How often are DOT cylinders tested for recertification?

DOT cylinders are required to be tested for recertification every 5 years. This five-year interval is established by the Department of Transportation to ensure that the cylinders maintain their structural integrity and safety standards necessary for transportation. During this testing, the cylinders undergo rigorous inspections and pressure tests to identify any potential issues or weaknesses that could lead to failure during use.

The importance of this testing schedule lies in preventing accidents or hazardous incidents caused by cylinder failures, which can occur due to age, wear, or improper handling. Regular recertification ensures that the cylinders can safely contain gases at high pressures and are suitable for continued service in various applications, such as industrial and medical use. This systematic approach to safety ensures compliance with regulations that help protect both users and the general public.
