Abstract
OSHA is correcting several inadvertent errors in its Hazard Communication Standard (HCS). Most errors relate to the HCS final rule published in the Federal Register on May 20, 2024. On October 9, 2024, the agency issued a corrections notification and technical amendment to correct errors in that final rule which the agency believed could lead to confusion during the classification process or errors on labels and Safety Data Sheets (SDSs) if not expeditiously corrected. Following publication of the October 9, 2024 corrections notification and technical amendment, OSHA continued its review of the regulatory text and identified additional minor and typographical errors in the regulatory text and appendices to the HCS. OSHA is issuing this correction document to address these additional minor errors. OSHA is also making one technical amendment to an appendix of the HCS unrelated to the May 20, 2024 final rule.

Hazard Communication Standard; Corrections
AGENCY: Occupational Safety and Health Administration (OSHA), Labor.
ACTION: Final rule; correction and technical amendment.
-----------------------------------------------------------------------
SUMMARY: OSHA is correcting several inadvertent errors in its Hazard
Communication Standard (HCS). Most errors relate to the HCS final rule
published in the Federal Register on May 20, 2024. On October 9, 2024,
the agency issued a corrections notification and technical amendment to
correct errors in that final rule which the agency believed could lead
to confusion during the classification process or errors on labels and
Safety Data Sheets (SDSs) if not expeditiously corrected. Following
publication of the October 9, 2024 corrections notification and
technical amendment, OSHA continued its review of the regulatory text
and identified additional minor and typographical errors in the
regulatory text and appendices to the HCS. OSHA is issuing this
correction document to address these additional minor errors. OSHA is
also making one technical amendment to an appendix of the HCS unrelated
to the May 20, 2024 final rule.
DATES: The corrections in this document are effective January 8, 2026.
The incorporation by reference of certain material listed in this rule
was approved by the Director of the Federal Register as of July 19,
2024.

