Australia Model Code of Practice: Managing the Risk of Falls at Workplaces 10.1: 10.1 Prevent suspension intolerance and train workers for rescue

A person hanging upright in a harness after an arrested fall can suffer suspension intolerance (reduced blood return, fainting, possible renal failure and death), worsened by heat and dehydration, so quick rescue is vital, workers should be able to rescue a fallen colleague using on-site equipment, and relevant workers must be trained in the rescue procedures and in recognising the condition. To prevent it, workers should never work alone when using a harness; harnesses should let legs be kept horizontal; where rescue may take more than five minutes, the harness and connection should allow the legs to be raised near horizontal or workers should carry foothold straps; and workers should be trained to move their legs, push against footholds and move towards horizontal while suspended.
