  2. Nitrogen generator - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_generator

    Membrane nitrogen generator providing supervisory gas to dry pipe fire sprinkler system. Fire Protection: The fire protection industry uses nitrogen gas for two different applications - fire suppression and corrosion prevention. Nitrogen generators are used in hypoxic air fire prevention systems to produce air with a low oxygen content which will

  3. Hypoxic air technology for fire prevention - Wikipedia

    en.wikipedia.org/wiki/Hypoxic_air_technology_for...

    Hypoxic air technology for fire prevention, also known as oxygen reduction system (ORS), is an active fire protection technique based on a permanent reduction of the oxygen concentration in the protected rooms. Unlike traditional fire suppression systems that usually extinguish fire after it is detected, hypoxic air is able to prevent fire.

  4. Gaseous fire suppression - Wikipedia

    en.wikipedia.org/wiki/Gaseous_fire_suppression

    Gaseous fire suppression, also called clean agent fire suppression, is the use of inert gases and chemical agents to extinguish a fire. These agents are governed by the National Fire Protection Association (NFPA) Standard for Clean Agent Fire Extinguishing Systems – NFPA 2001 in the US, with different standards and regulations elsewhere.

  5. Purging (gas) - Wikipedia

    en.wikipedia.org/wiki/Purging_(gas)

    In fire and explosion prevention engineering, purging refers to the introduction of an inert (i.e. non-combustible) purge gas into a closed system (e.g. a container or a process vessel) to prevent the formation of an ignitable atmosphere. Purging relies on the principle that a combustible (or flammable) gas is able to undergo combustion ...

    The GAG unit emits carbon dioxide, nitrogen and water vapour. [4] The gases lower the oxygen levels, suppressing fires, and forcing methane out of the mine. [5] A unit is capable of pumping a volume of 25 m 3 /s, creating levels of less than 1% oxygen. [3] When fully assembled, the unit is 12 metres long and weighs 2.5 tonnes. [4]

  7. Gas generator - Wikipedia

    en.wikipedia.org/wiki/Gas_generator

    A small pyrotechnic charge triggers its decomposition, producing nitrogen gas, which inflates the airbag in around 30 milliseconds. A typical airbag in the US might contain 130 grams of sodium azide. [11] Similar gas generators are used for fire suppression. [12] Sodium azide decomposes exothermically to sodium and nitrogen.
