Safety in the Laboratory
1. Perform laboratory work only when your
teacher is present. If you would like
to try something “creative” ask your teacher if it is safe and do it
under her supervision.
2. Never use the
distilled water wash bottles to squirt another person .
3. Know
the location and use of the safety shower, eye wash, first-aid
kit , fire extinguisher, and fire
blanket.
4. Wear a laboratory apron and protective
glasses for laboratory work. Wear shoes (rather than sandals) and tie back
loose hair.
5. Keep textbooks, extra clothing, food and beverages off the lab
tables.
6. Check chemical labels twice to make sure you have the correct
substance. Some chemical formulas and names may differ by only a letter or number.
7. 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.
8. Avoid unnecessary movement and talk in the laboratory.
9. Never taste laboratory materials. Gum, food or drink may not be brought into the laboratory.
10. If you are instructed to smell soothing, 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.
11. Never look directly down
into a test tube; view the contents from the side. Never point the open end
of the test tube toward yourself or your neighbor.
12. Any laboratory accident,
however small, should be reported immediately to your teacher.
13. 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 continued for 10-15 minutes or until professional assistance
is obtained.
14. Minor skin burns should be placed under cold, running water.
15. When discarding or disposing of used materials, carefully follow
the instructions provided.
16. Return equipment, chemicals aprons and protective goggles to
their designated locations.
17. Before leaving the laboratory, make sure that gas lines and water
faucets are shut off.
18. Wash your hands before leaving the laboratory.
19. If you are unclear or
confused about the proper safety procedures, ask your teacher for clarification.
If in doubt, ask!
I have read the greensheet and safety rules and agree
to show respect and comply with all safety rules. I understand that if my behavior in the
chemistry lab is considered unsafe by my teacher, I will be asked to sit down
and earn a grade of zero on that lab.
Repeated infractions will result in my removal from the class.
