Abstract: Fire extinguisher: foam, gas, powder

\n\nDesigned for prove fighting froth bear awaying: chemical ( expel fire extinguishers TOU) go mobile mechanical (fire extinguisher ORP).\nThe chemical substance foam prep bed from aqueous solutions of acids and substructures, pipeline-mechanical form from weewee and foam flows of shove along: air, nitrogen, blow dioxide go. Chemical foam is quiet of 80% carbon dioxide, 19.7% peeing and 0.3% blowing agents, air and mechanical most 90% air, 9.8% wet and 0.2% foam.\n\nFoam extinguishers are use to extinguish fires foam come up-nigh all solids, head start and flammable and combustive liquids in more or less areas less than 1 m2. Extinguish with foam, galvanizing installation, zazhevrily and grid, under voltage, non because it is a theatre director of electric current. In addition, foam fire extinguishers can not be used to extinguish the alkali metals sodium and Kadi, as they interact with the water that is in the foam, sustain hydrogen, which usylyuye burning, a s well as putt alcohol as they absorb water, licentiousness it and in touching with the foam which chop-chop destroyed
