What is the main purpose of a fire extinguisher tag?

The main purpose of a fire extinguisher tag is to record the service history of the extinguisher. This tag serves as a crucial tool for ensuring that the fire extinguisher is regularly inspected, maintained, and serviced in accordance with safety regulations and standards. It typically contains important information such as the date of the last inspection, any maintenance performed, and the responsible service technician's details. Maintaining a proper service history is vital for guaranteeing the effectiveness of the extinguisher in an emergency, as it ensures that the device is ready for use and meets safety requirements.

Other options, such as highlighting the extinguisher color or indicating the make and model, do not primarily define the function of the tag. While such information may be displayed for awareness and inventory purposes, the critical role of the tag is to track maintenance and service records effectively. Additionally, while providing the extinguisher's location is important, it is not the primary function of the tag itself. Hence, the service history aspect takes precedence in terms of safety and compliance.
