Physics Laboratory Safety
Remember:
The equipment and apparatus you will use involve various
safety hazards, just as they do for working physicists. You must be aware of
these hazards. Your teacher will guide you· in properly using the equipment and
carrying out the experiments, but you must also take responsibility for your
part in this process. With the active involvement of you and your teacher,
these risks can be minimized so that working in the physics laboratory can be a
safe, enjoyable process of discovery.
These safety rules apply in the lab
1.
Always have your safety goggles and wear them
whenever using tools or equipment, or whenever the instructor tells you to.
2.
Personal apparel should be appropriate for
laboratory work. On lab days avoid wearing long necklaces, dangling bracelets,
bulky jewelry, and bulky or loose-fitting clothing. Long hair should be tied
back. Loose, dangling items may get caught in moving parts, accidentally
contact electrical connections, or interfere with the investigation in a
potentially hazardous manner. In addition, chemical fumes may react with some
jewelry, such as pearls, and ruin them. Cotton clothing is preferable to wool,
nylon, or polyester. Wear shoes that will protect your feet from chemical
spills and falling objects-open-toed shoes or sandals, and shoes with woven
leather straps are not allowed in the laboratory.
3.
NEVER work alone in the laboratory. Work in the
lab only while under the supervision of your instructor. Do not leave equipment
unattended while it is in operation.
4.
Only books and notebooks needed for the
experiment should be in the lab. One book bag may be kept by your seat. Use the
atrium/mud room to store other stuff, especially skateboards and other items
that could get in the way or cause an accident.
5.
Listen! Your instructor will review applicable
safety precautions before the lab. If you are not sure of something, ask your instructor
about it. Turn cell phone ringers off. Always heed safety symbols and cautions
written in the experimental investigations and handouts, posted in the room,
and given verbally by your instructor. They are provided for your safety.
6.
Know the proper fire drill procedures and the
location of fire exits and emergency equipment. Make sure you know the
procedures to follow in case of a fire or an emergency.
7.
If your clothing catches on fire, do not run; WALK
to one of the two showers in the building, stand under it, and turn it on. Call
to your instructor while you do this.
8.
Report all accidents to the instructor immediately,
no matter how minor. In addition, if you get a headache, feel sick to your
stomach, or feel dizzy, tell your instructor immediately.
9.
Report all spills to your instructor immediately.
Call your instructor rather than trying to clean up a spill yourself. Your instructor
will tell you if it is safe for you to clean up the spill; if not, your instructor
will know how the spill should be cleaned up safely.
10. Student-designed
investigations, such as the work for the final project, must be approved by the
teacher before being attempted by the student.
11. DO
NOT perform unauthorized experiments or use materials and equipment in a manner
for which they were not intended. Use only materials and equipment listed in
the activity equipment list or authorized by your teacher. Steps in a procedure
should only be performed as described in the textbook or lab manual or approved
by your teacher.
12. Stay
alert in the lab, and proceed with caution. Be aware of others near you or your
equipment when you are performing an experiment. If you are not sure of how to
proceed, ask.
13. Horseplay
in the lab is very dangerous. Laboratory equipment and apparatus are not toys;
never play in the lab or use lab time or equipment for anything other than
their intended purpose.
14. Food,
beverages, and chewing gum are NEVER permitted in the lab room during lab hours.
15. Exercise
caution when working with electrical equipment. Inspect all such equipment
before use or get the instructor to inspect it for you. Do not use electrical
equipment with frayed or twisted wires. Be sure your hands are dry before using
electrical equipment. Do not let electrical cords dangle from work stations;
dangling cords can cause electrical shocks and other injuries.
16. Keep
work areas and apparatus clean and neat. Always dean up any clutter made during
lab work, rearrange apparatus in an orderly manner, and report any damaged or
missing items. Return all equipment and tools to where you found them at the
end of the lesson or when switching to a different activity.
17. Always
wash your hands with soap and water at the conclusion of each investigation.
