What is a potential hazard of Class 3 flammable and combustible liquids?

• A. They are never toxic.
• B. Container may rupture violently from heat/fire.
• C. They are inert and non-reactive.
• D. They require no PPE for handling.

Answer: (B)

Heating or exposure to fire can cause Class 3 flammable and combustible liquids to vent or rupture violently. The pressure inside a sealed container rises as the liquid warms and vapors expand, and many containers aren’t designed to withstand that rapid pressure increase, leading to a violent rupture that can spread burning fuel and worsen a fire. This is the most immediate hazard described for these liquids. They can also be toxic, and they are not inherently inert or non-reactive; PPE is typically needed when handling them, depending on the material.
