§4197. Design, Construction, Setting and Feeding of Dies.

(a) General. It shall be the responsibility of the employer to:

(1) Use dies, safety devices and operating methods designed to eliminate hazards to operating personnel, and,

(2) Furnish and enforce the use of hand tools for freeing and removing stuck work or scrap pieces from the dies to avoid requiring the operator or other personnel from reaching into the point of operation.

NOTE: The employer should consider the design and use of dies and feeding mechanisms to eliminate the need of an operator(s) to place his/her hand(s) in the point of operation.

(b) Provision shall be made in both the upper and lower shoes for securely mounting the die to the bolster and slide. Where clamp caps or set screws are used in conjunction with punch stems, additional means of securing the upper shoe to the slide shall be used.

(c) Handling equipment attach points shall be provided on all dies requiring mechanical handling.

(d) If unitized tooling is used, the opening between the top of the punch holder and the face of the slide, or striking pad, shall be guarded.

NOTE: Authority cited: Section 142.3, Labor Code. Reference: Section 142.3, Labor Code.
