In all cases call a physician. Above flash point, vapor-air mixtures are explosive within flammable limits noted above. Water spray, dry chemical, alcohol foam, or carbon dioxide. Use water with caution as material reacts with water. Use water spray to blanket fire, cool fire exposed containers, and to flush non-ignited spills or vapors away from fire.
Vapors can flow along surfaces to distant ignition source and flash back.
Stable under ordinary conditions of use and storage. Heat will contribute to instability. When heated to decomposition, it emits toxic fumes such as acetic acid and carbon monoxide. This substance does not polymerize. Water, steam, oxidizing materials, alcohols, or amines may cause violent reaction.
