I am a climber, mainly just because at this time in my business we are too small to afford a bucket truck, and that huge insurance that goes with the truck. Also my dad was seriously injured from a bucket truck, when the boom snapped in half. He fell about 50 feet on his head. They say that the boom was not ex rayed, to reveal cracks. The company he worked for cut a lot of corners in those days.
This may be a message to some of you guys that are in small to medium sized tree businesses. To never ignore safety regulations like that one. Your workers are worth the extra money you will need to spend.
