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 the workplace. 

Every person who works with hazardous materials at Wellesley College should:

  • be aware of what a SDS is and it's relevance to your health & safety.
  • be aware of how to access SDS's for your work area/laboratory.
  • maintain SDS's that are received with incoming chemical shipments and have them readily available for employees/students. Electronic access is also acceptable.

Information contained on an SDS is divided into 16 sections:

  • Identification
  • Hazard(s)
  • Composition/Information on Ingredients
  • First-Aid Measures
  • Fire-Fighting Measures
  • Accidental Release Measures
  • Handling and Storage
  • Exposure Control/personal protection
  • Physical and Chemical Properties
  • Stability and Reactivity
  • Toxicological Information
  • Ecological Information
  • Disposal Considerations
  • Transport Information
  • Regulatory Information
  • Other Information to include date of preparation or last revision
