At what trench depth are ladders required for exiting?

3 feet
4 feet
5 feet
6 feet

The correct answer is: 4 feet

Ladders are required for exiting trenches that are deeper than 4 feet due to safety regulations established by the Occupational Safety and Health Administration (OSHA). This is to ensure that workers have a safe and effective means of egress to prevent falls and provide a quick exit in case of emergencies. The requirement is based on the understanding that as trench depth increases, the risks involved also rise, making it essential to have secure access points. In the context of trench safety, if a trench is 4 feet or deeper, it could present significant hazards related to cave-ins, and having ladders available allows for quick access to the surface. Ladders must typically be placed so that they extend at least 3 feet above the surface of the trench to provide a safe handhold for workers exiting the trench. This regulation is a critical component of workplace safety practices in construction environments.
