What is the significance of a red tag on a fire sprinkler system?

A red tag on a fire sprinkler system serves a critical function in identifying the operational status of that system. Specifically, it indicates that the system is out of service due to repairs or maintenance being performed. This is vital for safety and awareness, as it alerts personnel that the fire protection system is not functioning as intended and that there is an increased risk in the event of a fire.

Recognizing a red tag helps ensure that firefighters, building management, and maintenance personnel all understand the current state of the system and can take appropriate precautions until the system has been restored to operational status. This clear communication is essential for maintaining safety standards in any building equipped with fire suppression systems.
