Thompson NEV 025020 J 738283 - lf - TOXICITY AND HAZARDS Safety of operations in the Aroclor plant depends on the In dividual operator. Materials being handled and operations must be observed closely to guard against the following: Cause Action to Prevent Chlorine Gas Chlorine gas is a very toxic corrosive gas. Leaks or high pressure can occur to liberate it. Report chlorine gas exposure im mediately for treatment with antidote. Milk may be used in mild cases to relieve throat irritation. Oxygen from the resuscitator in the Dispensary is available. Keep gas mask in good condition. Keep a good canister in the mask. Use these type masks only in chlorine concentrations to 2-3# chlorine in air. Use a Scott Air Pak in concentra tions of chlorine gas above 3# in air. One unit is available out side the west well of the drumming shed. If caught in chlorine gas without mask, hold your breath and go cross wind until you are out of range of the gas. Place a hand kerchief over your nose in small quantities of chlorine. Report all chlorine leaks for re pair immediately. Make temporary repairs with tape, if possible. In case of a major chlorine leak, the source of chlorine gas must be stopped. Notify the chlorine plant immedi ately if the pressure on the chlorine manifold exceeds 50 pslg. NEV 025029 738284 - 19 - Cause Thermal Burns Contact with hot unin sulated product lines at the chlorinators and still areas. Contact with uninsulated steam lines and open steam. Contact with hot Aroclors from broken lines or leaks. Contact with open flames at Therminol furnace or from heating lines in the department. Explosion An explosion could occur in the chlorinators by slugging liquid chlorine to the distributor. Slugs of liquid chlorine could react fast enough to cause excessive pressure in the vessel. A rupture of the chlorinator rupture disc could occur. Action to Prevent Know that contact with equipment and product will cause a thermal burn due to the high temperatures. Make changes in operations with this hazard in mind. Know the first aid treatment for burns. Wear gloves and long sleeve Bhirts with the sleeves rolled down when operating. Gloves and clothing can make the difference between first and second degree burns. Report uninsulated lines for r e pair of insulation. Use only steam lines with hose and hose clamps in good condition. Use the cotter pin provided at the hose station to hold hose in place. The following operations are hazardous and should be done with care: 1) Catching samples at the chior1nator sampling points. 2) Drawing bottoms at stills. Observe operation of the chlorine vaporizer. Pipe lines from the vaporizer will be frosted if liquid chlorine is present. in case chlorine feed lines are frosted, close chlorine feed valve to the vaporizer. Check steam addition to the vaporizer. Do not start up until source of trouble has been located. Observe temperature of the chlorinator periodically and be sure it is not too hot. A high tempera ture alarm and shutdown is provided NEV 025030 738285 20 Cause Action to Prevent Falls Slipping on cement floors, stairs, Aroclor on floor, ice conditions; tripping over objects (hose, pipe, valve handles, etc.); or losing footing on ladders, etc., can cause fallB. The majority of minor, serious, and near-miss injuries in the Aroclor Department are the result of falls. Prevention is always within the ability of the operator by use of expert operating prac tices'. The following items should be done 1) Return hose to rack after using 2) Keep operating areas clean of all foreign objects. 5) Return ladders to racks when not in use. *0 Keep gloves on and hands out of pockets, especially going up stairs. 5) Place guards around any area that presents a hazard that should be guarded. Poor lighting due1to burned out bulbs should be corrected at once. Poor lighting due to inadequate facilities should be reported. Spills must be cleaned up im mediately following their occurrence. Spills are to be reported on the log sheets. Fires Biphenyl ignition. Chlorine problems in the vaporizer allow ing reaction with steam to release hydrogen. Therminol furnace and still burner backfire. Area must be clear of trash or flammable materials. Use trash skips and cans. Smoke only in areas so designated. Use spark producing equipment only with a fire permit and proper inspection. NEV 025031 738286 21 Cause Action to Prevent Fires (continued) Wood, rags, or paper on hot lines. Use care In lighting gas torch or the still furnaces. Sparks from welding apparatus or open flames. Observe visitors in the plant and be sure they observe safety rules. Chemical Handling Chlorine Gas This is a corrosive gas which is toxic. Leaks or back pressure can occur and liberate chlorine gas in the area. Operators should have their cartridge type respirators handy at all times while in the area. Use of gas masks is explained in Section 1 - Chlorine Gas. If you are caught without a gas mask, and large amounts of chlorine gas are liberated, hold your breath and go cross wind until you are out of range of the gas. Once out of the area, obtain an emergency gas mask and return to the area and correct the trouble. A victim of chlorine gas fumes must be removed as quickly as possible from the gaseous area. Place patient on his back with head and back elevated. Milk may be used in mild cases as a relief from throat irritation. If the patent has stopped breathing, start artificial respiration immediately. Biphenyl Biphenyl is a flammable material which will burn. B u r n ing should not be done in the presence of biphenyl or biphenyl vapors. The melting point is 68.7C., and the auto ignition temperature is 258C. Inhalation of biphenyl fumes is not recommended, since it can cause a drugged effect on the person. Ferric Chloride Ferric chloride is a black-brown solid. It causes only Blightly irritating effects on the skin or mucous m e m branes. When heated, it will decompose and release toxic fumes of chlorine. It will react with water to produce toxic and corrosive HC1 fumes. NEV 0 25032 738287
