Firing Range Safety

Range safety can be a complex issue.  Whether it’s a multi-million dollar indoor or outdoor facility, a piece of land privately owned, or the forests and fields where recreational hunting takes place, anywhere a firearm is discharged is considered a range.  Accordingly, the basic safety rules associated with safe firearms discharge apply.  CESI is able to evaluate cases of liability, neglect or negligence, and determine the cause of a range incident where injury or property damage has occurred.
