Which class is represented by the word 'Fire' in the mnemonic?

• A. Oxidizers/ Natural Peroxides
• B. Flammable/ Combustible Liquids
• C. Corrosive
• D. Poisonous/Infectious Substances

Answer: (B)

Fire cues the fire hazard category, which is Flammable/Combustible Liquids. These are materials that can ignite easily and start a fire when exposed to heat, sparks, or flames. The mnemonic uses the word “Fire” to remind you of this specific risk—the defining feature is flammability of liquids. The other hazards—oxidizers (which can fuel burning but aren’t themselves the fire label), corrosives, and poisonous/infectious substances—relate to different dangers, not the primary fire risk captured by the mnemonic.
