• A. 3
• B. 4
• C. 5
• D. 6

Answer: (B)

The main idea is that OSHA requires a safe way out of an excavation once it reaches a depth where escaping by climbing the trench wall becomes unsafe. The threshold for needing a ladder, steps, or another safe exit is four feet or more in depth. This keeps workers from having to scramble out of a deeper trench where soil may be unstable or collapse could block a quick exit. A ladder or similar exit provides a controlled, reliable means of egress and reduces the risk of falls or entrapment as the trench gets deeper. Shorter trenches don’t trigger this mandatory exit requirement, though other safety measures may still apply. So, the required depth for an adequate means of exit is four feet.
