Methyl bromide is a colorless, highly volatile gas that exists as a liquid below 3.6°C. It is heavier than air. Methyl bromide is nonflammable over a wide range of concentrations in air, and poses practically no fire hazard. These physical properties result in excellent penetration properties and make it a good fumigant.Web
