HEALTH HAZARD INFORMATION(continued) <br /> Reddening of the eyes Nau^�a • <br /> Irritation of the throat Her, .che <br /> Palpitation Weakness of arms and legs <br /> Difficulty in breathing Giddiness <br /> Salivation Collapse <br /> Numbness Convulsions <br /> Convulsions, coma and death due to resp?ratory arrest may <br /> occur without first aid or medical treatment. <br /> Cyanosis (bluish discoloration of the skin) is a sign that <br /> follows cardiovascular collapse and apnea (absence of <br /> breathing) . Reported chronic effects of acute, severe <br /> overexposures may not be due to cyanide per se but to the <br /> hypoxic (oxygen deficient) state. There appears to be no <br /> cumulative effects from repeated exposures. Reports of <br /> chronic thyroid effects from occupational exposure to <br /> cyanide fail to establish a well defined cause-effect <br /> relationship.; <br /> Individuals with preexisting diseases of the central nervous <br /> system may have increased susceptibility to the to::-city of <br /> excessive exposures. <br /> Carcinogenicity None of the components in this material is listed by IARC, NTP, <br /> OSHA, or ACGIH as a carcinogen. <br /> Exposure Limits <br /> Sodium Cyanide <br /> AEL' (Du Pont) None Estat' shed <br /> TLV (ACGIW 5 :ng/m3, as CN -8 Hr TWA, skin <br /> PEL (OSHA) 5 mg/m3,as CN -8 Hr TWA, skin <br /> Other 'OTHER INFORM/ . ION ON THE "SKIN" <br /> NOTATION IS C(_ AUED IN THE ADDITIONAL <br /> INFORMATION ANL) REFERENCES SECTION. <br /> AEL is Du Pont's Acceptable Exposure Limit. Where -mmentally imposed occupational exposure limits which are lower than <br /> the A.. a in effect,such limits sliall take precedence. <br /> Safety Precautions Emergency pre-planning and training are needed before <br /> beginning to work with sodium cyanide since prompt treatment <br /> is essential in cases of cyanide poisoning. Always have <br /> Cyanide Antidote Kits on hand. <br /> Do not breathe dust, mist, or hydrogen cyanide gas. Do not <br /> get in eyes. Avoid contact with skin and clothing. Do not <br /> carry foodstuffs, beverages, or tobacco where contamination <br /> with cyanide is possible. Wash thoroughly after handling. <br /> Wash contaminated clothing before reuse. <br /> FIRST AID <br /> FIRST AID AND MEDICAL TREATMENT <br /> (continued) <br /> i <br /> 1252CR Page 4 <br />
