According to OSHA, ladders or steps are required in all trenches or ditches at what depth for an adequate means of exit?

The requirement set by OSHA for ladders or steps in trenches or ditches is designed to ensure the safety of workers who may need to exit a trench quickly in the event of an emergency. For trenches that are 4 feet deep or more, ladders, steps, or other adequate means of exit must be provided within the trench. This regulation aims to prevent accidents such as falls or entrapment, which can occur if workers lack a safe and accessible way to exit an excavation site.

Depths less than 4 feet generally do not require an additional means of exit, as the risk is considered manageable at that level. This rule is part of a broader set of safety regulations aimed at minimizing hazards associated with excavation work. Thus, the 4-foot requirement underscores the importance of preparedness and safety in construction environments.
