SAFETY CODE FOR THE PROTECTION OF INDUSTRIAL
WORKERS IN FOUNDRIES.

PRELIMINARY STATEMENT.
In January, 1920, the American Engineering Standards Committee
invited the American Foundrymen’s Association and the National
Founders’ Association to act as joint sponsors for a safety code for
the protection of industrial workers in foundries. These associations
accepted this sponsorship, and according to the rules of procedure
of the American Engineering Standards Committee appointed a
sectional committee to draft such a code. This committee consisted
of the following members:

At a meeting held February 9, 1921, and attended by a majority
of the sectional committee, a code was drafted which was later sub­
mitted to the entire sectional committee and to various technical
organizations for criticisms. At a meeting held February 14, 1922,
and attended by a majority of the sectional committee, these criti­
cisms were considered and some changes were made.
This code in its present form is the net result of this work and was
approved by The National Founders’ Association, The American

PROTECTION OP INDUSTRIAL WORKERS IN FOUNDRIES.

Foundrymen’s Association, Sectional Committee, by letter ballot,
American Engineering Standards Committee, June, 1922.
The membership of the two associations sponsoring this code is
composed of some three thousand of the leading foundries of the
United States.
INTRODUCTION.
SECTION 1. SCOPE.

This code deals with foundry conditions only, omitting such sub­
jects as building construction, exits, stairways, elevators, lighting,
sanitation, etc., as these subjects are covered by other codes.
SECTION 2. INTERPRETATIONS AND EXCEPTIONS.

The purpose of this code is to provide reasonable safety for life,
limb, and health. It shall be liberally construed to secure results, by
the enforcing officers of body, who shall have the authority in cases
of practical difficulty or unnecessary hardship, to grant exceptions
from the literal requirements of this code, as long as equivalent pro­
tection is thereby secured. When the safeguarding of particular
types of machines is covered by other approved codes, these codes
snail be given the preference. Where specific devices or methods are
mentioned in this code, other devices or methods which will
secure equally good results may be used, subject to the approval of
enforcing officer of body.
SECTION 3. APPLICATION OF REGULATIONS.

Regulations affecting industrial establishments generally in respect
to the safeguarding of transmission machinery, miscellaneous macninery, elevators, stairways, platforms, or relating to sanitary conve­
niences and first-aid equipments, not included in this code, shall
apply with equal force to foundries.
SECTION 4. SUSPENSION OF REGULATIONS.

This code may be modified or suspended in whole or in part by the
proper State authority in respect to existing foundries ii good and
sufficient reason therefor is submitted.
SECTION 5. MANDATORY AND ADVISORY REQUIREMENTS.

The word “ shall” where used, is to be understood to be mandatory,
and the word “ should” advisory.
SECTION 6. DEFINITIONS.

, Rale 60. Foundry.—A foundry shall mean a building where iron,
steel, tin, zinc, lead, aluminum or compositions containing any of the
baser metals are melted and poured into molds for the making of
castings, and shall include all molding, coremaking, melting, cleaning,
