At what psi should an oxygen tank be replaced?

An oxygen tank should typically be replaced when it reaches a pressure of 1,200 psi. This standard is in place to ensure that there is sufficient oxygen available for emergencies. When using oxygen tanks, it's crucial to maintain a level that allows for adequate supply during a rescue situation, where every moment counts. At 1,200 psi, the tank is considered to be nearing the lower range of what is deemed safe and effective for use.

The selection of this pressure is based on the understanding that a tank should have enough contents to provide necessary care without risking running out in critical moments. Maintaining an awareness of oxygen levels ensures that lifeguards and first responders can operate effectively and safely. Higher pressure levels are typically more than necessary for standard usage, but approaching or dropping below 1,200 psi can limit the capacity to respond effectively in an emergency.
