Dry powder fire extinguisher

Powder fire extinguishers are special devices containing fire extinguishing powder and designed to extinguish fires at the initial stage of their occurrence of class A - combustion of solid combustible substances, B1 - combustion of liquid substances insoluble in water, C - combustion of gaseous substances, and an additional class E - electrical installations under voltage up to 1000 V. Powder fire extinguishers have a significant advantage in extinguishing classes of fires than carbon dioxide, but they have their drawbacks: the first is that the fire extinguishing powder is not able to cool the combustion product, which means that re-ignition may occur, the second is a fire extinguishing charge, which contained in the body of the fire extinguisher has the ability to cake. Therefore, we advise you to shake the fire extinguisher at least once a month, turning it upside down several times to keep the fire extinguisher in working condition, as well as annually recharge powder fire extinguishers and carry out maintenance of fire extinguishers.
