Rule # WALK
When going into the lab make sure to
WALK. There will be no running in the
lab. There will be materials and
equipment out that can break if you
accidently knock into them. There may
be electrical wires on the ground that
you may trip over as well. Please WALK
and be careful.
RULE # HANDLING CHEMICALS
When handling chemicals during lab it is important to
proceed with caution. Wear gloves whenever pouring
chemicals or handling them. If you have to dispose of
chemicals, always use the waste containers provided
on your lab tables. NEVER pour the chemicals back
into the container you got it from. If you do, whatever
was in your container could cause a chemical
reaction with the chemical in the original container.
Never smell a chemical directly. You can waft or fan
the fumes toward yourself. You can do this by waving
your hand over the flask or beaker.
RULE # HANDLING EQUIPMENT
It it important that when you are using
different lab equipment, you handle them
with care. Microscopes should be held with
both hands, one underneath and one on
the arm. When handling glassware be sure
to hold it with both hands when can. If
something is hot, then make sure to use
tongs. NEVER use your hands.
RULE # EYE WASH/SHOWER
If chemicals or particles get in your eyes, WALK to the
eye wash station and rinse out your eyes for 15
minutes. Make sure that you keep your eyes OPEN
when you rinse them.
If chemicals get onto your skin, WALK to the shower
station and pull on the red handle. Stand under the
shower and rinse off your body for 15 minutes.
ALWAYS make sure to tell the teacher when
something like this happens when in academic
RULE # FIRE SAFETY
In the event that there is a fire during
lab, WALK over to the fire extinguisher, pull
out the safety pin, aim the nozzle towards the
fire and push the handle .Empty out the
N.B: skills for usage are very important.
RULE # NO EATING/DRINKING IN LAB
There will be NO eating or drinking during lab. The lab
tables may have had chemicals on them previously
that were not properly cleaned up so you should not
eat or drink on them either.
Sometimes we will be using food as materials in lab,
this too should not be eaten unless I tell you it is
ok. The food may have been stored next to chemicals
in the lab and could be contaminated.
RULE # CLEANING UP
Once lab is over, enough time to clean your lab table
is important. If you used any chemicals make sure to
dump them into the waste container at your lab
table. DO NOT POUR THEM DOWN THE SINK! Once the
beaker, flask, or test tube is empty then you can rinse
it out in the sink at your lab table and use the brush to
wash it. PLEASE ONLY TURN THE FAUCET ON DURING
CLEAN UP TIME! Make sure you sponge down your lab
area as well. Any materials like microscopes or petri
dishes will be put back where they belong.
Before leaving the lab ALWAYS wash your
hands. Make sure you use soap and water and scrub
your hands thoroughly at the hand washing
station. Some of the materials we will be using could
be harmful to you, so it is important that you wash your
hands so you do not get sick.
