What is required on a red tag regarding the licensee?

The correct answer emphasizes the importance of having the licensee's signature included on the red tag. This requirement is crucial because the signature serves as a verification of the work performed and indicates that the licensee has reviewed and approved the details on the tag. It adds an element of accountability and ensures that there is a record that the licensed individual authorized the information presented.

Including only the licensee's name, certification level, or not including any specific information at all would not fulfill the necessary standards for documentation and verification. The signature signifies the agreement and acknowledgment of the details relating to the extinguishing equipment, reinforcing the professionalism and regulatory compliance expected in fire safety management.
