Which certification would cover the hydrostatic testing of extinguishers?

The certification that covers the hydrostatic testing of extinguishers is the FEX-3. This certification specifically includes the necessary knowledge and skills related to the safe and effective inspection, maintenance, and testing of fire extinguishers, which encompasses hydrostatic testing. Hydrostatic testing is a critical procedure to ensure that fire extinguishers can withstand the pressures they will encounter during actual use, verifying their integrity and safety.

The emphasis of FEX-3 on hands-on training and practical application enables professionals to understand the regulations and procedures associated with hydrostatic testing, including how to conduct the tests safely and which standards must be met. This makes it essential for anyone involved in the maintenance and inspection of fire extinguishers to be certified under this program to ensure compliance with safety regulations. The other certifications mentioned may focus on different aspects of fire safety training and do not specifically address the testing of extinguishers in this context.
