Fall Arrest System
Read and understand the manufacturer's warnings and instructions on how to properly use and adjust the FAS/FBH. Carefully inspect your FAS/FBH before each use and check the expiration date printed on the label. Never use a damaged or expired FAS/FBH.
Do not leave the ground unless you are wearing a FAS/FBH that is properly attached to the tree. A FAS/FBH should be worn and properly attached to the tree from the time you leave the ground until you're back down.
Practise using your FAS/FBH at ground level and before using in the field. With another responsible adult standing by, experience what it feels like to hang suspended in your harness.
