What location information is required on a red tag?

• A. Street name and city
• B. Building number and street
• C. System number only
• D. Building number, location, or system number

Answer: (D)

Red tags are there to quickly identify exactly which sprinkler system is out of service and where it sits so responders can locate and service it without delay. The information needed is an identifiable locator: the building number, a specific location inside the building, or the system number. Any one of these allows precise identification of the affected unit. Street names or city are irrelevant for a tag mounted in or near the equipment, and requiring more than one identifier isn’t necessary when a single clear locator will do. So, including building number, location, or system number ensures the tag clearly points to the correct system.
