  (5) When used, interlocks shall be installed to minimize the possibility of accidental operation or tampering.

  (6) Where more than 1 operator is assigned to a plastic molding machine that is not equipped with interlocked gates and the operator is exposed to a point of operation, or when hazardous motion in or near the point of operation could cause injury, each operator shall be provided with a device that prevents reaching into the point of operation during the closing cycle.

  (7) Two-hand control devices shall be located in a manner to prevent bridging.

 

R 408.16227. Lubrication and maintenanceRescinded.

  Rule 6227. (1) Lubrication of a machine shall be accomplished by 1 of the following:

  (c) An extension pipe leading to an area outside of the guards or away from any hazard.

  (2) Each employee doing the work shall lock out the power source of the machine or equipment to be repaired or serviced if unexpected motion would cause injury. Any residual pressure which would be hazardous shall be relieved before and remain relieved during work by an employee doing the work.

 

 

SPECIFIC EQUIPMENT
