Section 45.48 - Trim saws

(a) Pneumatic overhead trim saws and undercutting trim saws shall be guarded with a barricade of planking two inches or more in thickness bolted to 4 by 4 inch posts. The barricade may either be suspended from the roof by chains or cables, or may be bolted to the frame of the machine. This guard shall be placed not more than 12 inches from the trim table, unless large timber requires a greater distance.

(b) A barricade, similar in construction to that required in subsection (a), shall be provided in the rear of each overhead trim saw. The guard shall be constructed so as to afford complete protection to anyone working or passing the trimmer.

(c) The end saws on all overhead trimmers shall be fenced off or otherwise guarded from contact.

(d) In front of each overhead trim saw, not less than 24 inches from the front edge of the saw and not more than 12 inches above the trim table, there shall be installed a bar or rod connected with the driving mechanism of the conveyor so that the striking of the bar or rod by any body of material automatically stops the conveyor and prevents the passage of the body into the saws. A rope which may be reached by a man going into the saws shall be accepted, in leiu of a bar or rod, if a clearance of more than 12 inches is desired.
