§4263. Hot and Cold Chamber Machines. Helpers Protection.

Where a helper is employed, his position shall be protected by:

(a) A fixed barrier guard with controls. The control may be foot-operated and shall be interlocked with the primary control so that the machine cannot be started while the secondary control is activated. If the secondary control is activated during the closing cycle, the closing cycle will stop or reverse; or

(b) A sliding gate guard which when closed will prevent contact by the helper with the die. This gate shall be interlocked with the primary control system so that the machine cannot be started while the gate is open and if the gate is opened while the die is closing, the closing cycle will stop or reverse; or

(c) Two-hand controls connected with the primary controls and requiring simultaneous use of both hands of the helper before the machine can be started. Removal of one or both hands during the closing cycle will stop or reverse the closing cycle; or

(d) A single control of the constant pressure type connected with the primary controls. This control shall be located at such a distance from the parting line of the die that the helper cannot reach into the die at the parting line with his free hand. Removal of the hand from the control during the closing of the die will stop or reverse the closing cycle.
