Rule 5138. (1) A buzz saw shall have a hood-type guard which covers the upper half of the blade, arbor, and nut at all times. The lower part of the blade shall be guarded by 1 of the following: (a) A fixed or adjustable barrier guard which protects the operator from inadvertently coming into contact with the saw teeth. (b) A self-adjusting guard which will prevent employee exposure to the front of the saw blade by dropping onto the workpiece before the blade starts the cut and remaining in contact with the workpiece until the saw table returns to the forward position. (c) Movement of the saw table into the saw by use of constant pressure controls located so that the operator cannot come into contact with the saw blade. (d) Any other type of guarding that provides equal protection.
