Answer :
Final answer:
The minimum breaking strength for lanyards and vertical lifelines in a personal fall arrest system is typically specified at 5,000 pounds (22.2 kN) according to industry safety standards like those from OSHA.
Explanation:
In a personal fall arrest system, lanyards and vertical lifelines must have a minimum breaking strength specified by industry safety standards. These standards are crucial to prevent falls and ensure the safety of individuals who work at heights. The equipment must be strong enough to withstand the forces applied during a fall, which includes the weight of the person and the dynamic forces incurred during the arrest of a fall.
Based on the references provided, to calculate specific forces on anchors, lanyards, or ropes, a physical understanding of the forces involved and the application of Newton's laws of motion are required. For instance, a rope should support a minimum breaking strength proportional to the user's weight to ensure it does not snap under tension.
To address the specifics of breaking strength: in industrial or construction scenarios, typically, a personal fall arrest system including lanyards, and vertical lifelines require a minimum breaking strength of 5,000 pounds (22.2 kN) to meet the standards set forth by organizations such as the Occupational Safety and Health Administration (OSHA) in the United States.
