Attachment and lift procedure
Whenever using the crane access method , follow this procedure :
1 . Confirm that the crane access method will be used . Both rescuer and crane operator must agree that this access method is the safest or most practicable to be used .
2 . Confirm that the crane is suitable for the intended purpose . 3 . Select the method the rescue climber will use to tie into the hook .
4 . Attach to the hook . The rescuer must visually inspect , and load test all attachment components before confirming to the crane operator they are ready to be lifted . The crane operator must then visually inspect all components and confirm they are suitable for use and will not be affected by or affect the operation of the crane .
5 . Store excess climbing ropes in bags carried by the rescuer . This is to prevent the climbing lines from being snagged during lifting . Hang the bag at foot height to make it easier to guide through the canopy with the feet . The climbing lines must be long enough for the climber to perform a self-rescue at any point during the operation ( e . g ., if the crane becomes immobile ).
6 . Lift the rescuer up into position above the tree so they can effectively abseil down onto the casualty and conduct a pick-off rescue suspended by the crane hook . At this stage the crane should be isolated .
