The letter 'E' following the date on the cylinder indicates requalification is required again within how many years of the marked date?

• A. 3 years
• B. 5 years
• C. 7 years
• D. 10 years

Answer: (B)

The date on a propane cylinder is paired with a letter that shows how long until the next requalification is due. The letter following the date indicates the requalification interval, and in this case it means five years. So the cylinder must be requalified again within five years of the marked date. Requalification checks, typically via hydrostatic testing, ensure the cylinder’s integrity and safety.
