Safety Data Sheets Under the New Globally Harmonized System
New chemicals are developed every day and for use in an ever-widening variety of applications. Providing accurate, clear and concise information to people who use, handle or store hazardous industrial chemicals is paramount.
On March 26, 2012, the Department of Labor adopted the United Nations' Globally Harmonized System of Classification and Labeling of Chemicals—otherwise known as GHS. This change ensures that OSHA's current Hazard Communication Standard (HCS) is aligned with internationally-developed guidelines for the categorization and labeling of hazardous substances.
Under the new GHS ruling, material safety data sheets (MSDS), will be referred to and called SDS (or Safety Data Sheets). The new standards affect any workplace that manufactures, uses, transports, or stores hazardous chemicals. One specific change in this ruling is to the ANSI Standardized MSDS format. The original 16-section MSDS format created by ANSI Z400.1 (2010 Rev.) will be replaced by the new SDS under the GHS system for classification for hazardous chemicals.
SDS's are the backbone of the Hazardous Communication System (HCS). They provide comprehensive and specific chemical information used not only by workplaces that manufacture, use, transport or store hazardous chemicals, but also by emergency responders, poison control centers and transporters of dangerous goods.
The standardized 16-section SDS mirrors the American National Standard for Hazardous Workplace Chemical's - Hazard Evaluation and Safety Data Sheet and Precautionary Labeling Preparation, ANSI Z400.1/Z129-1-2010. To be compliant, the SDS must have all 16 sections. OSHA however will not be enforcing sections 12-15 as they fall outside of their jurisdiction.
SDS (GHS Format) in Comparison to the ANSI Z400.1 MSDS 16-section Format.
New GHS SDS Format | ANSI Z400.1/Z129-2010 MSDS/SDS Format | |
|---|---|---|
1. | Identification of the Substance or Mixture and of the Supplier
| Product and Company Identification This section names the material and links the MSDS to the label and shipping documents. It also identifies the name of the manufacturer, importer or other responsible party, along with a mailing address and phone number for obtaining additional information. |
2. | Hazards Identification
| Hazard Identification Hazard identification is divided into the following four subsections:
The OSHA regulatory status subsection indicates if the material is hazardous or non-hazardous with respect to the OSHA Standard. Potential health effects and symptoms associated with exposure to the material are given in the potential effects subsection. Potential environmental effects and provides information related to effects associated with release of the material into the environment. |
3. | Composition/Information on Ingredients Substance
Mixture
| Composition/Information on Ingredients Identifies the components or by-products and impurities that contribute to the material's hazards.
|
4. | First Aid Measures
| First Aid Measures Divided into two subsections;
|
5. | Firefighting Measures
| Firefighting Measures Describes specific hazards arising from a fire and explosive properties of the material, along with appropriate extinguishing media for the fire, special protective equipment and firefighting precautions. |
6. | Accidental Release Measures
| Accidental Release Measures Information for responding to spills, leaks or releases in order to prevent or minimize the adverse health effects on persons, property and the environment. Also included may be information on personal protective equipment, containment equipment, clean-up equipment, clean-up techniques, environmental precautions and specific reporting requirements. |
7. | Handling and Storage
| Handling and Storage Provides guidance on safe handling and storage practices. Emphasis is on proper unique properties of the materials. |
8. | Exposure Controls/Personal Protection.
