WAC 296-307-28018

What requirements apply to guarding pulleys?

(1) Unless guarded by location, pulleys must be guarded according to WAC 296-307-28046 and 296-307-28050 through 296-307-28060. Pulleys serving as balance wheels (e.g., punch presses) on which the point of contact between belt and pulley is more than 6 feet 6 inches from the floor or platform may be guarded with a disk covering the spokes.
(2) If the distance to the nearest fixed pulley, clutch, or hanger is equal to or less than the width of the belt, then you must provide a guide to prevent the belt from leaving the pulley on the side where insufficient clearance exists.
(3) Where there are overhanging pulleys on line, jack, or countershafts with no bearing between the pulley and the outer end of the shaft, you should provide a guide to prevent the belt from running off the pulley.
(4) Pulleys with cracks, or pieces broken out of rims are prohibited.
(5) Pulleys must be designed and balanced for the operating speed.
(6) Composition or laminated wood pulleys must not be installed where they are likely to deteriorate.
