  1. Safety

  2. Topics covered under Safety • Chemical Hazards • Chemical Exposure • Understanding Laboratory Equipment

  3. Chemical Hazards • Corrosives • Asphyxiants • Oxidizers • Alkalis

  4. Chemical Exposure • Inhalation • Ingestion • Injection • Absorption

  5. Chemical Exposure

  6. How can you avoid exposure?

  7. How can you avoid exposure? • Hands? • Eyes? • Clothes? • Face?

  8. How can you avoid exposure? • Procedurally • Use small amounts of chemicals • Follow directions exactly • Make sure equipment is not broken • Be aware of NFPA diamond information • Look up information on MSDS

  9. What if you are exposed to chemicals?

  10. What if you are exposed to chemicals? • Hands? • Eyes? • Whole body? • Ingested? • Inhaled?

  11. Shower and Eyewash • http://www.youtube.com/watch?v=7fZ3sle8o9k

  12. Prevention is better than cure • OSHA – Occupational Safety and Health Administration • NFPA diamond • MSDS – Material Safety Data Sheets

  13. Reading a NFPA diamond • Blue is for level of Health Hazard • Red is for level of Flammability • Yellow is for level of Chemical Reactivity • White is for special codes for unique hazards

  14. Reading a NFPA diamond • The blue, red and yellow portions will rate he hazard from 0 to 4 with 4 being the most dangerous. • The white “special notification” symbols include OX for oxidizer, W to symbolize an unusual or dangerous reaction with water or SA to signify Simple Asphyxiant gas

  15. Which would be more dangerous?
