Range hoods are often used in kitchens and other areas with potential fires. But do range hoods come equipped with fire suppression systems?
This article will teach you what a range hood fire suppression system is, how it works, and if range hoods have them installed by default.
No. Commercial range hoods often feature fire suppression systems (required by law). However, residential hoods do not. There are, however, many devices you can purchase that will easily integrate into your existing reassured to offer you the safety and convenience of a fire suppression system.
What is a range hood fire suppression system?
A fire suppression system is a precautionary measure to prevent fires. A range hood fire suppression system consists of a tank holding the extinguishing agent and sprinklers installed above the hood.

The most commonly used fire suppression system for range hoods is a wet chemical system. Water-based and pressurized gas systems are two more types of systems.
Fire suppression systems can also cut off the gas to all appliances, eliminating the need for you to rush to do so. It can also disconnect power to outlets beneath the hood, preventing a fire hazard if water or chemicals are discharged.

How do range hood fire suppression systems work
Yes. Consider sprinklers on school or office building ceilings. These are fire suppression methods that use water.
Range hood fire suppression systems work similarly, except that most employ chemicals rather than water (water on a grease fire can be very dangerous).
When excessive heat comes into contact with the sprinkler, it automatically activates. Most fire suppression systems activate at around 150 degrees Fahrenheit. They are not activated by smoke, like a smoke alarm.
In business settings, particularly restaurants, fire suppression systems for range hoods are required by law. If a fire starts, the range hood should be able to handle the job for you. There will be no need to extinguish the fire manually. Business owners also do not want any potential legal issues arising from employee injuries. So to protect everyone’s safety, fire suppression systems are essential.
What are the benefits of range hoods having fire suppression systems? (Advantages)
Upgrading to a high-quality fire suppression system can be an easy way to enhance your kitchen’s safety. Some of the benefits include:
- Preventing kitchen fires is far less expensive than fixing structural damage after a fire.
- A wet chemical kitchen hood fire suppression system may be installed in any size kitchen, and its quick fire-extinguishing capabilities provide absolute safety.
- The kitchen range hood fire suppression system detects and extinguishes fires quickly in their early stages.
- Many clean chemical fire suppression systems are environmentally friendly and do not deplete the ozone layer.
Do range hoods come with fire suppression systems?
Fire suppression systems are often installed In commercial buildings. But this is not the case with residential hoods. However, various devices available for purchase may be incorporated into your preexisting system to provide you with the protection and convenience that a fire suppression system provides.

What are the types of range hood fire suppression systems?
Fire suppression systems come in various types, each designed to meet specific needs. Some common types of range hood fire suppression systems include:
Wet chemical suppression system
The typical fire suppression system, such as that seen in a commercial kitchen, is the wet chemical suppression system. This approach prevents kitchen fires in both household and commercial settings. The suppressant is a liquid chemical that rapidly cools the flames when sprayed into the damaged region. Its efficacy stems in part from its quick responsiveness to fire.
When the liquid comes into touch with cooking oils and fats, it reacts to form foam, which cools the affected area and prevents the fire from rekindling.
Wet chemical suppression systems must meet the requirements of NFPA 17A (standard for wet chemical extinguishing systems) and NFPA 96 (Standard for Ventilation Control and Fire Protection for Commercial Cooking Operations).
Dry chemicals suppression system
Dry chemical suppression systems are typically used in industrial environments like paint spray booths and big off-road vehicles. Dry chemical systems use Class ABC or Class BC dry chemical compounds to suppress flames efficiently where and when water is unavailable.
Because dry chemical systems are rechargeable, electrical extinguishing systems readily deployed in commercial and industrial settings enable quick access and efficiency. In addition, because they are non-conductive, they may be used to put out flames in non-combustible materials and flammable liquid fires involving live electrical equipment.
Dry chemical systems must meet the requirements of NFPA 17 (Standard for Dry Chemical Extinguishing Systems) and NFPA 33 (Standard for Spray Application for Safe Use on Flammable and Combustible Materials).
Do you need a fire suppression system in your range hood?
A fire suppression system in the kitchen is not required for homeowners. However, If you run a restaurant, you will need a fire suppression system in your restaurant kitchen. In addition, fire suppression systems are required in other commercial cooking contexts, although restaurants are the most prevalent.

Is a fire extinguisher a fire suppression system?
A fire extinguisher is certainly a device that can suppress a fire. However, it is not a fire suppression system, nor a system built into the kitchen or the room.
What are the most frequently used fire suppression systems?
The most prevalent fire suppression system depends on water, and most people have these installed in companies and buildings.
