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
specification are deemed to comply

structure, or device. For example, the term "factor of safety of four" means
the material, structure, or device
shall be
is
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
will
apply in the same manner. The standards of the "American Society for Testing
Materials" shall
will be used in determining the strength of material
except as otherwise provided herein.

(13) "Passageway" means a well-defined

for such movement.
(14) "Pig hole"

(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

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
