From time to time, there are jobs that need to be done where extra special care needs to be taken in order to accomplish the task effectively and, most important, safely. Construction jobs fall into this category all the time. Everything from the traffic problems you drive extremely slowly through during rush hour on your way to and from work to the laying of pipes and cables beneath the ground.
Getting the actual goal of the job accomplished is often not as easy as it seems. Sometimes there are other jobs that have to be done to make things ready for the main job at hand. In the case of laying cable or pipes, one of the things that has to be done first is to dig a trench. Then, with the use of trench shoring equipment, trench shoring methods will be used to stabilize the excavation so that workers can safely do their jobs.
When it comes to excavation projects, regulations must be followed to ensure the safety of the worker involved. Every excavation project is going to be different. The types of shoring that will be used will differ and the excavation shoring design will be unique. While there is a great deal involved when it comes to using trench shoring equipment to stabilize your excavation, here are three things you should know an excavation site.
1.) The basic definition of what an excavation and a trench are actually has become standard.
OSHA has defined an excavation as any type of man-made cut, cavity, or depression that has been made in the earth by means of earth removal. The trench is an excavation that has come to be deeper than it is wide. Also, to be considered a trench, it must not be any wider than fifteen feet.
2.)The deeper your trench goes, the greater the protective system you need to put in place.
Protective systems need to be in place for every trench that is dug deeper than five feet. This can be amended if the excavation is made entirely in rock that is stable. If you get to twenty feet or deeper, the trench must be designed or signed off on by a professional engineer that is registered. Making sure the design is stable enough for workers to properly do their job gets more difficult the deeper you get. That is why an engineer has to be involved.
3.) Egress and access to every excavation trench must be carefully considered and available.
In trench excavations of four feet deep or deeper, OSHA requires that safe access and egress to all excavations for any worker should not be further than 25 feet away. Access and egress availability must include methods such as ladders, steps, ramps, or any other safe means of exit for all of the employees who are working in the trench or around it.
By using trench shoring equipment, workers can shore up the trench you will be needing to complete the project you need to have completed safely and confidently.
