The escape devices for a trench over 4 feet deep MUST be within a MAXIMUM of

• A. 10 feet
• B. 15 feet
• C. 25 feet
• D. 50 feet

Answer: (C)

When a trench is more than four feet deep, having a safe way out within a short distance is essential so workers can escape quickly if conditions deteriorate. The rule requires a portable ladder, stairway, ramp, or other safe means of egress to be located so that a worker can reach it within twenty-five feet of travel along the bottom of the trench. The distance is a horizontal measure to the exit, not a vertical drop. This twenty-five-foot maximum is designed to minimize time to escape and reduce the risk during emergencies such as a cave-in or exposure to hazardous atmospheres. So, twenty-five feet is the correct maximum distance. Distances like ten or fifteen feet would still meet the requirement but aren’t the maximum allowed, while fifty feet would exceed the limit and fail to comply.
