Résumé

When working at heights, fall protection is required. The individual fall arrest system IFAS is made of a full body harness, an energy absorber, a lanyard, a connecting subsystem and an anchor. The energy absorber is the key component that maintains the arrest force at an acceptable level for the user. The safe maximum arrest force is relative the body mass; the safe deceleration is a constant around 10g. The energy to be dissipated during the arrest of the fall is the potential energy: the weight of the falling person (mg) multiplied by the free fall distance (h). Because the body mass varies considerably, two classes of energy absorbers are covered by the CSA Z259.11- 05(R2010) Energy absorbers and lanyards. The actual classes are governed by the body mass but they do not take into account the free fall distance. The users have some difficulties in making a correct selection. A graphical label incorporating the mass and the free fall distance is proposed to simplify the selection.
