Here is a great video of some basement removal techniques. This is another video from Dale Pekel, who looks like he may have gotten a promotion? Dale? Anyway, these props are able to be used for multiple drills and Dale is very generous with how to build them.
These two techniques are great and you can see that one must be comfortable and well trained in the use of the SCBA. Confidence comes from continued use and training. You must master the basics and know your tools like the back of your hand. This allows you to perform the more advanced tasks without worrying about the simple things because they become second nature.
Train hard and stay safe. Thanks Dale for another great video.
