apron. There will be no exceptions to this
rule!
Students often complain that goggles are
uncomfortable, hot, and funny looking….

but the alternative to goggles could be

3. Study your lab
assignment before you
come to class and have
your Pre Lab
completed. Pay
particular attention to
dangerous reagents or
special safety
precautions.
4. Never work in the lab without proper
supervision.
5. Never perform an
unauthorized experiment.
6. Never pipet by
mouth and never
inhale gases or
other vapors.
7. Be careful with glass equipment.
8. Never eat, drink or chew gum in any part
of the lab area.
9. Report any accident, injury, chemical spill
or inappropriate procedure at once.
10. Tie back long hair and secure loose
clothing.
11. Do not leave a
lit burner
unattended.
12. Read labels
of reagent
bottles
carefully before
using the
chemicals.
13. Never return unused chemicals to a
reagent bottle. Do not put a pipet, dropper
or spatula in a reagent bottle – pour the
reagent into a small beaker instead.
14. Always pour
acid slowly into
water to dilute –
never pour water
into acid.
(Remember: ADD
ACID)
15. Place broken glass, solid substances
and used chemicals in designated
container. Never throw a chemical down
the sink unless given permission by Mrs.
Hodgson.
16. Keep your lab area as clean as possible
at all times.
17. Wash your hands with soap and water
after each experiment.
18. To test the odor of a solution, do not
hold it directly under nose. Hold it away
and wave your hand over the solution
towards you. (wafting)
19. Use the
fumehood when
working with
volatile substances
or poisonous
vapors.
Emergency Situations
1. Spray fire extinguisher left to right at the
base of the flame. Where is the fire
extinguisher? ______________________
2. If clothing catches fire wall calmly to the
safety shower. If your lab partner’s
clothing catches fire use the fire blanket to
smother the fire. How do you use the
safety shower?_____________________
Where is the fire blanket?_____________
3. Corrosive chemicals
splashed on skin should be
flushed off promptly with
copious amounts of flowing
water for at least 15
minutes. If splashed on
clothing, the clothing must
be removed while under the
safety shower. Stay under
the shower for at least 15
minutes while Mrs. Hodgson
calls the nurse or 911.
4. A corrosive chemical in the
eye is a very serious matter.
Get to an eye wash fountain
immediately (within 15 seconds
if possible). Wash the eye for
at least 15 minutes while
someone else calls the nurse.
Keep the eyelid open fully;
move the eyeballs up, down,
left, right, criss-cross, round
and round. How do you use
the eye wash
fountain?________________
