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 contract.
These rules must be followed at all times.
Two copies of the contract 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 science notebook as a constant
reminder of the safety 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
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 beverages.

by the instructor. Never do anything
in the laboratory that is not called for
in the laboratory procedures or by your
instructor. Carefully follow all instructions,
both written and oral. Unauthorized
experiments are prohibited.

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

the fume hood when working with volatile
substances or poisonous vapors. Never
place your head into the fume hood.
13. Be alert and proceed with caution at
all times in the laboratory. Notify the
instructor immediately of any unsafe
conditions you observe.
14. 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

be read carefully before use. Set up and
use the prescribed apparatus as directed
in the laboratory instructions or by your

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 storage area.
17. Experiments must be personally 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.
18. Students are never permitted in the
science storage rooms or preparation
areas unless given specific permission by
19. Know what to do if there is a fire drill
during a laboratory period; containers
must be closed, gas valves turned off,
fume hoods turned off, and any electrical
equipment turned off.
20. Handle all living organisms used in a
laboratory activity in a humane manner.
Preserved biological materials are to
be treated with respect and disposed of

34. Never use mouth suction to fill a pipet. Use a rubber bulb or pipet pump.
35. When transferring reagents from one container to another, hold the containers away from your body.
36. Acids must be handled with extreme care. You will be shown the proper method for diluting strong acids. Always add acid to water, swirl or stir the solution and be careful of the heat produced, particularly with sulfuric acid.
37. Handle flammable hazardous liquids over a pan to contain spills. Never dispense flammable liquids anywhere near an open flame or source of heat.
38. Never remove chemicals or other materials from the laboratory area.
39. Take great care when transporting acids and other chemicals from one part of the laboratory to another. Hold them securely and walk carefully.
40. Carry glass tubing, especially long pieces, in a vertical position to minimize the likelihood of breakage and injury.
41. Never handle broken glass with your bare hands. Use a brush and dustpan to clean up broken glass. Place broken or waste glassware in the designated glass disposal container.
42. Inserting and removing glass tubing from rubber stoppers can be dangerous. Always lubricate glassware (tubing, thistle tubes, thermometers, etc.) before attempting to insert it in a stopper. Always protect your hands with towels or cotton gloves when inserting glass tubing into, or removing it from, a rubber stopper. If a piece of glassware becomes “frozen” in a stopper, take it to your instructor for removal.
43. Fill wash bottles only with distilled water and use only as intended, e.g., rinsing glassware and equipment, or adding water to a container.
44. When removing an electrical plug from its socket, grasp the plug, not the electrical cord. Hands must be completely dry before touching an electrical switch, plug, or outlet.
45. Examine glassware before each use. Never use chipped or cracked glassware. Never use dirty glassware.
46. Report damaged electrical equipment immediately. Look for things such as frayed cords, exposed wires, and loose connections. Do not use damaged electrical equipment.
47. If you do not understand how to use a piece of equipment, ask the instructor for help.
48. Do not immerse hot glassware in cold water; it may shatter.
49. Exercise extreme caution when using a gas burner. Take care that hair, clothing and hands are a safe distance from the flame at all times. Do not put any substance into the flame unless specifically instructed to do so. Never reach over an exposed flame. Light gas (or alcohol) burners only as instructed by the teacher.
50. Never leave a lit burner unattended. Never leave anything that is being heated or is visibly reacting unattended. Always turn the burner or hot plate off when not in use.
51. You will be instructed in the proper method of heating and boiling liquids in test tubes. Do not point the open end of a test tube being heated at yourself or anyone else.
52. Heated metals and glass remain very hot for a long time. They should be set aside to cool and picked up with caution. Use tongs or heat-protective gloves if necessary.
53. Never look into a container that is being heated.
54. Do not place hot apparatus directly on the laboratory desk. Always use an insulating pad. Allow plenty of time for hot apparatus to cool before touching it.
55. When bending glass, allow time for the glass to cool before further handling. Hot and cold glass have the same visual appearance. Determine if an object is hot by bringing the back of your hand close to it prior to grasping it.
56. Do you wear contact lenses?
57. Are you color blind?
58. Do you have allergies?
If so, list specific allergies___________
