And the isolated breathing protective equipment such as a compressed air respirator, a compressed oxygen respirator, a chemical oxygen respirator and the like used in the traditional urban fire fighting are not suitable for forest and grassland fire fighting with open working space, huge working area and extremely long working time. The breathing protection equipment that china forest fire fighter equipped with at present is the forest fire prevention gauze mask except that the towel, and this equipment is similar to traditional personal protection gauze mask, only can filter particulate matters such as smoke and dust in the scene of a fire ambient air, can not block the transmission of heat to respiratory, can not provide reliable breathing protection for the personnel under emergency.
The existing forest fire-proof mask consists of an outer layer, a smoke filtering layer and a skin-friendly layer. The outer layer is high-grade fiber cloth with high temperature resistance and flame retardant function, and can block the invasion of large-particle smoke dust. The smoke filtering layer is made of non-woven fabrics with electrostatic adsorption function, can adsorb smoke particles with smaller particle size (less than 5 μm), and has the function of filtering smoke. The skin-friendly layer of the innermost layer is made of absorbent pure cotton fabric and has good moisture absorption. Although this forest fire prevention gauze mask is optimized than traditional gauze mask, still can only play the effect of particulate matter such as filter smoke and dust of certain degree, when needing to pass through the live wire for a short time or meet the condition that the flare opening invades suddenly among the fire extinguishing operation in-process, can't provide high temperature air cooling's function, fire fighter's effective respiratory protection and life safety still can't be ensured.
