A college chemistry lab is a relatively safe environment when
students follow simple safety rules, know what they are doing in
their experiments, and pay attention to specific hazards of each
chemical and procedure. You are responsible for laboratory safety. You
will be handling glassware, fire, and chemicals which may be flammable,
corrosive, reactive, and/or otherwise toxic. The most frightening
aspect of this is that your classmates (some of whom may not have
read the lab manual nor listened very well during the prelab discussion)
are handling the same dangerous materials. Each student is responsible
for following all safety rules. Safety is the most important aspect of Chemistry 152L. Please
read the safety rules on your Check-In sheet. Violation of any safety rule may result in dismissal and a grade of zero on the lab.
You must
be present for each "pre-lab" safety and orientation discussion.
If you arrive late and miss it, please see me before you begin working on your
experiment. |
Some general rules are outlined below. Others will be distributed
with your check-in materials. Still more rules will stated by your
instructor for specific labs during the pre-lab discussion. It is
very important that you arrive on time for each lab so that you
can hear the pre-lab discussion and be aware of the specific safety
hazards involved for each experiment.
Safety goggles (ANSI-Z87 certified splash proof goggles, not glasses with side
shields).
- Required whenever anyone in the room is working
with chemicals or lab equipment.
- If you need a break from goggles, leave the room for a
while.
- Students violating Rule 1.a. will lose lab points and/or
be dismissed from lab.
- Proper clothing.
- Old clothes. (Note: strong acids, bases, and some other
chemicals will dissolve and/or stain most fabrics.)
- Shoes with tops, i.e., close-toed shoes (to protect against falling objects or
chemicals).
- Experiments.
- Conduct experiments strictly as outlined in the lab manual,
unless modified by instructor.
- No unauthorized experiments.
- Never use laboratory chemicals or equipment without an
instructor present.
- Dispose of chemicals in the proper hazardous waste container. If you're not sure, please ask!
- LISTEN and PAY ATTENTION during pre-lab discussion. This
is when I go over the chemical concepts and experimental
procedure, and point out some of the experiment-specific
hazards and important precautions. Do
not be late for lab! (This
is a safety policy, in addition to being a District
rule.)
- List of NO's.
- No fooling around with chemicals or equipment.
- No messy bench tops. Clean up all spills immediately.
- No smoking.
- No eating.
- List of KNOW's.
- Know hazards of each particular chemical. (see MSDS collection
in the lab or online)
- Know location of all safety equipment, including the exits,
fire extinguishers, eye wash and shower, first aid kit, dustpan
and brush, glassware and hazardous waste disposal locations,
fire blankets, telephone and/or "red" emergency
call box, lab hoods, and the MSDS collection.
- Know when and how to use all safety equipment.
- Know what you're doing in the lab, and why you're doing
it. If you don't know, please ask!
Additional rules will be presented on the first day, and later
for each specific experiment. Violation of any safety rule may result in dismissal from class. If dismissed, you lose credit for the lab.
Please be safe. |
