Rescue equipment and techniques
Portable steps usually have on the superior part of them a metal ferrule with a curve on the center where you can hook the snap link. There are certain stairs that although in appearance don't look very sturdy, are quite safe and support the load, the inside of these have a steel cable that runs all the way through it to avoid it from unhinging in case it breaks. The search zones that could arise due to a building collapsing could occur in closed or open spaces, on different levels, which include: underground, very high, moderate height, in which case one or several floors of the a building could have been affected, the whole building or several. It is very important that the people andworking in confined spaces while on a search are highly trained to be able to confront these types of situations. You will need to avoid for example, having one of the guides from going into shock from not being well prepared since this could have disastrous results.
All of the search and rescue guides need to learn before hand how to control themselves from panicking through rigorous training and be aware of what their personal limits are, whether in training or in a real situation. It has been observed that there is a chemical substance that the body lets off when doing physical force that can cause a person to become stressed, in such a way that the physical energy used during the search and rescue while in confined and closed spaces can sometimes be seen while in these dangerous situations. Obviously a person that is well prepared will have less risk of becoming affected by these types of problems because their body will be trained to take and tolerate these situations. It has also been observed that certain substances such as caffeine can increase the anxiety levels of a person and it is suggested that people control their amount of intake while on a search and rescue mission.
