(a) Where necessary to manually push the last loaf through the slicing knives, the operator shall be provided with and shall use a suitable and adequate device by which the loaf can be pushed through the knives without danger to hands or fingers.

(b) The cover over the knife head of reciprocating-blade slicers shall be provided with an electrical control switch so that the machine cannot operate unless the cover is in place.

(c) On slicers with endless band knives, the wiring for the motor shall be so arranged that a brake will be applied each time the motor is shut off, or it shall be so arranged by means of a limit switch that it cannot be run with the side door open. All doors and removable panels to the cutting head shall be either connected to electric switches or shall have no latch openings and be so fastened that they cannot be opened from the outside except through the side door.

(d) When it is necessary to sharpen slicer blades on the machine, a barrier shall be provided leaving only sufficient opening for the sharpening stone to reach the knife blades.
