What is required for a stainless steel extinguisher to be compliant?

For a stainless steel extinguisher to be compliant, it is necessary to conduct an annual conductivity test. This is crucial because stainless steel extinguishers require specific maintenance to ensure their operational effectiveness, particularly in environments that may lead to corrosion or wear over time. The conductivity test verifies that the extinguishing agent can properly function when deployed, ensuring safety and compliance with safety regulations.

While regular maintenance practices, such as inspections and pressure gauge checks, are vital for the overall upkeep of fire extinguishers, the annual conductivity test specifically addresses the integrity of the extinguishing agent within stainless steel containers. Therefore, this test is a key component of compliance for these types of extinguishers.
