  2. Active fire protection - Wikipedia

    en.wikipedia.org/wiki/Active_fire_protection

    Fire can be prevented by hypoxic air. Hypoxic air fire prevention systems, also known as oxygen reduction systems are new automatic fire prevention systems that permanently reduce the oxygen concentration inside the protected volumes so that ignition or fire spreading cannot occur. Unlike traditional fire suppression systems that usually ...

    en.wikipedia.org/wiki/Fire_protection

    Fire protection is the study and practice of mitigating the unwanted effects of potentially destructive fires. [1] [2] It involves the study of the behaviour, compartmentalisation, suppression and investigation of fire and its related emergencies, as well as the research and development, production, testing and application of mitigating systems.

    en.wikipedia.org/wiki/Compressed_air_foam_system

    Air pressurized water (APW) fire extinguishers are commonly converted into makeshift CAFS extinguishers by drilling two 1/8-1/16 inch holes in the pickup tube above the water line. The unit is then filled with 1.5 US gallons (5.7 L) of water and class A foam, AFFF , FFFP or commercial detergent is added to the water in a 1% ratio for class A ...

    en.wikipedia.org/wiki/Air_pressurized_water

    A standard APW extinguisher in the United States contains 9.5 litres (2.5 US gal) of water in a stainless steel tank. The water is discharged by means of a 13 mm (1 ⁄ 2 in) hose, with a smooth-bore nozzle attached to the tip. They will initially produce a 12–15 m (40–50 ft) stream of water, with a discharge time of about 50 seconds.

    An Ansul fire suppression system in a hospital cafeteria Fire suppression systems are used to extinguish, control, or in some cases, entirely prevent fires from spreading or occurring. Fire suppression systems have an incredibly large variety of applications, and as such, there are many different types of suppression systems for different ...

  8. 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.

  9. Fire sprinkler system - Wikipedia

    en.wikipedia.org/wiki/Fire_sprinkler_system

    A fire sprinkler system is an active fire protection method, consisting of a water supply system providing adequate pressure and flowrate to a water distribution piping system, to which fire sprinklers are connected. Although initially used only in factories and large commercial buildings, systems for homes and small buildings are now available ...
