Chlorine protective equipment

All people on a chlorine plant are advised to carry escape-type respirators. The use of filter masks is prohibited where there is a risk of a high concentration of chlorine. Anyone who enters an area with high chlorine concentrations should be equipped with self-contained breathing apparatus and full protective clothing suitable for dealing with liquid chlorine. Protective equipment, safety showers, eye-wash facilities, and emergency kits [24] must be quickly accessible. 

AH volatile organic solvents are toxic to some degree. Excessive vapor inhalation of the volatile chloriaated solveats, and the central nervous system depression that results, is the greatest hazard for iadustrial use of these solvents. Proper protective equipment and operating procedures permit safe use of solvents such as methylene chloride, 1,1,1-trichloroethane, trichloroethylene, and tetrachloroethylene ia both cold and hot metal-cleaning operations. The toxicity of a solvent cannot be predicted from its chlorine content or chemical stmcture. For example, 1,1,1-trichloroethane is one of the least toxic metal-cleaning solvents and has a recommended threshold limit value (TLV) of 350 ppm. However, the 1,1,2-trichloroethane isomer is one of the more toxic chloriaated hydrocarboas, with a TLV of only 10 ppm. 

TETRACHLOROVANADIUM (7632-51-1) Keep away from water (decomposes, producing heat and forming hydrogen chloride, vanadium trichloride, vanadium oxychloride), radiant heat, and flammable materials lithium, chlorine, and trifluoride. Decomposes slowly to vanadium trichloride and chloride. Fumes in moist air open containers in dry, oxygen-free atmosphere or in inert gas, wearing appropriate personal protective equipment. Chill to below 68°F/20°C before opening. Corrosive to metals, especially in the presence of moisture. 

The heavy-bunker approach would make maintenance difficult and in many cases would require workers to don full protective equipment before entering the confined area. It is not suitable for loading/unloading systems and is largely confined to the erection of small buildings for confinement of reactors that have the potential for a sudden release of considerable energy or quantities of chlorine. The Eimo Chlor conclusion is tiiat no credible scenario justifies (this approach) for imits containing liquid chlorine. ... 

The Coast Guards of Canada and the United States, each with its own added requirements, regulate barge transport of chlorine (P79). There is not yet a Coast Guard-defined procedure for emergency response plans, but training is covered in 29 CFR 1910.120. This also covers procedures, clean-up activities, and the use of personal protective equipment. Protective equipment is also the subject of Cl Pamphlet 65 and 29 CFR 1910.132-134. 

Facility design also should follow Pamphlet 17 and local codes. Structures should be fire-resistant, and no flammable materials should be kept in the building unless separated from chlorine by firewalls. There should be at least two exits from each area where chlorine is stored or handled and at least two stairways or ladders at each platform. Emergency egress routes should be clearly and prominently marked and kept clear at all times. Many facilities use chlorine monitors to detect any release of chlorine (P73). Ventilation requirements are site-specific but should follow best industry practices [74]. Respiratory protective equipment should be in ample supply. This should meet all governmental requirements it is covered in Section 16.2.1.3. 

Protective Equipment. Section 16.4.1 discusses safety equipment in general and gives some guidelines for the use of PPE when exposure to chlorine is possible. The first line of defense against exposure to chlorine gas is the ubiquitous mouthpiece respirator. No one should be present on a chlorine plant or chlorine-using facility without one of these. However, their function is strictly to permit escape from a contaminated area. When someone must work in an area where chlorine gas may be present, some way of supplying uncontaminated air is necessary. The work may be standard maintenance...

Chlorine is listed as a toxic and reactive highly hazardous chemical in Title 29 CFR Part 1910 of the U.S. Occupational Safety and Health Standards. The requirements for handling chlorine are well documented. Protective equipment is required to prevent inhalation and contact with eyes, skin, and clothing. Chlorine is often handled in confined areas to prevent accidental releases. These areas require continuous monitoring to detect chlorine leaks, air scrubbers. 

Glacial acetic acid is corrosive it can cause burns on the skin and on mucous membranes in the nose and mouth. Its vapors are also hazardous. Dispense it in the hood and use personal protective equipment. Avoid contact with skin, eyes, and clothing. Sodium hypochlorite emits chlorine gas, which is a respiratory and eye irritant. Dispense it in a fume hood. 

Safety. Use of chlorine gas requires adequate ventilation, tank and cylinder storage, leak-detection equipment, emergency protcxx)ls, personal protective equipment, operator training, and fire department approval and inspection of installations.
