Reactivity Profile

1,2-DIFLUOROTETRACHLOROETHANE is non-flammable. Incompatible with active metals such as potassium, sodium, beryllium, powdered aluminum, zinc, magnesium, and calcium. Reacts with acids.

Hazard

Toxic by inhalation.

Health Hazard

At high concentrations, 1,1,2,2- tetrachloro-1,2-difluoroethane affects the nervous system and causes pulmonary edema in animals; it is expected that severe exposure in humans will produce the same effects. There are no reports of adverse effects in humans.

Safety Profile

A poison by inhalation. Moderately toxic by ingestion. A sktn and eye irritant. When heated to decomposition it emits toxic fumes of Fand Cl-. See also CHLORINATED HYDROCARBONS, ALIPHATIC; and FLUORIDES.

Potential Exposure
