Which statement about safety cans for flammable liquids is true?

• A. They must be vented during operation.
• B. They are designed for unlimited capacity.
• C. They must be kept away from ignition sources.
• D. They are designed to hold up to five gallons maximum.

Answer: (D)

Safety cans are designed with a limited capacity to reduce the hazard when handling flammable liquids. The typical maximum size is five gallons, which keeps the amount of material manageable and minimizes the risk of large spills or intense vapors. These cans are built with features like a self-closing lid and flame-arresting components to limit ignition from sparks or flames. Venting during operation isn’t a universal requirement for all safety cans, and unlimited capacity would defeat their safety purpose. While it’s standard safety practice to keep flammable liquids away from ignition sources, that applies broadly and isn’t a defining specification of the can’s design. Therefore, the true statement is that safety cans are designed to hold up to five gallons maximum.
