				  substitute for mechanical shifters, they must be big enough for employees to
				  grasp them securely. Poles must be smooth and preferably of straight grain
				  hardwood, such as ash or hickory. The edges of rectangular poles should be
				  rounded. Poles should extend from the top of the pulley to within approximately
				  40 inches of the floor or working platform.

				  practical, belt perches such as brackets, rollers, etc., must be used to keep
				  idle belts away from the shafts. Perches should be substantial and designed for
				  safe belt shifting.
(6) Belts that
				  must be shifted by hand and belts within seven feet of the floor or working
				  platform that are not guarded according to WAC
