MSDSMaterial Safety Data Sheet

• properties of a particular substance
• procedures for handling, storing, disposing or
  working with that substance in a safe manner
• physical data (melting point, boiling point,
  flash point, etc.), toxicity, health effects,
  first aid, reactivity,
• format of an MSDS can vary from source to source
  (click here for an example)

7
MSDS where do you find them?

• Every chemical supplier (Sigma, Spectrum) must
  provide an MSDS for each product.
• Consumers can see a copy of MSDS if one knows the
  compounds name.
• Available online
• www.chemistry.pomona.edu has a link to moldata
  and environmental chemistry
• www.sigma-aldrich.com
• Google, Wikipedia
