High-purity ethylene dichloride (EDC) is produced by PPG Industries at Lake Charles, Louisiana. PPG is one of the world's largest producers of ethylene dichloride and ships to customers in tank cars, tank trucks, barges and ocean going ships. A terminal in Chicago, Illinois, also makes tank car and tank truck shipments. USES Almost three-quarters of the ethylene dichloride produced in the U.S. is used as an intermediate for making vinyl chloride. Other important intermediate uses for EDC include making 1,1, 1-trichloroethane, trichlorethylene, perchlorethylene, ethylene amines and poly sulfide elastomers. Ethylene dichloride is also used as a scavenging agent in tetraethyllead fuel additive compounds to prevent lead salts and lead oxide from depositing on engine cylinder walls. Ethylene dichloride is an excellent solvent for greases, oils, fats and waxes. Due to the toxicity and flammability of EDC, other chlorinated solvents have displaced it in many applications. How ever, EDC has certain advantages and is still used for various solvent applications in chemical processing. exposures can bring on nausea, vomit ing, stomach pain, irritated mucous membranes, loss of appetite, liver and kidney failure and possible death. Numerous cases of ethylene dichloride poisoning, both fatal and nonfatal, have been documented by the National Insti tute for Occupational Safety and Health. When ethylene dichloride is ingested, the predominant characteristic is blood disorder, including clotting problems. With skin absorption or inhalation, the first effects are headache, weakness, eye irritation, cyanosis (blackening of skin) and nausea. Ethylene dichloride has been found in human milk and in the ex haled breath of nursing mothers who were exposed to the chemical. Ethylene dichloride in contact with eyes or skin can result in local pain and irritation. Dermatitis may result from removal of natural skin oils and mois ture, although permanent eye or skin in jury has not been known to occur. If EDC is held close to the skin, as by con taminated clothing, severe irritation and moderate edema and necrosis may result. TYPICAL PROPI Chemical Nairn Chemical Form' Molecular Weights 98.

Chronic Exposure There are reports of two mild cases of human exposure for periods of two to five months which showed symptoms of central nervous system depression and gastrointestinal upset with nausea and vomiting. These persons recovered when removed from exposure. The liver and kidneys may be damaged by prolonged or repeated inhalation of the vapor. Animal studies conducted by the National Cancer Institute (NCI)(1) sug gested that ethylene dichloride can cause cancer in rats and mice by oral adminis tration. However, a later EDC inhala tion study of rats and mice by Maltoni, et. al'1' failed to confirm the NCI findings. The current OSHA permissible expo sure limits for EDC are 50 ppm (8-hour TWA) 100 ppm (ceiling) and 200 ppm acceptable maximum peak above the ceiling concentration for 5 minutes during a 3-hour period. PPG has established an internal permissible ex posure limit for EDC of 5 ppm (8-hour TWA). Although no evidence now exists showing that ethylene dichloride can cause cancer in human beings, PPG strongly suggests that EDC users review their health programs and operations and institute operating and house keeping practices designed to limit employee exposure as much below cur rently established exposure limits as practical. HANDLING AND STORAGE Ethylene dichloride is a flammable liquid. It introduces a fire hazard wherever it is handled, stored or used. At high temperatures, such as occur in open flames, it decomposes to give off toxic and corrosive gases. Mixed with air at Spcffica^onn^tYp|i Inalymis: .
