Most home fires are caused by cooking. According to the NFPA (National Fire Protection Association), an average of 172,900 home fires happen every year. These fires result in an average of 4,820 reported fire injuries, 550 deaths, and more than $1 billion in property damage annually.
Thankfully, kitchen fire suppression systems help. They’re the first line of defense against kitchen fires. Plus, you must protect your family from kitchen fires. While you can use many types of fire extinguishers to put out fires, prevention is always better than cure.
If you’re new to kitchen fire suppression systems or are looking to install one, this guide will help you learn how they work. We’ll start with an overview of kitchen fire suppression systems, their basic components, and how they keep you safe.
What is a Kitchen Fire Suppression System?
Your kitchen is your house’s most at-risk area when it comes to fires. Contrary to popular belief, water makes a grease fire worse. Hence, you need a fire suppression system in your kitchen.
A kitchen fire suppression system protects you against kitchen fires. It acts as the first line of defense against fire in residential and commercial kitchens. Experts usually install this system in the exhaust hood.
In particular, the said fire safety system prevents kitchen fires from spreading to other areas of your house or restaurant. If a kitchen fire occurs, you’ll feel relieved knowing that the flames will be contained.
Hence, a kitchen fire suppression system provides a safe and efficient way to easily extinguish kitchen fires. It puts out the source of most kitchen fires— the cooking surface.
It’s vital that you have a fire suppression system in your kitchen. It should also be updated, so it’ll work as planned.
Most kitchen fire suppression systems connect to your kitchen in two places:
- The hood over your cooking area
- The gas line running through the kitchen
These two connections work to suppress fire efficiently. The one in the hood cuts the fuel, while the other one applies the chemical fire suppressant.
The Basic Components of a Kitchen Fire Suppression System
There are many brands of kitchen fire suppression systems on the market. However, they all feature the same basic components that protect your kitchen from fires.
Here are the basic components of a kitchen fire suppression system:
1. Fire Alarm Panel
The fire alarm panel serves as the brain of the entire system. It monitors every device connected to the system and transfers information between each device.
2. Initiating Device
A fire suppression system in your kitchen either has a manual or automatic initiating device.
Manual devices need to be activated. Systems with manual initiating devices usually come with “pull in case of fire” signs.
On the other hand, automatic initiating devices activate on their own. They can detect physical changes that come with fire, such as heat and smoke.
3. Primary Power Supply
As the term implies, the primary power supply serves as the main source of power for your fire suppression system.
Its supply and backup include batteries, an emergency generator, or another emergency power device.
4. Secondary Power Supply
The secondary power supply will only work if something happens to the primary power supply. It ensures that your kitchen fire suppression system stays up and running even when the power goes out.
5. Notification Devices
As the name implies, these devices notify you when something happens. They usually include strobe lights, fire alarms, and audio devices.
How Does a Kitchen Fire Suppression System Work?
- The system shuts down the fire sources.
- All other sources of power will be cut off.
- The nozzles activate.
- The wet chemicals put out the fire.
- The kitchen hood gets rid of the smoke.
Kitchen fire suppression systems work like fire sprinkler systems. However, there are a few differences between the two.
Suppression systems use wet chemicals to put out fires. On the other hand, sprinkler systems use water.
Just like a sprinkler, a kitchen suppression system activates when they detect certain things. In this case, they do so after detecting flames or excessive heat.
When a fire occurs, the following happens:
1. The system shuts down the fire sources.
Once activated, the system shuts down the electrical source and gas valve. This eliminates the source of the fire.
2. All other sources of power will be cut off.
The system will also cut off the power to outlets and appliances under the hood to get rid of any shocks or sparks that can start another fire.
3. The nozzles activate.
Many kitchen fires, including those caused by burning oil, continue to spread even if the gas dies. For this reason, the fire suppression system has nozzles installed in the kitchen hood.
4. The wet chemicals put out the fire.
The system then expels wet chemical fire suppressant via its nozzles. The suppressant is developed to stop grease fires by covering the flame and depleting oxygen. It also prevents them from reigniting.
5. The kitchen hood gets rid of the smoke.
Lastly, the kitchen hood helps remove smoke from your kitchen.
A kitchen fire suppression system should work quickly, so the fire doesn’t spread. Remember, an efficient system can protect your family and staff.
For added safety, most kitchen hood suppression systems also come with levers. You can pull this down to activate the system if it doesn’t sense the fire early enough.
