Which of the following actions should NOT be taken when conducting an internal examination of a fire extinguisher?

During an internal examination of a fire extinguisher, it is essential to analyze all aspects that ensure its proper function and safety. Leaving the extinguisher in its current location is inappropriate because an internal examination typically requires the technician to have full access to the extinguisher without any obstructions or hazards that might complicate the inspection process.

Removing the extinguisher from service during inspection allows for a thorough assessment without risking a false sense of security about the extinguisher's readiness. Testing the extinguishing agent's effectiveness and checking the expelling means are critical actions that help verify that the extinguisher will function properly in an emergency. However, these processes cannot be adequately carried out if the extinguisher remains in its location, where access could be hindered and the examination could be incomplete.
