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)
![Page 8: New Chemical Hazard Communication Standard Globally Harmonized System of Classification and Labeling of Chemicals, WAC 296-901-140.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649d845503460f94a6b440/html5/thumbnails/8.jpg)
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
![Page 10: New Chemical Hazard Communication Standard Globally Harmonized System of Classification and Labeling of Chemicals, WAC 296-901-140.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649d845503460f94a6b440/html5/thumbnails/10.jpg)
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.
![Page 11: New Chemical Hazard Communication Standard Globally Harmonized System of Classification and Labeling of Chemicals, WAC 296-901-140.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649d845503460f94a6b440/html5/thumbnails/11.jpg)
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– Upon completion of the transition period, the existing standard (296-800-170) will be repealed.
![Page 12: New Chemical Hazard Communication Standard Globally Harmonized System of Classification and Labeling of Chemicals, WAC 296-901-140.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649d845503460f94a6b440/html5/thumbnails/12.jpg)
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.”
![Page 13: New Chemical Hazard Communication Standard Globally Harmonized System of Classification and Labeling of Chemicals, WAC 296-901-140.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649d845503460f94a6b440/html5/thumbnails/13.jpg)
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.
![Page 14: New Chemical Hazard Communication Standard Globally Harmonized System of Classification and Labeling of Chemicals, WAC 296-901-140.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649d845503460f94a6b440/html5/thumbnails/14.jpg)
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

Hazard statements
![Page 34: New Chemical Hazard Communication Standard Globally Harmonized System of Classification and Labeling of Chemicals, WAC 296-901-140.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649d845503460f94a6b440/html5/thumbnails/34.jpg)
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
![Page 35: New Chemical Hazard Communication Standard Globally Harmonized System of Classification and Labeling of Chemicals, WAC 296-901-140.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649d845503460f94a6b440/html5/thumbnails/35.jpg)

"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
![Page 36: New Chemical Hazard Communication Standard Globally Harmonized System of Classification and Labeling of Chemicals, WAC 296-901-140.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649d845503460f94a6b440/html5/thumbnails/36.jpg)
There are 4 types of precautionary statements– Prevention– Response– Storage– Disposal
36
Precautionary statements
![Page 37: New Chemical Hazard Communication Standard Globally Harmonized System of Classification and Labeling of Chemicals, WAC 296-901-140.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649d845503460f94a6b440/html5/thumbnails/37.jpg)
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
![Page 38: New Chemical Hazard Communication Standard Globally Harmonized System of Classification and Labeling of Chemicals, WAC 296-901-140.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649d845503460f94a6b440/html5/thumbnails/38.jpg)
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
![Page 39: New Chemical Hazard Communication Standard Globally Harmonized System of Classification and Labeling of Chemicals, WAC 296-901-140.](https://reader036.fdocuments.us/reader036/viewer/2022062421/56649d845503460f94a6b440/html5/thumbnails/39.jpg)
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).

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
