“Level 3 aerosol products.” Those with a total chemical heat of combustion that is greater than 13,000 Btu/lb (30 kJ/g).
“Aerosol container.” A metal can, or a glass or plastic bottle designed to dispense an aerosol. Metal cans shall be limited to a maximum size of 33.8 fluid ounces (1000 ml). Glass or plastic bottles shall be limited to a maximum size of 4 fluid ounces (118 ml).
“Aerosol warehouse.” A building used for warehousing aerosol products.
“Propellant.” The liquefied or compressed gas in an aerosol container that expels the contents from an aerosol container when the valve is actuated. A propellant is considered flammable if it forms a flammable mixture with air, or if a flame is self-propagating in a mixture with air.
