11. Paragraph (h) Tree Harvesting
* * *
e. Paragraph (h)(2)(iv) - Spring poles. The standard requires
that when a spring pole or other tree under stress (hereafter collectively referred to as
spring poles) is cut, no employee other than the feller shall be closer than two tree
lengths when the stress is relieved.
(1) Spring poles are danger trees and the requirements of paragraphs (h)(1)(vi) and
(vii) must be followed to minimize exposure to hazards when felling danger trees. These
requirements include felling danger trees by using mechanical means or other methods that
minimize employee exposure to the hazards associated with the danger tree. Any employee
cutting spring poles must have his body and chain saw in the clear when the stress in the
spring pole is released.
(2) Because of the inherent dangers of spring poles, OSHA is also stressing that only
trained workers are allowed to fell spring poles (paragraph (i)). This training includes
recognition of the hazard associated with spring poles (i.e., extreme stress on the entire
tree), as well as the methods for dealing with spring poles. This training should stress
that the preferred method of dealing with spring poles is to avoid them where possible
(i.e., mark them and not work within two tree lengths of them), rather than felling or
removing them. However, if avoidance is not possible, training should emphasize that the
safest way to remove spring poles is by machine.
(3) Where employees are trained in safe felling techniques for spring poles and where
the employer provides the necessary reinforcement of safe work practices through regular
safety and health meetings and spot checks, the potential for death and injury in felling
spring poles will be greatly reduced.
