The ProfitDig guys talk about trench boxes, chains and slings - essential safety equipment used on a jobsite to prevent injury from collapsing trenches. Chains and sligns are used to lift heavy items. Most trench boxes weigh 8 - 12 thousand pounds, so they are very heavy devices. They must be used correctly based on soil and OSHA requirements, which vary from state to state. Trench boxes must be tagged properly. A missing tag will rquire recertification. It is critical that these items be set up correctly. Items used for lifting must also be tagged and dated.
