What information should be included on a service label for fire extinguishers?

The information that should be included on a service label for fire extinguishers is essential for ensuring that these life-saving devices are maintained properly. The correct choice contains several crucial elements: a waterproof label that is sized appropriately, the month and year the inspection was performed, the name of the person who conducted the service, and the name of the agency that performed the work.

Including the month and year is vital as it indicates the last inspection date and helps determine if the extinguisher is due for its next service, which is important for reliability in emergencies. The name of the person performing the work provides accountability and allows for tracking of service history, while the agency's name ensures that the service was rendered by a certified and reputable organization.

This detailed record-keeping helps fire safety personnel quickly assess the condition and service history of the extinguisher, facilitating compliance with regulations and ensuring optimal readiness. In contrast, other choices highlight less relevant or crucial aspects of fire extinguisher service labels.
