The Suspension Trauma Safety Strap was designed to help a worker overcome the potential negative health impacts of suspension trauma (otherwise known as Orthostatic Intolerance). This condition can occur when a person remains suspended at height (after a fall) for even short periods of time. Suspension in a harness may cause blood to pool in the veins of the legs which can result in unconsciousness; if not rescued promptly, serious injury or death may occur. The Suspension Trauma Safety Strap is designed to prevent suspension trauma while a worker is awaiting rescue. The Suspension Trauma Safety Strap allows the worker, who is suspended, to stand up in their harness and to relieve the pressure being applied to the arteries and veins around the top of the legs. The continuous loop design allows both sides of the harness to relieve the pressure being applied to the legs. The strap accommodates either having one foot or both feet in the loop at a time – it will relieve the pressure to both sides with just one foot in allowing for added movement of the legs. The strap allows for increased comfort, balance and improved circulation in the legs while suspended and waiting for rescue.
EM-385 Regulation [21.I.06(3)]
