HOT METAL SURFACES TO PRODUCE TOXIC AND CORROSIVE PRODUCTS.

Do not get in eyes, on skin or clothing. Avoid breathing vapor or mist. Keep container closed. Use only with adequate ventilation. Wash thoroughly after handling. Keep away from heat, sparks and flame. Emptied container retains vapor and product residue. Observe all labeled safeguards until container Is destroyed. Do not reuse this container. Do not cut or weld on or near this container. Although this material is stable in long-term storage in carbon steel containers, it may gradually decompose in the presence of ferric chloride. The presence of excess levels of moisture, especially as a separate layer, should be avoided since it may lead to corrosion of carbon steel and formation of feric chloide. It is recommended that containers be raised above floor or ground during extended storage periods to prevent container corrosion due to standing water. Prior to putting a storage system into service for this product, or after maintenance, ensure that the system is dry and oxygen-free. Purging the system with dry nitrogen is recommended. In addition, containers previously exposed to hydrogen chloride (for example, from impurities in chloinated blowing agents or solvents), should be thoroughly cleaned first. Investigate engineering techniques to reduce exposures below airborne exposure limits. Provide ventilation if necessary to control exposure levels below airborne exposure limits (see below). If practical, use local mechanical exhaust ventilatior at sources of air contamination such as open process equipment. Where there is potential for eye contact, wear chemical goggles and have eye flushing equipment available. Wear appropiate chemical resistant protective clothing and chemical resistant gloves to prevent skin contact. Consult glove manufacturer to determine appropiate type glove material for given application. Wear face shield and chemical resistant clothing such as a rubber apron when splashing may occur. Rinse contaminated skin promptly Wash contaminated clothing and clean protective equipment before reuse. Wash skin thoroughly after handling. Avoid breathing vapor or misl. When airborne exposure limits are exceeded (see below), use NIOSH approved respiratory protection equipment appropiate to the material and/or its components. Consult respirator manufacturer to determine appropriate type equipment for given application. Observe respirator use limitations specified by NIOSH or the manufacturer. For emergency and other condilions where exposure limit may be significantly exceeded, use an approved full face positive-pressure, self-contained breathing apparatus or positive-pressure airline with auxiliary self- contained air supply.

No allergic skin response was observed in guinea pigs following repeated skin exposure to this material using the maximization procedure. Inhalation of high concentrations of this material (generally exceeding 10000 ppm; produces a transient anesthetic effect in rodents. As with many other halogenated hydrocarbons, inhalation of this material, followed by intravenous injection ol epinephrine to simulate human stress reactions, resulted in heart sensitization at levels above 5000-10000 ppm in dogs and monkeys. Longer term inhalation studies of up to 13-weeks duration at concentrations of this mateial up to 20000 ppm resulted in minor changes in body weight and slight changes in blood chemistry in rats. Repeated inhalation of this mateial vapors at levels up to 15000 ppm for 16-weeks did not produce evidence of nervous system toxicity or behavioral effects in rats. Long-term inhalation (2-years) of high concentrations of this material (5000 and 20000 ppm) caused an increase in the incidence of benign, not life-threatening tumors of the testes in rats. No exposure-related effects or tumors were observed at 1500 ppm in this study. No birth defects were noted in rabbits exposed to this material by inhalation during pregnancy at levels up to 12500 ppm: signs of maternal loxicity were noted at 4200 ppm or above. No birth defects were noted in rats exposed to this material by inhalation during pregnancy at levels up to 20000 ppm; toxic effects were noted in the mothers and their offspring. In a reproduction study, reductions in litter size, total liter weight and growth rate were observed in rats exposed by inhalation to 20000 ppm of this mateial for 2-generations. Delayed sexual maturity of male offsping from parents exposed to 8000 and 20000 ppm may have been related to the lower growth rate. This material has generally produced no genetic changes in standard tests using animals (in vivo tests) and animal or bacterial cells. Metabolism studies in rats exposed by inhalation show that this mateial is not metabolized Avoid contact with hydrochloic acid, alkali or alkaline earth metals, finely powdered metals (aluminum, magnesium, zinc) and strong oxidizers since they may react or accelerate decomposition.
