Fire Suppression Systems

Keeping kitchens safe with fire suppression systems

Modern kitchens are often a prime threat in terms of fires because they have constant high temperatures and flammable liquids. In these instances, a fire suppression system is needed to ensure that if a fire does break out, it can be dealt with quickly and efficiently, keeping damage and disruption to a minimum.

Our fire suppression systems are designed to safeguard against the eventuality. They work mainly via water mist, which is released from nozzles above the kitchen appliances to tackle fires, not only by cooling but also by reducing the oxygen taken up of the fire, thus also preventing further damage to your vital equipment.

Fire Suppression Systems are being specified more by insurance companies as they recognise that a kitchen in a building is one of the major risks of a fire/disaster and a potential large claim.

Flammable liquids, gases, food, oil and ignition sources are a major concern for insurance companies, and owners of hotels and restaurants are now recognising this risk. In larger buildings we recommend interfacing your fire suppression system with duct work dampers to stop the fire spreading through the building.

Nozzles placed under the cooker canopies and over each risk propel a water-based agent with a chemical foam type mix over the risk. This is usually triggered by a heat link (a thermal link fixed to a wire which breaks and then releases the valve) or a manual pull switch.

The agent is usually situated near the risk in a box. This is basically a large fire extinguisher. Pipework from the nozzles terminate at this point and a valve operates the release. Once the system is triggered the agent is propelled from this valve/cylinder to the nozzles.The agent is a water-based chemical which acts like a foam extinguisher. This is to ensure any flammable liquids are covered by the foam to avoid a boil over from any oven/fryer that may be still switched on, and stops the oil from re-igniting.

Watermist systems can be used for kitchens and can be a more cost-effective solution to Ansul systems and other water chemical systems. However, careful design is needed and approval from insurers.

Other elements of the fire suppression system are triggered from automatic fire detection and back to a fire extinguisher panel. The detection and most equipment in this area needs to be stainless steel to avoid corrosion and the damage/effects of heat.
