What is the minimum tensile strength required for an emergency escape harness?

Minimum tensile strength for an emergency escape harness is set to withstand the peak dynamic load generated during an escape fall. The forces from a fall are not just body weight; deceleration can create several kilonewtons of load, so the harness and its hardware must be rated above normal working loads to avoid failure. Therefore, the minimum required breaking strength is 19.5 kN (about 4,400 pounds-force). This provides a safety margin for shock loading and system deceleration. Values much lower, like 1.33 kN, would not tolerate fall forces; higher numbers such as 26 kN or 36 kN exceed the minimum and may appear in scenarios with stricter or heavier-duty requirements, but the question asks for the minimum. Choosing equipment rated at least 19.5 kN helps ensure the escape harness remains intact under emergency loading.
