Minimises and often eliminates potential safety issues if the lanyard becomes caught while worn. Providing it is positioned correctly, the clip will automatically break off once the tension threshold is reached. Various positioning will affect the tension threshold. Many organisations with strict Occupational Health & Safety rules will often enforce all lanyards to comply with this design feature. Auto release breakaway clips are best positioned near the swivel hook or a little further away from the metal clip. If it is positioned behind the neck instead, a greater tension threshold would be required for the release.
