Cylinder refill logs should be completed after each fill on which cylinders?

• A. SCBA and oxygen cylinders
• B. Fire extinguishers
• C. Air-line cylinders
• D. CO2 detectors

Answer: (A)

Cylinder refill logs are kept for compressed gas cylinders used in respiratory protection to ensure safety and traceability of each fill. The cylinders that require a log after every fill are the portable breathing gas cylinders used in PPE—SCBA and oxygen cylinders—because they are carried by workers, must be filled to the correct pressure, and are subject to ongoing service, testing, and requalification. Recording the fill date, pressure, cylinder ID, and the person who performed the fill helps confirm the cylinder is safe to use, within its hydrostatic test interval, and ready for duty. Other items like fire extinguishers, air-line supply systems, or detectors are not managed in the same way within a respiratory protection program, so they do not require the same post-fill refill log.
