Means of egress from trench excavations such as a stairway, ladder, or ramp are required in trench excavations deeper than how many feet?

• A. 2 feet
• B. 3 feet
• C. 4 feet
• D. 5 feet

Answer: (C)

In trench safety, there must be a safe way out as the trench gets deep enough for workers to be at risk. A means of egress such as a stairway, ladder, or ramp is required when the trench depth reaches four feet or more, so workers can exit quickly if hazards develop. This setup helps prevent entrapment and reduces exposure time to potential cave-ins or other dangers. The rule also typically requires the exit to be located within a reasonable distance along the trench (often about 25 feet of lateral travel) to ensure rapid access. So, the depth threshold where egress becomes mandatory is four feet.
