Dear Mr. Miller:

Thank you for your letter of December 9, 1993 to Joseph Dear, Assistant Secretary of Labor, regarding the Occupational Safety and Health Administration's (OSHA) Hazard Communication Standard (HCS) Material Safety Data Sheet (MSDS) provisions. In that letter you indicated that you are developing a compendium of MDSDs that will be distributed to all practicing dentists and that, based on a survey of manufacturers, there is a high likelihood that all manufacturers of dental products would submit MSDSs for inclusion. You inquired whether submission of MSDSs for publication in the compendium would fulfill a manufacturer's obligations under the HCS.

Section (g)(6) of the HCS is most relevant to your inquiry and it states that: "Chemical manufacturers or importers shall ensure that distributors and employers are provided and appropriate MSDS with their initial shipment, and with the first shipment after a material safety data sheet is updated." OSHA included these paragraph (g) requirements in the HCS to ensure that employers obtain the information necessary to inform their employees of the potential health hazards associated with using the product before those employees were exposed to the hazards.

The HCS allows flexibility for chemical manufacturers to use any method to provide MSDSs that meets the requirement of the standard. The MSDS book you describe may meet these requirements, as long as employers are provided the necessary MSDSs.

We do have some concerns about your proposal. According to the HCS the manufacturer and importer have the obligation to ensure that the MSDS are provided to the employer. The procedure that you describe appears to shift responsibility from the chemical manufacturer or importer who must provide an MSDS to the dental employer who would then have to ensure that the MSDS had been included in the book. Under the system that you propose it is likely that some dentists will not receive a new or revised MSDS at or before the time of product shipment, even if the compendium is updated quarterly. Such situation would not be in compliance with the HCS. You would have to ensure that through some mechanism MSDSs are provided to employers in a timely fashion, i.e., with their initial shipment, and with the first shipment after a material safety data sheet is updated.

You raised the following question in your letter: "even if we guarantee every dentist will receive an MSDS book with updates, they (chemical manufacturers) will still be required to send individual MSDS to dentists if requested." This is an issue between the chemical manufacturer and the MSDS requester and as long as the HCS MSDS requirements are met, it does not involve OSHA.

We hope that this information will be of use to you.
