Class 3 includes which type of liquids?

• A. Gases
• B. Flammable and combustible liquids
• C. Solids
• D. Radioactive liquids

Answer: (B)

Class 3 is about liquids that can ignite, so it covers flammable and combustible liquids. This fire-hazard category groups liquids by how easily their vapors can ignite, which is the key factor in risk assessment and response. Flammable liquids have lower flash points and can ignite at relatively low temperatures, while combustible liquids have higher flash points but still pose a serious fire risk when spilled or heated. In a correctional facility, knowing this helps with safe storage, preventing ignition sources nearby, and using proper containment and spill cleanup procedures. Gases are categorized separately because their hazard comes from vapors that can disperse and form explosive mixtures, not from being liquids. Solids aren’t liquids, and radioactive liquids carry a different hazard due to radioactivity.
