Explanation of Carcinogenicity:NONE
Effects of Overexposure:EYE, SKIN & RESPIRATORY TRACT IRRITATION.
PROLONGED OR REPEATED SKIN CONTACT MAY RESULT IN ITCHING RASH
CAHRACTERIZED BY MACULAR, POPULAR, AND VESICULAR ERUPTIONS USUALLY
FOLLOWED BY SECONDARY INFECTI ON. CAN CAUSE DEATH THROUGH CHEMICAL
ASPHYXIA. MAY CAUSE HEADACHE, WEAKNESS, NAUSEA, DIZZINESS AND LOSS
OF APPETITE.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH PRE-EXISTING
DISEASES OF THE CENTRAL NERVOUS SYSTEM MAY HAVE INCREASED
SUSCEPTIBILITY TO THE TOXICITY OF EXCESSIVE EXPOSURES.

First Aid:PLAN & PRACTICE ACTIONS TO BE TAKEN IN CASE OF CYANIDE
EXPOSURE BEFORE BEGINNING WORK WITH CYANIDES. IMMEDIATELY GIVE
VICTIM OXYGEN AND AMYL NITRITE WHILE WAITING FOR INTRAVENOUS
INJECTIONS FROM MEDIC AL PERSONNEL. INHALATION: REMOVE TO FRESH
AIR/CPR. EYE: FLUSH WITH PLENTY OF WATER. SKIN: REMOVE CONTAMINATED
CLOTHING & WASH SKIN. INGESTION: GIVE 1% SODIUM THIOSULFATE
SOLUTION & INDUCE VOMITING.
