Ohio Administrative Code › Title 4123:1 - Division of Safety and Hygiene › Chapter 4123:1-7 - Metal Casting › Section 4123:1-7-01 - Scope and definitions

Current through all regulations passed and filed through July 1, 2024
(A) Scope.
The purpose of this chapter of the Administrative Code is to
				provide reasonable safety for life, limb and health of employees. In cases of
				practical difficulty or unnecessary hardship, the Ohio bureau of workers'
				compensation may grant exceptions from the literal provisions of the rules of
				this chapter or permit the use of other devices or methods when, in the opinion
				of the bureau, equivalent protection is thereby secured.
The specific requirements of this chapter supplement those of
				Chapter 4123:1-5 of the Administrative Code, and are minimum
				requirements of an employer for the protection of such employer's employees and
				no others and apply to the manufacture of castings containing iron, steel,
				brass, copper, tin, zinc, lead, aluminum, or any of the baser metals, but do
				not apply to steel making or any processes used in conjunction with steel
				manufacturing and fabricating.
Installations or constructions built or contracted for prior to
				the effective date of any requirement shall be deemed to comply with the
				provisions of these requirements if such installations or constructions comply
				either with the provisions of these requirements or with the provisions of any
				applicable specific requirement which was in effect at the time contracted for
				or built.
(B) Definitions.
(1) "Core" means a preformed sand aggregate
			 inserted into a mold to shape the interior of a casting.
(2) "Core box" means a wood, metal or plastic
			 structure used to shape sand into a core.
(3) "Crucible" means a ceramic pot or
			 receptacle used in melting molten metal, transporting it or both.
(4) "Cupola" means a cylindrical furnace

			 forcing air under pressure through openings near its base.
(5) "Factor of safety" means the ratio
			 between the ultimate breaking stress and the working stress of the material,
			 structure, or device. For example, the term "factor of safety of four" means
			 the material, structure or device shall be constructed of such strength that
			 the maximum load will be one-fourth the designed ultimate breaking load. Where
			 other factors of safety appear, they shall apply in the same manner. The
			 standards of the "American Society for Testing Materials" shall be used in
			 determining the strength of material except as otherwise provided herein.
(6) "Flask" means the frame which
			 holds the sand or other substance forming the mold.
(7) "Gallery" means a corridorlike platform,
			 passage or walkway, especially one projecting from a wall and open at the outer
			 edge.
(8) "Guard" means the

(9) "Guarded"
			 means that the object is covered, fenced, railed, enclosed, or otherwise
			 shielded from accidental contact.
(10) "Ladle" means a metal receptacle
			 frequently lined with refractories used for transporting and pouring molten
			 metal.
(11) "Mold" means the form
			 into which molten metal is poured to produce a casting.
(12) "Operator" means any employee assigned
			 or authorized to work at the specific equipment.
(13) "Passageway" means a well defined aisle,
			 gangway, walkway, etc., used for movement of employees and equipment, but does
			 not include the space between molds unless regularly used for such movement.
(14) "Pig hole" means the opening
			 into which the excess molten metal is poured.
(15) "Pig mold" means a mold used to hold
			 excess molten metal.
(16) "Pouring
			 floor or area" means the floor or area where molten metal is poured.
(17) "Shall" is to be construed as mandatory.
(18) "Substantial" means
			 construction of such strength, of such materials, and of such workmanship that
			 the object will withstand the wear, usage or shock for which it is designed.
(19) "Trunnion" means the
			 cylindrical metal support attached to the side of a ladle or flask.
(20) "Tumbling mill" means a rotating barrel
			 in which castings are cleaned.
