The LiteGrip line of fire extinguishers can be sprayed directly into your motor. The clean air fire fighting foam causes no damage. When the fire is over, the foam evaporates making it environmentally safe. Additional advantages are smoke reduction by 75% or more. Unburned airborne black hydrocarbons are turned white, increasing visibility up to 75%. The natural consequences of these advantages are combustible vapor reduction which reduces dangerous reignition and smoke inhalation. Our fire extinguishers are rated for all class A and B fires.
