Please read these safety regulations carefully, and be sure that you understand them. Additional safety precautions will be discussed before each laboratory experiment if additional hazards exist.

YOUR EYES:

1. Always wear safety goggles and protective clothing in the laboratory. The goggles must protect your eyes against both impact and splashes.

2. If you should get a chemical in your eyes wash the eyes immediately with flowing water from one of the eyewash stations available in the laboratories. The washing should continue for 15 to 20 minutes. Send someone else to notify the instructor if he has not seen the accident.

3. It is not recommended to wear contact lenses in the laboratory. Students are especially cautioned about the soft type of contact lenses, since vapors tend to collect at the surface of the eye. If you decide to disregard this recommendation and still wear contact lenses in the laboratory, you must put a green dot on the top of your safety goggles to signify to the instructor that in the event of an accident the contact lenses must be removed.

TASTE AND ODOR:

4. Nothing is ever to be tasted in the laboratory. This means, of course, that one must not eat, drink, or smoke at any time in the laboratory.

5. Do not use your mouth to fill pipettes; always use a suction bulb or apparatus.

6. Be very careful when noting odors, and avoid breathing any fumes. Desk hoods are available to remove fumes; be certain that yours is open and working.

7. All chemicals must be considered to be hazardous, i.e., flammable, toxic, and corrosive, unless instructed otherwise. When in doubt, assume the worst and use the hood and shields.

SKIN CONTACT:

8. Never point a test tube toward another person or toward yourself, for the contents may bump. This is especially true of solutions being heated.

9. Always pour acid into water when preparing dilute acid solutions. If you make the addition the other way, the added water with some acid may boil out and splash on you.

10. If corrosive acids, bases or other chemicals come into contact with your skin, wash them off immediately with lots of water. Summon the laboratory instructor while you are washing the spilled chemical off. In some cases of concentrated or particularly hazardous chemicals, gloves, aprons, face shields, and other protective equipment must be worn.

GLASS:

11. Do not force glass tubing into corks or rubber stoppers. Lubricate the tubing with glycerine or water and introduce the glass gradually and gently. Always us a cloth towel or cloth to protect your hands when you insert tubing into rubber.

12. Place all hot glassware on a wire gauze to cool and never hand hot glass to another person. Hot and cold glassware look exactly the same.

ACTIONS IN THE LABORATORY:

13. Never work alone in any laboratory. Visitors are not allowed in the laboratory without the instructor's permission. You must obtain the instructor's permission before working in the laboratory at times other than the regularly scheduled periods.

14. Do not perform any unassigned or any unauthorized experiments.

15. Never participate in horseplay in the laboratory.

16. Read the label carefully before removing a chemical from its container. Never return an excess of any chemical to its original container. Always leave the excess in a labeled beaker near the original container for another student to use. Use these excesses first. If physical appearances indicate contamination or mislabeling, do not use the chemical and alert the instructor.17. Be cautious when lighting a burner. Keep your face and hair away from the flame.

18. Keep your work area clean. Keep the balances clean. Always clean up spilled chemical and broken glass immediately. Summon the instructor if you are in doubt as to how to clean up or dispose of a chemical.

19. Use proper safety equipment and precautions when transporting chemicals, especially the concentrated acids and bases.

20. In each laboratory that you use, note the locations of sink and water faucets. The first aid kit is available in room 117-A. For emergency , call the campus police at 2091.

21. Always wash your hands thoroughly before leaving the laboratory.

PERSONAL APPEARANCE:

22. You must wear clothing that adequately protects your body. The following do not provide sufficient protection and cannot be worn in the laboratory: barefeet, sandals or open-toed shoes, shorts.

23. Long hair must be confined when working in the laboratory. It must not be able to fall into chemicals or flames. {If you wear a tie, it too must be confined.}

IN THE EVENT OF AN ACCIDENT:

24. Report all accidents no matter how minor to your instructor immediately.

DISPOSAL OF CHEMICALS:

25. Only non-toxic, dilute, water soluble compounds may be disposed of by placing them in the sink drains. All other chemicals must be disposed of in the labeled containers available in the laboratory. In order to facilitate the proper subsequent disposal of chemicals, you must separate them by categories and record them on the disposal inventory attached to each container. The appropriate waste container will be provided for each experiment. In general organic wastes are separated by halogenated and non-halogenated, and inorganic wastes are separated into heavy metals, toxins, and corrosives.

26. Dispose of broken glassware only in the specially designed, orange containers. Do not discard anything else in these containers.

PREGNANCY:

27. Because of the present-day ignorance of information regarding the teratogenic effects of chemicals, anyone who is pregnant and plans to carry the child to term must withdraw without penalty from this class. Please see the instructor and the Dean of Students.
