In a deep trench, what is required for rapid exit?

• A. A ladder
• B. A rope
• C. A scaffold
• D. A winch

Answer: (A)

Having a safe means of exit in a deep trench is essential so workers can get out quickly in an emergency. A ladder provides the quickest, most reliable way to climb from the bottom to the surface, keeping both hands free and allowing a secure ascent even if the trench edge is slick or crowded above. Ropes can be harder to grip securely under load and may slip, making a rapid exit less safe; a scaffold isn’t designed for immediate egress from a trench; and a winch is meant for lifting materials, not for climber safety. So, a ladder is the best choice to ensure rapid escape.
