Which capacity requirement applies to a safety can for flammable liquids?

• A. Not more than five gallons
• B. Not more than ten gallons
• C. Not more than one gallon
• D. Not more than twenty gallons

Answer: (A)

Safety cans are designed to keep the amount of flammable liquid carried in a portable container small enough to limit fire risk and make handling safer. The standard five-gallon capacity strikes a balance between practicality and safety, giving enough volume for use while keeping spills, vapor buildup, and the consequences of accidents more manageable. If a safety can allowed more than five gallons, it would become a much bigger fire hazard and harder to handle or control in a workplace setting. When larger quantities are needed, different containment—such as larger drums with proper secondary containment and ventilation—is used instead.
