Reported in EPA TSCA Inventory.

Isobutyl vinyl ether Safety Profile

Very mildly toxic by ingestion, inhalation, and skin contact. A very dangerous fire hazard when exposed to heat, flame, oxidizers. Severe explosion hazard when exposed to sparks or open flame. Can react vigorously with oxidizing materials. When heated to decomposition it emits acrid smoke and fumes. To fight fire, use alcohol foam, CO2, dry chemical. See also ETHERS.
Hazard Codes: FlammableF,IrritantXi
Risk Statements: 11-38
R11:Highly flammable.
