How deep must trenches or ditches be for OSHA to require ladders or steps for adequate exit?

Trenches or ditches must be 4 feet deep or more for OSHA to require ladders or steps for adequate exit. This regulation is in place to ensure safety for workers who may be working in these excavations. The depth of 4 feet is significant because it increases the risk of cave-ins, making it essential to provide a means for workers to quickly and safely exit the trench if needed. The presence of ladders or steps helps to prevent accidents, such as falls, and facilitates prompt evacuation in emergencies. This regulation reflects OSHA's commitment to protecting workers in potentially hazardous environments.
