What is the consequence of not tagging out and depressurizing a high-pressure air system before performing maintenance?

Failing to tag out and depressurize a high-pressure air system before performing maintenance poses significant risks, primarily leading to potential injury or equipment damage. When maintenance work is conducted on a system that is still pressurized or energized, the sudden release of high-pressure air can cause serious harm to personnel, including injury from flying debris or sudden air blasts. Furthermore, such actions can result in substantial damage to equipment due to uncontrolled releases that can affect components or undermine the integrity of the system. Properly tagging out and depressurizing ensures safety protocols are followed, reducing risks and creating a safer working environment.
