. ACCIDENTS ARE RARE WHEN MACHINE GUARDS ARE THERE MACHINE GUARDS ON STAY ALIVE STOP ACCIDENT 69 SAFETY IN THE USE OF HAND TOOLS I. Screw Driver: 1. Do not use a blunt screw driver, since, this requires more energy to work and it damages the screw also. 2. Do not use a screw driver as a chisel and do not hammer on the handle. 3. Do not use a screw driver for matching the flange holes. Use a hole-bar. 4. Do not keep the job on your palm and use the screw driver. Use a table because the screw driver may cause injury to your palm. 5. Do not bring the job close to your body while using the screw driver because the slipping screw driver may pierce your body. 6. When the screw driver is used as a connector, ensure that the metal portion is sleeved. II. Chisel: 1. Do not use a chisel with mushroom head. Trim the mushrooms and use
