Can ordinary ropes replace fall arresters

Let's think about this question, can ordinary ropes replace fall arresters? At present, many high-altitude workers still adopt the most primitive safety protection method of hemp rope binding, which means that there is hemp rope traction after the worker slips and falls, and it will not cause accidents such as falling to the ground. However, is this the reality?

From a physics perspective, a high-altitude fall will continuously accelerate with a gravitational acceleration of 9.8M/s, and the faster the speed, the higher the impact force. In this case, it is likely to face two situations. The first is that a long fall distance will generate a large impact force, causing the hemp rope to break and resulting in casualties. Secondly, the instant straightening and braking of the hemp rope transfers all kinetic energy to the human body, which cannot withstand the instantaneous impact force and causes casualties.

In summary, accidents involving injuries and fatalities do not necessarily occur when falling to the ground. The height of the fall determines everything, and the longer the distance, the greater the impact force generated, resulting in greater harm. Fall arresters use the principle of ratchet and pawl engagement self-locking, similar to car seat belts, which can brake within a short distance of 0.2 meters, and the impact force generated will not cause harm to the human body. Therefore, ordinary ropes cannot replace fall arresters.
