Tree Strikes
You’re Out
Introduction
Snags are dead or dying trees. Hazard trees can be dead, dying or green trees that are
unstable. Over the years many people
who have worked in the wood have been killed or injured in accidents involving
hazard trees. On the Plumas, and
elsewhere in western forests, snags are becoming an ever-increasing hazard
after years of draught, fire exclusion, and bug kill. Because of safety concerns, a committee has been formed to study
this problem and develop ways to help employees become more aware of this
issue. Results of a forest survey
indicate that many people have had accidents or close calls due to snags and
other hazard trees.
This pamphlet gas been developed, with information from the
National Snag Hazard Task Force and others.
We hope to increase awareness and educate employees about the dangers of
hazard trees and how to work safely in the woods. The information in this pamphlet will help employees to:
1.
Recognize indicators that will identify hazard trees.
2.
Identify what work situations could put employees in danger
(Watch-Out Situations)
3.
Apply appropriate safety guidelines.
Fact: There
are several million snags on the Plumas.
Fact: All
these snags will come down.
Question:
Will you be under one when it comes down?
Hazard Tree Indicators
- Numerous
down trees.
- Leaning
trees.
- Dead
or broken tops and / or limbs hanging in the trees.
- Absences
of needles, bark, or limbs.
- Possible
of rot indicated by conks, broken tops, basal scars, cat faces, numerous
down limbs, ants, abundance of woodpecker holes.
- Stump
holes burning in the area.
- Smoke
or fire burning in the base or tops of either dead or live trees may
indicate rot and / or weakening of tree.
Watch Out Situations
- Snags
are falling or have fallen in work area.
- The
area is occupied by trees that are susceptible to rot, especially white
fir and old oak trees.
- Working
or taking a break in a hazard area.
- Working
in a hazard tree area for more than a few minutes.
- Working
in hazard tree area during windy or potentially windy situations.
- Working
in an area with trees that have been burning for an extended period.
- Tailgate
safety session did not include discussion of snags.
- Lookouts
are not posted or do not have communications in a hazard tree area.
- Becoming
complacent in a hazard tree area.
- Too
many snags for posted lookouts to keep track of.
- Tree
within fire will fall over control line.
- Escape
routes pall through hazard tree area.
- Safety
Zones exposed to hazard trees.
- Parking
in hazard tree area.
- Crew
fatigued from being on shift for an extended period.
- Working
around heavy equipment or tree felling operation in a hazard tree area.
- Unable
to see top of trees.
- Steep
slope with hazard trees above you.
- Nighttime
work in area not scouted in daylight.
Safety Guidelines
- Assess
snag hazards before parking, taking breaks, or sleeping.
- Make
sure that employees wear 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.
