(a) All exposed parts of line or countershafting or collars, clutches, cut-off couplings and clutch pulleys seven feet or less above floor or other working level shall be guarded.
(b) Wherever shafting extends over a driveway it shall be enclosed or guarded with a trough guard unless it is located 15 feet or more above driveway or is a part of an overhead traveling crane and does not otherwise violate provisions in this order. See (d) below.
(c) Transmission shafting under benches shall be guarded in one of the following ways:
(1) Completely enclosed.
(2) Guarded by a trough guard enclosing sides and top or sides and bottom as the exposure requires. The sides of the trough shall come within at least 6 inches of the underside of the table, or if the shafting is located near floor, within 6 inches of the floor. In every case the sides of the trough shall extend at least 2 inches above or below the shafting.
(3) Guarded on exposed sides with a rigid shield guard extending from the underside of bench top to 2 inches below bottom line of shafting.
EXCEPTION: Wherever power sewing machines or other similar light machines are operated by shafting under the machine table, such shafting shall be in compliance when the shafting is 20 inches or more horizontally from the vertical plane of the working edge of the bench. When such transmission is so located it constitutes a hazard, it shall be guarded.
