Fire suppression systems
Fire suppression systems are used to extinguish a fire or prevent it from spreading in a building and choosing the correct system will depend on several factors such as:
- The type of equipment being protected.
- The building infrastructure, ensuring that it suitable for the intended fire suppressant.
- The fire detection system - automatic heat sensors, smoke detection using air sampling technology, manual activation etc.
- Environmental considerations - prevention of discharges.
- Storage facilities for the fire suppressant.
These are basically five systems, which rely on dry chemicals and/or wet agents:
- Gaseous or liquid suppressant stored under pressure – best suited for protecting rooms containing electrical equipment – servers, switch gear etc.
- Foam suppression - mainly used for commercial kitchens, where nozzles located under cooker canopies discharge the agent.
- Water mist system - commonly replacing sprinklers in data rooms, where the mist evaporates and depletes oxygen, rather than cooling.
- Foam deluge system - mainly suitable for applications where water or gas cannot be used, e.g. oil storage tanks. A simple sprinkler disperses an expanding suppressant comprising foam concentrate mixed with water.
- Pneumatic heat detection tube. Essentially an extinguisher with a valve and a heat detection tube, which acts as the detection and propellant feed for the agent. When the temperature reaches a certain level, the pipe ruptures and the suppressant is discharged directly onto the heat source. This system is ideal for electrical switch cabinets, vehicles and small machinery.
