  • 1. MSDS Material Safety Data Sheets Every Company That Manufactures Hazardous Chemicals in the U.S. Must Prepare One.
  • 2. MSDS • Mandated by OSHA in their Hazard Communications Standard (HCS). • Purpose: “to ensure that the hazards of all chemicals produced or imported are evaluated, and that information concerning their hazard is transmitted to employers and employees.”
  • 3. Contents of MSDS • Chemical Identity (title of MSDS)- provides identity of chemical as it is found on the label. • Section I. Manufacturer’s name and contact info – Name – Address – Phone – Emergency phone numbers – Date MSDS was prepared
  • 4. Contents of MSDS • Section II. Hazardous Ingredients/Identity Information – Trade names – Synonyms – Chemical Abstract Service (CAS) number – Chemical family (general type of chemical: acid, organic etc.) – Molecular formula – Molecular weight
  • 5. Components of MSDS • Components and Contaminants – In some MSDS you’ll see a list of components of the material – This info helps you understand whether or not the chemical/product poses a significant toxic hazard. – Lists OSHA PEL (Permissible Exposure Limit): the lower the limit the more toxic the chemical is. – SARA Title III (Community Right to Know Law) notation.
  • 6. Components of MSDS • Section III. Physical/Chemical Characteristics – Appearance – Odor – Boiling Point – Specific Gravity (Water = 1) – Vapor pressure (mm HG) – pH (less than 7 = acidic, greater than 7 = basic, 7 = neutral) -Melting point -Vapor density -Evaporation rate -Solubility in water
  • 7. Components of MSDS • Section IV. Fire and explosion hazard data – Flash point – Flammable limits – Extinguishing media – Special fire fighting procedures – Unusual fire and explosion hazards
  • 8. Components of MSDS • Section V. Reactivity Data – Provides information about potential problems in mixing or storing the chemical with another • Reactivity hazards • Storage or usage conditions to avoid • Warnings about incompatibles
  • 9. Components of MSDS • Section VI. Health Hazard Data – Details • Routes of entry (inhalation, skin, ingestion) • Health hazards (acute = immediate, chronic = build up over time) • Carcinogenicity • Signs and symptoms of exposure • Medical conditions aggravated by exposure • Emergency and First Aid
  • 10. Components of MSDS • Section VII. Precautions for Safe Handling and Use – Provides instructions for • safe storage • Use • Disposal • What to do in case of spill or environmental release
  • 11. Components of MSDS • Section VIII. Control Measures – Respiratory protection (must be trained and fitted) – Ventilation (local, mechanical exhaust, or other) – Protective gloves – Eye protection – Other PPE (Protective Personal Equipment)