| Exposure Controls/Personal Protection Divided into three subsections: Subsection 1. The established exposure guidelines include, but are not limited to, OSHA's Permissible Exposure Limits (PELs) and American Conference of Governmental Industrial Hygienists (ACGIHs) Threshold Limit Values (TLVs), and Biological Exposure Indices (BEIs). Subsection 2. Gives consideration for personal protective equipment guidance eye/face protection, skin protection, respiratory protection and general hygiene. Subsection 3. Where engineering controls help minimize the hazards. |
9. | Physical and Chemical Properties
| Physical and Chemical Properties Identifies the physical and chemical properties of the material. If applicable and relevant, the following characteristics must be detailed: appearance, odor, odor threshold, physical state, pH, melting/freezing point, initial boiling point and boiling range, flash point, evaporation rate, flammability (solid, gas), upper/lower flammability or explosive limits, vapor pressure, vapor density, specific gravity or relative density, solubility, partial coefficient: n-octanol/water, auto-ignition temperature and decomposition temperature. If a characteristic is included, but not applicable or relevant, indicate so. |
10. | Stability and Reactivity
| Stability and Reactivity Describes the potential hazards associated with the stability and reactivity of the material under specified conditions. Chemical stability, conditions to avoid, incompatible materials, hazardous decomposition products and the possibility of hazardous reactions should be addressed. |
11. | Toxicological Information Concise but complete and comprehensible description of the various toxicological (health) effects and the available data used to identify those effects, including:
| Toxicological Information Provides toxicological information that can be used to assess human health hazards or potential health effects of the material and / or its components. Acute dose effects, repeated dose effects, irritation, corrosivity, skin and respiratory sensitization, carcinogenicity, neurological effects, genetic effects, reproductive effects, developmental effects and target organ effects data may be listed. |
12. | Ecological Information
| Ecological Information Information to assist in the evaluation of the environmental impact of the material and / or its components if released to the environment is provided in this section. Ecotoxicity, persistence / degradability, bioaccumulation / accumulation, mobility in environmental media and other adverse effects may be addressed. |
13. | Disposal Considerations
| Disposal Considerations Provides information that may be useful in the proper disposal, recycling or reclamation of the material and / or its container. |
14. | Transport Information
| Transport Information Basic classification information and special precautionary information to help a knowledgeable user prepare a material for shipment is given in this section. This section is not intended to contain every regulatory detail involving the transportation of a material. |
15. | Regulatory Information
| Regulatory Information Information on the regulatory status that is useful for compliance with health, safety and environmental regulations. Content and organization of this section depends on where the material is manufactured or used. It is not intended to be a comprehensive list of all of the regulations that may apply. U.S. Federal regulations / agencies shown may include the following: Clean Air Act (CAA), Clean Water Act (CWA), Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), Drug Enforcement Administration (DEA), Food and Drug Administration (FDA), OSHA, Safe Drinking Water Act (SDWA), Superfund Amendments and Reauthorization Act (SARA) Title III, Toxic Substances Control Act (TSCA) and United States Department of Agriculture (USDA). |
16. | Other Information Including Information on Preparation and Revision of the SDS | Other Information Any additional information that may be useful. It may include label text, hazard ratings, preparation and revision information or key/legend that explains the abbreviations used in the MSDS. |
Companies will have nearly two years to train their employees on the new GHS system. U.S. employees will need to be up to date in both the old and new regulations before December 2013, this will allow for a smoother transition to the new GHS SDS format. OSHA's final rule imposes the following deadlines on U.S. companies involved with chemicals:
- May 25, 2012: Transition period commences.
- December 1, 2013: Deadline to train employees on new labels.
- June 1, 2015: Deadline to comply with all amended provisions.
- June 1, 2016: Deadline to update alternative workplace labeling and hazard communication programs, and provide any additional employee training.
Other significant changes under the new rule include:
- Labels and SDSs will follow a more standardized format and contain a greater number of prescribed elements based on the chemical's classification.
- Formulators of mixtures will no longer be able to prepare an SDS by attaching component SDSs to a cover sheet; they must now provide a new SDS for the mixture itself.
Questions and Answers
Q. When do SDSs need to be updated?
A. On June 1, 2015 the Hazard Communication Standard (HCS) will require all modifications to SDSs to be uniform and in compliance with new format requirements.
Q. How is the Safety Data Sheet (SDS) changing under the revised Hazard Communication Standard?
A. The information required on the safety data sheet (SDS) will remain essentially the same as that in the current standard. The current Hazard Communication Standard (HCS) indicates what information has to be included on an SDS but does not specify a format for presentation or order of information. The revised HCS requires that the information on the SDS is presented using consistent headings in a specified sequence.
Q. Where can I get more information on the GHS and the impact on the HCS?
A. You can find information on the GHS and any impact it may have related to OSHA on the OSHA website: http://www.osha.gov/as/opa/facts-hcs-ghs.html
