4. Features of extinguishing fires and fires.
4.1. Powder fire extinguisher
4.1.1. The powder ejection time is 6 to 15 seconds.
4.1.2. When extinguishing fires with powder fire extinguishers, the fire is extinguished as soon as the combustion zone is surrounded by a cloud of powder of the required concentration, in addition, the cloud of powder has a shielding property, which makes it possible to approach a burning object at a close distance.
4.1.3. At the very beginning of extinguishing, one should not come too close to the hearth of the fire, since due to the high speed of the powder jet, a strong suction (ejection) of air occurs, which only blows the flame over the hearth. In addition, when extinguishing from a short distance, scattering or splashing of burning materials with a powerful jet of powder may occur, which will not lead to extinguishing, but will increase the area of the fire.
4.1.4. Powder fire extinguishers are not allowed to extinguish electrical equipment that is energized above 1000 V.
4.1.5. Dry powder extinguishers should not be used to protect equipment that could be damaged by powder ingress (some electronic equipment, collector-type electrical machines, etc.).
