Do not wait for your next scheduled inspection. Contact a certified fire suppression service provider within 24 to 48 hours to inspect all nozzles, clear any blockages, replace missing or damaged components, and verify full system coverage. Document the issue and the service call in your maintenance log in case of any subsequent inspection or insurance inquiry.
What's causing it
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.
What happens if you wait
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.
NFPA 96 requires semi-annual inspection of all suppression system components including nozzles, and LA County Fire Department inspectors will cite missing or obstructed nozzles as a violation requiring immediate corrective action.
