Which hazmat type includes substances that promote combustion?

• A. Oxidizers
• B. Toxins
• C. Aerosols
• D. Flammable

Answer: (A)

Substances that promote combustion are oxidizers. They don’t have to burn themselves; they provide oxygen or create conditions that support burning, making a fire start more easily and spread faster when a fuel is present. That’s why oxidizers are the hazmat type that includes materials that promote combustion. Toxins affect living tissues, aerosols are dispersible droplets or propellants, and flammable materials ignite easily on their own; the defining trait here is supplying oxygen to support and intensify a fire.
