How should gas cylinders be stored safely?

• A. Cylinders stored upright and secured, capped when not in use, segregated by gas type, away from heat/ignition sources, with regulators and hoses serviceable, and leaks checked; transport on a cylinder cart.
• B. Cylinders stored horizontally near heat sources.
• C. Cylinders stored in a locked cabinet away from people.
• D. Cylinders stored with regulators removed.

Answer: (A)

Gas cylinder safety hinges on secure, upright storage and valve protection. Cylinders should stand upright and be restrained so they cannot tip or be knocked over, which prevents valve damage and sudden releases of gas. Keeping the valve capped when not in use protects the valve stem from damage and contamination. Segregating cylinders by gas type helps prevent incompatible gases from coming into contact, reducing the risk of dangerous reactions or cross-contamination. Storing them away from heat and ignition sources minimizes the chance of pressure buildup, fires, or equipment failure. Ensuring regulators and hoses are in good condition and regularly checking for leaks keeps the entire gas delivery system reliable and safe. Transporting cylinders on a proper cylinder cart reduces handling hazards and the possibility of dropping or damaging them. The other options fail to provide this comprehensive protection: horizontal storage near heat sources increases tipping and heat risks; a locked cabinet alone doesn’t address valve protection, segregation, or leak checks; and removing regulators removes essential safety controls.
