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. The contract are must be signed by both you and a parent or guardian before you can participate in the laboratory. GENERAL 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 or drink beverages in the laboratory. Do not use laboratory glassware as containers for food or
beverages. 6.
Perform
only those experiments authorized. 7.
Be
prepared for your work in the laboratory.
Read all procedures thoroughly before starting the laboratory experiment. 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 to the work area. Other materials (books, purses, backpacks,
etc.) should be stored under your chairs or in the classroom area. 10.
Keep
aisles clear. Push your chair under
the desk or table. 11.
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. 12.
Be
alert and proceed with caution at all times in the laboratory. Notify the instructor immediately of any
unsafe conditions you observe. |
13.
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. 14.
Labels
and equipment instructions must be read carefully before use. Set up and use prescribed apparatus as
directed in the laboratory instructions or by your instructor. 15.
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 all work surfaces and apparatus at the end of the
experiment. Return all equipment
clean and in working order to the proper storage area. 16.
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. 17.
Students
are never permitted in the science storage areas or preparation areas unless
given permission by the instructor. 18.
Know
what to do if there is a fire drill during a laboratory period; containers
must be closed, gas valves turned off, and any electrical equipment turned
off. 19.
Handle all living
organisms used in a laboratory activity in a humane manner. 20.
When using knives and
other sharp instruments, always carry with the 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. 21.
If you have a medical
condition (e.g., allergies, pregnancy, etc.), check with your physician prior
to working in lab. CLOTHING
22.
Any
time chemicals, heat, or glassware are used, students will wear laboratory
goggles. There will be no exception
to this rule. 23.
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. |
24.
Lab
aprons have been provided for your use and should be worn during lab
activities to prevent stains on your clothing. ACIDENTS AND
INJURIES
25.
Report
any accident (spill, breakage, etc.) or injury (cut, burn, etc.) to the
instructor immediately, not matter how trivial it may appear. 26.
If
you or your lab partner are hurt, immediately yell out “Code one, Code one”
to get the instructor’s attention. 27.
If
chemical splashes 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. 28.
When
mercury thermometers are broken, mercury must not be touched. Notify the instructor immediately. HANDLING CHEMICALS
29.
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. 30.
Check
the label on chemical bottles twice before removing any of the contents. Take only as much chemical as you need. 31.
Never
return unused chemicals to their original containers. 32.
Never
use mouth suction to fill a pipet.
Use a rubber bulb or pipet pump. 33.
When
transferring reagents from one container to another, hold the containers away
from your body. 34.
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. 35.
Handle
flammable hazardous liquids over a pan to contain spills. Never dispense
flammable liquids anywhere near an open flame or source of heat. 36.
Never
remove chemicals or other materials from the laboratory area. 37.
Take
great care when transporting acids and other chemicals from one part of the
laboratory to another. Hold them
securely and walk carefully. HANDLING GLASSWARE AND EQUIPMENT 38.
Carry
glass tubing, especially long pieces, in t vertical position to minimize the
likelihood of breakage and injury. |
|
39.
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. 40.
Inserting
and removing lass 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. 41.
Examine
glassware before each use. Never use
chipped or cracked glassware. Never
use dirty glassware. 42.
Do
not immerse hot glassware in cold water; it may shatter. 43.
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. 44.
Report
damaged electrical equipment immediately.
Look for things such as frayed cords, exposed wires, and loose
connections. Do not use damaged
electrical equipment. 45.
If
you do not understand how to use a piece of equipment, ask the instructor for
help. HEATING SUBSTANCES
46.
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 burners only as instructed by
the teacher. 47.
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. 48.
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. 49.
Heated
metals and lass 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. 50.
Never
look into a container that is being heated. 51.
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. |
52.
When
bending glass, allow time for the glass to cool before further handling. Hot and cold glass has the same visual
appearance. Determine if an object is
hot by bringing the back of your hand close to it prior to grasping it. QUESTIONS
