How often should a competent person check the safety of an excavated trench according to OSHA?

A competent person should check the safety of an excavated trench at least once a day, as well as after any significant weather events such as rainstorms. This is crucial because water accumulation can affect the stability of the trench walls, increase the risk of cave-ins, and compromise safety. Daily inspections ensure that any changes in soil conditions or other hazards are detected early, allowing for necessary precautions or corrective actions to be taken immediately.

The requirement for these regular checks originates from OSHA regulations, emphasizing the importance of active and ongoing monitoring to protect workers engaged in trenching operations. By adhering to this standard, employers demonstrate their commitment to maintaining a safe work environment, which is vital in mitigating the inherent risks associated with excavation work.
