SAFETY
is the
RESPONSIBILITY
of EVERYONE!
Safety First
 Science is a class that involves many interesting and exciting laboratory
activities intended to help you learn and discover!
 However, the laboratory activities will require the use of unfamiliar items
such as chemicals, specialized tools, organisms, and expensive lab
equipment.
 Safety in the science classroom is the #1 priority. This will ensure that
students learn without injury and the science laboratory experience is
available for all students.
 To ensure a safe science classroom, a list of rules has been developed and
provided to you in your Safety Agreement.
 These rules must be followed at all times.
 A signed Safety Agreement is required to participate in laboratory activities.
 A student will be removed from the science laboratory immediately for his/her
personal safety and the safety of all other students if the rules in the Science
Laboratory Safety Rules are not followed.

Personal
Safety
 To keep ourselves safe, we must take safety precautions in the science
laboratory:
 Wash your hands with soap and water before and after the science
laboratory activity.
 Never eat, drink, chew gum, or taste anything in the science
laboratory.
 Never put on makeup or Chap Stick in the science laboratory.
 Keep hands away from face, eyes, and mouth while using science
laboratory materials.
 When directed to “sniff” in the lab, do not place nose over item.
Follow the teacher’s directions for “wafting” the odor to the nose.
Personal
Safety
 Wafting:
 Hold the substance in one hand.
 Wave your other hand over the
container towards your face.
 Gently sniff.
Safety
Equipment
 Wear and use safety equipment including
goggles, gloves, and safety tongs or
mittens.
 Never remove safety goggles during
a science laboratory activity. There
are no exceptions to this rule!
 Cold or very hot materials can only be
touched with heat safety items such
as safety tongs, safety mittens, or
rubber gloves.
 Wear safety gloves and do not
remove the gloves unless instructed

Goggle Song
The "Goggle Song" is sung to the tune of "I'm a Little Teapot."
I'm a little scientist, short and stout.
Here are my goggles, here are my eyes.
When I don't wear my goggles, my teacher shouts,
PUT THEM ON OR YOU GET OUT!

Accidents
 Report any accident (spill, breakage,
etc.), injury, or broken equipment to
the teacher immediately.
 Students should not clean up spills or
broken items! Let the teacher know so
that the teacher or custodian can take
care of the spill or broken glass.
 Glass should be used cautiously and
chipped, cracked, or scratched
glassware should never be used.
Clean Up
 It is expected that laboratory students
will clean all work areas and
equipment at the end of a laboratory
activity.
 This means…
 Dispose properly of any and all
waste materials.
 Properly clean and store glass.
 Properly store equipment,
materials, and specimens.
 Clean work area.
 Wash hands.
Clean Up
 Waste Disposal:
 First ask your teacher where
and how to dispose of
waste.
 Never pour anything down
the drain unless you are
told to do so.
 A waste bottle will be
supplied for substance that
cannot go down the drain.
Emergency
 Learn how to handle
emergency
situations.
Remember –
 If you have an
emergency situation,
yell:
Help
Emergency
 Learn where the safety equipment is located
and how to use it.
 Fire Extinguisher:
 There is one fire extinguisher at the front of
the classroom. There is another fire
extinguisher in the hallway outside the front
door of the classroom.
 There are three doors in the classroom that
you can exit from in the event of a fire.

What’s Wrong With This Picture?
What’s Wrong With These Statements?
 Mohammad says that his teacher is solely responsible for preventing
laboratory accidents.
 Keshia started the laboratory activity before reading it through
completely.
 Ricardo decided to see what would happen if he mixed the two
substances even though the laboratory activity did not say to do so.
 Stephanie says that the safety goggles mess up her hair and give her
raccoon eyes. She takes them off when the teacher is not looking.
 Alex and Tasha accidentally break a beaker full of some chemical.
Instead of risking getting in trouble, they quickly clean up the mess
with paper towel and throw it in the garbage.
