When using compressed air for cleaning, it should be rated at less than what pressure?

When using compressed air for cleaning, the standard recommends that it should be rated at less than 30 PSI to ensure safety and effectiveness. Using air at or below this pressure helps prevent the risk of injury to personnel from high-pressure streams of air, which can potentially drive debris into the skin or eyes, causing injury.

Additionally, keeping the pressure under 30 PSI minimizes the risk of damaging sensitive components in the fire protection systems during cleaning. The threshold of 30 PSI has been established as a safe limit, allowing for effective cleaning without compromising safety or equipment integrity. This guideline promotes safe practices in the maintenance of water-based fire protection systems, aligning with NFPA standards and enhancing overall workplace safety.
