SUBJECT: Asbestos--Notice to Employees
(Connelly Act, AB 3713)
State law requires notification to all UCSD personnel of the
presence of asbestos in certain building materials used in the
construction of University buildings.
Environment, Health and Safety has conducted an extensive survey
to identify those areas at UCSD where asbestos-containing
building materials exist. Updated copies of this survey will be
maintained at the following locations:
All Libraries, public service desks
EH&S, TPCS 450
Physical Plant Services, Campus Services Complex
Facilities Design and Construction, TPC 470
Medical Center, Plant Services
Medical Center, Facilities Management
Almost all buildings at UCSD, with the exception of those built
in the past few years, contain non-friable asbestos materials in
public access areas. These materials include vinyl asbestos floor
tiles and/or linoleum sheet flooring as well as the mastic used
to secure them. In addition, some laboratory and machine shop
areas have benches and/or fume hoods constructed of transite
and/or colorlith. The asbestos in these materials is bonded with
vinyl, epoxy, cement or other materials and under normal
conditions does not pose any danger. If the material is cracked,
drilled, sanded, or otherwise disturbed, however, it could result
in the release of asbestos fibers into the air which could present
a health risk. Such work should only be done by trained personnel
using proper personal protection and containment equipment.
Some other areas contain sprayed-on acoustical material or
ceiling tiles containing asbestos. These materials are somewhat
friable, but do not present a problem if they are not disturbed.
Only trained workers with the proper equipment should perform
work that would have the potential to disturb such materials.
Some of the fire doors used in stairwell smoke towers, and the
entrances to mechanical rooms and cores in the larger buildings
also contain asbestos. These doors are usually wooden and have a
metal label on the inside edge or top identifying them as having
a type "B" fire rating or a rating of one hour or greater.
Many of the larger buildings have asbestos materials in areas of
restricted public access such as mechanical rooms and cores.
These materials include insulation on boilers, heat exchangers,
and some hot and cold water plus steam supply lines. Asbestos
was not used in air system ductwork. In a few instances,
asbestos insulated pipes are in public access areas. As long as
the outer canvas cover or metal sheathing on the pipes is intact,
the insulation presents no health problem. If the protective
covering is disturbed, call the Service Referral Desk (x42930)
and report the problem.
Please disseminate this information to all new employees in your
respective departments. The data base for asbestos is
continually updated as asbestos-containing building materials are
either removed or appropriately sealed.
If you have any questions, or would like more information about
asbestos, please contact the Asbestos Control Coordinator, Denise
Devall-Hall in the EH&S Office at x46748.
