Description

Colorless liquid or gas (above 89 degrees F) with a mild, sweet, chloroform-like odor; [NIOSH]

Sources/Uses

Used as co-monomer in production of polymers for coatings, films, lacquer resins, and flame resistant binders in carpet backing; [ACGIH]

Comments

Liquid causes first degree burns on short exposure. [CHRIS] Similar to carbon tetrachloride, it is toxic to the liver and kidneys in animals exposed to high concentrations. [ACGIH] Possible frostbite from contact with liquid; [NIOSH] A skin, eye, and respiratory tract irritant; Inhalation of high concentrations can cause CNS depression; [ICSC]
