Ethylene Bichloride dichloride has been found in human milk and in the exhaled 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 natu ral skin oils and moisture, although perma nent eye or skin injury has not been known to occur. If EDC is held close to the skin, as by contaminated clothing, severe irritation and moderate edema and necrosis may result. 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 depres sion 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) suggested that ethylene dichloride can cause cancer in rats and mice by oral administration. How ever, a later EDC inhalation study of rats and mice by Maltoni, et al failed to confirm the NIC findings. Ethylene dichloride is listed by the National Ibxicology Program (NTT) in Group II (substances that may reasonably be anticipated to be a carcinogen based on animal studies). It is not listed by OSHA or the International Agency for Research on Cancer (IARC). The current OSHA permissible exposure limits for EDC are 50 ppm (8-hour TWA) 100 ppm (ceiling) and 200 ppm acceptable max imum peak above the ceiling concentration for 5 minutes during a 3-hour period. PPG has established an internal permissible exposure 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 sug gests that EDC users review their health programs and operations and institute Ethylene dichloride serves as an Intermediate In the manufacture of vinyl chloride, leading to polyvinyl chloride. Vinylaiding Is one application. operating and housekeeping practices designed to limit employee exposure as much below currently established exposure limits as practical. Additional health and safety information is contained in the Material Safety Data Sheet, available on request. Handling and Storage Ethylene dichloride is a flammable liquid. It introduces a fire hazard wherever it is handled, stored or used. At high temper atures, such as occur in open flames, it decomposes to give off toxic and corrosive gases. Mixed with air at ordinary temper atures, ethylene dichloride is explosive within the limits of 6.2 to 15.6% by volume. Fire and explosion hazards can be minimized by adequate ventilation, the proper types and arrangement of equipment, and rea sonable precautions and care in handling. Packaging and Shipping PPG Industries delivers ethylene dichlo ride by tank truck, tank car, barge and ship from its Lake Charles, Louisiana plant. Thnk truck shipments also can be made from a terminal in Chicago, Illinois. Thnk car capabilities are 10,000 and 20,000 gallons. Thnk truck capacity is generally 4,000 gallons. Samples and Service Samples of ethylene dichloride are avail able in various sizes to meet customer requirements. The technical service staff of PPG Industries' Chemicals Group is available for con sulting on handling, storage and use. PPG Industries, Inc.

PPG, one ofthe world's largestproducers, ships ethylene dichloride to customers in tank trucks, tank cars, barges and oceangoing ships. A terminal in Chicago also makes tank truck shipments. General Application Almost three-quarters of the ethylene dichloride produced in the United States 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 polysulfide elastomers. PPG recommends that any application of ethylene dichloride be very carefully con sidered to insure that personnel are ade quately protected from exposure. Use of EDC as a solvent for general applications is not authorized. This material must be used in an enclosed system to minimize exposure. Government Speclfcations PPG technical-grade ethylene dichloride meets the chemical and physical require ments of military specifications MIL E-10662. H alth Hazards Ethylene dichloride can be taken into the body by ingestion, inhalation or skin absorption. By any of these means it can be highly toxic. Acute poisoning may cause headache, dizziness, feelings of drunkenness, loss of consciousness, internal bleeding and death. Repeated exposures can bring on nausea, vomiting, 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 Institute for Occupational Safety and Health. When ethylene dichloride is ingested, the predominant characteristic is blood dis order, including clotting problems. With skin absorption or inhalation, the first effects are headache, weakness, eye irritation, cyanosis (blackening of skin) and nausea. Ethylene Typical Properties Chemical Names Chemical Formula Molecular Weight Ethylene dichloride; ethylene chloride, 1, 2-dichloroethane CHjCICH.Cl 98.97 Description Ethylene dichloride is clear and colorless, but darkens slowly upon exposure to sunlight.
