Gas suppression systems offer many benefits; they can be automatically activated, suppress fires which are too dangerous for manual human suppression and control fires which pose a risk of explosion if introduced to an oxygen rich atmosphere. Gas suppression systems work to remove oxygen in the atmosphere, reducing its combustibility. Gas suppression systems are particularly useful in computer rooms and archives, where water suppression would cause too much destruction. Benefits include:
Instant release; Fire suppression systems typically include seven components such as alarm, nozzle, fire detector and extinguishing agents. Each component works in chain formation to react to, contain and extinguish the fire. Gas suppression systems in isolated areas such as computer server rooms can tackle a fire before the building is even aware it has broken out.
Environmentally friendly; naturally occurring inert gasses and synthetic gasses work to remove the oxygen in the atmosphere. While some can cause asphyxia in humans, they do not deplete the ozone layer in the same damaging way other fire fighting chemical compounds can.
Minimal clean up; suppression by carbon dioxide is a swift and effective method which works without causing any damage to the equipment it protects. Commonly used in data centres, libraries and archives, it kills the fire without destroying the systems at risk. CO2 systems do not leave water or residue, minimising the damage to equipment.
Hypoxic air systems are revolutionary in that they maintain the oxygen content in the atmosphere at a level which is too low for fires but still high enough to humans. This concentration is typically between 14.5 and 15.5%. For the system to work no other source of fresh air can be present and ventilation must be ‘re-circulatory’.