SUPPLEMENTARY INFORMATION:
I. Overview
On May 20, 2024, OSHA published a final rule updating and revising
its Hazard Communication Standard (HCS) (89 FR 44144). The final rule
became effective on July 19, 2024. On October 9, 2024, the agency
issued a corrections notification and technical amendment to correct
errors in that final rule which the agency believed could lead to
confusion during the classification process or errors on labels and
Safety Data Sheets (SDSs) if not expeditiously corrected (89 FR 81829).
Following publication of the October 9, 2024 corrections notification
and technical amendment, OSHA continued its review of the final rule
and identified additional minor and typographical errors in the
regulatory text and appendices to the HCS. OSHA is issuing this
correction document to address these additional minor errors which
occur in paragraphs (c) and (d) of the regulatory text and in
Appendices A, B, C, D, and F. These corrections reflect the agency's
intent for the provisions of the final rule as explained in the
preamble to the final rule. Some of these corrections are explained in
the following discussion, and the table provided at the end of this
section summarizes all the corrections included in this document.
Four of the corrections are to paragraph (c) of the regulatory text
and one of the corrections is to paragraph (d) of the regulatory text.
These corrections add the heading ``Definitions'' to the beginning of
paragraph (c), add ``chemicals under pressure'' to the definition of
``Physical hazard,'' correct the formatting of the text of ``area'' in
the definition of ``Work area'' to match the formatting for other
terms, and correct the definition for ``Liquid'', which inadvertently
did not include the conversion of 14.69 PSI for all references to vapor
pressure. OSHA is also adding the heading ``Hazard Classification'' to
paragraph (d), which was inadvertently omitted from the 2024 final
rule.
The remainder of the errors corrected in this document are in the
Appendices. For instance, in Appendix A, OSHA is correcting the
reference within Figure A.1.1 which currently reads ``apply formula in
A.1.3.6.3'' to ``apply formula in A.1.3.6.4'' to cross reference the
correct paragraph. OSHA is also deleting elements that are in the GHS
which were inadvertently included in the final rule but are not
appropriate for OSHA's standard. These include statements such as
``which can be used by those authorities requiring more than one
designation for corrosivity'' and ``where sub-categorization is not
required by a competent authority or'' in paragraph A.2.2(a) and
references to tables that do not appear in the HCS. OSHA is correcting
figures A.6.1, A.7.1(a), A.7.1(b) and A.8.1, which were inadvertently
altered in the final rule, and is replacing these figures with the
versions of the figures included in the February 16, 2021 notice of
proposed rulemaking (86 FR 9576). The agency received no comments on
the proposed changes for Figure A.7.1(b) and intended to adopt them in
the final rule. OSHA did not propose changes for the other figures.
In Appendix B, OSHA is correcting several errors in spelling and
numbering in tables and text, as well as errors in the designations of
several footnotes in Appendix B. In addition, OSHA is updating Note 2
for both Table B.3.1 and B.3.2 to follow the same format, to add
``including their labeling elements'' to be consistent with the GHS,
and to correct cross references to other portions of Appendix B which
were inadvertently omitted or numbered incorrectly. OSHA is also
updating a footnote in each of Tables B.2.1, B.5.1, B.6.1 and B.7.1 by
adding ``chemicals under pressure.'' This will align these footnotes
with the text in Note 2 of Table B.3.2 regarding how chemicals under
pressure should be classified.
In Appendix C, OSHA is correcting minor formatting errors in
several places, such as italicizing, bolding, or
[[Page 563]]
un-bolding font and removing slashes that were inadvertently included.
Additionally, OSHA is adding ``Chemicals Under Pressure'' to Figure
C.1. This was inadvertently omitted from the list of hazard classes
associated with the Gas Cylinder hazard symbol. OSHA is also updating
the text of C.2.4.6 to use the updated version of the example
precautionary statement. OSHA is also making a number of corrections
related to Table C.4.16, including adding the precautionary statement
``In case of fire: Use . . . to extinguish'' and its associated
explanatory note to the ``Response'' column of Chemical Under Pressure
(Hazard Category 1 and 2). The latter change will accomplish OSHA's
stated intention to align with the GHS Rev. 8 (89 FR 44324). In Table
C.4.19, OSHA is removing the phrase ``Chemical manufacturer, importer,
or distributor to specify applicable ignition source(s),'' which it
inadvertently failed to delete in this table after updating the
precautionary statement to include all ignition sources (see 89 FR
44336). The agency is also adding the words ``and large quantities'' in
C.4.30, which were inadvertently omitted from the Hazard Category 4
Response precautionary statement.
In Appendix D, OSHA is correcting typographical errors in Section 2
and Section 7. Also in Appendix D, OSHA is correcting the Section 2(a)
cross-reference from (d)(1)(i) to (d)(1). This correction ensures that
Appendix D clearly conveys the requirements for providing the hazard
classification of a chemical in Section 2. As OSHA noted in the
preamble to the 2024 final rule, the agency intended to require hazards
associated with chemicals as shipped and hazards associated with a
change in the chemical's physical form to be presented in Section 2(a),
and hazards created by a chemical reaction to be presented in Section
2(c) (89 FR 44344). Finally, OSHA is removing the phrases ``methods
specified under'' and ``and then listed on the SDS'' from the note to
Table D.1 to align that language with the footnote in Appendix B as
OSHA stated it would in the HCS 2024 final rule (89 FR 44350).
OSHA is also making one technical amendment unrelated to the 2024
final rule. In Appendix F, the agency is revising the first sentence of
the section titled ``Responses Are in One Sex or Both Sexes'' to use
the term ``sex-specific tumors'' rather than ``gender-specific
tumors.'' A complete list of changes can be found below.
The following standards appear in the amendatory text of this
document and were previously approved for the locations in which they
appear: ADR 2019, ASTM D 4359-90, ASTM D 240-02, ISO 13943, NFPA 30B.

