How long after a manufacture date may a DOT (ICC) Steel or Aluminum cylinder be used without recertification?

A DOT (ICC) Steel or Aluminum cylinder can be used without recertification for a maximum of 12 years after the manufacturer’s date. This timeframe is established by regulations to ensure safety and reliability for gas cylinders in use. Every gas cylinder has a date stamped on it that indicates its manufacture, which is critical for determining its recertification schedule.

Once the initial 12-year period has elapsed, the cylinder must undergo a thorough inspection and recertification process to ensure that it remains safe for continued use. The recertification involves checking for any physical damage, corrosion, leaks, or any other issues that may compromise the integrity of the cylinder. This system helps ensure that cylinders are safe to handle and use in various applications, thus minimizing risks associated with gas leakage or cylinder failure.
