Recently, we found a routine inspection, a substation is a positive pressure air respirator aging pipeline caused by compressed air leak. We draw a lesson from the global positive pressure air respirator inspection, results also found one case sealed well positive pressure air respirator. Positive pressure breathing apparatus, fortunately, did not use these two positive pressure breathing apparatus pressure relief Otherwise, fire fighting and rescue field personnel wear a positive pressure air breathing apparatus pressure relief, not only to deal with the accident will delay also trigger fire fighting by poisoning. Positive-pressure air the respirator pressure relief phenomenon reason three: First, the individual product quality problems; inappropriate exaggeration product quality publicity mistaken for "foolproof"; usual "care" plus, fearing that "moving bad "it, but did not dare check and trial, positive pressure oxygen breathing apparatus entered the maintenance and management of misunderstanding; scene a small number of staff working is not responsible for the routine inspection sloppy, a mere formality. The above phenomenon does not pay attention to the passage of time, it will make a positive pressure air respirator as decoration of the substation, which is very dangerous. Therefore, the author recommends that the relevant units should strengthen the management of positive pressure breathing apparatus, eliminate fake and shoddy products, required to do a routine check on a regular basis, the timely replacement of aging, damaged seals and piping, so that the relevant personnel are familiar with the principles and use. Dadong District, South Carolina avenues 4-2 the No. Shichiku Ming County district in the morning of August 10, a man entered the thermal wells ready to turn off the heating valve accidentally collapsed in wells due to gas poisoning. 20 minutes later, after the dangerous ground they found, is a man adventure into the well to rescue respirator, the results also collapsed in the well.
