What practices are followed to ensure safety in the laboratory?
Why?
Academic laboratory accidents are estimated to occur 10–50 times more frequently than chemical plant
accidents. Laboratory accidents often have unexpected outcomes that may result in permanent injury.
Dressing appropriately and following laboratory safety rules will reduce the incidence and severity of
accidents and help keep students safe.
1. Create a laboratory safety diagram in the space below by doing the following:
a. Sketch the outline of your laboratory room including all doors and windows.
b. Mark and label the position of the following laboratory safety equipment.
1. Fire blanket 6. Chemical disposal area
2. Fire extinguisher 7. Broken glassware disposal
3. Safety shower 8. Chemical spill clean-up kit
4. Eyewash station 9. Location of goggles
5. Fume hood 10. Location of gloves
c. Locate and read the evacuation instructions that are posted in your laboratory. Describe how
you should evacuate in case of an accident.
d. Label the fire exits in the diagram and add the evacuation route to your picture (this should
be posted in your room).

2. Biohazard materials are disposed of in biohazard bags when you are finished working with them.
a. On the diagram above, label where the bags are generally located.
b. What color are the bags?

Communication with your teacher in the laboratory can also help prevent accidents or injuries to yourself
and others. For example, you should always tell your teacher if you spill something or are cut or injured
when performing an experiment. You should also alert your teacher if any equipment or glassware is
broken. Your teacher can provide Material Safety Data Sheets (MSDS), which contain safety information
about chemicals you may come in contact with in the laboratory. Chemicals should be disposed of safely,
as directed by your teacher. Do not dump chemicals into the sink or trash.
10. Suppose you spill a chemical on yourself:
a. What information can your teacher provide for you concerning that chemical?
b. Where is the information located?
11. Why is it important to let your teacher know if you cut, burn or injure yourself when performing
an experiment?
12. Why should you tell your teacher if any equipment or glassware is broken?
13. Why should you never perform unauthorized experiments or ignore written directions for an
experiment?
14. Your teacher asks your group to create a list of ten rules that everyone must follow in the labora-
tory. What rules would your group include? After developing a list, send a representative from
your table to another group to compare responses.
