Fire Gone is a wonderful alternative to traditional fire extinguishers because the discharge time is much faster which helps reduce loss of life and property. It is a trigger style aerosol which, once activated, releases a powerful foam blanket on the ignited material to suppress the fire. Fire Gone utilizes a formula that has been researched and developed for over 20 years, resulting in a revolutionary way to extinguish small fires safely and rapidly. Fire Gone is specially formulated to form a vapor suppressing aqueous film on hydrocarbon type fuels or a polymeric membrane on polar solvent/water miscible type fuels. The molecules then form a vapor suppressing seal for rapid control of fire while blocking the release of further vapor fuel. Fire Gone Formulation encapsulates the fire itself while forming a high quality foam blanket that floats on the outside of the ignited material, starving it of oxygen. Water contained in this foam blanket cools the ignited material while continuously forming more foam barriers. Fire Gone has been tested by the internationally recognized Bureau Veritas Consumer Product Services Inc, to be effective on: Class A – wood straw, hay, cotton, tires, fabric, paper. Class B – gasoline/diesel, fuels. Class C – electrical equipment fires. Class K – grease, cooking oils, animal fats, vegetable fats.
