Section 296-78-56511 - Head rigs and feed works(1) A clear walkway must be provided along the upper side of the log deck and around the head rig unless an overhead walkway is provided.(2) The sawyer must be primarily responsible for the safety of the carriage crew and off-bearers. They must exercise due care in the operation of the carriage and log turning devices.(3) Feedworks and log turning control levers must be arranged so that they may be securely locked when not in use and must be guarded against accidental contact.(4) A positive means must be provided to prevent unintended movement of the carriage. This must involve a control locking device, a carriage tie-down, or both.(5) An emergency control or equally effective means must be provided so that the sawyer may stop the head rig section of the mill without leaving the operator station.(6) An effective method of disengaging the head rig saws from the power unit must be installed on all head rigs where the power unit is not directly controlled by the sawyer. The saws must be disengaged from the source of power while repairs or changes are made.(7) A shield of lexan, makrolon, merlon, plestar, or equivalent transparent material, must 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.(8) Safety glasses, safety shields or other suitable eye protection must be provided for and use by head rig off-bearers.Wash.
