This is not something which can happen to homeowners only during a tree cutting operation, this is the real deal! If you as an arborist choose to put yourself in a poor work position before you execute your work, you too can have an accident like this. Please educate yourself and train yourself to be safer, and it all starts with attitude!!!!!
