How often must DOT/TC propane cylinders be recertified?

• A. 5 years
• B. 10 years
• C. 12 years
• D. 15 years

Answer: (B)

The correct answer is based on the regulations set for the periodic inspection and recertification of propane cylinders, which follow standards outlined by the Department of Transportation (DOT) in the United States and Transport Canada (TC) in Canada. According to these guidelines, use of standard propane cylinders requires that they be requalified or recertified every ten years from the date of their manufacture or last requalification. This recertification process is crucial to ensure the safety and integrity of the cylinders, as they can experience wear and tear, corrosion, or damage over time that could compromise their ability to safely contain propane under pressure. By adhering to this ten-year requirement, operators can maintain safety standards and comply with federal and provincial regulations regarding the transport and storage of propane. In contrast, the other time frames provided in the choices do not align with the current regulatory requirements; five years, twelve years, and fifteen years all exceed or fall short of the established ten-year recertification interval. Therefore, the ten-year period stands as the appropriate recertification frequency for DOT/TC propane cylinders.
