How often are cylinders to be examined to ensure sound condition?

• A. Weekly
• B. Quarterly
• C. Biannually
• D. Monthly

Answer: (D)

Regular visual examination of medical gas cylinders is essential to confirm they are in sound condition and safe to use. This is typically done on a monthly basis in healthcare stores because it provides a practical, timely check without overburdening staff.

During the monthly check, handlers look for signs of damage or deterioration that could cause leaks or failure in service. This includes dents, bulges, corrosion, or other physical damage to the cylinder, as well as issues with the valve, valve cap, or thread, which could affect safe connections. Labels and colour coding should be intact and legible, and the cylinder should be stored upright, secured, and kept away from heat or flammable sources. If any leak or defect is detected, the cylinder is taken out of service and inspected or repaired by qualified personnel.

Hydrostatic tests and re-certification occur on a much longer cycle (several years) and are separate from the routine monthly check. Monthly examinations focus on maintaining day-to-day safety and readiness, catching problems before use.
