What generic inspection is recommended for extinguishers that have undergone testing?

The recommended generic inspection for extinguishers that have undergone testing is the external inspection. This process involves checking the physical condition of the extinguisher, ensuring that there are no signs of damage, corrosion, or leaks, and that all parts are intact and functioning correctly. Conducting an external inspection is essential after testing to confirm that the extinguisher is still safe to use and ready for operational deployment.

While other types of inspections, such as functional evaluations or hydrostatic inspections, are also valuable in assessing the overall performance and integrity of a fire extinguisher, the external inspection serves as a fundamental step that ensures immediate visual assessment of the unit post-testing. Visual confirmation alone focuses primarily on the absence of obvious signs of damage, which is indeed a part of the external inspection process but lacks the comprehensive checks involved in the full external inspection.
