A Direction of fall
B Escape path (escape routes)
–
Establish escape paths for each
worker – approx. 45° diagonally
opposite to the direction of fall
–
Clear escape paths, eliminate
obstacles
–
Put down tools and equipment at a
safe distance – but not on the
escape paths
–
When felling, stand only to the side
of the falling trunk and only move
back laterally onto the escape path
–
Plan escape paths on slopes
parallel to the slope
–
When walking away along the
escape path, watch out for falling
limbs and watch the top of the tree.
Preparing work area at base of tree
–
First clear the tree base and work
area from interfering limbs and
brush to provide a secure footing.
–
Carefully clear the base of the trunk
(e.g., with an axe) – sand, stones
and other foreign objects will blunt
the saw chain
–
Remove largest buttresses: first the
largest buttress – saw first vertically,
then horizontally – only if the tree is
in sound condition
Felling notch
Preparing the felling notch
The felling notch (C) determines the
direction of fall.
Important:
–
Make a felling notch at right angle to
direction of fall
–
Saw as close to the ground as
possible
–
Cut to a depth of approx. 1/5 to 1/3
of the diameter of the trunk
