2012 Chemical Hazard Communication Standard

New Chemical Hazard Communication StandardGlobally Harmonized System of Classification and Labeling of Chemicals, WAC 296-901-1401Overview of GHS and changes to the standard2What is the GHS?Harmonized criteria for classifying substances and mixtures according to their health, environmental and physical hazards.Harmonized hazard communication system including requirements for labeling and safety data sheets (SDS).Target audience - workers, employers, consumers, transport workers, emergency responders.

The current edition is the 4th; revision continue on a 2-year cycle. So far, most have been text clarifications. 4

Agencies Involved with the GHS

FederalWashington StateDOTWSDOTOSHAL&I / DOSHEPADOE & WSDACPSC The DOT was actually the first American agency to implement GHS and OSHAs adoption brings the regulations between those two agencies into greater harmony. The EPA is expected to follow closely on the heels of OSHAs adoption with revisions to its own standards to bring them into alignment with GHS.


Dark green: Countries/regions that have already implemented GHS. Light green: Countries/regions where GHS is voluntary. Yellow: Countries/regions that are in the process of implementing GHS. Blue: Countries/regions where GHS is not implemented or not available.To date, over 65 countries have adopted GHS or are in the process of adopting GHS.

6OSHAs HazCom 2012 StandardPublished March 26, 2012Conforms to the GHS, Rev. 3Changes to:Hazard classificationLabel contentSafety Data Sheet content (mandatory 16 section SDS, % required)

On March 26, 2012, OSHA revised the Hazard Communication Standard to align with the GHS.

OSHA calls the new version HazCom 2012.7Stay 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.

Effective April 15, 2013

On March 26, 2012, OSHA revised the Hazard Communication Standard to align with the GHS.

OSHA calls the new version HazCom 2012.

9Substantially identical to OSHAs standardPhase-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.10Substantially identical to OSHAs standardPhase-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.

11ExemptionsAll 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.

Nuisance particulates where the chemical manufacturer or importer can establish that they do not pose any physical or health hazard covered under this section;

This is rather complicated12Major Changes Labels & SDSNo 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.13Major Changes Hazard determinationNow titled hazard classificationDetailed data-based criteriaHealth hazard criteria in mandatory Appendix A and non-mandatory Appendix FPhysical hazard criteria in mandatory Appendix BSpecified; no longer performance-based

14Classification of chemical hazardsHazard 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. Appendix A discusses health hazards, and Appendix B discusses physical hazards.

Hazard Class: Describes the nature of the physical or health hazards For example, "Gases under Pressure" is an example of a class in the physical hazards group.

Hazard Category: Describes the degree of hazard within a class. The specific criteria varies with the type of hazard.

15Hazard ClassHazard Category (health hazard criteria, Appendix A)Acute toxicity1234Skin corrosion/irritation1A1B1C2Serious eye damage/irritation12A2BRespiratory or skin sensitizers 1A1BGerm cell mutagenicity 1A1B2Carcinogenicity 1A1B2Reproductive toxicity 1A1B2lactationSpecific target organ toxicity - single exposure 123Specific target organ toxicity - repeated exposure12Aspiration1These are the hazard classes and categories for health hazards, from Appendix A.

Example: Flammable liquidsCategory 1: Extremely flammable liquid and vapourCategory 2: Highly flammable liquid and vapourCategory 3: Flammable liquid and vapourCategory 4: Combustible liquid323232The 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.

33Hazard statementsMultiple hazardsThe 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 toxicityIf corrosive, no exclamation point for eye/skin irritationIf 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 statements35PDC 408 GHS 2012There are 4 types of precautionary statementsPreventionResponseStorageDisposal

36Precautionary statementsPrecautionary statementsMay 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.37Supplementary hazard informationOnly 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.38Label arrangementLabel 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 b
