Specification standards for kitchen high-temperature fire nozzles — Fire protection solutions for large central Kitchens

The kitchen is the heart of every home and also one of the most fire-prone areas. According to statistics, most home fires are caused by cooking accidents. For this reason, it is vital to install high-temperature fire nozzles in the kitchen, as they allow for a quick response to control the fire effectively to protect people and property.
This article will take an in-depth view of the specification of high-temperature fire nozzles in kitchens, including installation locations, types, and maintenance to ensure their effectiveness and reliability.

When installing and maintaining high temperature fire nozzles in kitchens, it is important to follow the relevant regulations and standards to ensure their legality and effectiveness.
Below are some of the key regulations and standards:
1. State and local regulations
Understand the regulatory requirements for high-temperature fire nozzles, including installation and maintenance regulations, according to your local regulations.

2. NFPA standards
The National Fire Protection Association (NFPA) has published a series of standards on automatic sprinkler systems, such as NFPA13 and NFPA25. These standards contain detailed provisions for high temperature fire nozzles, including design, installation and maintenance.

3. Recommendations of the manufacturer
Always follow the recommendations and guidelines of the high temperature fire nozzle manufacturer to ensure proper operation.

4. Requirements of the local fire department
Work with the local fire department to understand their requirements and recommendations to ensure your high-temperature fire nozzles meet local standards.


Fires occur in the kitchen frequently, the main causes include cooking equipment malfunctions such as stoves, microwaves, and ovens, inadvertently forgotten stoves and open flames, or improper cooking operations.
Once a fire breaks out, time becomes the most important factor, and a rapid response can prevent the fire from expanding with less injuries and property damage.
High temperature fire nozzles play a vital role in this situation. They are an automatic spray system that detects high temperatures, activates quickly, and sprays a mist of water to extinguish the fire. Unlike traditional manual fire extinguishers, high-temperature fire nozzles do not require human intervention, which means that timely action can be taken when a fire breaks out, even if no one is present.
Besides protecting lives, high-temperature fire nozzles can reduce property damage caused by fires. Not only can a fire destroy household property, but it can also have an impact on neighbors and cause long-term disputes. Therefore, high-temperature fire nozzles for kitchens are an important means of preventing and controlling fires and helping to maintain the community safety.
There are several different types to choose from when selecting a high temperature fire nozzle for your kitchen, each with its own characteristics and application scenarios.

Here are some common types:

1. Quick response nozzles
Used to respond quickly to high temperatures, spraying water as soon as the temperature exceeds a pre-set threshold. Especially suitable for use near high temperature equipment such as stoves and ovens.

2. Wet chemical spray nozzles
A chemical is released to stop the fire from spreading in case of a fire. Suitable for appliances such as cooktops, stoves and ovens.

3. Dry powder nozzles
Dry powder will be released for extinguishing oil fires. It is very effective in the kitchen for dealing with grease fires.

4. Water curtain nozzles
A water curtain will be released to isolate the fire from spreading, which is often used in kitchens with an open design.

Position of installation

Correct installation location is a key factor to ensure that high temperature fire nozzles are able to work.
Below are some suggestions for installation locations:
1. Entrance to the kitchen
Quickly control the fire and stop it from spreading to other areas.

2. Over the stove
Extinguish stove-caused fires quickly to reduce cooking hazards.

3. Below the hood
Since grease and oil can easily accumulate underneath the hood, installing a high temperature fire nozzle can effectively prevent grease and oil fires.

4. Near high-temperature equipment such as microwaves and ovens
These devices are prone to fires, installing high-temperature fire nozzles allows for a quick response to the source of the fire.

5. Sink
Respond to fires that may occur when the water is boiled.

6. Partition at the open kitchen
To control the spread of fire.

7. Kitchen ceiling
Ensure that the source of the fire does not spread to other areas through burning smoke.


After installing a high-temperature fire nozzle, it is critical to maintain and inspect it periodically to ensure that it is always in good working condition.
Below are some suggestions:
1. Periodic inspection
Inspect high-temperature fire nozzles at least every six months to make sure they are not damaged or clogged.

2. Cleaning
Clean the nozzle regularly to ensure it is not polluted with dust, grease or other impurities.

3. Test
Periodic testing in accordance with the recommendations of the manufacturer to ensure that high-temperature fire nozzles can respond quickly to high temperatures.

4. Replacement
If the nozzle is damaged or deteriorated, it should be replaced immediately. Damaged nozzles may not work properly in fire.

5. Keep it smooth
Make sure there are no obstacles around to block the spray from the nozzle, including pots, pans, plates or other items.

6. Training
Train family members on the proper use of high-temperature fire nozzles and how to act in case of a fire.


High temperature fire nozzles for kitchens are essential for protecting life and property, especially around hot cooking equipment. Proper selection, installation and maintenance allows fire nozzles respond quickly to fire sources, which can prevent the spread of fire and minimize damage.
Following regulations and standards, regular inspections and maintenance, and training for family members are all critical steps in ensuring that high-temperature fire nozzles can work effectively. By adopting these measures, we can reduce the risk of fire in our kitchens and keep our homes safe.