appeared in the 2021 NPRM.
II. Exemption From Notice-and-Comment Procedures
OSHA has determined that these corrections are not subject to the
procedures for public notice and comment specified in Section 4 of the
Administrative Procedures Act (5 U.S.C. 553) or Section 6(b) of the
Occupational Safety and Health Act of 1970 (29 U.S.C. 655(b)). This
rulemaking only corrects errors of a minor, mainly typographical nature
and makes technical amendments that do not affect or change any
existing rights or obligations, and no stakeholder is likely to object
to these changes. Therefore, OSHA has determined that there is good
cause that public notice and comment are unnecessary within the meaning
of 5 U.S.C. 553(b)(4)(B), 29 U.S.C. 655(b), and 29 CFR 1911.5. For the
same reasons, the Agency finds good cause under 5 U.S.C. 553(d)(3) to
make the amendment effective upon publication.

* * * * *
(c) Definitions. * * *
Liquid means a substance or mixture which at 122 [deg]F (50 [deg]C)
has a vapor pressure of not more than 43.51 PSI (300 kPa (3 bar)),
which is not completely gaseous at 68 [deg]F (20 [deg]C) and at a
standard pressure of 14.69 PSI (101.3 kPa), and which has a melting
point or initial melting point of 68 [deg]F (20 [deg]C) or less at a
standard pressure of 14.69 PSI (101.3 kPa). Either ASTM D 4359-90
(R2019) (incorporated by reference, see Sec. 1910.6); or the test for
determining fluidity (penetrometer test) prescribed in section 2.3.4 of
ADR 2019 (incorporated by reference, see Sec. 1910.6) can establish
whether a viscous substance or mixture is a liquid if a specific
melting point cannot be determined.
* * * * *
Physical hazard means a chemical that is classified as posing one
of the following hazardous effects: explosive, flammable (gases,
liquids, or solids); aerosols; chemical under pressure; oxidizer
(gases, liquids, or solids); self-reactive; pyrophoric (liquid or
solid); self-heating; organic peroxide; corrosive to metal; gas under
pressure; in contact with water emits flammable gas; or desensitized
explosive. The criteria for determining whether a chemical is
classified as a physical hazard are detailed in appendix B to this
section.
* * * * *
Work area means a room or defined space in a workplace where
hazardous chemicals are produced or used, and where employees are
present.

A.2.2 Classification Criteria for Substances
Substances shall be allocated to one of the following categories
within this hazard class:
(a) Category 1 (Skin Corrosion)
This category may be further divided into up to three sub-
categories (1A, 1B, and 1C).
[[Page 567]]
Corrosive substances should be classified in Category 1 where
data are not sufficient for sub-categorization.
When data are sufficient, substances may be classified in one of
the three sub-categories 1A, 1B, or 1C.
(b) Category 2 (Skin Irritation)
* * * * *
A.2.2.3.3.1 Where tests have been undertaken in accordance with
OECD Test Guidelines (TGs) 430, 431, or 435, a substance is
classified for skin corrosion in category 1 (and, where possible and
required into sub-categories 1A, 1B, or 1C).
* * * * *
A.2.2.3.4.1 Where a conclusion of corrosivity can be excluded
and where tests have been undertaken in accordance with OECD Test
Guideline 439, a substance is classified for skin irritation in
category 2.

Appendix F to Sec. 1910.1200--Guidance for Hazard Classifications Re:
Carcinogenicity (Non-Mandatory)
* * * * *
Responses Are in One Sex or Both Sexes
Any case of sex-specific tumors should be evaluated in light of
the total tumorigenic response to the substance observed at other
sites (multi-site responses or incidence above background) in
determining the carcinogenic potential of the substance.
If tumors are seen only in one sex of an animal species, the
mode of action should be carefully evaluated to see if the response
is consistent with the postulated mode of action. Effects seen only
in one sex in a test species may be less convincing than effects
seen in both sexes, unless there is a clear patho-physiological
difference consistent with the mode of action to explain the single
sex response.
