2. Although many chemicals used in this course are not inherently toxic, all chemicals and solutions should be treated as if they are potential toxins. Therefore, NEVER put anything in your mouth in the laboratory. No eating, drinking, smoking, gum chewing, application of cosmetics is allowed in the laboratory, unless specifically related to physiology lab.

3. Disposable gloves should be worn to protect the hands when handling all caustic or carcinogenic materials. If you contaminate your gloves while handling these kinds of materials, please change them immediately. Reduce the potential for contamination of areas outside the lab by removing your gloves and washing your hands before leaving the laboratory. This includes working with animals, caustic chemicals or any other potential contaminating equipment.

4. Do not store backpacks, purses, or books that are not required for performing the experiment on top of the bench where you are working to minimize the opportunity to spill things on your personal belongings. The room is fairly small; you might want to make use of lockers in this converted middle school building.

5. Be aware of locations of (and know how to use) the
Fire extinguisher (in room beside door, and in various locations in hall)
Eye wash station (in room beside door, or out in hall, turn left, it is orange)
Deluge shower (out in hall, turn left, it is orange))
Chemical spill kits (between rm 324 and rest rooms)

6. Always double-check the label of any chemical that you use.

7. Always report any accidental spills, burns, cuts, fires, etc. IMMEDIATELY to your instructor. If a spill occurs, cover the spill with paper towels to prevent the spill from spreading.

8. Discard chemicals, biological materials, and paper as directed by your instructor.

9. Avoid shorts, skirts, or open-toed sandals in the lab as it increases the likelihood for chemical exposure to skin in the case of a spill. If you have a lab coat and/or safety glasses, we encourage you to wear them. The biology department also has a few lab coats that you may borrow during lab.

10. Please report any damaged or defective equipment to your instructor as soon as possible so that we may repair or replace it.

11. Please dispose of
All glass in specially-marked cardboard boxes (in the lab room near the door)
Metal sharps (needles, razor blades, etc.) in the plastic sharps waste container.

12. If you are in doubt, or if you have a question, please ASK!
