Section 408.12331. Two-hand controls.

(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 his hands and place them within the point of operation. Removal of 1 hand 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 may be a mechanically, pneumatically, or electrically controlled system.

(6)   A 2-hand control shall be installed to  prevent  "bridging"  controls, and 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, provision shall be made to prevent an unintentional press cycle when all of the operating controls are locked out.
