Understanding the Basics of Kitchen Fire Suppression

Posted on: April 9, 2013

A well installed and maintained kitchen fire suppression system is critical to keeping your restaurant or commercial food prep facility safe from fire. Two different NFPA codes lay out requirements for kitchen fire suppression systems:

NFPA 96: Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations

NFPA 17: Standard for Dry Chemical Extinguishing Systems

In between professional kitchen inspections, there are a couple of things you should pay special attention to:

1. Fuel Source Shutoff Valves

All commercial kitchens must have an electrical or mechanical valve to shut off the power to electric or gas sources while the kitchen fire suppression system is running. Because electricity and grease are the most common causes of commercial kitchen fires, fires in commercial kitchens, blocking them is critical to keeping a fire under control.

2. Nozzle Caps

It’s extremely important that you keep your kitchen fire suppression nozzles capped to prevent grease from building up inside and blocking the flow of extinguishing agent. Part of a kitchen fire suppression system inspection involves removing the caps to check and see if piping is clear of grease or other buildup, along with making sure the nozzles and caps are in place and in good shape. Finally, your technician will make sure your nozzles are aimed properly to extinguish a fire, if necessary.

3. Hood, Ductwork, and Ventilation

The exhaust hood located above the grill or stove move air and potential fuel outside of your facility. During an kitchen fire suppression system inspection, your fire protection technician will inspect the ductwork connected to your hood for any holes, blockages, or other issues that could compromise its performance.

4. Detector Links

Kitchen fire suppression systems are activated by detector links, which burn up in response to high levels of heat and release the extinguishing agent. Your fire protection technician will make sure all heat detector links are in the correct locations.

Kitchen fire suppression system maintenance is crucial to maintaining a healthy and safe environment in your restaurant or food prep facility. If you need commercial kitchen fire suppression system inspection in Maryland, Virginia or Washington, DC, call Guardian Fire Protection today.
