Safety Data Sheets (SDS)

Safety Data Sheets (SDSs)

There are many ways to locate the SDS for chemicals or products of concern. The preferred method is to make sure to keep the SDS that came with the product and keep where it can easily be located for reference. Whenever possible, retain this copy in a binder, or scan and save it as an electronic copy to insure that you have the most relevant SDS for your products.
NOTE: It is the responsibility of the individuals ordering hazardous materials to obtain and store a copy of the associated safety data sheet. If not available online, personnel may contact the vendor to request the SDS of interest.
Listed below are some common chemical suppliers, searchable databases, as well as safety information pages. The following sources provide SDSs that are free to the public. (Wellesley College no longer subscribes to MSDSonline for SDS access.)

Background Information

Safety Data Sheets (SDS) are developed by chemical manufacturers to provide information for each hazardous chemical they produce.

SDSs are a component of OSHA's Hazard Communication and Laboratory Standards. Both standards states that employees have a right to know what hazards are associated with chemicals used in their workplace.

Information contained on an SDS is divided into 16 sections:

  1. Identification
  2. Hazard(s)
  3. Composition/Information on Ingredients
  4. First-Aid Measures
  5. Fire-Fighting Measures
  6. Accidental Release Measures
  7. Handling and Storage
  8. Exposure Control/personal protection
  9. Physical and Chemical Properties
  10. Stability and Reactivity
  11. Toxicological Information
  12. Ecological Information
  13. Disposal Considerations
  14. Transport Information
  15. Regulatory Information
  16. Other Information to include date of preparation or last revision
