Student Safety Contract
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 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.
General Guidelines
- 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 prohibited.
- 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.
- 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, coats,
etc.) should be stored in the classroom area.
- Keep aisles clear. Push your chair under the desk when not in use.
- Know the location and operating procedures of all safety equipment
including the first aid kit, eyewash station, safety shower, fire extinguisher,
and fire blanket. Know where the fire alarm and the exits are located.
- Always work in a well-ventilated area. Use the fume hood when working with
volatile 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 off.
- 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.
Clothing
- 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 instructor.
- 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 activities.
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 immediately.
Handling Chemicals
- 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 your body.
- 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 dirty glassware.
- 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.
Heating Substances
- 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.
