Highly flammable, odorless gas shipped as a liquid under pressure; [CAMEO]
Sources/Uses
Used as a chemical intermediate, refrigerant, and propellant; [HSDB]
Comments
Liquefied gas can cause frostbite; Can displace air and cause asphyxiation; Hydrogen fluoride fumes may be released in a fire; [CAMEO] Causes narcosis at high concentrations; [Hawley] Halogenated alkanes are highly lipophilic; they cross the blood-brain barrier to produce CNS depression.
