  1. 344 Organic Chemistry Laboratory Chemical and Laboratory Safety

  2. Chapter 1 in 344 lab manual MUST READ

  3. Pre-lab Discussion Session - Ask questions - Come prepared - Pre-lab questions/table completed

  4. Pre-lab ReagentTable PAGE 2-3 IN LAB MANUAL M aterial S afety D ata S heet (MSDS) CHEM 344 course website

  5. https://www.chem.wisc.edu/content/chemistry-344-experiments Available for every experiment

  6. https://www.chem.wisc.edu/content/chemistry-344-experiments Link to each MSDS

  7. This is an MSDS

  8. Pre-lab ReagentTable PAGE 2-3 IN LAB MANUAL M aterial S afety D ata S heet (MSDS) CHEM 344 course website KNOWTHE HAZARDS

  9. Wait for yourTA

  10. In the Lab COATS EVAC PLAN BAGS FIRE EXTINGUISHER

  11. In the Lab NO EATING NO DRINKING NO CHEWING

  12. In the Lab NO SMOKING

  13. NO DISTRACTIONS In the Lab

  14. NO DISTRACTIONS In the Lab IF IT BECOMES A PROBLEM, IT GOES

  15. NO DISTRACTIONS In the Lab IF IT BECOMES A PROBLEM, IT GOES

  16. Pre-lab ReagentTable PAGE 2-3 IN LAB MANUAL M aterial S afety D ata S heet (MSDS) CHEM 344 course website P ersonal P rotective E quipment (PPE)

  17. Personal Protective Equipment (PPE) Disposable Gloves (in lab only) Goggles Lab Coat Shoes covering entire foot

  19. Personal Protective Equipment (PPE)

  20. Eye Protection NO! Gloves? Lab Coat

  21. Prof. Barry Sharpless “I was quite literally unable to move a muscle before the tube exploded.” “Glass fragments shredded my cornea, penetrated the iris, and caused the partial collapse of one eye.” “There is never an adequate excuse for not wearing safety glasses in the lab at all times .” MIT Tech Talk, 1992, 23.

  22. THIS REALLY HAPPENED IN CHEM 344

  23. THIS REALLY HAPPENED IN CHEM 344 WHOAA! HNO 3 + PANTS

  24. THIS MIGHT HAPPEN IN CHEM 344 GRAZE CUT BURN EYES

  25. GET HELP TELL THE TA You are not in trouble You will not lose points

  26. Shower 3 shower stations in every lab 6 sinks in every lab IFYOU NEED IT USE IT!

  27. OUTSIDE MIDDLE LAB (B331) Eye wash ALSO IN B341

  29. Solvent Disposal In fume hood Non-Halogenated Solvents Diethyl ether Hexane Pentane Acetone (also dedicated drums) Methanol/Ethanol/Propanol Non- Halogenated Halogenated Halogenated Solvents Dichloromethane Chloroform HCl is not a halogenated solvent Aqueous solutions HCl, HNO 3 , H 2 SO 4 NaOH, KOH Bleach WASH INTO SINK

  30. Chemical and Lab Safety Your Responsibility Show up prepared every time Reagent table/pre-lab questions completed MSDS Lab procedure & waste disposal Always Use PPE Goggles, shoes, gloves in lab (Lab coat) Respect the chemicals Get Help Don’t hesitate, don’t panic, don’t be shy
