Demolition workers are in charge of overseeing the safe destruction of buildings. They take a look at the construction of the building and then use machinery and explosives to destroy it. Safety is a priority in this trade, particularly with the heavy machinery and blasting used to tear down buildings. When working a demolition job, you first gut the interior of the building, salvaging as much material as you can, before beginning work on the outer walls and main structure. Depending on the type of building, more care may be necessary to salvage as much as possible.
