Which document shows that a fire extinguisher is properly maintained?

The last inspection report is crucial in demonstrating that a fire extinguisher has been properly maintained. This document provides a record of the most recent evaluation of the extinguisher's condition, including any necessary repairs or replacements that may have been performed to ensure the extinguisher is fully operational. Regular inspections are essential for confirming adherence to safety standards and regulations, ensuring that the extinguisher will function effectively in an emergency situation.

While annual maintenance records can record ongoing maintenance and service, the last inspection report specifically verifies the current status of the extinguisher, reflecting any wear, pressure checks, and operational tests that have been conducted recently. This makes it the most direct evidence of proper maintenance for that fire extinguisher at a particular point in time.
