Final answer:
Connectors in personal fall arrest systems must support at least 5,000 pounds (22.2 kN) of force to ensure safety and reliability in preventing injury or fatality during a fall.
Step-by-step explanation:
The student is asking about the strength requirements for connectors used in personal fall arrest systems. These connectors, such as D-rings and snap-hooks, are critical safety components designed to arrest a fall and thus must be very strong and compatible with other parts of the system. According to safety standards, these connectors must be capable of supporting at least 5,000 pounds (22.2 kN) of force, ensuring that they can endure the stress and impact forces involved during a fall without failing.
This standard ensures the safety and reliability of the fall protection equipment, providing peace of mind that the equipment will perform as needed to prevent serious injury or fatality in the event of a fall.
