Overview
Every commercial kitchen with open-flame equipment, fryers, or grills is required by NFPA 96 to have a listed kitchen hood suppression system. These systems must be inspected every six months by a licensed contractor — not annually like most water-based systems. Grease accumulation in exhaust hoods and ductwork is the leading cause of restaurant fires, and inspection deficiencies can result in fines, forced closure, or voided insurance. Contractors who specialize in food service suppression understand the unique demands of high-grease-load environments, ansul system service, and local health department coordination.

FAQ
Common Questions — Restaurants & Food Service
How often does a restaurant kitchen hood suppression system need to be inspected? ▾
Every six months, per NFPA 96. This is twice as frequent as most other commercial suppression systems. The six-month cycle applies regardless of whether the equipment is in heavy or light use.
Can the same contractor inspect both the kitchen hood and the building sprinkler system? ▾
Often yes, but not always. Kitchen hood inspections require manufacturer-specific certification (e.g., Ansul R-102, Amerex KP, Kidde Pyrochem). Confirm your contractor holds the appropriate factory certification for your specific suppression system brand before scheduling.
What happens if we change our cooking equipment after the last inspection? ▾
NFPA 96 requires the suppression system to be re-evaluated and potentially redesigned whenever cooking equipment is added, moved, or replaced. The system nozzle coverage must match the current equipment configuration — an inspection tag for the old layout does not cover the new one.
What does a failed kitchen hood inspection mean for our restaurant? ▾
A failed inspection typically results in a written deficiency report with a correction deadline. Depending on the severity, your local AHJ or health department may require you to cease cooking operations until deficiencies are corrected. Most jurisdictions require a re-inspection certificate before re-opening.
Informational purposes only. Regulatory requirements vary by jurisdiction and are subject to change. NFPA standards are adopted on different schedules by different states and may be amended locally. Always verify current requirements with your local Authority Having Jurisdiction (AHJ) and a licensed fire protection contractor before scheduling work.
