| 摘要 | The present invention provides a method for extinguishing fire, comprising: (A) preparing a CFC-free and phosphorus-free aqueous fire extinguishing agent using a composition comprising 1-70 wt % of a sulfosuccinic acid ester; 1-30 wt % of a wetting agent; and rest in water; (B) diluting the CFC-free and phosphorus-free aqueous fire extinguishing agent by water to form an aqueous solution; and (C) spraying the aqueous solution to a space containing a burning substance. The present invention not only enhances the wettability and permeability of water, but also increases its affinity to burning substances; accelerates cooling of burning substances; inhibits further combustion; reduces water for firefighting; reduces smoke and emission; mitigates environmental problems caused by haze substances from combustions on the ground and in the air and all possible related health hazards. The CFC-free and phosphorus-free aqueous fire extinguishing agent is biodegradable, non-toxic to human and environment, and easy to use. | ||||||
