DEPARTMENT OF CHEMISTRY & PHYSICS
CHEMISTRY LABORATORY RULES AND REGULATIONS
Please read the following carefully and keep this document with you at all times when
in the laboratory. Your lab instructor will go over these rules and regulations with you
at the beginning of the lab course and it is up to you to make sure that you fully
understand all that follows at that time. Remember: these rules are for your own
protection and if followed by all will result in a safe laboratory environment. A copy of
this document can be found in the public folder (and web-site if appropriate) for each lab
course and one is posted in each lab. IF IN DOUBT ABOUT ANYTHING ASK. THE LABORATORY IS
NO PLACE TO MAKE ASSUMPTIONS!
1. EYE PROTECTION
Since eyes are especially vulnerable in the chemistry laboratory, approved safety
goggles MUST BE WORN AT ALL TIMES. Failure to do so will result in IMMEDIATE
EXPULSION and an unexcused absence for that experiment.
Eye injuries, whether chemical or mechanical, must always be considered serious. The
best procedure in case of chemical injury to the eye is immediate and prolonged (15 - 20 minutes)
flushing with water. Eyes must be forced open to be washed well. Make sure you know the
locations of the eyewash stations in the lab.
2. LEG AND FEET PROTECTION
Bare feet or any type of open shoe or sandal can not be worn into the chemistry
laboratory. Likewise, short pants and skirts are also not permitted. It is recommended
that you don't wear your best clothes to lab.
3. FIRST AID
In case of minor cuts or burns, report them immediately to your instructor or the
laboratory manager. Minor first-aid treatment can be given within the building.
4. SERIOUS INJURY
If a person is seriously injured, do not attempt to move the person. Notify your
instructor immediately. Stay with the person until help arrives.
5. SMOKING, EATING OR DRINKING
Smoking, eating or drinking are not allowed in the teaching laboratories or the stockroom.
6. CHEMICAL FUMES
Exercise great care in noting the odors of fumes and avoid breathing fumes of any kind.
7. CHEMICAL SPILLS AND BENCH TIDINESS
Small spills should be cleaned up using the appropriate method. If in doubt or for
larger spills, contact your instructor or the laboratory manager for instructions. You are
responsible for keeping your bench tidy at all times. Do not use the analytical balances
for weighing out NaOH and KOH. Use the top-loading balances for this purpose. It is your
responsibility to keep all balances clean at all times. Failure to so will result in a
lowering of everyone's lab grade by 5% for the first offense, 10% for the second and so
on. All items not required to run an experiment (e.g. book bags, coats, etc.) must not be
placed in the aisles or on the bench tops. In P-274 use the adjacent student
lounge. In P-210 use the area next to the windows.
8. RUNNING EXPERIMENTS
Do not change the experimental procedure in anyway unless instructed to by the
instructor. Always know the chemicals you are working with and what to do in case of an
accident or spillage. You have the right of access to the Material Data Safety (MSD) sheet
for any chemical you are using. Please contact the lab manager for access to the MSD
sheets. Never take chemicals out of the lab. Keep transportation of chemicals to a minimum
in the lab. Always transport chemicals in an appropriate container. If a chemical
container is empty and needs refilling take the empty container to the stockroom for
refilling. You are not allowed to take chemicals out of the stockroom unless the lab
manager or a designated work-study student gives them to you. Put all ring stands and
supports back where you found them. Make sure they are put away properly and that they do
not block the aisles. You are not allowed to work alone in a lab. Make sure there is
always at least one other person in the lab with you.
9. LAB HOURS
You are not allowed to work in the lab outside of times regularly scheduled for your
lab section unless given permission by the instructor involved. Working in the lab after
hours is expressly forbidden except for students enrolled in senior research and upper
division courses. Such students must have the permission of their supervisor for each
occasion and are not allowed to work alone under any circumstances. Lab work is not
allowed during times the College is officially closed.
Familiarize yourself with the location and proper use of the fire extinguishers. Should
a fire alarm sound while you are working in the lab, turn off any heat source and leave
the building by the nearest exit. Try to remain together as a group and await further
THE MOST DISTRESSING AND SERIOUS LABORATORY ACCIDENTS ARE CAUSED BY
CLOTHING CATCHING FIRE.
STOP - DROP - ROLL
When a person's clothing catches fire, the first thing to do is to throw that person to
the floor and roll them so as to smother the flames quickly. Never let the person remain
in a standing position even if you must trip or knock them down; this procedure will
prevent injury to the respiratory passages and the eyes by the flames which would
naturally rise and envelop the head.
STOP - DROP - ROLL
Never turn a fire extinguisher of any type on a person whose clothing is on fire. Eye
injuries may result from a dry-chemical type and frostbite from the "snow" of
the carbon dioxide type. Do not use the safety shower to extinguish a person on fire.
STOP - DROP - ROLL
11. THE SAFETY SHOWER IS MAINLY INTENDED TO BE USED IN CASES WHERE CORROSIVE
CHEMICALS ARE SPILLED OR SPLASHED OVER A LARGE BODY AREA AND MUST BE WASHED OFF RAPIDLY.
DO NOT attempt to use the shower to extinguish clothing on fire. Clothing
soaked with strong acid or base should be removed. This is no time for modesty. Plenty of
running water is the best first-aid treatment for all acid and base accidents. Rapid and
immediate treatment is essential. Use lots of water; a little water or a damp cloth may be
worse than no water at all because of the heating effect.
THROW AWAY CRACKED OR CHIPPED GLASSWARE IMMEDIATELY and obtain replacements from
the stockroom. Broken glassware must be placed in the special trashcan labeled BROKEN
GLASS ONLY. Your lab fee for this course only covers $30.00 worth of broken glassware.
It is therefore necessary for the department to charge you replacement costs for broken
glassware above this value.
13. USED CHEMICALS
If no disposal procedures are given with a particular experiment ask your instructor or
the laboratory manager about the disposal of used chemicals. Most chemicals cannot be
poured down the sink. NEVER DISPOSE OF A CHEMICAL WITHOUT CHECKING WITH YOUR
Safety Acceptance Form
