I know for a fact that municipal governments that practice safety in the ( outside grounds maint.) workplace has very little accident or death rates compare to the private sector. I would think that if we had some kind of law to make a tree company of 2 or 3 employees or more to be more involved in safety like taking classes one a mouth or in-house training of some sort, etc., this could really reduce the rate tremendously. Nobody shouldn't have to die or suffer injury on the job.
