Arborists: look up, stay clear & stay secured.

Michigan Fatality Assessment & Control Evaluation
East Lansing, MI: Michigan State University, Department of Medicine, Occupational and Environmental Medicine, HA#4, 2005 Jan; :1
In Michigan from 2001-2003, 7 arborists have been killed when struck by falling trees or limbs or after falling from the tree while trimming. In order to prevent similar incidents in the future: 1. Develop a work plan. 2. Communicate the work plan to all workers through a job briefing before the work begins. 3. Assign work areas so that the distance between adjacent occupied work areas is at least two tree lengths of the trees being felled. 4. Set up the work area to prevent intrusions. 5. Evaluate trees before they are worked on to be sure they can stand the strain of climbing, rigging, or removal. 6. Plan a clear escape path. A safe escape path is 45 degrees from the sides and back on either side of the tree. Never move away directly behind the tree. Use the chain brake, walk away at least 20 feet and try to put yourself behind a standing tree. 7. Use safe climbing procedures such as breaking or cutting off dead limbs while climbing and placing hands and feet on separate limbs. 8. Communicate struck-by hazards through " voice command & response" : the climber should say, "Stay clear!" and groundworkers acknowledge with, "All clear!" before trees or tree sections are allowed to fall.
