Final answer:
When a trench is 4 feet or more in depth, there must be a means of egress within 25 feet for worker safety.
Step-by-step explanation:
When a trench is 4 feet or more in depth, a means of egress from the trench must be within 25 feet of lateral travel.
This means that if a worker is inside a trench that is 4 feet deep or deeper, there must be a way for them to exit the trench within a maximum distance of 25 feet.
This requirement is in place to ensure worker safety and to provide a quick and accessible escape route in case of emergencies, such as a collapse or flooding.
When a trench is 4 feet or more in depth, Occupational Safety and Health Administration (OSHA) regulations require that a means of egress, such as a ladder, steps, or ramp, must be provided and located so that a worker does not have to travel more than 25 feet laterally within the trench to reach it. This ensures that in case of an emergency, workers can exit the trench quickly and safely. Furthermore, these escape routes must be maintained throughout the duration of the work to safeguard worker safety.
