1. Getting hit by an implement (stones, weights, hammers).

This is worst of all possible injuries so pay attention to the direction you are being give by an experienced thrower.
a. When you are on the field be aware of what's going on around you.
b. When you're not actually throwing, stand near the edge of the field and keep the throwers in front of you.
c. There is no excuse for checking your email, browsing the web, etc. on your mobile phone while you're on the athletic field. NONE.
d. Be aware of where an implement might go if the thrower inadvertently releases it and that DOES happen. There is an area called "The Kill Zone". Don't sit or stand there.
e. When you hear "Heads up!!" it means an implement is quite possibly heading your way. Look around to see what's going on.
f. Stay away from throwers taking practice throws, hammer winds, caber pulls, and such. Think of walking into a propeller blade like in Indiana Jones.

2. Getting hit by a caber

This is serious business and you do not want this to happen to you or anyone else by your fault.
a. When the call is given "Caber up!!" that means the caber is upright and means the same thing as "Heads up!!"
b. Unless you are the thrower or judge, never stand near the thrower within the length of the caber. This means if the caber should fall, you will be outside of its range.
c. A caber can bounce up after hitting the ground. If it bounces up and strikes you in the privates you may be sing soprano. If the bounce takes the caber up into your face, that's very bad.
d. A falling caber cannot be caught nor can it be outrun. You must side step out of its way.
e. If the judge tells you to drop the caber and get out of the way, DO IT!
f. When carrying the caber to and from, never drop your end and be aware of what the fellow on the other end is doing as well. Leading cause of cracked collarbones.

Just so you don't think I'm making all this up, I personally have seen one particular thrower struck twice by hammers in flight, another thrower struck in the calf by a thrown weight, a judge struck by a falling caber (she forgot the rule about not try to outrun the caber), and a thrower struck in the mouth by a bouncing caber that knocked out a few teeth. That's all that come to mind at the moment. There are many reported injuries on the various Highland Athletics website forums relating sheaf forks to the knees, thrown weights to the skull, and other grim injuries.

Be careful out there and keep your mind on what's going on.
