Poison by ingestion. A skin irritant. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx. See also 2,4-DINITROTOLUENE.
OSHA PEL: TWA 1.5 mg/m3 (skin)
NIOSH REL: (Dinitrotoluene) Reduce to lowest level
2,6-Dinitrotoluene (CAS NO.606-20-2) is sensitive to heat. it may explode when exposed to heat or flame. 2,6-Dinitrotoluene can be detonated only by a very strong initiator. And 2,6-Dinitrotoluene is incompatible with strong oxidizers. Besides, it is also incompatible with caustics and metals such as tin and zinc. It may react with reducing agents. 2,6-Dinitrotoluene will attack some forms of plastics, rubber and coatings.
