正如大家所知,目前研制与使用的一氧化碳自救器及自给式氧气呼吸器在井下发生灾害时,能够使井下人员安全地避难和撤离。目前,正从各种角度研究自给式氧气呼吸器。实际上,一氧化碳防毒面具比氧气呼吸器具有优越性,便于携带,处理与使用方法都简便。另一方面,氧气呼吸器要求配备高水平的自给氧气的呼吸保护装置。满足使用时间要求的原有自给式氧气呼吸器携带时显得过大。
As we all know, presently developed and used carbon monoxide self-rescuer and self-contained oxygen respirators in underground disasters, to enable miners to safely refuge and evacuation. At present, self-contained oxygen respirators are being studied from various angles. In fact, carbon monoxide gas masks superior to oxygen breathing apparatus, easy to carry, handling and use methods are simple. Oxygen breathing apparatus, on the other hand, requires a high level of self-contained breathing apparatus. The original self-contained oxygen respirator that meets the time requirements of use appears too large to carry.
