Michigan Residential Builders License Practice Test

What is the maximum arresting force allowed on an employee when using a personal fall arrest system with a body harness?

1. 1200 LBS

2. 1500 LBS

3. 1800 LBS

4. 2400 LBS

The correct answer is: 1800 LBS

The correct answer indicates that the maximum arresting force allowed on an employee when using a personal fall arrest system with a body harness is 1800 pounds. This standard is set to ensure safety and minimize the risk of injury during a fall. When an employee falls, the fall arrest system must function effectively to stop the fall in a controlled manner. The limit of 1800 pounds is based on safety testing and engineering principles that balance the need for effective arresting force while also minimizing the potential for injury such as suspension trauma or other impact-related injuries. If the force exceeds this threshold, it could result in severe injury or even fatality. In contrast, the other choices present maximum force limits that exceed the established safety parameters and would not comply with OSHA regulations designed to protect workers in the construction industry. Ensuring that the maximum arresting force does not surpass 1800 pounds is critical to maintaining a safe work environment when using personal fall arrest systems.
