What is the maximum arresting force that body harnesses must limit to?

The correct answer reflects the maximum arresting force that body harnesses must limit to, which is established to ensure the safety of personnel working at heights. This standard is grounded in safety regulations that aim to minimize the risk of injury during a fall.

Harnesses are designed to distribute the forces exerted on a person during a fall over a broader area of the body, reducing the risk of suspension trauma or other injuries. A limit of 1,800 pounds for maximum arresting force is a widely accepted safety threshold that considers physiological factors and the potential for injury.

Using a higher limit would pose a higher risk in terms of the potential for serious injuries caused by the forces experienced during a fall. Therefore, it is critical that safety equipment, including body harnesses, adhere to these established guidelines to provide adequate protection without exceeding safe limits.
