Fire Suppression Nozzles Clogged or Missing

Grease and carbon buildup from cooking operations is the leading cause of clogged suppression nozzles, particularly above fryers, griddles, and char-broilers. Nozzles that lack protective caps accumulate grease faster and can become fully blocked between service intervals. Missing nozzles result from accidental damage during hood cleaning, equipment repositioning, or unauthorized tampering. Systems that have not been inspected on the required semi-annual schedule are most likely to have undetected blockages.

A clogged or missing nozzle creates a dead zone in your fire suppression coverage, meaning the system will not extinguish a fire in that area even if it activates. This puts your staff, building, and neighboring businesses at serious risk. Insurance carriers can deny fire-related claims if the suppression system is found to be non-functional due to deferred maintenance. A failed inspection triggered by this condition can result in an immediate shutdown order from the fire marshal.
