OSHA Issues Proposed Update to Hazard Communication Standard
Publications
February 10, 2021
On February 5, 2021, the U.S. Occupational Safety and Health Administration (OSHA) issued a proposed rule updating its Hazard Communication (“Haz Com”) Standard to align its rules with those in the seventh version of the United Nation’s Globally Harmonized System of Classification and Labeling of Chemicals (GHS), published in 2017. OSHA’s proposed regulatory update is being issued as the United States’ major international trading partners, including Canada, Australia, New Zealand, and those in Europe, similarly prepare to align their own hazard communications rules with the seventh version of the GHS.
Originally established in 1983, OSHA’s Haz Com Standard provides a systematized approach to communicating workplace hazards associated with exposure to hazardous chemicals. Under the Haz Com Standard, chemical manufacturers and/or importers are required to classify the hazards of chemicals which they produce or import into the United States, and all employers are required to provide information to their employees about the hazardous chemicals to which they are exposed, by means of a hazard communication program, labels and other forms of warning, safety data sheets, and information and training. At an international level, the GHS provides a universally harmonized approach to classifying chemicals and communicating hazard information. Core tenants of the GHS include universal standards for hazard testing criteria, warning pictograms, and safety data sheets for hazardous chemicals.
In a pre-published version of the proposed rule, OSHA’s proposed modifications to the Haz Com Standard include codifying enforcement policies currently in OSHA’s compliance directive, clarifying requirements related to the transport of hazardous chemicals, adding alternative labeling provisions for small containers and adopting new requirements related to preparation of Safety Data Sheets. Key modifications included in the proposed rule, include:
- New flexibility for labeling bulk shipments of hazardous chemicals, including allowing labels to be placed on the immediate container or transmitted with shipping papers, bills of lading, or by other technological or electronic means that are immediately available to workers in printed form on the receiving end of the shipment;
- New alternative labeling options where a manufacturer or importer can demonstrate that it is not feasible to use traditional pull-out labels, fold-back labels, or tags containing the full label information normally required under the Haz Com Standard, including specific alternative requirements for containers less than or equal to 100ml capacity and for containers less than or equal to 3ml capacity; and
- New requirements to update the labels on individual containers that have been released for shipment but are awaiting future distribution where the manufacturer, importer or distributer becomes aware of new significant information regarding the hazards of the chemical.
OSHA last updated its Haz Com Standard in 2012, to align the standard with the then recently published third version of GHS. In its newly proposed rule, OSHA clarifies that it is “not proposing to change the fundamental structure” of its Haz Com Standard, but instead seeking to “address specific issues that have arisen since the 2012 rulemaking” and to provide better alignment with international trading partners. According to OSHA, its proposed modifications to the Haz Com Standard “will increase worker protections, and reduce the incidence of chemical-related occupational illnesses and injuries by further improving the information on the labels and Safety Data Sheets for hazardous chemicals.”
OSHA is currently accepting comments on its proposed rule until April 19, 2021. Comments may be submitted electronically to Docket No. OSHA-2019-0001at http://www.regulations.gov, which is the Federal e-Rulemaking Portal.
