Rescue training, across the board, is required. It has been mandated for quite some time now, but best of all perhaps is that confined space rescue training is voluntary. When attending to a person in distress, or a situation within confined spaces, there is every reason to believe that the rescue effort will be successful owing to the voluntary and spontaneous nature of the actions. On the contrary, the reluctance expressed during the rescue act brings about hesitancy and uncertain decisions and could lead to fatal mistakes being made.
If the rescue action is all voluntary, then at least you know that the person or persons in distress have a better chance of surviving their ordeals. Take the application of mouth to mouth in a confined space for instance. Not everyone will be ready to admit that they would be keen to do this. And take having to climb a ledge to rescue someone who is dangerously close to toppling over and injuring himself. Or worse. The person who volunteers is a brave soul indeed. You could agree that voluntary actions make all the difference in crisis situations.
You will find that on most occasions these volunteers already know what needs to be done. They do not panic and simply get on with the job of carrying out the rescue operation. They have confidence in the deeds they must carry out. Part of that stems from knowing what to do. And the knowledge, of course, is derived from the training that these good men and women put their hands up first to do.
Across all walks of life, confined space rescue training should be necessary. But in many instances, it has become mandatory. Assess your situation and use your common sense to know how this applies to you.
