Section 4318 - Planing, Moulding, Sticking, and Matching Machines

(a) Each planing, molding, sticking and matching machine shall have all cutting heads, and saw blades, if used, covered by a metal guard. If such guard is constructed of sheet metal, the material used shall not be less than 1/16 -inch in thickness, and if cast iron is used, it shall not be less than 3/16 -inch in thickness.

(b) Where an exhaust system is used, the guards shall form part or all of the exhaust hood and shall be constructed of metal of a thickness not less than that specified in Section 4318(a).

(c) Feed rolls shall be guarded by a hood or suitable guard to prevent the hands of the operator from coming in contact with the in-running rolls at any point. The guard shall be fastened to the frame carrying the rolls so as to remain in adjustment for any thickness of stock.

(d) Surfacers or planers used in thicknessing multiple pieces of material simultaneously shall be provided with sectional infeed rolls having sufficient yield in the construction of the sections to provide feeding contact pressure on the stock, over the permissible range of variation in stock thickness specified or for which the machine is designed. In lieu of such yielding sectional rolls, suitable anti-kickback devices shall be provided at the infeed end.
