How does fire retardant work?
Fire retardant contains salts (typically fertilizers) that alter the way wildfires burn, decreasing fire intensity and slowing the advance of the fire, even after the water in the fire retardant has evaporated. The water in long-term fire retardants serves primarily to aid in uniform dispersal of the chemical over the target area.
