为了全面推广应用AYH型压风呼吸器，我们对其防尘、毒等效果进行了卫生学评价。结果是：①工作中感到呼吸通畅、空气清新、凉爽和舒适；结束时鼻腔未见粉尘痕迹，无咳嗽及吐黑痰现象。②阻尘率和防硫酸雾效率均达100％，防CO效率达97.62％，防SO2效率达99．63％，同时还具有良好的防暑降温效果。故认为该呼吸器的防尘、毒效果及防暑性能均良好，适合在接尘、毒等工种岗位上推广应用。
In order to fully promote the use of AYH type pressure ventilation respirator, we conducted a hygiene evaluation of its dustproof, toxic and other effects. The results are: ① breathing during work feel fresh, fresh air, cool and comfortable; end of the nose no trace of dust, no cough and spit black sputum phenomenon. ② The dust-blocking rate and the anti-sulfuric acid mist efficiency are up to 100%, the anti-CO efficiency is up to 97.62% and the anti-SO2 efficiency is up to 99.63%, meanwhile, it also has a good effect of preventing sunstroke and cooling. Therefore, the respirator’s dust-proof, toxic effect and heatstroke prevention performance are all good, and are suitable for popularization and application on jobs of dust collection, poisoning and the like.
