WAC 296-78-56511
Head rigs and feed works. (1) A clear
walkway shall be provided along the upper side of the log deck
and around the head rig unless an overhead walkway is
provided.
(2) The sawyer shall be primarily responsible for the
safety of the carriage crew and off-bearers. He shall
exercise due care in the operation of the carriage and log
turning devices.
(3) Feedworks and log turning control levers shall be so
arranged that they may be securely locked when not in use and
shall be guarded against accidental contact.
(4)(a) A positive means shall be provided to prevent
unintended movement of the carriage. This shall involve a
control locking device, a carriage tie-down, or both.
(b) An emergency control or equally effective means shall
be provided so that the sawyer may stop the head rig section
of the mill without leaving the operator station.
(5) An effective method of disengaging the head rig saws
from the power unit shall be installed on all head rigs where
the power unit is not directly controlled by the sawyer. The
saws shall be disengaged from the source of power while
repairs or changes are made.
(6) A shield of lexan, makrolon, merlon, plestar, or
equivalent transparent material, shall be installed between
the sawyer's stand and the head saws in all circular mills. In band mills and chipper type installations, a wire screen of
not less than twelve gauge wire, one-half inch mesh, mounted
in a frame in compliance with chapter 296-806 WAC, Machine
safety, is an acceptable substitute for the type shield
required in circular mills.
(7) Safety glasses, safety shields or other suitable eye
protection shall be provided for and use by head rig
off-bearers.
