Commercial kitchens are one of the highest fire-risk environments in any building. Between open flames, hot oil, and grease buildup in the exhaust system, a single spark can turn into a serious fire in seconds. That’s why kitchen hood suppression systems — and the inspections that keep them working — are non-negotiable for any restaurant, cafeteria, or food service operation.
A standard fire extinguisher isn’t designed to handle a grease fire on its own, and water can actually make a grease fire worse. Kitchen hood suppression systems solve this by installing a dedicated network of nozzles above the cooking line and inside the exhaust hood, connected to a tank of wet chemical agent. When triggered — either automatically by heat or manually with a pull station — the system floods the cooking surfaces and shuts off fuel or gas to the appliances, cutting off the fire’s source at the same time it’s suppressing the flames.
A+ Fire Protection Services got its start as a commercial kitchen exhaust cleaning company back in 2002, and kitchen hood systems remain one of our core specialties today. We work with Buckeye and Pyro-Chem systems, and our services cover the full lifecycle of a hood suppression system:
A kitchen hood suppression system doesn’t operate in isolation. Most commercial kitchens are also required to keep a properly rated portable fire extinguisher — typically a K Class unit — within reach of the cooking line for smaller flare-ups the suppression system isn’t designed to handle. And because a kitchen fire can trigger an evacuation, your emergency exit lighting needs to be functioning and tested on schedule so staff and customers can get out safely if the worst happens.
Handling all three — hood suppression, extinguishers, and exit lighting — through one provider means your inspection schedules stay coordinated instead of running on three different calendars.
Local fire departments and insurance inspectors typically check for:
Missing any of these during an inspection can mean fines, or in some cases, an order to close the kitchen until the issue is resolved.
Grease accumulates on hood surfaces and inside ductwork over time, even with regular cleaning. That buildup increases fuel for a fire and can also interfere with how well a suppression system covers the cooking line. Routine service inspections catch nozzle misalignment, clogged lines, and low agent levels before they become a problem during an actual fire — not after.
How often does a kitchen hood suppression system need to be inspected? Most jurisdictions require a professional inspection every six months, though local fire codes can vary. A licensed technician can confirm the exact schedule required for your specific system and location.
Do you provide estimates for new hood system installations or repairs? Yes. A+ Fire Protection Services provides clear, transparent estimates for all services, including multi-unit discounts for restaurant groups with more than one location.
Can you handle my entire fire protection system, not just the kitchen hood? Absolutely. A+ Fire Protection Services manages fire extinguishers, sprinklers, alarms, pumps, fire doors, backflow monitoring, and emergency lighting in addition to kitchen hood systems — learn more about our full history and services.
Are your technicians certified and trained? Yes, our team is licensed and trained, with nearly two decades of combined experience meeting NFPA codes and local regulations.
