§4187. Rolls.

(a) The in-running side of the rolls shall be protected with a fixed or self-adjusting barrier so arranged that the material can be fed to the rolls without permitting the fingers of the operator to be caught between the rolls or between the guard and the rolls, or

(b) The control device for the rolls shall be of the constant contact type and shall be so located as to prevent the employees from contacting the danger zone, or

(c) The prime mover shall be equipped with an effective brake and there shall be installed across the front of the rolls at approximately knee height a control bar, lever or other device which when actuated will stop the motor and apply the brake.

NOTE: (1) The intent of this section is primarily to achieve point of operation guarding as required by Subsection (a) above. Where, because of work procedures or other valid reasons, the requirements of Subsection (a) cannot be achieved, the requirements of Subsection (b) shall control. Where neither the requirements of (a) or (b) can be achieved, compliance with Subsection (c) shall then be mandatory.

NOTE: (2) In those instances where there are other orders covering specific rolls, those orders shall prevail over those contained in this section.

EXCEPTION: Rolls which do not expose any employees to a point of operation hazard.
