Description

Technical Field

[0001] The utility model relates to the technical field of chemical fire fighting, in particular to a fire fighting device for chemical safety. Background Art

[0002] Most materials in chemical companies are flammable, explosive and toxic substances. After a fire or leakage accident, it is very easy to explode, re-ignite and explode. The spread range is large and the speed is fast, resulting in three-dimensional, large-area, and multiple fire points.
