I found on the internet an Accident Alert from OSHA from a Weed-eater accident that happened to a crew of workers.  Using actual examples of accidents is a very effective way of training on the possible accidents that can happen in the field.  Specifically, this addresses objects being thrown at someone other than the operator, a risk you all probably come across.  Rocks, broken glass, limbs or twigs, or other objects can be thrown from trimmers into people, vehicles, glass or other objects resulting in an injury or property damage and an insurance claim.
