How often does a kitchen fire suppression system need inspection?

At each semiannual visit

• Detection line and fusible links checked, and links replaced on the schedule the standard sets
• Nozzles checked for aim, blockage and grease caps
• Agent tank and cartridge checked
• Manual pull station and automatic gas or power shut-off tested
• A dated service tag left on the system

Between visits

• Keep the pull station clear and visible
• Don't move cooking equipment out from under its nozzles
• Keep your Class K extinguisher mounted near the cook line and inspected

Call sooner when

• The system discharges — even partly — it needs service and recharge before you cook again
• You add, move or swap cooking appliances under the hood
• The service tag is out of date

Who decides

Your local fire marshal or authority having jurisdiction (AHJ) decides what applies to your kitchen — check with them and your insurer.
