personal protective gear at all times. * Use every day examples to
brief and train employees about what snag hazards look like. *
Consider suspending operations during windy periods. * Allow
adequate time for scouting. * Identify; tree species common to work
area especially those that are more susceptible to heart rot, root
rot, or shallow roots. * Scout for hazard trees and visibly mark or
flag individual and groups of snags that are in or near work areas.
* Post lookouts in areas of known or potential snag hazards. * When
possible, use work tactics which avoid or minimize employees
exposure to snag hazards. * All crewmembers have the responsibility
to speak out when confronted by snag hazards. * Discuss and plan
escape route and safety zone considering vegetation and terrain. *
Assess the height of treetops when planning safety zone and escape
routes. * Fire Safety Zones must be free of hazard tree threat. *
Use extra caution when down hill of hazard trees. It is more common
for trees and debris to go down hill. * When escaping the path of a
falling tree, do not turn your back- Watch the tree as you move out
of its way to ensure you can see any change in its fall or roll
caused by contact, breakage, etc. * Use extra precaution during
night operations. * Determine if the benefit is worth the risk.
