Commercial Kitchen Fire Suppression Systems
Providing fast, automatic fire control where open flames, hot oils, and extraction systems create elevated fire risk, commercial kitchen fire suppression systems protect staff, reduce downtime, and keep your kitchen compliant and operational.
Why kitchen fire suppression is essential in commercial environments
Commercial kitchens are one of the highest-risk environments for fire. With continuous cooking activity, high temperatures, and combustible grease deposits, a small incident can spread quickly, especially when flames reach extraction canopies or ductwork. Traditional extinguishers remain important, but they’re not always enough to control a fast-developing kitchen fire at source.
Effective kitchen fire suppression helps businesses protect people, prevent significant property damage, and minimise operational disruption. It can support insurance and compliance requirements by proving that specialist controls are in place for higher-risk cooking environments. Under the Regulatory Reform (Fire Safety) Order 2005, duty holders must take appropriate fire precautions based on the risks present, and many insurers expect suppression to be installed and maintained where commercial cooking operations create an increased likelihood of fire.
How do commercial kitchen fire suppression systems work?
Commercial kitchen fire suppression systems are designed to detect and suppress fires rapidly – often before they spread beyond cooking appliances or extraction systems. These systems typically include:
- Heat detection components
- A control mechanism
- Distribution pipework
- Strategically placed nozzles
When a fire is detected, the system activates automatically, releasing the extinguishing agent from dedicated cylinders through the nozzle network. A manual pull station is also included, allowing staff to activate the system if required.
This targeted discharge helps deliver rapid knockdown, cool the affected area, and reduce the chance of re-ignition, which is especially important in cooking oil fires and extraction hood incidents where heat can remain intense even after flames are controlled.
Types of kitchen fire suppression systems we install
Every commercial kitchen has a different risk profile, depending on cooking equipment, layout, ventilation design, and usage levels. At Facilities Fire, we recommend systems based on a full assessment of your appliances, extract canopy arrangements, and potential ignition risks, ensuring protection is suitable, compliant, and correctly positioned.
Our kitchen fire suppression solutions can be designed to protect:
- Cooking appliances – target suppression for high-risk equipment such as fryers, ranges, grills, and cooking lines
- Extraction canopies – rapid-response protection where heat and grease build-up can increase ignition risk
- Ductwork and ventilation routes – reducing the risk of fire spread through concealed extraction paths
In most environments, wet chemical suppression systems are used as the recognised standard for Class F fire risks, including deep fat fryers and cooking oils. This ensures suppression is delivered exactly where it’s needed, helping to control fires quickly, reduce re-ignition risk, and prevent escalation into wider building systems.
ANSUL kitchen fire suppression systems
At Facilities Fire, we provide the design, installation, and ongoing maintenance of ANSUL kitchen fire suppression systems, supporting commercial sites that require proven, widely specified suppression equipment. An ANSUL fire suppression system is commonly used in kitchen environments due to their automatic activation, controlled discharge, and suitability for high-risk cooking applications.
As with all fire suppression for commercial kitchens, correct specification and installation are essential. Our engineers ensure ANSUL fire suppression systems are installed to manufacturer requirements, aligned with your site fire strategy, and supported with the documentation and ongoing service checks needed for compliance and long-term performance.
