(a) Press brakes, mechanically or hydraulically powered, shall be guarded in a manner that will accomplish the following:
(1) Restrain the operator(s) from 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 operation.
(b) Devices that will accomplish (a)(1), (2) and (3) above include but are not restricted to those listed below:
(1) Presence-sensing device.
(2) Holdout or Restraint Device.
(3) Pullout Device.
(4) Two-Hand Control Device (see 4193(e)).
(5) Type A or B Gate or Movable Barrier Device.
(6) Fixed Barrier Guard (see 4207).
(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 operator shall be qualified, and
(B) The operator maintains a safe distance from the point of operation through the use of hand tools or the size and/or shape of the material being worked so that the operator's hands never enter the point of operation, and
(C) Only general-purpose press brakes with general-purpose dies are used.
(1) Two-hand inching devices shall be used on special-purpose presses for set-up work and adjustment of the press. [See 4193(d)].
(2) General-purpose presses shall be inched for set-up work and adjustment by a single control 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 comply with Section 4194.
(g) Air controlling equipment shall comply with Section 4195.
(h) Hydraulic Equipment. The maximum designed working pressures in any hydraulic system on a press-brake shall not exceed the safe working pressure rating of any component used in that system.
(i) Brakes. Friction brakes for stopping or holding a slide movement shall comply with Section 4200(a).
