(a)
Inspectors.
Ladles, shanks, tongs, slings, yokes, skimmers,
					 and slag hoes used in the pouring of molten metal shall, prior to their use, be
					 inspected daily as to their safety by the men preparing and using them. A
					 regular inspection as to their safety shall be made once a month by a man
					 designated for that purpose. A monthly inspection shall also be made of the
					 chains and cables on counterweights used in connection with drying ovens, and a
					 record kept of such inspections.
(b)
Fireways.
Fireways
					 connected with drying ovens, when built in the floor, shall at all times be
					 protected by either a substantial protecting cover or a standard railing as
					 defined in Subchapter G (relating to railing, toeboards, open-sided floors,
					 platforms and runways).
(c)
Trapdoors.
Trapdoors shall be guarded when open, either by
					 standard railings as defined in Subchapter G or by watchman. All pits shall be
					 covered or railed when not in use and sufficiently guarded at other
					 times.
(d)
Passageways and
					 stairs.
Passageways, stairways, inclines, runways, charging decks and
					 platforms shall be properly lighted and have tread surfaces so constructed and
					 maintained that persons walking on them do not slip or trip, and safeguarded
					 with standard railings as defined in Subchapter G.
(e)
Worm gears.
All ladles
					 pouring from the lip of 2,000 or more pounds capacity shall be equipped with a
					 worm geared device for tilting the device. Ladles not so equipped shall be
					 changed to conform with this requirement. All crane truck and trolley pouring
					 ladles shall be so constructed that the center of gravity is below the bail,
					 unless ladles are equipped with a geared device and a clip to prevent
					 overturning.
(f)
Trunions.
Trunions on flasks shall sustain the loads they are required to
					 handle. Trunions constructed after 1927 shall be carefully designed to carry
					 the load they are to handle and constructed with a factor of safety of at least
					 ten including bolts when they are used. The diameter of the button shall be
					 equal to the diameter of the groove plus 1 1/2 times the diameter of the sling
					 used to handle the flask. Inside corners shall be well filleted, and, in order
					 to prevent the sling slipping off or riding the button, the radius of the
					 corner between groove and button shall be approximately equal to the radius of
					 the sling used with the remainder of the inside edge of the button straight.
					 All trunions constructed after October 1, 1915, shall bear the date of their
					 construction.
(g)
Explosives.
The use of high explosives on the foundry premises
					 for the breaking of castings is prohibited unless effective protection is
					 provided.
(h)
Drop.
The breaking of castings by the use of a drop inside the foundry
					 during working hours is prohibited.
(i)
Drop outside the foundry.
When a drop is used for the breaking of castings or scrap outside of
					 the foundry, a permanent shield of heavy planking or other effective protection
					 shall be provided.
(j)
Safety devices.
Each employe shall use safety devices
					 furnished for his protection by the employer, when there is a hazard connected
					 with his employment.
(k)
Legs and feet.
Persons employed in iron or steel foundries who
					 remove or handle pots or ladles containing molten metal from furnaces shall be
					 provided with protection for the legs and feet and worn at all times while
					 engaged in such work.
(l)
Head and eye.
Each employe whose head, eyes or neck is subject
					 to injury from flying particles, heat or glare, or from the handling of molten
					 metal shall be provided with and use protection as specified in Chapter 39,
					 Subchapter C (relating to head and eye protection).
(m)
Tumbler barrels.
Tumbling barrels shall be guarded as follows:
(1) All drive belts, gears and shafting shall
					 be guarded as required by Chapter 29 (relating to mechanical
					 apparatus-miscellaneous) on all types of tumbling barrels.
(2) Horizontal revolving and reciprocating
					 tumbling barrels operated singly or in a single line shall be guarded as
					 follows:
(i) Loading and unloading sides shall
					 be guarded either by a guard 6 feet high with not more than 1/2 inch mesh, such
					 guard rising vertically or inclined, or a hood over the barrel supported by
					 counterweights. In either method it shall be interlocked with a belt
					 shifter.
(ii) When a clearance of
					 15 inches on all sides of the barrel is obtained and the barrel revolved
					 upwards from the loading and unloading sides with all projections pointed
					 downward, no enclosure is required.
(3) When barrels operate back to back there
					 shall be a platform over the shaft.
