The MSDS for every chemical in your lab
must be available to you. We have them
available in paper form, but the quickest and
easiest way to access MSDS is via the
Internet. A computer is available in the
stockroom office specifically for this purpose.
Material Safety Data Sheets (MSDS)
for any chemical give information
regarding hazards, reactivity, and
disposal. MSDS are available in hard
copy upon request, or electronically
from the following web-sites:
www.hazard.com
www.fisherSci.com
www.sigmaaldrich.com


“A student using research to meet the ACS
certification requirements must prepare a
well-written, comprehensive, and welldocumented research report including safety
presentations.”
Address MSDS safety information regarding
handling and disposal; address safety issues
particular to your research project.
Safety Equipment
Your eyes are important.
Please wear safety glasses!

When using gloves, make sure that the
composition of the glove will not allow the
chemicals I am using to penetrate the glove.
Latex gloves work well for aqueous solutions
and pathogens, but the blue nitrile gloves
have better resistance to organic solvents.
CAUTION
For the safe operation of this
safety shower and eyewash
station, please remove any
electronics from the vicinity
and do not store anything
below them.
The main function of a
fume hood is to exhaust
gases that are generated
in the hood to the outside.
Make sure the exhaust blower is
operating.
Do not put your face inside!
Minimize storage of chemicals.
Close sash when not in use.
Clean spills immediately.
Work with the sash at the proper
operating level.
Use emergency purge if needed.
"Picture a pasture open to all. It is to be expected that
each herdsman will try to keep as many cattle as
possible on the commons.... As a rational being, each
herdsman seeks to maximize his gain. Explicitly or
implicitly, more or less consciously, he asks, 'What is
the utility to me of adding one more animal to my
herd?'"
The Tragedy of the Commons, Garrett Hardin, Science,
162(1968):1243-1248.
There is a new system for borrowing chemicals:
If you borrow a stock chemical (not mixed solutions), you must
fill out a borrow card with the following information and place
it on the shelf in place of the borrowed chemical:
- Chemical Name
-Your Name
-Your Professor’s Name
- Room in which the chemical will be used
**Borrow cards are NOT necessary for solutions unless it is a
stock bottle.
THE STOCKROOM IS A
RESTRICTED AREA.
DO NOT OPEN THE DOOR TO ANYONE
OTHER THAN UCA PERSONNEL AND
APPROVED STUDENTS.
IF YOU ARE UNSURE, CONTACT THE
MAIN CHEMISTRY DEPARTMENTAL
OFFICE BEFORE ALLOWING ACCESS.

Waste containers must be labeled with the
following:
 Name of waste (solute & solvent)
 Estimated amount of waste
 Estimated concentration of solute(s)
 Experiment in which the waste was generated (if
applicable)
Corrosives
Examples: thionyl chloride, bromine, sulfuryl chloride,
benzoyl chloride, triethyl amine, trihydrofluoride, benzene
sulfuryl chloride
Oxidizing Inorganic Acids
Examples: sulfuric, nitric, chromic, and perchloric acids
Organic acids &
Non-oxidizing Inorganic Acids
Examples: acetic, butyric, and formic acids;
hydrochloric, hydrofluoric, hydrobromic, hydroiodic,
and phosphoric acids

Inorganic chemicals and solutions are
organized alphabetically by chemical name,
NOT chemical formula.
 Eg. NaCl would be filed with S, for sodium
chloride, not N.


There are areas in the stockroom set aside for
specific types of waste (see next slide).
To store waste containers until the following
year, ensure that waste containers:
 Are labeled appropriately
 Are tightly sealed

If the waste chemical should be kept cool,
please store with the refrigerator waste.

Incoming chemicals must be labeled with the
following:
 Date received
 NFPA hazard diamond (if not labeled by
company)

These metal trash cans are for empty glass
chemical containers. “Empty” is defined as
less than 2.5 cm of residue or less than 3% of
the total weight. Depending on the chemical,
use water or an organic solvent to rinse the
container before placing in a metal trash can.
If the chemical is hazardous (toxic, corrosive,
reactive, or highly flammable), collect the
rinse and place in a labeled chemical waste
container.

Take care when transporting chemicals and
use rubber carriers for glass, 4 L containers.

If elemental mercury is spilled, notify your
research advisor immediately for safe
cleanup and disposal.

Keep ferromagnetic objects away from
strong magnetic fields, such as near our
Nuclear Magnetic Resonance (NMR)
instrument.

Check the label on each chemical container
before using it to make sure it contains what
is needed for the experiment. Only take as
much of the chemical as is needed for the
experiment at hand.


If a small fire is confined to a container, I will
allow it to burn until the fuel has been
exhausted or cover the container. If there is a
small fire that is not in a container, use a fire
extinguisher. If there is a large, open fire,
leave the area immediately and notify others.
If clothing is on fire, Stop, Drop, and Roll (not
run!).
New fire blanket instructions posted.

Do not use an open flame in the vicinity of
flammable organic solvents.

Do not store oxidizers near flammables with
an NFPA rating of 2 or above.

Check for leaks in gas cylinder connections,
make sure that gas cylinders are strapped to
the wall, and used a cylinder cart for
transporting gas cylinders (with caps).


Recognize that at the temperature of liquid
nitrogen (77 K), oxygen in the atmosphere
condenses and might react with chemicals in
the container or liquid nitrogen trap to form a
potentially explosive mixture.
Do not use liquid nitrogen in a small, confined
space since the nitrogen can displace oxygen
in the air and result in asphyxiation.
