Leaks, cracks, or bulging are often discovered during which type of cylinder inspection?

• A. Pre-fill cylinder inspection
• B. Post-fill cylinder inspection
• C. Annual inspection
• D. Emergency inspection

Answer: (A)

Before filling, cylinders are checked to confirm they are safe to fill. Leaks, cracks, or bulging are clear signs of compromised integrity, and identifying them before any fill prevents dangerous conditions from developing once the cylinder is pressurized. If such defects are found, the cylinder isn’t filled and is taken out of service.

Post-fill inspections look for leaks after filling, which is important but doesn’t prevent the hazard during the fill itself. Annual inspections are periodic safety checks for wear and overall condition, not specifically the pre-fill readiness. Emergency inspections happen in urgent situations and aren’t routine checks.
