What happens if a DOT cylinder fails inspection?

If a Department of Transportation (DOT) cylinder fails inspection, the most significant consequence is that it cannot be filled. This is a safety measure designed to prevent the use of a potentially hazardous cylinder that may pose risks during transport or usage. The failure indicates that the cylinder does not meet the required safety standards, which may involve structural integrity or the ability to safely contain the gas under pressure. Continuing to fill a cylinder that has failed inspection could result in leaks or catastrophic failures.

While repair or re-inspection may be options for some cylinders, they cannot be utilized or filled until appropriate actions are taken to rectify the issues identified during the inspection. Thus, the emphasis is on ensuring safety, and not allowing a faulty cylinder to be refilled serves this vital purpose.
