Student Safety Contract
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.
- Conduct yourself in a responsible manner at all times in the laboratory.
- Follow all written and verbal instructions carefully. If you do not understand a
direction or part of a procedure, ask the instructor before proceeding.
- Never work alone. No student may work in the laboratory without an instructor present.
- 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.
- Do not eat food, drink beverages, or chew gum in the laboratory. Do not use laboratory
glassware as containers for food or beverages.
- Perform only those experiments authorized 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
- 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.

substances or poisonous vapors. Never place your head into the fume hood.
- Be alert and proceed with caution at all times in the laboratory. Notify the instructor
immediately of any unsafe conditions you observe.
- 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.
- 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.
- Keep hand 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.
- 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.
- Students are never permitted in the science storage room or preparation areas unless
given specific permission by their instructor.
- 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
- 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 properly.
- 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.
- Any time chemicals, heat, or glassware are used, students will wear laboratory goggles.
There will be no exceptions to this rule!
- Contact lenses should not be worn in the laboratory unless you have permission from your
- 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 must be secured. Shoes must completely cover the foot.
No sandals allowed.
- Lab aprons have been provided for your use and must be worn during laboratory
Accidents and Injuries
- Report any accident (spill, breakage, etc.) or injury (cut, burn, etc.) to the
instructor immediately, no matter how trivial it may appear.
- If you or your lab partner are hurt, immediately yell out "Code one, Code one"
to get the instructor's attention.
- If a chemical should splash in your eye(s) or on your skin, immediately flush with
running water for at least 20 minutes. Notify the instructor immediately.
- When mercury thermometers are broken, mercury must not be touched. Notify the instructor
- 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.
- Check the label on chemical bottles twice before removing any of the contents. Take only
as much chemical as you need.
- Never return unused chemicals to their original containers.
- Never use mouth suction to fill a pipet. Use a rubber bulb or pipet pump.
- When transferring reagents from one container to another, hold the containers away from
- 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.
- Handle flammable hazardous liquids over a pan to contain spills. Never dispense
flammable liquids anywhere near an open flame or source of heat.
- Never remove chemicals or other materials from the laboratory area.
- Take great care when transferring acids and other chemicals from one part of the
laboratory to another. Hold them securely and walk carefully. Be observant.
Handling Glassware and Equipment
- Carry glass tubing, especially long pieces, in a vertical position to minimize the
likelihood of breakage and injury.
- 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 disposal container.
- 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.
- Fill wash bottles only with distilled water and use only as intended, e.g., rinsing
glassware and equipment, or adding water to a container.
- 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.
- Examine glassware before each use. Never use chipped or cracked glassware. Never use
- Report damaged electrical equipment immediately. Look for things such as frayed cores,
exposed wires, and loose connections. Do not use damaged electrical equipment.
- If you do not understand how to use a piece of equipment, ask the instructor for help.
- Do not immerse hot glassware in cold water, it may shatter.
- 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.
- 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.
- 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.
- 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.
- Never look into a container that is being heated.
- Do not place hot apparatus directly on the laboratory desk. Always use an insulting pad.
Allow plenty of time for hot apparatus to cool before touching it.
- 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.
