What is required for wetting agent extinguishers regarding maintenance?

Wetting agent extinguishers require annual complete maintenance to ensure their functionality and safety. This maintenance involves a thorough inspection of all components, including checking the pressure, examining hoses, and making sure that the extinguishing agent is within its expiration date. Regular complete maintenance is critical for wetting agent extinguishers, as they contain specialized agents that may degrade or settle over time. Annual maintenance not only verifies that the extinguisher is operational but also adheres to regulatory compliance and safety standards, thereby ensuring that it will perform effectively in an emergency situation.

Other maintenance schedules, such as monthly checks or 5-year internal inspections, serve specific functions but do not provide the comprehensive assessment that annual complete maintenance offers. While cleaning and operational checks may be necessary, they do not replace the need for the detailed annual evaluation that encompasses all aspects of the extinguisher's functionality.
