Unformatted text preview: STUDENT SAFETY ACKNOWLEDGEMENT
PURPOSE Science is a hands-on laboratory class. You
will be doing many laboratory activities,
which require the use of hazardous
chemicals. Safety in the science classroom is
the #1 priority for students, teachers, and
parents. To ensure a safe science classroom,
a list of rules has been developed and
provided to you in this student safety
acknowledgement. These rules must be
followed at all times. Two copies of the
acknowledgement are provided. One copy
must be signed by both you and a parent or
guardian before you can participate in the
laboratory. The second copy is to be kept in
your notebook as a constant reminder of the
safety rules. GENERAL RULES 1. Conduct yourself in a responsible manner
at all times in the laboratory.
2. Follow all written and verbal instructions
carefully. If you do not understand a
direction or part of a procedure, ask the
instructor before proceeding.
3. Never work alone. No student may work in
the laboratory without an instructor present.
4. When first entering a science room, do not
touch any equipment, chemicals, or other
materials in the laboratory area until you are
instructed to do so.
5. Do not eat food, drink beverages, or chew
gum in the laboratory. Do not use laboratory
glassware as containers for food or
6. Perform only those experiments
authorized by the instructor. Never do
anything in the laboratory that is not called

instructor. Carefully follow all instructions,
both written and oral. Unauthorized
experiments are prohibited.
7. Be prepared for your work in the
laboratory. Read all procedures thoroughly
before entering the laboratory.
8. Never fool around in the laboratory.
Horseplay, practical jokes, and pranks are
dangerous and prohibited.
9. Observe good housekeeping practices.
Work areas should be kept clean and tidy at
all times. Bring only your laboratory
instructions, worksheets, and/or reports to
the work area. Other materials (books,
purses, backpacks, etc.) should be stored in
the classroom area.
10. Keep aisles clear. Push your chair under
the desk when not in use.
11. Know the locations and operating
procedures of all safety equipment including

located. 12. Be alert and proceed with caution at all
times in the laboratory. Notify the instructor
immediately of any unsafe conditions you
13. Dispose of all chemical waste properly.
Never mix chemicals in sink drains. Sinks are
to be used only for water and those solutions
designated by the instructor. Solid
chemicals, metals, matches, filter paper, and
all other insoluble materials are to be
disposed of in the proper waste containers,
not in the sink. Check the label of all waste
containers twice before adding your
chemical waste to the container.
14. Labels and equipment instructions must
be read carefully before use. Set up and use
the prescribed apparatus as directed in the
laboratory instructions or by your instructor.
15. Keep hands away from face, eyes, mouth
and body while using chemicals or preserved
specimens. Wash your hands with soap and
water after performing all experiments.
Clean all work surfaces and apparatus at the
end of the experiment. Return all equipment
clean and in working order to the proper

monitored at all times. You will be assigned a
laboratory station at which to work. Do not
wander around the room, distract other
students, or interfere with the laboratory
experiments of others.
17. Students are never permitted in the
science storage rooms or preparation areas
unless given specific permission by their
18. Know what to do if there is a fire drill
during a laboratory activity; containers must
be closed and any electrical equipment

instruments, always carry with tips and
points pointing down and away. Always cut
away from your body. Never try to catch
falling sharp instruments. Grasp sharp
instruments only by the handles.
20. If you have a medical condition (e.g.,
allergies, pregnancy, etc.), check with your
physician prior to working in lab. CLOTHING 21. Any time chemicals, heat, or
glassware are used, students will wear
laboratory goggles. There will be no
exceptions to this rule!
22. Dress properly during a laboratory
activity. Long hair, dangling jewelry, and
loose or baggy clothing are a hazard in the
laboratory. Long hair must be tied back and
dangling jewelry and loose or baggy clothing

cover the foot. No sandals allowed. STUDENT SAFETY ACKNOWLEDGEMENT 23. Lab aprons have been provided for your
use and should be worn during laboratory
activities. ACCIDENTS AND INJURIES 24. Report any accident (spill, breakage,
etc.) or injury (cut, burn, etc.) to the
instructor immediately, no matter how trivial
it may appear.
25. If you or your lab partner are hurt,

acknowledgement. I realize that I must obey
these rules to ensure my own safety, and
that of my fellow students and instructors. I
will cooperate to the fullest extent with my
instructor and fellow students to maintain a
safe lab environment. I will also closely

any violation of this safety
acknowledgement that results in unsafe
conduct in the laboratory or misbehavior on STUDENT SAFETY ACKNOWLEDGEMENT
my part, may result in being removed from

Student Signature ___
Dear Parent or Guardian:
I feel that you should be informed regarding
the school’s effort to create and maintain a
safe science classroom/ laboratory
environment. With the cooperation of the
instructors, parents, and students, a safety
instruction program can eliminate, prevent,
and correct possible hazards. You should be
aware of the safety instructions your
son/daughter will receive before engaging in
any laboratory work. Please read the list of
safety rules above. No student will be
permitted to perform laboratory activities
unless this acknowledgement is signed by
both the student and parent/guardian and is
on file with the teacher. Your signature on
this acknowledgement indicates that you
have read this Student Safety
Acknowledgement, are aware of the
measures taken to ensure the safety of your
son/daughter in the science laboratory, and
will instruct your son/daughter to uphold
his/her agreement to follow these rules and
procedures in the laboratory.
