Personal fall arrest systems, work-positioning equipment, or fall restraint systems must be used when an employee is working on a pole, tower, or similar structure more than ? above the ground.

• A. 3 feet
• B. 4 feet
• C. 5 feet
• D. 6 feet

Answer: (D)

When working on tall structures like poles or towers, there is a height at which fall protection becomes mandatory to prevent serious injury. The required protective equipment—personal fall arrest systems, work-positioning gear, or fall restraint—kicks in when you are more than six feet above the ground. This six‑foot threshold exists because a fall from that height can cause severe injury, and the listed equipment is designed to either stop a fall before you hit the ground or keep you from reaching the edge in the first place. Heights below six feet don’t meet this particular rule, though other safety considerations may still apply depending on the job and site conditions.
