Section R. 408.12331 - Two-hand controlsRule 2331.
(1) A 2-hand control shall require the application of both hands to operate the press and shall require concurrent pressure on both controls until a point is reached in the downward stroke where the die opening is such that the operator cannot remove their hands and place them within the point of operation. Removal of 1 or both hands, before the closing portion of the cycle, shall either stop the slide or return the slide to its starting position.(2) Two-hand controls for single-stroke operation, manufactured and installed on or after August 31, 1971, shall be designed to require release of all operator's hand controls before a second stroke can be initiated.(3) Controls for more than 1 operating station shall be designed to be activated and deactivated in complete sets of 2-hand controls per operating station, by means capable of being supervised by the employer.(4) If foot control is provided, the selection method between hand and foot control shall be separated from the stroking selector and shall be designed so that the selection may be supervised by the employer.(5) A 2-hand control is a mechanically, pneumatically, or electrically controlled system.(6) A 2-hand control shall be installed to prevent "bridging" controls, so that it can be operated by 2 hands only.(7) In a press operation requiring more than 1 operator, a set of 2-hand controls shall be provided for each operator. However, a foot control may be used with 2-hand controls if arranged to operate concurrently (otherwise, no cycle) and if the operator is not exposed to the point of operation.(8) If each of the operating stations is provided with a lockout arrangement, provisions shall be made to prevent an unintentional press cycle when all of the operating controls are locked out.Mich.
