Reactivity Profile

tetrachloronaphthalene is non-flammable, but combustible. Gives off irritating or toxic gases in a fire. Incompatible with strong oxidizing agents. Reacts violently with aluminum, with bases, and with liquid O2.

Hazard

Combustible. Toxic by inhalation and skin contact. Liver damage.

Health Hazard

Tetrachloronaphthalene may cause liver injury. Experiments on human volunteers showed tetrachloronaphthalene to be nonacneigenic as opposed to the penta- and hexachloro-derivatives that produce very severe chloracne.

Safety Profile

Probably a poison. When heated to decomposition it emits highly toxic fumes of Cl-. See also CHLORINATED HYDROCARBONS, AROMATIC; and POLYCHLORINATED BIPHENYLS.

Carcinogenicity

Tetrachloronaphthalene was not mutagenic in the Salmonella Ames test.
