Quick Release Harnesses; Loads on a High Line

Allfree, S, Collins, L & Onions,C



This study examines the loads associated with positioning a Rescuer on a Quick Release Harness (QRH) on a high line in moving water. Testing was conducted at water speeds of 0.6 – 2.4m/s, typical of those encountered during water related rescues. A Rescue Randy Combat Challenge Manikin (65kg) was positioned on a QRH from a high line and an in-line load cell utilised to collect force/time data. The findings identify operational water speeds for positioning Rescuers in water using a QRH. The study contributes to the work by Onions and Collins in their earlier investigations and the understanding the loads placed on high lines during rescues by the emergency services.
