SAFETY IN THE LABORATORY

In AP Chemistry you will frequently perform laboratory activities. While no human activity is completely risk free, if you use common sense and a bit of chemical sense, you will encounter no problems. Chemical sense is an extension of common sense. Sensible laboratory conduct won't happen by memorizing a list of rules, any more than a perfect score on a written driver's test ensures an excellent driving record. The true "driver's test" of chemical sense is your actual conduct in the laboratory.

The following safety pointers apply to all laboratory activities. For your personal safety and that of your classmates, make following these guidelines second nature in the laboratory. Your teacher will point out any special safety guidelines that apply to each activity.

If you understand the reasons behind them, these safety rules will be easy to remember and to follow.

SAFETY ASSIGNMENT:

1. Read all of the safety guidelines.

2. Sign these safety rules at the bottom

3. In ink, put your name, date, and period on a sheet of binder paper.

4. With your partner, for each listed safety guideline(yes, you each have to do all 19 of them!):

a) Write in your own words what the safety rule says

5. Turn in your work stapled with your partner’s work. This must be on file before you begin lab work.

6. This work is due today.

HOMEWORK:

7. Finish the safety re-write, if you do not finish in class. Take home this safety contract and have your parents read and sign.

Rules of Laboratory Conduct.

1 . Perform laboratory work only when your teacher is present. Unauthorized or unsupervised laboratory experimenting is not allowed.

2. Your concern for safety should begin even before the first activity. Always read and think about each laboratory assignment before starting.

3. Listen at the start of any lab for any specific cautions that the teacher may describe for a particular lab activity.

4. Know the location and use of all safety equipment in your laboratory. These should include the safety shower, eye wash, first-aid kit, fire extinguisher, and blanket.

5. Wear an apron and protective glasses or goggles for all laboratory work. Tie back loose hair. And wear shoes (rather than sandals).

6. Clear your benchtop of all unnecessary material such as books and clothing before starting your work.

7. Check chemical labels twice to make sure you have the correct substance. Some chemical formulas and names may differ by only a letter or a number.

8. You may be asked to transfer some laboratory chemicals from a common bottle or jar to your own test tube or beaker. Do not return any excess material to its original container unless authorized by your teacher.

Rules of Laboratory Conduct (cont.)

9. Avoid unnecessary movement and talk in the laboratory.

10. Never taste laboratory materials. Gum, food, or drinks should not be brought into the laboratory.

11. If you are instructed to smell something, do so by fanning some of the vapor toward your nose. Do not place your nose near the opening of the container. Your teacher will show you the correct technique.

12. Never look directly down into a test tube; view the contents from the side. Never point the open end of a test tube toward yourself or your neighbor.

13. Any laboratory accident, however small, should be reported immediately to your teacher.

14. In case of a chemical spill on your skin or clothing rinse the affected area with plenty of water. If the eyes are affected, water-washing must begin immediately and continue for 10 to 15 minutes or until professional assistance is obtained.

15. Minor skin burns should be placed under cold, running water.

16. When discarding used materials, carefully follow the instructions provided.

17. Return equipment, chemicals, aprons, and protective glasses to their designated locations.

18. Before leaving the laboratory, make sure that gas lines and water faucets are shut off.

19. If in doubt, ask!

I have read and understand the AP Chemistry lab safety rules above. I realize that my cooperation is important to the safety of everyone in the lab.
