  1. Material Safety Data Sheets

  2. Session Objectives • You will be able to: • Recognize the importance of the MSDS • Access an MSDS • Locate essential safety and health information • Interpret the information accurately

  3. What You Need to Know • Purpose of the MSDS • How to access an MSDS • How to find and interpret essential safety and health information • How to use MSDS information to protect against chemical hazards

  4. Right to Know • Hazard Communication Standard • Right-to-know information • MSDS and your right to know

  5. MSDS and Hazard Communication • Chemical manufacturers • Employers • Employees

  6. MSDS—The Foundation of Chemical Safety • The MSDS tells you: • What chemicals are contained in a product • What the hazards are • What precautions you need to take • What to do in the event of a spill or exposure

  7. Accessing an MSDS • Chemical list as index to MSDS system • Binder system • Computer-generated MSDSs

  8. MSDS Formats • Different formats permitted • Section numbers and titles may vary • Same basic information provided regardless of format

  9. Importance of the MSDS • Do you understand the information that has been presented so far?

  10. Product Information • Manufacturer name, address, and phone number • Emergency phone number • Name of chemical • Date of MSDS

  11. Chemical Ingredients • Hazardous chemical names • Percentage of chemical in product • Nonhazardous ingredients • Trade secrets

  12. Exposure Limits • PEL (Permissible Exposure Limit) • STEL (Short-Term Exposure Limit) • TLV (Threshold Limit Value)

  13. Physical Properties • Boiling point and melting point • Vapor pressure and evaporation rate • Vapor density • Solubility in water and specific gravity • How chemical looks and smells under normal conditions

  14. Health Hazards • Routes of entry • Health effects and symptoms of exposure • Effect on existing medical conditions • Target organs

  15. Fire and Explosion Data • Flashpoint • Flammability limits • Hazardous combustion products

  16. Fire Data (cont.) • Extinguishing measures • Firefighting equipment and methods

  17. Reactivity Information • Chemical stability • Conditions to avoid • Incompatibility with other substances

  18. Reactivity Information (cont.) • Hazardous decomposition products • Hazardous polymerization

  19. Safe Handling Precautions • Storage recommendations • Dispensing requirements

  20. Safe Handling Precautions (cont.) • Handling instructions • Warnings • Decontaminant or antidote • Disposal requirements

  21. Exposure Control • Engineering controls • PPE • Hygiene

  22. Spills and Leaks • Evacuation and isolation of area • Evaluation by trained responders • Containment • Cleanup

  23. First Aid • Eyes • Skin • Inhalation

  24. First Aid (cont.) • Ingestion • Notes to physician

  25. Basic MSDS Information • Do you understand all the information that was presented in the previous slides?

  26. Additional Information • Ecological • Toxicological • Transportation • Regulatory

  27. Label Information • Health = Blue • Flammability = Red • Instability or Reactivity = Yellow • Other hazards or special handling = White • Scale: 0 (no hazard) to 4 (extreme hazard)

  28. Key Points to Remember • The MSDS is the foundation of chemical safety • MSDSs must be accessible at all times • Always read the MSDS before working with a chemical • Ask a supervisor if you still have questions about hazards or precautions
