C239 Laboratory Safety Rules
1. Many things happen in the lab, and you can never be sure how your area has
been used, or whether it was properly cleaned up. Because of this, and possible
contamination from the animals, you should not bring food or drink into the lab
with you! Also, don't put anything that's come in contact with the lab table -
pens, pencils, fingers, etc. - into your mouth or eyes.
2. Be on time! There are several ways being late can hurt your grade directly, but
there are safety considerations as well - lab instructions, including safety items,
are gone over at the beginning of the labs.
3. It's always a good idea to look your lab exercise over ahead of time, and make
notes of the modifications and warnings given at the beginning of the class.
4. Any time you're not sure, ask!!
5. Wash your hands before and especially after working in the lab.
6. There are drawers and coat hooks available - keep all unnecessary objects out of
your and other people's way.
7. Although labs rarely involve dangerous materials, some can have lasting effects
on clothing, so you might want to bring a protective cover-up. With some
procedures, protective eye coverings will be required. If you have long hair or
dangling jewelry, keep them out of your working materials.
8. Clean up your stuff! Your area should look at the end of your lab like it did
when you started. When in groups, everyone is responsible for clean-up.
Points may be lost if this is not done.
9. When working with chemicals or cultures, make sure you do not mix things
together in the source glassware - that includes droppers and mixing rods.
It is not always safe to mix tap water into materials by washing them, either.
10. Dispose of all waste materials properly. The wastebasket is near the door.
Broken glass does not go into the wastebasket - there's a special box for
it next door in the prep room. Notify the instructor any time something gets
broken or if you're injured, even mildly.
11. Try to always stay alert while you're in the lab. Know where the emergency
equipment - first aid kit, fire extinguisher, eyewash fountain, etc - are (most
are on the front wall or just across the hall). Know the appropriate route out
of the building during an emergency.
