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. In accordance with safety regulations such as those from the Department of Transportation (DOT), medical gas cylinders (like oxygen or nitrous oxide tanks) must undergo periodic hydrostatic testing to ensure structural integrity and safety under high pressure. Most steel and aluminum cylinders require testing every 5 years. However, certain cylinders that meet specific criteria for design and maintenance may have their testing interval extended to every 10 years. Therefore, the standard range for hydrostatic pressure testing is every 5 to 10 years.
