OSHA Instruction STD 1.12-27 June 30, 1981 Office of Compliance Programming
Subject: Applicable Standards As They Pertain to Iron Workers and Mechanical Power Presses
A. Purpose. This instruction provides guidelines to aid in the recognition of the difference between iron workers and similarly configured mechanical power presses as they are used in industry. Proper identification will permit the correct application of standards.
B. Scope. This instruction applies OSHA wide.
C. Reference. OSHA Instruction STD 1-12.21, February 2, 1978.
D. Action. OSHA Regional Administrators/Area Directors shall use the guidelines set forth in F of this instruction for the enforcement of 29 CFR 1910.212 and 29 CFR 1910.217, as applicable.
E. Federal Program Change. This instruction describes a Federal program change which affects State programs. Each Regional Administrator shall:
- 1. Ensure that this change is forwarded to each State designee.
- 2. Explain the technical content of the change to the State
designee as requested.
- 3. Ensure that State designees are asked to acknowledge receipt of
this Federal program change in writing, within 30 days of notification, to
the Regional Administrator. The acknowledgment should include a description
either of the State's plan to implement the change or of the reasons why the
change should not apply to that State.
- 4. Review policies, instructions and guidelines issued by the State
to determine that this change has been communicated to State program
personnel. Routine monitoring activities (accompanied inspections
OSHA Instruction STD 1-12.27 June 30, 1981 Office of Compliance Programming
- case file reviews) shall also be used to determine if this
change has been implemented in actual performance.
F. Guidelines. For compliance purposes, OSHA field staff will assure that the requirements of 29 CFR 1910.212 and 217, with applicable sections, are applied as interpreted by this instruction.
- 1. This instruction applies to those combination, multipurpose
powered machines that punch, shear, notch, cope, and form metals or other
materials, commonly referred to as iron workers, and also applies to certain
single-purpose powered machines, noted below.
- a. Specific machines to which 29 CFR 1910.212 shall apply
include, but are not limited to, the following:
- (1) Single-end punches (2) Double-end punches (3) Structural
shearing machines (4) Notching machines (5) Coping machines (6) Beam punches
(7) Detail punches (8) Spacing punches (9) Combinations of (1) through
- b. Machines similar in construction and function to mechanical
power presses, but which are identified by the respective machine
manufacturers as iron workers, are regulated under 29 CFR
- c. Machines whose most distinguishing feature is the multiple
work stations at which various operations may be performed singly or simul
taneously, including, but not limited to, punching, shearing, notching,
coping, and forming, shall be evaluated as an iron worker, and are regulated
under 29 CFR 1910.212.
- OSHA Instruction STD 1-12.17 June 30, 1981 Office of
- 2. Mechanically powered machines that shear, punch, form, or
assemble metal or other material by means of tools or dies attached to
slides, and identified by their respective manufacturers as mechanical power
presses, are regulated under 29 CFR 1910.217.
G. Background. Compliance officers have frequently confused the applicability of standards as they pertain to iron workers and certain configurations of mechanical power presses. In addition, field personnel have incorrectly attempted to enforce provisions of 29 CFR 1910.217 with regard to iron workers. 29 CFR 1910.212 is the appropriate standard to apply to ironworker machines.
- 1. ANSI B11.5-1975, Safety Requirements for the Construction, Care,
and Use of Iron Workers, deals specifically with ironworkers. Although this
standard has not been adopted by OSHA under section 6(b), it provides useful
guidance in evaluating and correcting ironworker hazards.
- 2. ANSI B11.5-1975 should be consulted when considering a citation
under 1910.212 or when attempting to enforce a citation issued under that
standard for exposure to a hazard on an ironworker machine.
