What is the limit maximum arresting force on an employee when used with a body harness?

• A. 1800 lbs
• B. 900 lbs
• C. 3600 lbs
• D. 1200 lbs

Answer: (A)

Arresting force is the peak load that a fall-arrest system is allowed to transmit to a worker when a fall is stopped. For a worker wearing a full-body harness, the standard limit is 1,800 pounds. This higher limit exists because a harness distributes the stopping load across the torso, hips, and legs and works with energy-absorbing components to keep peak forces from injuring the worker. By contrast, using a simple body belt concentrates force in a smaller area, which is why a much lower limit (1,800 pounds is not applicable there) is associated with belt-based systems. So, when a body harness is used, the maximum arresting force permitted is 1,800 pounds.
