Which type of containers is approved for storing flammable liquids?

• A. Safety cans
• B. Glass bottles
• C. Plastic jugs
• D. Metal drums

Answer: (A)

Safety cans are the containers specifically designed and approved for storing flammable liquids. They are built with features that minimize ignition risk in a workspace: a self-closing, spring-loaded cap and pour spout, plus a flame-arresting screen in the vent. This design helps keep vapors contained, prevents spills, and reduces the chance that a nearby flame or spark will travel back into the can.

Glass bottles lack these safety features and are prone to breakage, which can cause spills and exposure to vapors. Plastic jugs may not be compatible with all flammable liquids and often don’t provide flame arresting ventilation or a reliable self-closing cap. Metal drums are intended for bulk storage, not portable, small-quantity use, and don’t offer the same portable safety features as standard safety cans.

So, for storing flammable liquids in many codes and practical settings, safety cans are the approved choice because of their design and built-in safety features.
