Material Safety Data Sheets contain information under the following specific headings:

  • Identification of the substance or preparation (a preparation is a mixture of substances) and the name of the supplying company.
  • Composition/information on ingredients.
  • Hazards Identification.
  • First-aid measures.
  • Fire-fighting measures.
  • Accidental release measures.
  • Handling and storage
  • Exposure controls/ personal protection.

·  Physical and Chemical properties
·  Stability and reactivity
·  Toxicological Information.
·  Ecological Information.
·  Disposal considerations.
·  Transport information
·  Regulatory Information
·  Other Information.

 

The relevant safety data sheets must be read before you carry out your experiments. It is advisable to keep a hardcopy at hand when you are carrying out your experiment, in case of any emergencies. Check for incompatible chemicals at Bretherick’s Handbook of Reactive Chemical Hazards available as an e-book at the Library.
