Ignitable Wastes

Ignitable wastes¹ are wastes that can easily catch on fire and sustain combustion. Wastes are considered ignitable when they exhibit any of the following characteristics:

• Liquid, other than an aqueous solution containing less than 24% alcohol by volume, with a flashpoint less than 140°F (60°C) as determined by flashpoint testing².
• A non-liquid  under standard temperature and pressure (STP), is capable of causing fire through friction, absorption of moisture or spontaneous chemical changes and, when ignited, burns so vigorously and persistently that it creates a hazard. Non-liquids are more difficult to test.
• Ignitable compressed gas³
• Oxidizer⁴

The ignitable hazardous waste characteristics used in California are exactly the same as in the federal hazardous waste classification system.

Ignitable wastes are listed under RCRA waste code D001.
