Mich. Admin. Code R. 408.12462 - Point of operation guards

Rule 2462.

(1) A point of operation guard shall meet the following design, construction, application, and adjustment requirements:

(a) It shall prevent entry of hands or fingers into the point of operation by reaching through, over, under, or around the guard.

(b) It shall conform to the maximum permissible openings of table 1 and figure 1, except that a barrier guard may have feed holes for the stock, which shall be of such size and distance from the die as to prevent entry of a hand or finger of each operator into the point of operation or nip point.

(c) It shall, in itself, create no pinch point between the guard and moving machine parts.

(d) It shall utilize fasteners not readily removable by the operator so as to minimize the possibility of misuse or removal of essential parts.

(e) It shall facilitate its inspection.

(f) It shall offer maximum visibility of the point of operation consistent with the other requirements.

(2) A die enclosure guard shall be attached to the die shoe or stripper in a fixed position.

(3) A fixed barrier guard shall be attached securely to the frame of the press or to the bolster plate.

(4) An interlocked press barrier guard shall be attached to the press frame or bolster, and shall be interlocked with the press clutch control so that the clutch cannot be activated unless the guard itself, or the hinged or movable sections of the guard, are in position to conform to the requirements of table 1 and figure 1.

(5) The hinged or movable sections of an interlocked press barrier guard shall not be used for manual feeding. The guard shall prevent opening of the interlocked section and reaching into the point of operation prior to die closure or prior to the cessation of slide motion. See R 408.12463(2) regarding manual feeding through interlocked press barrier devices.

(6) The adjustable barrier guard shall be securely attached to the press bed, bolster plate, or die shoe, and shall be adjusted and operated in conformity with table 1 and figure 1 and the requirements of this rule.

Adjustments shall be verified before the press is returned to production operations by authorized personnel whose qualifications include a knowledge of the provisions of table 1 and figure 1 and the requirements of this rule.

(7) A point of operation enclosure which does not meet the requirements of this rule and table 1 and figure 1 shall be used only in conjunction with point of operation devices.
