  • 3. Study your lab assignment before you come to
    class and have your Pre Lab completed. Pay
    particular attention to dangerous reagents or
    special safety precautions.

10
  • 4. Never work in the lab without proper
    supervision.

11
  • 5. Never perform an unauthorized experiment.

12
  • 6. Never pipet by mouth and never inhale gases
    or other vapors.

13
  • 7. Be careful with glass equipment.

14
  • 8. Never eat, drink or chew gum in any part of
    the lab area.

15
  • 9. Report any accident, injury, chemical spill
    or inappropriate procedure at once.

16
  • 10. Tie back long hair and secure loose
    clothing.

17
  • 11. Do not leave a lit burner unattended.

18
  • 12. Read labels of reagent bottles carefully
    before using the chemicals.

19
  • 13. Never return unused chemicals to a reagent
    bottle. Do not put a pipet, dropper or spatula
    in a reagent bottle pour the reagent into a
    small beaker instead.

20
  • 14. Always pour acid slowly into water to dilute
    never pour water into acid. (Remember ADD
    ACID)

21
  • 15. Place broken glass, solid substances and
    used chemicals in designated container. Never
    throw a chemical down the sink unless given
    permission by Mrs. Hodgson.

22
  • 16. Keep your lab area as clean as possible at
    all times.

23
  • 17. Wash your hands with soap and water after
    each experiment.

24
  • 18. To test the odor of a solution, do not hold

    substances or poisonous vapors.

26
Emergency Situations
  • 1. Spray fire extinguisher left to right at the
    base of the flame. Where is the fire
    extinguisher? ______________________

27
  • 2. If clothing catches fire wall calmly to the
    safety shower. If your lab partners clothing
    catches fire use the fire blanket to smother the
    fire. How do you use the safety
    shower?_____________________ Where is the fire
    blanket?_____________

28
  • 3. Corrosive chemicals splashed on skin should
    be flushed off promptly with copious amounts of
    flowing water for at least 15 minutes. If
    splashed on clothing, the clothing must be
    removed while under the safety shower. Stay
    under the shower for at least 15 minutes while
    Mrs. Hodgson calls the nurse or 911.

29
  • 4. A corrosive chemical in the eye is a very
    serious matter. Get to an eye wash fountain
    immediately (within 15 seconds if possible).
    Wash the eye for at least 15 minutes while
    someone else calls the nurse. Keep the eyelid
    open fully move the eyeballs up, down, left,
    right, criss-cross, round and round. How do you
    use the eye wash fountain?________________
