When workers are required to enter a trench, shoring is required if the trench reaches what minimum depth?

Shoring is a crucial safety measure in trench work, especially to prevent collapses that can endanger workers. According to OSHA (Occupational Safety and Health Administration) regulations, if a trench is 5 feet deep or deeper and workers are required to enter it, shoring, trench boxes, or other protective systems must be implemented to ensure their safety. This requirement is rooted in the understanding that the risk of trench collapses significantly increases at this depth, making it essential to have proper safety measures in place. Therefore, the requirement for shoring to be mandated specifically at the minimum depth of 5 feet ensures adherence to safety standards and helps protect workers from potential hazards.
