What’s the difference between a SDS and a MSDS?

There are two basic differences between an SDS and the old-fashion MSDS.  The SDS requires 16 elements and they must be in a specified order as they are listed in the table below.  An old-fashioned MSDS did not specify the order and it did not require the same set of 16 elements.  For a full description of the differences, see the table below.

The table below is from OSHA’s website and was edited to show just the comparison between GHS and OSHA.  For the full table, go here http://www.osha.gov/dsg/hazcom/ghs.html#a

Appendix A

Comparison of MSDS/SDS Elements

The following tables provide a comparison of MSDS elements for the following:

  • Globally Harmonized System1
  • ISO Safety Data Sheet for Chemical Products 11014-1: 2003 DRAFT 2
  • ANSI MSDS Preparation Z400.1- 2004 3
  • OSHA Hazard Communication Standard 29#CFR#1910.12004

  • Other hazards which do not result in classification (e.g., dust explosion hazard) or are not covered by the GHS.
  • health hazards including acute and chronic effects, listing target organs or systems
  • signs & symptoms of exposure
  • conditions generally recognized as aggravated by exposure

3. Composition/in-formation on ingredientsSubstance

  • Chemical identity
  • Common name, synonyms, etc.
  • CAS number, EC number, etc.

Mixture

  • The chemical identity and concentration or concentration ranges of all ingredients which are hazardous within the meaning of the GHS and are present above their cut-off levels.
  • Cut-off level for reproductive toxicity, carcinogenicity and category 1 mutagenicity is ³ 0.1%
  • Cut-off level for all other hazard classes is ³ 1%

Note: For information on ingredients, the competent authority rules for CBI take priority over the rules for product identification

  • Chemical and common name of ingredients contributing to known hazards
