Omitting inapplicable sections from material safety data sheets

Summary State plan officials asked whether a material safety data sheet must display every possible information field, even when a field is inapplicable. OSHA said a preparer may omit an entire inapplicable section, including on computer-generated sheets, but any field retained on the form must be filled or marked with an explanatory notation. The guidance matters to employers and chemical suppliers designing data sheets.

MEMORANDUM FOR: NANCY BURKHEIMER, Deputy Commissioner of Maryland Division of Labor and Industry

FROM: BRUCE HILLENBRAND, Director Federal-State Operations

Subject: MSDS Question


As you will recall, at the Chapel Hill meeting the State of Washington inquired about the intent of the attached October 9, 1987, memorandum form Thomas Shepich, Director of Compliance Programs, on Material Safety Data Sheets (MSDS) required under the Hazard Communication standard. The memorandum addressed whether a MSDS format must include blocks or spaces for information that is not applicable or available for the substance involved. This question had been raised particularly by manufacturers that use computer-generated MSDSs. It is customary to exclude fields on such MSDSs when there is no information.

The States thought that it was preferable to provide a "not applicable" notation in such blocks rather than to omit them form the form. In response to our request for clarification, the following information has been provided by Mr. Shepich:

Since the standard is performance-oriented and not MSDS format is specified, employers are free to develop MSDSs that are designed for a specific chemical. For example, if an employer develops an MSDS for a chemical which is not a carcinogen, a space addressing carcinogenicity does not have to be provided on the form. This policy applies to any type of MSDS including computer-generated ones.

Of course, if a format is used which has a space addressing carcinogenicity or any other information required under the rule, it must not be left blank under any circumstances. We hope this adequately clarifies OSHA's position.

MEMORANDUM FOR: REGIONAL ADMINISTRATORS

THRU: LEO CAREY, DIRECTOR Directorate of Field Operations

FROM: THOMAS SHEPICH, DIRECTOR Directorate of Compliance Programs

SUBJECT: Clarification of Material Safety Data Sheet Requirements Under the Hazard Communication Standard.


The following clarification relates to the Material Safety Data Sheet (MSDS) requirements of the Hazard Communication Standard (HCS), reference 29 CFR 1910.1200.

Paragraph (g)(3) of the standard requires that chemical manufacturers, importers and employers preparing a MSDS include explanatory statements in blank sections. Accordingly, preparers must mark blank sections with any words that convey the idea that the information was not applicable or not available.

The duty imposed under paragraph (g)(3) of the HCS has raised the question of whether a preparer can simply exclude a block from the MSDS rather than making an explanatory note?

Based on an interpretive reading of the standard, blocks or sections may be omitted in their entirety if no information is available or non-existent.

If you have any question regarding this clarification, please contact Roy Gibbs or Steve Simon on FTS 523-8036.
