Slide 1
Laboratory Safety
Slide 2
Safety in the laboratory
involves recognizing all
potential hazards and
an awareness of the
necessary precautions
connected with these
hazards.
Slide 3
Each person in a
laboratory is
responsible for the
safety of EVERYONE
working in the
laboratory
Slide 4
Accidents can cause
SERIOUS INJURY or even
DEATH. These accidents
can be anticiapted and
even prevented by being
aware of our classroom
environment and taking
responsibility for our
actions.
Slide 5
Follow all safety
procedures is key to
our personal
protection.
Slide 6
Three Fundamental ideas involved
in using a laboratory to carry out
experiments.
1. ALWAYS read the experiment before
conducting experiment.
2. ALWAYS use common sense when you are
working with laboratory apparatus and
materials.
3. In case of an accident know how to get help.
Slide 7
Goggles
Students must wear goggles at all
times while conducting
laboratory experiments. This is NJ
State Law.
Slide 8
Contact Lenses
Contact lenses should be
avoided in the laboratory.
Wearing them puts one at risk
for toxic or poisonous gases
being trapped inside the
contact causing the gas to be
in direct contact with your eye.
Slide 9
Locations of Emergency
Safety Equipment
Eye Wash
Fire Extinguishers
First Aid Kit
Fire Blanket
Slide 10
Never work in Laboratory alone
Your instructor should be within
your sights and hearing at all times,
so that if you can ask for help if you
have questions, difficulties, or
accidents.
Slide 11
Do ONLY the assigned
laboratory experiment.
Never substitute an
unauthorized
experiment for the one
your teacher assigns.
Do not deviate from
the procedures.
Slide 12
Proper Clothing
Wear
shoes that completely
cover your feet.
Tie
back long hair.
Gloves
and lab aprons/coats
may be necessary.
Slide 13
IMMEDIATELY report all
accidents to teacher, no matter
how minor.
Common accidents include:
Chemical spills
Ingestion of Chemicals
Cuts
Burns
Fire
Slide 14
No Mouth Contact with ANY
objects in the laboratory.
This applies to:
Pipettes
Reagents
Fingers
No Food or Beverages should
be present in Laboratory
Slide 15
Odors should be treated
with caution!
TOXIC
Chemicals primarily enter the
body through the respiratory
system. If you must smell a
chemical do not put directly over
the sample but gently WAFT the
vapors instead.
Slide 16
Neat, clean and clear of
unnecessary objects.
Backpacks, books and other items
not needed for work should be
placed in an area that doesn’t
interfere with the activity. Keep
work areas uncluttered and never
place chemicals or materials on
the floor.
Slide 17
Only use equipment that is
in good condition.
Glassware
that is cracked, chipped or
damaged goes in the glass boxes located at
the back of the classroom.
Inform
instructor of any equipment that is in
unsatisfactory condition.
(It is a good idea to keep excess electrical
cords taped to the work area or tied with rubber
bands to prevent you or a classmate from
tripping.
Slide 18
Spills must be cleaned up
immediately as directed by
teacher.
Dispose of rinses, reaction
mixtures and unused reagents
only as directed by instructor.
DO NOT throw anything down the
sink unless instructed to do so.
Slide 19
Avoid touching hot objects.
Heat can be generated through
chemical reactions so it is
imperative that you are cautious
when handling reaction vessels
during and after the reactions.
Objects that have been near
flames can be dangerous as well.
Slide 20
Immature Behavior has no
place in a laboratory setting.
The potential dangers posed by
such behavior are too great.
Slide 21
Read labels on reagent bottles
and containers to make certain
that they contain that
appropriate reagent for the
experiment.
Other symbols may also be found on
the bottle representing flammability,
reactivity, health concerns and other
potential dangers.
You will gain much insight to this
during Hazmat training.
Slide 22
Happy Hands
Use detergent or soap to wash
your hands thoroughly before you
leave the laboratory.
Slide 23
Laboratory is an important
part of this class. It is your
responsibility to maintain
proper conduct and apply
safety practices in the
classroom.
