This mixture Is one that Is being considered as a part of a new process. What are its hazards and what are the precautions necessary for its safe handling? How does it compare toxicolog- lcally with ethylene dlbromlde alone? CONCLUSIONS Ethylene dibromide containing free bromine (1 HBJ-X) is moderately high in acute oral toxicity, markedly Irritating to the eyes, and seriously corrosive to the skin. The material may be handled safely only if chemical workers goggles and protective clothing, as described, are worn. By way of comparison, the undiluted mixture is more hazardous to handle than ethylene dlbromlde when considering both the eyes and the skin. This, of course, is most likely due to the presence of the free bromine which Is known to be corrosive to the skin. Continued DO 130618 CONFTDFNTTAI
