Medical gas cylinders undergo pressure testing how often? Select one: a. every 1 to 3 years, b. every 3 to 5 years, c. every 5 to 10 years, d. every 10 to 15 years

Answer

The correct answer is c (every 5 to 10 years). According to Department of Transportation (DOT) and National Fire Protection Association (NFPA) regulations, most medical gas cylinders are required to undergo hydrostatic pressure testing at intervals of either 5 or 10 years to ensure structural integrity and safety. Steel cylinders typically require testing every 5 years, while those meeting certain specific criteria (marked with a star) can be tested every 10 years. Therefore, the frequency range is generally categorized as every 5 to 10 years.
