OSHA’s Hazard Communication Standard Move to Align with Globally Harmonized System of Classification and Labeling of Chemicals (GHS)
Under its Hazard Communication Standard (HCS) (29 CFR 1910.1200), the Occupational Safety and Health Administration (OSHA) requires Safety Data Sheets (SDSs) for all hazardous chemicals. In March 2012, OSHA published a final rule to align its HCS regulations with the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). The primary goal of GHS is improved protection of human health and the environment by providing chemical users and handlers with enhanced and consistent information on chemical hazards. The GHS is based on major existing systems for industrial chemicals, pesticides, consumer chemicals, and chemicals in transport, but implementation of the GHS would require some changes in all existing systems in order to achieve harmonization.
However, it is important for growers who use federally regulated pesticides to note that the Environment Protection Agency (EPA) has not yet moved to amend its pesticide labeling regulations under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to align with the GHS. The differences between EPA’s current requirements and the GHS are related to classification criteria, hazard statements, pictograms, and signal words. For example, FIFRA pesticide product labels may contain the following signal words: of “Danger Poison with the skull and crossbones graphic,” “Warning,” or “Caution” depending on the toxicity level of the product, and “Danger” for a product that may be a potential skin or eye irritant. The GHS uses only two signal words, “Danger” and “Warning.” To illustrate, the label of a chemical that has an oral LD50 of 550 mg/kg bears the signal word “Caution” under current FIFRA labeling practices but would require the signal word “Warning” under the GHS.
For pesticide products, FIFRA labels approved by EPA pre-empt OSHA’s label requirements, but not the requirements for SDS and worker training (except for certified applicators and agricultural workers for whom EPA has training requirements). EPA realizes that this may require users of the SDS that are prepared for pesticide products to become familiar with two different systems, at least until the agencies’ requirements are harmonized. As a result, EPA issued guidance in the April 20, 2012 Federal Register to manufactures so that when changes are made to the SDS to meet the OSHA requirements, the new SDS format will also be in compliance with the pesticide regulations under FIFRA. This guidance is commonly referred to as Pesticide Registration (PR) Notice 2012-1.
Why the switch from MSDS to SDS?
For many years under the HCS, this last responsibility was met by maintaining a copy of the Material Safety Data Sheet (MSDS) for each product that was considered a hazardous chemical, some of which are pesticides. Under the Haz Com 2012, the MSDS will be replaced with a Safety Data Sheet (SDS). Before the Haz Com 2012, there were several acceptable MSDS formats. OSHA’s adoption of Global Harmonization Standards (GHS) requires the use of a single format with 16 sections that appear in a specific order. Although this change seems to have become a cause for concern, in all practical reality, there is very little difference between the two documents.
Will the change require that both and MSDS and an SDS be kept for the same product?
For compliance with the new OSHA Haz Com 2012 regulatory requirements, maintaining both an MSDS and a SDS for the same chemical is not necessary. In the next few years as the SDS becomes available for individual products, they will replace the existing MSDSs. Although there is no requirement to keep the older MSDS once it is replaced with an SDS, a good management practice would be to keep an electronic copy on file, especially if existing stocks of the chemical were purchased under the older MSDS.
However, when the chemical in question is a pesticide and the content of the MSDS and the SDS differs, a copy of both documents must be maintained to ensure compliance with OSHA HazCom 2012 and FIFRA which regulates pesticide products.
