• A. Upright, capped when not in use, secured to prevent tipping, in a well-ventilated area away from heat sources.
• B. Lying on their side near a heat source.
• C. Stored in a closed, unventilated cabinet.
• D. Stored outdoors with no ventilation.

Answer: (B)

Store propane cylinders upright, capped when not in use, secured to prevent tipping, and in a well-ventilated area away from heat sources. Keeping them upright ensures the valve and safety devices stay in their proper position and helps prevent liquid propane from entering the regulator if there’s a leak. The cap protects the valve from damage and dirt when the cylinder isn’t being used. Securing the cylinder prevents it from rolling or being knocked over, which could damage the valve and cause a leak. Good ventilation is essential because propane is heavier than air and will collect near the ground if it leaks, so any gas can disperse rather than accumulate and reach ignition sources. Storing on its side, near a heat source, in a closed or unventilated space, or outdoors without ventilation all create conditions where leaks can accumulate, damage to the valve can occur, and ignition risk increases.
