70 .         Saws for rip sawing

                An owner shall comply with the following provisions: — 

            (a)         The portion of a saw below the saw table shall be enclosed in such manner as to prevent accidental contact with that part of the saw.

            (b)         Provisions shall be made, when maintenance work such as inserting, changing or sharpening saw blades is being carried out, for the prevention of the inadvertent descent of the frame and the falling of elevated pressure rolls.

            (c)         Guards, satisfactory to an inspector, shall enclose the band-wheels, the return side of the saw blade and as much as practicable of the cutting side and counterweights shall be enclosed for the full length of travel.

            (d)         Saw blades shall be securely guarded on the top and at the sides, and there shall be a sturdy riving knife firmly attached behind each saw, and the knife shall extend above the table at least two-thirds the height of the saw and its leading edge shall not be further than 15 millimetres from the saw at any point.

            (e)         There shall be provided a means that prevents press rolls from falling after they have been raised for maintenance work such as saw packing adjustment, the saw blades shall be securely guarded on the top and at the sides, and — 

                  (i)         a sturdy riving knife at least as thick as the saw kerf shall be attached behind each saw; or

                  (ii)         an anti-kick-back device such as suspended fingers shall be arranged to cover the full width of the feed opening,

                except that in the case of stub edgers installed before the date of promulgation of this regulation it shall not be mandatory to fit an anti-kick-back device or riving knives; and where a stub edger is used, there shall be a sturdy fence faced with not less than 225 mm x 75 mm timber at the end of the infeed rollway, the area between the edger and the fence shall be signposted as a danger area not to be entered while the edger is in operation, and the feed to a stub edger infeed rollway shall be interconnected to the rollway drive in a manner that prevents the rollway, inadvertently through minor electrical or pneumatic failure or otherwise, from feeding a flitch or board towards the edger.

            (f)         The operator shall either be located outside the arc of trajectory of any timber that could be thrown by the saw or protected to the satisfaction of an inspector.

            (g)         There shall be a sturdy riving knife firmly attached behind the saw projecting above the saw table at least two-thirds the height of the saw and having its leading edge not more than 15 millimetres from the saw at any point; the riving knife shall be of spring or alloy steel having a thickness not less than one gauge less than the saw blade and on No. 1 benches the width of the riving knife shall be not less than 65 millimetres at bench top level.
