Reactivity Profile

PERTHANE (TM) is sensitive to heat. PERTHANE (TM) is incompatible with alkalis. PERTHANE (TM) is readily dehydrochlorinated. PERTHANE (TM) is slightly corrosive to iron, zinc, and aluminum.

Health Hazard

Mildly toxic by ingestion; the oral medianlethal doses in all experimental animalswere >5000 mg/kg; however, producedmoderate to severe effects when administeredintravenously; toxic properties are somewhatsimilar to those of DDT; susceptible tostorage in fat; also bioaccumulative; ateratogenic substance; sufficient evidenceof carcinogenicity in mice, but inadequateevidence in other animals; cancer-causingeffects in human unknown.LD50 oral (rat): 6600 mg/kgLD50 oral (wild bird): 9000 mg/kgLD50 intravenous (rat): 73 mg/kg.

Fire Hazard

Flash point data for PERTHANE (TM) are not available. PERTHANE (TM) is probably combustible.

Safety Profile

Poison by intravenous route. Mdly toxic by ingestion. Questionable carcinogen with experimental carcinogenic and tumorigenic data. Experimental teratogenic and reproductive effects. Mutation data reported. A pesticide. When heated to decomposition it emits toxic fumes of Cl-. See also CHLORINATED HYDROCARBONS, ALIPHATIC.
