What is required of the pressure gauges in the sprinkler system?

The requirement for pressure gauges in the sprinkler system to be calibrated annually is essential to ensure their accuracy. Regular calibration helps maintain operational integrity, allowing personnel to rely on the readings for effective monitoring of the system's performance.

Visibility is also critical; pressure gauges need to be visible from a distance so that they can be easily monitored without having to approach the system directly. This feature is particularly important in emergency situations where quick assessments are needed to determine if the system is functional.

Operational and functional gauges are necessary for the sprinkler system to perform its critical role in fire safety. If the gauges are not operational, it could lead to undetected issues within the system that might compromise the ship’s safety.

Therefore, the requirement that encompasses calibration, visibility, and operational functionality collectively contributes to the effective and safe operation of the sprinkler system, affirming that all the mentioned criteria must be met.
