What information is required on a service tag for fire extinguishers?

The correct answer highlights essential information necessary for compliance with regulations and for tracking the maintenance of fire extinguishers. A service tag for fire extinguishers must include critical details that indicate when the extinguisher was last serviced, who performed the service, and their certification status. Such information typically encompasses the name of the technician and the date of service.

Including the owner's social security number and purchase price is not standard practice and does not serve a clear safety or regulatory purpose. The service tag should focus on operational and safety-related information rather than personal or financial details, making it less relevant in a fire safety context. The location of use and the owner's business license, while helpful in specific scenarios, do not directly pertain to the service tag's requirements. Similarly, the name of the manufacturer and model number might be useful but are generally less critical than the service details.

Thus, for fire safety compliance, the focus should be on service-related information that assures the extinguisher is in operational condition and has been maintained properly.
