When should a service tag not be attached?

A service tag should not be attached until the impairments are corrected because the purpose of the tag is to communicate important information about the status of the fire protection equipment. If there are impairments that could hinder the effectiveness of the equipment, marking it as serviced with a tag would give a misleading impression that it is safe and fully operational.

The service tag serves to inform users and inspectors about the condition of the equipment and any actions taken or required. Therefore, it's crucial that no tag is affixed until all issues are resolved to ensure that the documentation accurately reflects the state of the fire protection system. This practice helps to maintain safety standards and compliance with regulations regarding fire safety equipment.
