Section 4261 - Hot Chamber and Cold Chamber Machine ControlsEvery hot and cold chamber die casting machine shall be equipped with one of the following controls:
(a) Two-hand controls requiring the concurrent use of both hands until the die is completely closed. Removal of either or both hands during the closing of the die will stop or reverse the closing cycle, or(b) A single control of the constant pressure type. This control shall be located at such a distance from the parting line of the die that the operator 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, or(c) A sliding gate guard which when closed will prevent contact by the operator with the die. This gate shall be interlocked with the control system so that if the gate is opened prior to the completion of the closing cycle, the closing cycle will stop or reverse, or(d) Any other device that will provide protection equivalent to that of (a), (b) or (c).(e) On cold chamber machines two-hand controls requiring the concurrent use of both hands until the die is within 2 inches of complete closing. This control shall be of the type that has an interlocking limit switch that maintains a closed circuit for the last 2 inches of the closing cycle. Removal of either or both hands before the activation of the limit switch will stop or reverse the closing cycle.Cal. Code Regs. Tit. 8, § 4261
