What happens if a test pressure gauge is found to be inaccurate?

When a test pressure gauge is found to be inaccurate, the appropriate action is to recalibrate or replace it. Ensuring that the pressure gauge provides accurate readings is crucial for the proper functioning of fire extinguishers. An inaccurate gauge can lead to misuse or failure to comply with safety regulations, which could endanger lives and property in the event of a fire.

Recalibration involves adjusting the gauge to reflect the correct pressure readings, while replacement is necessary if the gauge cannot be accurately restored. Regular checks and maintenance of testing equipment, including pressure gauges, are integral to maintaining safety standards and ensuring readiness in emergency situations. This practice aligns with the NFPA guidelines, which emphasize the importance of reliability and accuracy in fire safety equipment.
