The new generation of eco-friendly foam fire extinguishers eliminates traditional fluorine and phosphorus ingredients, being compounded from biodegradable natural materials. The foam left after extinguishing can degrade naturally, causing no pollution to soil or water sources. It is particularly suitable for areas with high environmental and cleanliness requirements, such as drinking water sources, food processing plants, and precision instrument workshops. Additionally, the residual liquid of the foam fire extinguisher is non-corrosive, causing no damage to the metal surfaces of storage tanks, pipelines, and equipment. After extinguishing, a simple rinse is required to restore the site's cleanliness, significantly reducing post-disaster cleanup costs and equipment maintenance expenses.
