Which statement about storage and handling of propane cylinders is true?

• A. Cylinders must be upright and secured away from heat and ignition sources.
• B. Cylinders stored near heat sources.
• C. Cylinders stored in unventilated spaces.
• D. Cylinders do not require protection from impact.

Answer: (A)

Propane cylinders must be stored upright, secured so they can’t tip, and kept away from heat and ignition sources. Keeping cylinders upright helps the valve and safety devices work properly and prevents liquid propane from pushing back into the valve. Securing them stops tipping, which can damage the valve or cause leaks. Being away from heat reduces the chance of increased pressure inside the cylinder and lowers the risk of ignition if a leak occurs. Propane is heavier than air, so good ventilation is also important to prevent gas from pooling if a leak happens.

Storing cylinders near heat sources, in unventilated spaces, or without protection from impact all raise the risk of fire, explosion, or dangerous gas release.
