Which of the following is a valid property of containers used for flammable liquids?

• A. are red in color
• B. are approved
• C. have two handles
• D. are clear

Answer: (B)

Containers used for flammable liquids must be approved. Approval means the container has been tested and certified by recognized safety authorities to meet standards for construction, leakage resistance, venting or closures, and material compatibility with flammable liquids. This certification is what ensures the container will perform safely during storage and handling, helping prevent leaks, spills, and vapor hazards. Color, number of handles, or being clear do not by themselves indicate safety approval, so they’re not reliable indicators of proper compliance.
