What are the three colors of tags used on a fire protection system?

In fire protection systems, the use of tags is critical for indicating the status and required maintenance of various components. The three colors of tags—White, Yellow, and Red—are standardized across many systems to convey specific meanings.

White tags are typically used to denote that a system has been inspected and is in proper working condition, serving as a reassurance that the system is ready to perform in an emergency. Yellow tags are often employed to indicate that a system is due for maintenance or inspection, alerting personnel that action is needed soon. Red tags usually signify that a part of the fire protection system is out of service or presents a significant issue that requires immediate attention.

This color-coding system helps ensure that visual communication is clear and effective, allowing firefighters and maintenance personnel to quickly assess the status of fire safety equipment. In contrast, the other color combinations presented do not align with the common standards observed in the industry for tagging fire protection systems.
