Dry chemical fire suppression systems extinguish fire by discharging a dry chemical powder into the space. The powder is stored in a pressurized tank. When activated, a high-pressure nitrogen cartridge opens the valve, releases the powder into the piping and discharges it through the nozzle. There are several common compounds used in these systems: sodium bicarbonate, for Class B and some class C fires and mono-ammonium phosphate, for ABC fires. After discharge, it is necessary to recharge the system, and there is significant cleanup required in the space.
