What Does Flammable Aerosol Mean?
A flammable aerosol is an aerosol that contains a component that is classified as flammable, whether it is liquid, gas or solid. There are two categories of flammable aerosols. A Category 1 flammable gas contains 85% or less flammable components. A Category 2 flammable gas contains less than 1% flammable components. These categories are also based upon technical criteria, such as the heat of combustion, ignition test distance, flame height and flame durability.
