What is the maximum arresting force allowed in a personal fall arrest system?

The maximum arresting force allowed in a personal fall arrest system is established to ensure the safety of workers who may fall while working at heights. The correct answer, which specifies a maximum arresting force of 1,800 pounds, aligns with the regulations set forth by OSHA. This limit is crucial as it is designed to minimize the risk of injury to the worker during a fall.

When a fall occurs, the fall arrest system must be able to stop the fall within a specified distance while exerting a force that does not exceed this limit on the body of the individual using the system. Exceeding this arresting force could result in severe injuries, such as spinal damage or other life-threatening injuries, as the sudden stop could place an overwhelming strain on the person's body.

The other options present higher limits, which do not conform to the standard for personal fall arrest systems. The regulations emphasize not only the effectiveness of the system to prevent falls but also the essential aspect of ensuring that workers are protected from excessive forces that can lead to serious injury. Therefore, 1,800 pounds is recognized as the safe maximum limit, promoting both fall protection and worker health in the construction industry.
