OSHA’s “HazCom 2012” Standard

Published March 26, 2012

Conforms to the GHS, Rev. 3

Changes to:– Hazard classification

– Label content

– Safety Data Sheet content (mandatory 16 section SDS, % required)

Stay tuned . . .

The GHS is updated on a two year cycle.

Recent updates have mostly been text clarifications.

Future updates of the Chemical Haz Com standard may be necessary.

WISHA’s new GHS-based

Hazard Communication Standard

Effective April 15, 2013

Substantially identical to OSHA’s standard

Phase-in schedule:– During the transition period, there is the option to comply with

the applicable requirements in the existing rules, or the requirements in the new rule, or both.

– June 1, 2014: ERs train EEs on Safety Data Sheet (SDS) format and new label elements.

– June 1, 2015: Manufacturers & importers comply with new SDS and label requirements.

– Dec. 1, 2015: Distributors not to ship unless container has GHS label.

Substantially identical to OSHA’s standard

Phase-in schedule, cont.:

– June 1, 2016: ERs update labels, EE hazard training, and written Haz Com programs.

– Upon completion of the transition period, the existing standard (296-800-170) will be repealed.

Exemptions

All the current exemptions from the rule, and exemptions from labeling, still apply.

One new exemption from the rule:– “Nuisance particulates where the chemical

manufacturer or importer can establish that they do not pose any physical or health hazard covered under this section.”

Major Changes

Labels & SDS

– No longer performance-based.

– Each hazard class and category has specified hazard statement(s), signal word, pictogram(s), and precautionary statement(s) in mandatory Appendix C. Those elements must appear on the label and SDS.

Major Changes

Hazard determination

– Now titled “hazard classification”

– Detailed data-based criteria

• Health hazard criteria in mandatory Appendix A and non-mandatory Appendix F

• Physical hazard criteria in mandatory Appendix B

– Specified; no longer performance-based

Classification of chemical hazards

Hazard class: the nature of the physical or health hazards, e.g., flammable solid, carcinogen, oral acute toxicity.

Hazard category: division by degree or type of hazard within each hazard class.

Hazard Class Hazard Category (health hazard criteria, Appendix A)

Acute toxicity 1 2 3 4

Skin corrosion/irritation 1A 1B 1C 2

Serious eye damage/irritation 1 2A 2B

Chronic hazards to the aquatic environment – Categories 1 and 2 (Categories 3 and 4 use no symbol or signal word)

*Part of GHS, but not required by WISHA or OSHA standards.

Hazard statements

Hazard statement is specified for each level of hazard (category) within each hazard class (See Appendix C)

– Example: Flammable liquids Category 1: Extremely flammable liquid and vapour Category 2: Highly flammable liquid and vapour Category 3: Flammable liquid and vapour Category 4: Combustible liquid

32

The text of all applicable hazard statements shall appear on the label.

Hazard statements may be combined where appropriate to reduce the information on the label and improve readability, as long as all of the hazards are conveyed as required.

33

Hazard statements

Multiple hazards

The pictogram and signal word used must reflect the most severe hazard category; and all relevant hazard statements must be used.

– If skull and crossbones, no exclamation point for acute toxicity

– If corrosive, no exclamation point for eye/skin irritation

– If health hazard for respiratory sensitization, no exclamation point for skin sensitization or eye/skin irritation

35

"Precautionary statement" means a phrase that describes recommended measures that should be taken to minimize or prevent adverse effects resulting from exposure to a hazardous chemical, or improper storage or handling.

Precautionary statements

There are 4 types of precautionary statements– Prevention– Response– Storage– Disposal

36

Precautionary statements

Precautionary statements May be combined or consolidated to save label space

and improve readability.

Where a chemical has multiple hazards and the precautionary statements are similar, the most stringent shall be included on the label.

An order of precedence may be imposed.

If the chemical manufacturer, importer, or responsible party can demonstrate that a precautionary statement is inappropriate to a specific substance, it may be omitted from the label. 37

Supplementary hazard information

Only allowed if it provides further detail and does not contradict or cast doubt on the validity of the standardized hazard information.

Placement shall not impede identification of information required by the Standard.

38

Label arrangement Label elements must be located together on the label,

tag or mark. Must not conflict with DOT regulations. Pictograms must have red border. Red frame must be wide enough to be clearly visible. Blank red diamonds are not permitted. Where a DOT label appears on a shipped container,

the same OSHA pictogram shall not appear. Labels must be in English (other languages also

permitted).

1. Product identifier 4. Hazard statement(s)2. Signal word 5. Precautionary statement(s)3. Pictogram(s) 6. Contact info for responsible

party

Potential for confusion

In NFPA 704 and HMIS, “4” = severe hazard In GHS, “4” = low hazard

GHS Category Hazard

1 highest

2 high

3 medium

4 low

HMIS/NFPAIndex Hazard

1 slight

2moderate

3serious

4severe

From the preamble to OSHA’s new standard:“Neither the proposal nor final rule prohibits the use of NFPA or HMIS rating systems.” – Federal Register, 77(58), Monday, March 26, 2012, p. 17758

May confuse employers who need to look up hazard categories.

Most employees won’t notice unless it’s covered in their training, because hazard categories don’t appear on labels or SDSs (only used to determine required label info)

Potential for confusion

Potential for confusion

MATERIAL SAFETY DATA SHEETSSAFETY DATA SHEETS

16-section format now required, similar to the current ANSI format.

Order of the sections is specified.

Specific required information for each section is in mandatory Appendix D.

Environmental provisions are included to be GHS-compliant; DOSH will not enforce (sections 12-15).

SAFETY DATA SHEETS

Safety Data Sheets

Safety Data Sheets Must be in English (additional languages OK)

If there’s no relevant information for a section, it must be marked to indicate no data

Preparer must assure information accurately reflects the scientific evidence used in making the hazard classification

Preparer must update within 3 months of significant new information. If not currently produced, then before shipped again or introduced into the workplace.

SDS distribution

Provide with initial shipment, and with first shipment after update.

Either before or with the shipment, on request.

Retail and wholesale distributors shall post a sign or inform employers that SDSs are available.

New SDS elements

Standardized pictograms, hazard statements, signal words, and precautionary statements

Exact percentages of ingredients are required in most cases; some may still give ranges:– When there is a trade secret claim.

– When a product varies batch-to-batch.

– For a group of substantially similar mixtures with similar chemical composition.
