Purpose
Science is a hands-on laboratory class. You will be doing many laboratory activities
that 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 agreement. These rules must be followed at all times. A copy of the agreement
is provided. This agreement must be signed by both you and a parent or guardian
before you can participate in the laboratory. The signed second page should then
be turned into your science teacher.
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, etc.) should
be stored in the classroom area.
- Keep aisles clear. Push your chair under
the desk when not in use.
- Know the locations 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 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.
- 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 rooms 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 should
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 from the eyewash station or safety shower for at least 20 minutes.
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.
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 glass 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 cords, 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 insulating 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.
