§ 9.84. Guarding bakery machinery.
(a) Each dough brake shall be provided with either a foot-operated belt shifter or a guard in front of the rolls so arranged that the striking of the guard by the hand of the operator will stop the machine. These devices shall be so located that the operator can stop the machine without moving from the normal operating position.
(b) Each cone on a macaroni kneader shall be provided with a guard which will protect the operator on the nip or intake side of the cone. Such guard shall completely cover the intake side of the cone including the nip point. No dough shall be removed from any macaroni kneader pan while the pan is in motion under power. Dough adhering to cones shall not be removed while the kneader is in motion under power.
(c) Each nontilting type of dough mixer shall be provided with an interlocking device and cover so arranged that power cannot be applied to the agitator unless the cover is within three inches of complete closure.
(d) Each tilting type dough mixer shall be provided with one of the following devices:
(1) An interlocking device and cover so arranged that power cannot be applied to the agitator unless the cover is within three inches of complete closure.
(2) An automatic power cutoff which will cut off all power from the agitator when the bowl is tilted more than three inches from full closure. A substantial stationary cover shall be provided which will close the bowl when it is in the mixing position.
(e) An auxiliary device, in connection with either the interlocking device or the automatic power cutoff for operating the agitator when the bowl is in the tilted or unloading position shall be accepted, if such device functions only when the hand of the operator is on the power control.
(f) None of the provisions of this section shall be construed as applying to cake dough mixers or icing mixers.
