English to French Tech/Engineering Safety Job title

Je connais le sens de "bottoming out" quand on parle d'atteindre le fond du baril, d'avoir épuisé ses options, etc. mais, ici, dans un contexte de chute de hauteur, je désire vérifier s'il existe un terme consacré. Voici le paragraphe complet pour plus de contexte.

Bottoming out occurs when a falling worker hits a lower level, the ground or other hazard before the fall is fully arrested. This means the total fall distance is greater than the distance from the work surface to the next surface below. Personal fall arrest systems must be planned to provide sufficient clearance to prevent the worker from contacting anything located below. When determining clearance one needs to consider the lanyard length, deceleration distance, harness stretch, worker height and a safety factor of 3 feet.
