How often must open-circuit SCUBA cylinders be visually inspected?

Open-circuit SCUBA cylinders must be visually inspected every 6 months to ensure their integrity and safety for diving operations. This regular inspection is critical because it allows for early detection of any issues, such as corrosion, deformation, or faulty valves, that could compromise the cylinder's function.

Routine inspections also help to maintain compliance with safety standards set by organizations such as the Occupational Safety and Health Administration (OSHA) and the Department of Transportation (DOT). By adhering to this frequent inspection schedule, divers can minimize the risk of equipment failure underwater, enhancing both their safety and that of their dive companions.

While cylinders may also be checked for initial condition and during refilling processes, these checks do not replace the necessity for the comprehensive visual inspection every 6 months. Regular visual inspections help to ensure that all components of the cylinder are in good condition, and any potential issues can be addressed proactively.
