How often should oxygen cylinders be tested?

Oxygen cylinders must be tested every 5 years to ensure they are safe for use. This testing regimen is crucial because it assesses the integrity, functionality, and safety of the cylinder, which is essential for lifeguards and first responders who rely on oxygen for emergency situations.

Testing involves checking for structural integrity and any signs of wear or damage that could compromise the cylinder during use. By adhering to this 5-year testing guideline, organizations can maintain safety standards and ensure that the equipment performs effectively in emergencies.

The other timeframes presented in the options do not meet the safety protocols established for oxygen cylinder maintenance, potentially putting users at risk if the cylinders were to fail due to lack of adequate inspection.
