Where an exhaust system is used, the hood of the exhaust system shall will be construed as comprising all, or part, of the guard.

(2) Disc sanders.

Disc sanders shall will have a guard so arranged to enclose the periphery and back of the revolving disc, except such portion of the face of the disc above the table (if table is used) as may be required needed for the application of the material to be finished. Where an exhaust system is used, the hood of the exhaust system shall will be construed as comprising all, or part, of the guard.

(3) Belt sanders.

Belt sanders shall will have both pulleys guarded in such manner as to guard the points where the belt runs onto the pulleys. The edges of the unused run of the belt shall will be guarded.

(4) Feed rolls of self-feed sanding machines.

Power-driven feed rolls, when exposed to contact, shall will be guarded so as to prevent the hands of the operator from coming into contact with in-running rolls at any point.

(G) Wood shapers.

(1) Guarding.

(a) Cutting heads.

(i) The cutting heads of each wood shaper, hand-fed panel raiser or other similar machine, not automatically fed, shall will be guarded. The diameter of circular shaper guards shall will be not less than the greatest diameter of the cutter.

(ii) When single cutter knives in shaper heads are used, the shaper heads shall will be balanced.

(b) Alternate method.

(2) Starting and stopping devices.

All shapers shall will be provided with a spindle starting and stopping device for each spindle.

(H) Tenoners.

Tenoners shall will have all cutting heads or saws guarded. An exhaust hood may comprise part or all of the guard. If such a guard is constructed of sheet metal, the material used shall will be not less than one-sixteenth inch in thickness, and if cast iron is used, it shall will be not less than three-sixteenths inch in thickness.

(I) Lathes.

Each profile and swing-head lathe shall will have the cutting head guarded. An exhaust hood may comprise all, or part, of the guard.

(J) Veneer machinery and equipment.

(1) Vats and soaking pits.

(a) Guarding.

Sides of vats and soaking pits shall will extend to a height of not less than thirty-six inches above the working floor level. When loading or unloading operations are performed from the sides and/or ends of vats and soaking pits, standard guard railing and toeboards shall will be installed.
