What registration information is required on a red tag?

• A. Date of last inspection
• B. Firm's certificate of registration number
• C. Owner's telephone number
• D. License numbers

Answer: (B)

Red tags are meant to show who is responsible for the work and that the company is properly authorized to perform fire protection system tasks. The key registration detail on the tag is the firm’s certificate of registration number. This number uniquely identifies the company that did the work, allowing anyone reviewing the tag to verify the firm’s credentials and accountability. Other items like a personal phone number or generic license numbers don’t provide that same clear link to the registered company, and while dates of inspection are important for records, they don’t serve as the registration identifier.
