Cylinders may not be filled if they are past their ____ date.

Cylinders may not be filled if they are past their ____ date.

• A. Manufacture
• B. Re-qualification
• C. Last service
• D. Last hydrostatic test

Answer: (B)

Cylinders may be filled only up to the date when they must be requalified. This requalification date marks the deadline for the cylinder to undergo a new inspection and hydrostatic test to prove it’s still safe to use. After that date, the cylinder isn’t allowed to be filled until it has been requalified. The manufacture date just shows when the cylinder was made, not its current safety status. The last service date and the most recent hydrostatic test are related to maintenance, but the mandatory limit for filling is the requalification date.
