| Human Toxicity Excerpts | THE POTENTIAL HAZARDS INCL PULMONARY EDEMA & CORNEAL DAMAGE ARE REITERATED.INHALATION OF A MINUTE QUANTITY PROVED FATAL TO A 25-YR-OLD WHO SPILLED A FEW MILLILITERS OF FLUID CONTAINING METHYLFLUOROSULFONATE ON HIS CLOTHING.EVALUATED IN 2 IN VITRO ASSAYS, SALMONELLA REVERSE MUTATION ASSAY OF AMES & CELL TRANSFORMATION ASSAY OF STYLES. FINDINGS WERE CONSISTENT WITH THIS MATERIAL BEING A POSSIBLE CARCINOGEN.MARKEDLY TOXIC BY ALL ROUTES STUDIED (ORAL, INHALATION, OCULAR & DERMAL) PARTICULARLY BY INHALATION ROUTE. |
| Non-Human Toxicity Excerpts | EYE IRRITATION STUDY IN RABBITS SHOWED THAT IT WAS SEVERELY IRRITATING & CAPABLE OF PRODUCING TOXIC SIGNS & DEATH BY OCULAR ROUTE. DERMAL IRRITATION STUDY IN RABBITS SHOWED THAT IT WAS NOT ONLY CORROSIVE TO SKIN BUT ALSO CAPABLE OF CAUSING DEATH BY THIS ROUTE. |
| Antidote and Emergency Treatment | REMOVE CONTAMINATED CLOTHING IMMEDIATELY & DISPOSE OF WITH GREAT CARE. PROTECT PERSONNEL PROVIDING CARE FROM CONTAMINATION.IMMEDIATE ADMIN OF CORTICOSTEROIDS SHOULD BE CONSIDERED IF THIS AGENT IS THOUGHT TO HAVE BEEN INHALED. CONTINUOUS CLOSE OBSERVATION DURING FIRST 24 HR IS NECESSARY. |
