Triethylene glycol monomethyl ether Safety Profile

Mildly toxic by ingestion and skin contact. A skin and eye irritant. Many glycol ether compounds have dangerous human reproductive effects. Combustible when exposed to heat or flame. To fight fire, use alcohol foam, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also GLYCOL ETHERS.
