inadvertently reaching into the point of operation, or
(2) Inhibit machine operation if the
operator's hand or hands are inadvertently within or placed within the point of
operation, or
(3) Automatically
withdraw the operator's hands if they are inadvertently within the point of

(7)
An arrangement of stops and holding devices such as a feed table or other
material support, which will assist in positioning and supporting the material
being worked so that the controls can be remotely located. When such stops and
material supports are used, the controls shall be so located that the
operator(s) can not activate the control(s) and reach into the point of
operation.
(8) Any other system of
guards, automatic or semi-automatic feeds, etc., that will allow the material
to be worked and effectively prevent the operator's hand(s) from entering or
being in the point of operation during the die-closing portion of the press
stroke.
(9) When the nature of the
work or size and/or shape of material being worked is such that compliance with
the provisions of Section
4214(b)(1) through
(8) is not practical, the employer shall
ensure compliance with the following:
(A) The

protected against accidental actuation so that the worker can not reach into
the point of operation while inching the press.
(d) Control Reliability [see 4204(a) and
(b)].
(e) Point of operation guards
and devices shall comply with Sections
4207 and
4208 respectively.
(f) Slide counter-balance systems shall
