According to Seattle fire code 904.8 and 904.10, how often are gaseous extinguishing systems tested?

The frequency of testing for gaseous extinguishing systems, as specified in Seattle fire code sections 904.8 and 904.10, is annually. This requirement ensures that these systems are maintained in proper working order to provide effective fire protection when needed. Annual testing includes inspecting the system for any defects, confirming that it is fully operational, and assessing the integrity of components such as cylinders, piping, and nozzles. Regular annual testing helps to identify and rectify any issues that could compromise the system's effectiveness in the event of a fire, thereby ensuring safety in facilities protected by these systems.
