Where should propane cylinders be kept with respect to ignition sources?

• A. In a location near heat sources.
• B. Inside a closed cabinet near a furnace.
• C. Under direct sun.
• D. Away from heat, sparks, open flames, and other ignition sources.

Answer: (D)

Storing propane cylinders away from ignition sources is about reducing the risk of a fire or explosion if gas leaks. Propane is a flammable gas kept under high pressure in the cylinder; heat from nearby ignition sources raises the pressure inside the cylinder and can cause leaks or venting. If leaked gas finds an ignition source—like sparks or flames—it can ignite quickly. So keeping cylinders away from heat, sparks, open flames, and other ignition sources minimizes both the chance of a leak becoming dangerous and the chance of any leaked gas igniting.

Choices that place cylinders near heat, in a closed cabinet near a furnace, or in direct sun expose them to heat that increases pressure and creates a hazardous environment, which is why they’re not suitable.
