Long before A+ Fire Protection Services became a full-service fire protection company, this business started as a kitchen exhaust cleaning operation. That history matters, because it means kitchen hood and exhaust systems aren’t a side service we picked up later, they’re where we started, and we’ve watched firsthand how much grease buildup contributes to commercial kitchen fires when it isn’t addressed on schedule.
Why the Hood System Carries More Risk Than People Realize
Every commercial kitchen pulls grease-laden vapor up through its hood and exhaust system, and that vapor doesn’t just disappear, it cools and collects on every surface it touches along the way. A duct lined with accumulated grease is essentially a fuel source sitting directly above your cooking equipment. The suppression system mounted in the hood is your last line of defense if a fire does start, but it can only do its job if the surrounding system hasn’t become a hazard in its own right.
How Often Cleaning Is Actually Needed
Cleaning frequency depends heavily on cooking volume and type. High-volume kitchens, including those running 24 hours or cooking with solid fuel, typically need the most frequent attention, while lower-volume operations can often extend the interval safely. The deciding factor isn’t a calendar date, it’s how quickly grease is actually accumulating in your specific system, which is exactly why a one-size-fits-all schedule doesn’t work for every kitchen.
Suppression System Inspections Are a Separate Requirement
The fixed suppression system above your cooking line, the part that automatically discharges a fire-suppressing agent and shuts off fuel to your equipment, needs its own regular inspection separate from hood and duct cleaning. These inspections confirm the system will actually activate correctly and discharge the right agent to the right area if it’s ever needed, which is a very different check than removing grease buildup from the ductwork.
What This Means for Compliance
Current fire codes require regular testing and inspection on all types of fire protection systems, and commercial kitchens carry some of the most specific requirements of any property type, given how directly grease and cooking fires are tied to fire risk. We stay on top of these requirements so our clients don’t have to track them themselves, and we partner with platforms like IROL and Compliance Engine to help streamline that documentation for the properties we serve.
A Kitchen’s Fire Protection Doesn’t Stop at the Hood
Hood and exhaust service is one critical piece of a commercial kitchen’s overall fire protection, but it works alongside the fire extinguishers, sprinkler systems, and emergency lighting installed throughout the rest of the property. A kitchen with a perfectly maintained hood system but expired extinguisher tags, or working sprinklers but no tested emergency lighting along the exit path, still has real gaps. We think about these systems together rather than as separate boxes to check.
