Fire Suppression systems
What is Fire Suppression?
Fire suppression aims to limit the extent of a fire in special risk areas detecting, suppressing and extinguishing the fire during the critical early moments.
When is Fire Suppression needed?
Fire suppression systems are needed in all areas where a fire can get out of control rapidly, especially in industries that work with highly combustible materials or use high fire-risk processes.
Gas suppression systems are used in occupied and unoccupied areas which contain high value assets where valuable items must not be damaged by a fire extinguishing agent. For example, telecommunication areas, server rooms, control centres, document storage areas, museums and libraries. Gas suppression can work in two ways:Oxygen reduction
This is also known as an inert gas system. In an oxygen reduction system the level of oxygen in the room or enclosure is reduced significantly, to a level that means most combustible materials will be unable to burn and the fire is extinguished.Chemical suppression
In a chemical suppression system a blend of manufactured gases are used to absorb the heat of the fire, meaning the temperature of the fire falls below the level it can propagate and the fire is extinguished.
You can find out more about the two types on our gas suppression page.
Sprinkler systems - Water Deluge
Sprinkler systems are usually designed to protect the whole building, delivering water not only to the location of the fire but also pre wetting the surrounding areas to avoid the fire spreading further. Deluge systems are used in rooms with high ceilings to quickly wet down an entire hazardous area in facilities that contain high flammable liquids and chemicals.
Water Mist - Minifog
Water mist and minifog are fixed systems designed to protect industries using continuous presses and multi opening presses as in the production of MDF and HDF boards. Combustible materials such as wood chips, fibres, adhesives, hydraulic and thermal hydraulic oils can ignite by overheating or friction. In the event of a fire, water droplets discharged as mist remove the heat and displace oxygen to an extent where combustion can no longer be maintained. We have more information on the Minifog system on our Minifog page.
When flammable liquids or plastics catch fire, the fire spreads very quickly and toxic combustion gases are emitted. Foam is used as a blanketing and cooling agent, coating the fuel to prevent contact with oxygen resulting in suppression. Foam extinguishes flammable or combustible liquid fires in four ways.
1. Excludes air from the flammable vapors.
2. Eliminates vapor release from fuel surface.
3. Separates the flames from the fuel surface.
4. Cools the fuel surface and surrounding metal surfaces
