Safety Office at X6-3661 to make an appointment to bring the chemicals
to the laboratory.
handling hazardous waste other than organic solvent waste:
Waste must be collected and stored in the same or adjacent room
to where it is generated before it is transported to the Chemistry
Hazardous Waste facility. At the present time, Molecular Sciences,
Room 2104 is the first area of the Chemistry Hazardous Waste Facility.
2. Waste containers
must be controlled by the designated person(s) who must know and
control all waste going into the collection container. The person(s)
must also sign the Hazardous Waste Identification Tag or Manifest.
Each research group should assign a responsible person or persons
for this duty.
3. All containers
used for the storage or transport of chemicals must be suitable
for that type of chemical. The containers must be tightly closed
and in good condition, without leakage, rusting, or other defects.
4. All waste
containers must be labeled using the "Hazardous Waste Identification
Tag" or the "Hazardous Waste Manifest". These can be obtained at
the Chemical Safety Office (Young Hall 4204), and from the EH&S
Health and Safety (EH&S) has only 90 days to ship waste off
campus. Since the 90 days begins at the first day of collection
in some cases, it is important to remove full or partially full
waste containers from the laboratory to Mol Sci 2104 frequently.
Waste Identification Tag and Hazardous Waste Manifest
Either a Hazardous
Waste Identification Tag or Hazardous Waste Manifest (identical
except for size) must be filled out for each bottle, jar or container
of hazardous waste. The Tag or Manifest should be secured to the
container at the beginning of collection and a running record of
contents should be listed. Where this is not convenient, the Manifest
should be under or next to the container, and a running total kept.
Hazardous Waste tags and Manifests should be labeled using the following
1. List the
first date on which any waste was placed in the container.
2. List the
Department (Chemistry and Biochemistry).
3. List the

can I find MSDS sheets?
of MSDS sheets are kept in a filing cabinet in the Chemical Safety
Office, room 4204 Young Hall, telephone (20)6-3661. They are filed
alphabetically in cabinets labeled "MSDS ".
Safety Office is open Monday - Friday, 8:00 a.m. to 5:00 p.m. For
after hours entrance, the Faculty master key will open the office
A more convenient
way to obtain MSDS sheets is through the Internet. There is a link
on the Chemistry Home Page to the University of Utah's MSDS database.
Fisher Scientific has a database of MSDS also. The University of California
office of the President, has MSDS's from various manufacturer's,
Are safety glasses or goggles required in the lab?
glasses are required in labs at UCLA. Safety glasses can be obtained
in the Research Storeroom, Young Hall 3056. Employees can
get the first pair of Safety glasses free by ordering them through
Kyra Marsh in the Business Office, telephone X5-3865.
What kind of gloves offer the best protection while working with
of gloves is not as straight-forward as it seems. Certain gloves
are protective against certain solvents, while useless against others.
can be used for total immersion in a solvent while others will withstand
less permeating chemicals in intermittent contact. Various thickness'
have different protective factors. Factors such as flexibility,
cut and tear resistance, and temperature range should be considered.
gloves for protection should become familiar with the various protective
materials from which gloves are made and look at Glove Selection
Charts for applicability. Glove selection charts can be obtained
from the manufacturers of the gloves and from the laboratory supply
catalogues. There are also good references in textbooks, such as
"Fundamentals of Industrial Hygiene", "Prudent Practices in the
Laboratory" and other sources. An important point to remember is
that disposable gloves are not suitable for use with hazardous or
aggressive chemicals. The disposable nitrile gloves carried by the
Research storeroom are suitable for brief or intermittent chemical
exposure to some chemicals. The manufacturer provides a chart of
suitability. If there are questions about suitability of gloves,
please call Bill Peck at X6-3661.
How should I clean up a chemical spill?
FOR LARGE OR
spills involving large quantities of hazardous materials or
highly toxic chemicals, the UCLA Hazardous Materials Team should
be contacted. The number to reach them is 825-5689, or 911 in
an emergency. The Chemical Safety Office should also be notified
at 206-3661. The Haz Mat Team will do the cleanup.
In the event
of a fire emergency or after hours, please call 911.
Procedure for Large or Major Spill
1. Alert people
in the area to evacuate.
2. If spilled
material is flammable, turn off ignition and heat sources if
it is safe to do so.
call the Hazardous Materials Team (825-5689) or activate the
building fire alarm and call 911.
doors to affected area and leave the immediate area.
FOR SMALL OR
MINOR CHEMICAL SPILLS
less toxic chemical spills can be handled by trained personnel
in the department. For the purposes of this policy, a small
spill can be defined as a volume of less than a liter. In many
cases, the use of a respirator will be appropriate. If a respirator
is to be used during a spill cleanup, the chemical to be cleaned
up must have good warning properties. This could be a recognizable
odor perceived at low concentrations, or a visual observation
of fine particulates.
to clean up spills, the laboratory personnel should consult
the MSDS to determine the hazards associated with the chemical.
Laboratory personnel should pay attention to special handling
requirements, spill clean up procedures, and recommended personal
protective equipment indicated on the MSDS. Examples of materials
which can be safely cleaned up by laboratory personnel are the
acids and bases
- most solvents
of low toxicity
spilled from a broken thermometer
personnel must have the proper personal protective equipment
to clean up a spill. Any questions regarding the ability to
safely clean up spills should be addressed to the Chemical Safety
Office at 206-3661 or to the Office of Environment Health and
Safety at 825-5689.
Procedure for small or minor spills
for cleanup can be obtained from the Spill Response Cart, located
in Molecular Sciences, Room 3114. The spill response cart has
a number of supplies on it including brooms, mops, vermiculite,
sand, absorbent pads, spill control pillows, sodium bicarbonate,
and citric acid. In addition, there are yellow hazardous waste
bags for trash and paper generated from the cleanup. There are
additional supplies available in the Emergency Cage (Young Hall,
first floor, near the Receiving area).

How can I obtain a respirator?
planning on using a respirator on a regular basis must receive training
in the proper use, maintenance, storage and fit of the respirator.
This training requirement includes those persons who have purchased
their own respirators, as well as the respirators provided by the
is given in the Department of Chemistry and Biochemistry on an annual
basis. Disposable respirators are provided to participants in the
Respirator Program. It is anticipated that the respirators provided
will be used for emergency use, when cleaning up spills, or when
cleaning out refrigerators or cabinets. Please call the Chemical
Safety Office at phone: 63661 for the scheduled training. Training
can also be provided on an individual basis as needed.
information, refer to the Respiratory Protection Policy of the Department.
How can I update the sign on the laboratory door?
The sign on
the Laboratory door is an NFPA sign and is updated at least yearly,
usually in the Spring. If there are major changes or reasons to
update the sign, speak to the Principal Investigator and he can
request the Chemical Safety Office to update it. Don't attempt to
update it yourself, since that update will not change the database
where the information is stored.
Are there any Safety videos available for viewing?
The Office of
Environment Health and Safety has numerous videos available for
viewing. Please contact them at (82)5-5689. The Chemical Safety Office
has a smaller selection, which are available for checkout.
