ENTRY INTO ENCLOSED SPACES — PART 6 — CORRECT USE OF BREATHING APPARATUS (VIDEO)
|D O W N L O A D|
The last part of the training series, and this one is devoted to the correct use of the BA, standing for the breathing apparatus, in the course of the emergency and rescue operations. In our job, we get plenty of fresh air and the air contains oxygen meaning to stay alive, but just how much air do we need? It depends on the body's energy requirements. During rest, we may only use sixteen to twenty liters a minute.
But, if you are wearing breathing apparatus, in an emergency this can rise to forty liters of fresh air peach minute due to the raised stress level of the wearer. If extra-heavy work is performed at the same time, fifty to sixty liters of air may be consumed. But why? When physical effort is required, the body needs more oxygen. Fresh air contains twenty-one per cent oxygen; this will never change.
So, the only way of getting more oxygen is to increase breathing rate... Check the accompanying training booklet on the correct use of BA and, of course, feel free to download and go through the content of all previously released training videos belonging to the Entry Into Enclosed Spaces series and covering the Awareness, Preparation and Procedures, Equipment, Enclosed Space Entry itself and Emergency Procedures and Rescue.
