What is required for hydrostatic testing of portable extinguishers?

The requirement for hydrostatic testing of portable extinguishers includes having a hydrostatic test log and calibrated gauges. Hydrostatic testing is a critical process that determines whether a fire extinguisher can withstand pressures higher than those it will typically encounter during use.

The hydrostatic test log is essential because it maintains a record of the testing conducted, ensuring that extinguishers are tested at the required intervals and facilitating compliance with safety regulations. Calibrated gauges are also crucial as they provide accurate measurements of pressure during the testing process, ensuring that the results are reliable and that the extinguisher meets safety standards.

In the context of this process, while hand tools and labels, a technician’s approval, or a simple pressure gauge may be useful, they do not represent the essential components required for hydrostatic testing specifically. The combination of a well-documented test log and precise, calibrated equipment directly supports proper testing and safety compliance.
