§ 47.343. Machines.
(a) The machines listed in this section are those of known danger for which efficient guards are in common use. Other machines may be added from time to time as practical methods of guarding are devised.
(b) Machines shall be guarded as follows:
(1) Picker, opener, willow. Picker, opener, willow and similar equipment hopper feed shall be provided or the feed rolls shall be provided with a cover or guard arranged to protect the fingers of the operator while feeding material. The cylinder shall have a cover and be so interlocked that the cover does not open while the machine is in motion.
(2) Cangill boxes. A slotted cast iron guard through which the material passes shall be provided for the horizontal calendar roll at the delivery end of the machine.
(3) Shear-revolving knife. Shear shall have a cover or barrier bar arranged to protect the fingers of the operator from contact with the knife.
(4) Washer (laundry type), dry tumbler drum. A device shall be provided which acts to prevent the inside barrel from moving when the revolving drum door is open. If the revolving barrel is not enclosed by the machine itself no interlock is required but the barrel shall be smooth or so guarded as to prevent accidental contact with employes.
(5) Centrifugal extractor (whizzer). Each centrifugal extractor or whizzer shall be equipped with a metal cover provided with an interlocking device that prevents the cover from opening while the basket is in motion and the power operation of the basket while the cover is open. The device shall not prevent the movement of the basket by hand to insure an even loading. Each machine shall have an effective brake mechanically operated.
(6) Hussong machines. The superintendent shall cause all chains used in connection with Hussong machines to the inspected at least once a month and a report of such inspections shall be kept on file, accessible to inspectors of the Department at all times. The superintendent shall also be responsible for the constant supervision of the machines to insure that work is done under the safest possible conditions.
(7) Flat work ironer. Feed rolls shall be provided with a bar across the front so arranged that the striking of the bar by the hand of the operator stops the machine. Pressure rolls shall be covered or guarded to prevent a person from reaching into the rolls without removing the guard. This may be either a vertical guard on the sides or a complete cover depending upon which type of machine is used.
(8) Power guillotine cutter. A device shall be provided which, in order to operate the machine, requires the use of both hands in a position sufficiently distant from the point of operation of the machine so that the hands of an operator are not caught under the descending cutter.
(9) Slitter. A guard which completely encloses the cutting discs shall be provided to protect the fingers of the operator from accidental contact with the cutting edges when the machine is in operation.
(10) Sewing machines. Power-driven single needle sewing machines used for straight sewing without folders shall be provided with an approved needle guard so that the fingers of the operator are protected from accidentally slipping under the needle. The guard shall be of such form that the needle may be threaded conveniently without removing the guard.
(11) Looms. Pins or studs in eccentric motion of looms in or along passageways shall be guarded. An approved shuttle guard shall be provided.
