Current through Register Vol. 54, No. 28, July 13, 2024
(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.
