Dry Chemical is a powder composed of very small particles usually of sodium bicarbonate, potassium bicarbonate, urea-based potassium bicarbonate, or monoammonium phosphate with added particulate material supplemented by special treatment to provide resistance to packing, resistance to moisture absorption (caking) and the proper flow capabilities[FIRE EXTINGUISHING MECHANISMS]Interruption of the chain reaction sequence.Heat absorption effectsMultipurpose Dry Chemical is usually monoammonium phosphate-based and is effective on fires in ordinary combustibles, such as wood or paper, as well as on fires in flammable liquids, etcA total flooding system means a supply of dry chemical permanently connected to fixed piping,wiht fixed nozzles arranged to discharge dry chemical into an enclosed space or enclosure about the hazard.This type of system shall be used only where there is a permanent enclosure about the hazard that is adequate to enable the required concentration to be built up.
