What is the safe handling practice for compressed gas cylinders?

• A. Store upright and secured, cap valves when not in use, segregate by hazard, use proper trolleys, and never roll or drop cylinders.
• B. Keep valves open for quick release.
• C. Roll cylinders to move them.
• D. Store upright and secured.

Answer: (A)

Handling compressed gas cylinders safely means controlling how they are stored and moved to prevent leaks, valve damage, and injuries. Storing them upright and secured keeps cylinders from tipping and damaging their valves. Putting valve protection caps on when not in use protects the valve from impact. Segregating cylinders by hazard reduces the risk of incompatible gases reacting or causing dangerous conditions. Using proper trolleys to move cylinders supports safe handling and prevents rollaways or strains, and never rolling or dropping cylinders avoids physical damage and accidents. Leaving valves open is dangerous because it risks unintended gas release; rolling cylinders is unsafe for the same reason and can lead to injury; and storing upright alone misses important protections like valve caps, hazard segregation, and proper movement equipment.
