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.
