Appropriate
Student
Behavior
Never Eat in
the
Laboratory
• No running
• No horseplay
• No unauthorized
experimentation
• Never, under any
circumstance,
look directly into
the sun
• It is not safe to
eat anywhere in
the laboratory
• There could be
trace residues of
poisonous
chemicals that
could cause you
to become ill.
Electrical
Outlets
• Electrical outlets near
water sources must be
GFI outlets
• GFI - ground fault
interrupter – current is
interrupted to prevent
electrical shock.
• Always check for rips in
electrical cords before
the lab begins, report
any frayed wires to the
teacher (replaced or
fixed by teacher)
• When removing a plug
from the outlet, grab
the plug not the cord.
Proper

• When working in the
laboratory students
should wear

Accidents
• Most accidents can be prevented if you make
safety a habit.
• The best way to prevent an accident is to keep
your work station clean
• Reading all parts and directions of a lab before
beginning will prevent:
– mixing the wrong things together
– using the wrong equipment
• Never work alone
• If you get something in your eyes – wash eyes
from the inside toward the outside.
• If you get acid on your hands, notify the
teacher and quickly rinse for several minutes
with water.

Requirements
• Two exits (windows don’t
count)
• Fire extinguisher – point
toward the base of fire
• Fire blanket
• Eye wash station
Laboratory Equipment
Very Important
Know lab equipment and its capabilities
so you can carry out the lab in an
organized fashion
Gather all equipment prior to beginning
the lab to minimize travel during the
experiment
