System Overview

Mounted extinguishing systems include things like water sprinkler systems, CO2 systems, foam systems and dry powder systems.

Environmental fears mean that the employment of Halons – an exceptionally efficient group of extinguishing chemicals – is actually prohibited from commonplace use, besides specific applications, for instance, on aircraft, the military and law enforcement. Nevertheless, there are a variety of inert gasses of halocarbon gasses currently available as a substitute.

The components that make up a fire suppression system generally comprise of discharge nozzles; piping; control panels; release or warning alarms; hazard alert or caution signs; automatic fire-detection devices; manual discharge stations; and storage containers and extinguishing agents.

Replacement of Halons
Environmental fears – such as the depletory impact Halons have on the ozone layer – have resulted in legal guidelines against the utilisation of Halons in fire-extinguishing systems. Although EC Regulation 2037/2000 made the usage of Halon 1301, Halon 1211 and Halon 2402 illegal for use in every fire-fighting equipment considered non-critical, the industry continues to look for a practical replacement. Between 2000 and 2004, all non-critical equipment which contains these three Halons has been decommissioned.

Common alternatives currently obtainable on the market consist of inert gasses, clean agents and water mist systems. Inert gas systems operate by discharging atmospheric gasses (argon, nitrogen and CO2) directly into an area, in so doing, lowering the quantity of oxygen and smothering the fire. Clean agents, mainly halocarbons, are stored as fluid at room temperatures but are transformed into a gaseous state by the delivery nozzles. They operate by chemically destroying the reproduction of flames. Water mist technology, which utilises an extremely fine water spray to extinguish flames, is among the most current advancements.

Each of these systems, nevertheless, has its own dangers and restrictions. For instance, inert gas systems could be hazardous if the correct balance of gasses isn’t achieved, while clean agents demand big storage locations for their liquid condition. Water mist systems should not be used in computer rooms, data centres and buildings having a similar use, as a result of water can wreak the electrical equipment.
