If I'm not mistaken tree stand accidents are the #1 cause of hunter injury by far. The best way to avoid tree a tree stand injury is always wear a full body harness, when climbing up and down the tree and while sitting in your stand. As for shooting accidents these are rare but accidents do happen, know your weapon and always handle it safely, wear your orange and you probaly will never have a problem. Like mentioned before, driving to 7/11 is much more dangerous than hunting. Good Luck
