Which color is used to identify a container intended for flammable liquids?

• A. Red
• B. Blue
• C. Green
• D. Yellow

Answer: (A)

Colors on hazard containers are used for quick recognition of the type of danger. Red is used to identify flammable liquids because it’s closely associated with fire risk. Seeing a red container signals you to keep it away from heat, sparks, and open flames and to follow safe handling practices, like proper grounding and using approved storage. Other colors have different meanings in standard color-coding schemes—blue is often linked to health hazards, yellow to reactivity or instability—so they wouldn’t indicate flammable liquids.
