OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules.

Dear Ms. Boisclair:

Thank you for your June 11, 2014, letter to the Occupational Safety and Health Administration's (OSHA) Directorate of Enforcement Programs. Your questions concern the labeling of secondary containers in laboratories under the Hazard Communication standard (HCS 2012), 29 CFR 1910.1200 and the Laboratory standard, 29 CFR 1910.1450. This letter constitutes OSHA’s interpretation only of the requirements herein, and may not be applicable to any questions not delineated within your original correspondence.

Safety Emporium has all kinds of lab equipment such as valves and faucets.

Background: HCS 2012 does not apply to laboratories that are covered under the Laboratory standard, 29 CFR 1910.1450. The HCS covers laboratories whose function is to produce commercial quantities of materials, and all laboratories connected with production processes, including quality control laboratories. The Laboratory standard, on the other hand, covers laboratories meeting the criteria of “laboratory use” and “laboratory scale” and excludes procedures that are part of a production process. 29 CFR 1910.1450(a)(1). The preamble to the Laboratory standard states most quality control laboratories are not expected to meet the qualification for coverage under the Laboratory Standard. Quality control laboratories are usually adjuncts of production operations... 55 Fed. Reg. 3300, 3312 (Jan. 31, 1990). Research and academic laboratories meeting the criteria of “laboratory use” and “laboratory scale” are covered by the Laboratory standard, not the HCS.

Other types of laboratories, such as quality control and production laboratories, that are not covered by the Laboratory standard are covered by the HCS. Under 29 CFR 1910.1200(b)(3), laboratories covered under the HCS must:

The series of OSHA publications on Laboratory Safety, including the information sheet you refer to in your letter, Laboratory Safety: Labeling and Transfer of Chemicals Quick Facts, are provided as guidance for employers and employees working in a laboratory-type setting in general. As we transition to full compliance with HCS 2012, the agency will be revising these and other publications to include the HCS 2012 requirements.

Your paraphrased questions and our responses are below.

Question: What is the expectation for labeling portable (secondary) containers in an academic or research laboratory?

Response: Academic and research laboratories that are covered under 1910.1450 are exempt from the HCS 2012. The Laboratory standard requires that labels on incoming containers of hazardous chemicals not be removed or defaced, 1910.1450(h)(1)(i), but does not have a specific labeling requirement for secondary containers of hazardous chemicals in a covered laboratory. The Laboratory standard allows laboratories flexibility in tailoring their written Chemical Hygiene Plan (CHP) and standard operating procedures to be protective of employees in laboratories (29 CFR 1910.1450(b)). In addition, 1910.1450(f)(4), Training, requires the employer to train employees regarding the physical and health hazards of chemicals in the work area, the measures employees can take to protect themselves from these hazards, and the employer’s CHP.

These solvent wash bottles from Safety Emporium are permanently labeled and ready for use.

OSHA encourages employers to consult non-mandatory Appendix A of the Laboratory standard, National Research Council Recommendations Concerning Chemical Hygiene in Laboratories, which contains numerous recommendations for labeling chemicals in laboratories. Employers may also wish to consult the most recent edition of the National Resource (sic); the correct word is "Research" Council's Prudent Practices in the Laboratory Handling and Management of Chemical Hazards for further recommendations on safe laboratory practices.1

Question 2: Will employers be required to re-label containers of hazardous materials previously purchased to comply with the HCS provisions?

Response: No, employers need not re-label containers of hazardous chemicals that were shipped prior to June 1, 2015. Manufacturers and importers are required to ship containers of hazardous chemicals with HCS 2012-complaint labels beginning June 1, 2015 (for distributors, the date is December 1, 2015). The employer should ensure that employees understand the differences between the HCS 1994-compliant labels and HCS 2012-compliant labels and that the lack of pictograms, signal words, etc., on HCS 1994-complaint labels does not mean the chemical(s) are less hazardous.

As you aware, the State of New York operates a public sector only occupational safety and health program under a plan approved by the U.S. Department of Labor. This program provides safety and health protections to state and local government employees within the state of New York. State plans are required to implement regulations that are “at least as effective” as the federal standards. If you would like further information regarding New York occupational safety and health requirements, you may contact the New York Department of Labor, Division of Safety and Health, at the following address:

Thank you for your interest in occupational safety and health. We hope you find this information helpful. OSHA's requirements are set by statute, standards, and regulations.  Our letters of interpretation do not create new or additional requirements but rather explain these requirements and how they apply to particular circumstances. This letter constitutes OSHA’s interpretation of the requirements discussed. From time to time, letters are affected when the
Agency updates a standard, a legal decision impacts a standard, or changes in technology affect the interpretation.
