Fire suppression systems are particularly applied to high value risks where a minor fire within a critical area could have devastating financial repercussions or a critical effect on the ability to deliver services for themselves or their clients. These specialist types of suppression systems ensure that high value assets are protected from fire and the effects of general fire fighting.
There are three main types of fire suppression systems:
- Inert Gaseous Suppression Systems
- Chemical Agent Extinguishing Systems
- Watermist Suppression Systems
Inert suppression systems extinguish fires based on the principal of oxygen depletion where the oxygen concentration is reduced below 15% which is an acceptable level for human exposure but insufficient to allow fire development. Chemical Agent Systems generally act on fires by physical means by lowering the temperature of the flame and fuel to a point at which the combustion process cannot be sustained. When systems operate effectively they ensure that operations resume as quickly as possible and that both physical damage and financial losses are minimised.
Fire Suppression Systems can be activated manually or automatically. The extinguishant is discharged through a pipe network system within the protected area and disperses equally through discharge nozzles.
In normal practices the fire detection system will identify the presence of a fire. A signal is sent to the dedicated control panel, sound the appropriate alarms, shut down any essential dedicated services, then release the fire suppression system into the enclosure.
All designs and installations are undertaken in accordance with the approved standard BS EN 15004 Part 1, BS 6266 & BS 7273.
