A dry chemical fire extinguisher is a fire extinguisher that disburses a dry chemical agent to actively suppress a fire. The agent will smother the fire (cut off oxygen) and halt the chemistry (free radical production) of a small blaze. Compressed nitrogen is the most common propellant for the powder. The powder used in the device can be any one of several different chemicals, and the ones we commonly see include ammonium phosphate, sodium bicarbonate, and potassium bicarbonate, or a combination of them and another ingredient. The type of chemical will determine its rating (class A, B and/or C fires), and the chemical properties of the agent will determine its effectiveness on a given fire type and what can be expected in cleaning up after the fire.
