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

The requirement from OSHA states that ladders or steps must be provided in trenches or excavations that are 4 feet deep or more. This regulation is crucial for ensuring the safety of workers who may need to exit the trench quickly in an emergency situation. When trenches reach this depth, the risk of cave-ins and falls increases significantly, making safe access and egress a priority.

By enforcing this requirement, OSHA aims to minimize hazards associated with working in deep excavations. Proper exit provisions such as ladders or steps allow workers to maintain their safety and manage risks effectively while performing their tasks. Therefore, the correct answer reflects the necessary safety standards mandated by regulatory authorities for worker protection in construction environments.
