Universal Citation: MI Admin Code R. 408.12341

Current through Vol. 24-16, September 15, 2024

Rule 2341.

(1) A presence sensing device shall be designed and installed so that when the operator's hands or another part of the body disturbs the sensing field, the downward travel of the slide is prevented or stopped. This device shall not be used as a tripping means.

(2) Equipment shall be installed so that failure of light or photoelectric relay or other energy source makes the press inoperative.

(3) These devices shall not, in themselves, create a physical or organic hazard to the operator.

(4) The safety distance (Ds) from the sensing field to the point of operation shall be greater than the distance determined by the following formula:

Ds = 63 inches/second X TS where:

Ds = minimum safety distance (inches); 63 inches/second = hand speed constant; and

TS = stopping time of press measured when slide has completed approximately half of the downward stroke.

(5) To protect all areas of entry to the point of operation not protected by the presence sensing device, the partial enclosure shall be used and shall not create a pinch point or shear hazard.
