Student Safety Contract for Mr. Wigger’s
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 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
beverages.

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.
7. Be prepared for your work in the laboratory. Read all
procedures thoroughly before entering the laboratory. Never fool around in the
laboratory. Horseplay, practical jokes, and pranks are dangerous and
prohibited.

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.
12. 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.
13. 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 (with detergent), rinse, and wipe dry
all work surfaces (including the sink) and apparatus at the end of the
experiment. Return all equipment clean and in working order to the proper
storage area.
14. 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.
15. Students are never permitted in the science storage rooms
or preparation areas unless given specific permission by their instructor.
16. 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.
17. Handle all living organisms used in a laboratory
activity in a humane manner. Preserved biological materials are to be 20.
When using knives and other sharp 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.
CLOTHING
18. Any time chemicals, heat, or glassware are used, students will wear
laboratory goggles. There will be no exceptions to this rule!

HANDLING CHEMICALS
26. All chemicals in the laboratory are to be considered dangerous. Do
not touch, taste, or smell any chemicals unless specifically instructed to do
so. The proper technique for smelling chemical fumes will be demonstrated to
you.
27. Check the
label on chemical bottles twice before removing any of the con-tents. Take only
as much chemical as you need.
28. Never
return unused chemicals to their original containers.
29. Never use
mouth suction to fill a pipet. Use a rubber bulb or pipet pump.
30. When transferring reagents from one container to another,
hold the containers away from your body.
31. 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.
32. Handle flammable hazardous liquids over a pan to contain
spills. Never dispense flammable liquids anywhere near an open flame or source
of heat.
33. Never remove chemicals or other materials from the
laboratory area.
34. Take great care when transferring acids and other
chemicals from one part of the laboratory to another. Hold them securely and
walk carefully. HANDLING GLASSWARE AND EQUIPMENT
35. Carry glass tubing, especially long pieces, in a vertical
position to minimize the likelihood of breakage and injury.
36. 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.
37. 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.
38. Fill wash bottles only with distilled water and use only
as intended, e.g., rinsing glassware and equipment, or adding water to a
container.
39. 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.
40. Examine glassware before each use. Never use chipped or
cracked glassware. Never use dirty glassware.
41. Report damaged electrical equipment immediately. Look for
things such as frayed cords, exposed wires, and loose connections. Do not use
damaged electrical equipment.
42. If you do not understand how to use a piece of equipment,
ask the instructor for help.
43. Do not immerse hot glassware in cold water; it may
shatter.
HEATING
SUBSTANCES
44. 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.
45. 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.
46. 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.
47. 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.
48. Never look into a container that is being heated.
49. 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.
50. 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 bock of your hand close to it
prior to grasping it.
