Poison by
intraperitoneal route. Moderately toxic by
inhalation, ingestion, and skin contact. A
severe skin and eye irritant. Flammable
liquid when exposed to heat or flame; can
react with oxidizing materials. To fight fire,
use alcohol foam, CO2, dry chemical. When
heated to decomposition it emits toxic
fumes of NOx. | [Toxicity]
