Safety Precautions During A Demolition
Contrary to popular belief, demolition is not just about tearing down buildings or blowing off some structure. It is an engineered process aimed in the safe and efficient removal of various structures. There are different kinds of demolition processes. Each process requires precision and skill, which is why there are contractors that specializes in these construction phase.
The most common classification of demolition includes residential, commercial, and industrial demolition. Residential demolition applies to small houses and buildings which are no more than three stories. With demolition equipments such as elevated work platforms, cranes, bulldozers, and excavators, residential demolition can be done in just a matter of hours. Commercial demolition, as well as industrial demolition, requires heavier and larger equipment. The most popular among these equipments are the wrecking ball, though safety explosives are also commonly used.
But whether it is residential, commercial, or industrial jobs, the general process and the safety precautions that are required, stay the same. The general steps include land clearing and debris removal, excavation or grading, then the actual demolition.
While this may sound easy on paper, such a job needs several weeks of planning for a proper execution. Demolition contractors need to consider the design of the structure to be taken down. For instance, they conduct the removal of copper wiring, glasses, and other materials that prove to be hazardous on the demolition day itself as these can cause fire or abrasions. Contractors also need to consider the location of the project. If the structure is situated in a highly populated area, then building implosions should take place over explosions. Most of the time, a wrecking ball is made the best option.
Aside from these safety considerations, the Department of Labor of the United States of America requires its states to implement engineering surveys, utility location, medical services and first aid, police and fire contact, as well as fire prevention and protection before the start of any demolition.
An engineering survey involves determining the over-all condition of the building its framing, doors, floors, walls, etc. so that demolition contractors can plan the method and equipment to be used, as well as preparations for potential hazards such as fires, cave-ins, and injuries. Utility location is concerned with utility services such as water lines, electric lines, etc. that will be affected by the process. Contractors should have plans regarding the temporary relocation of these utilities. As its name suggests, medical services and first aid is about the emergency plans in case serious injury arises.
Finally, fire prevention and protection talks about plans in the event of explosions or fire. The plan involves assigning key personnel such as a police and fire contact, and an evacuation plan for all the workers.
The Department of Labor also demands that demolition teams to provide enough safeguards to the health and safety of their own workers. As stated earlier, there is a primacy placed on planning. Over-all planning, according to the standards of the Department of Labor, involves the specific methods to be used to bring the structure down, equipment necessary to do the job, and the actions and measures to be observed and done to perform the work safely.
