mENfirZcancw of asbestos ccniainiijg materials in buhhdjgs
New asbestos regulations require the identification, inspection and labeling of all asbestos containing Tratprials so that the potential for personnel exposure can be determined. The requirement to identify and maintain asbestos in a non-friable condition is a requirement of Texas Operations Safety Standard #45 and should be completed for process areas. There may be areas, however, where this has not been done for buildings (offices, etc.). -
An inspection of buildings must be done to determine the presence or absence of asbestos containing material. Industrial Hygiene Services must be notified if there is visible evidence of deterioration of asbestos materials and/or construction or maintenance activities which would disturb the materials. Industrial Hygiene will determine if there is a need for monitoring. Inspection and notification of IKS must be completed by November 15th. A permanent record of these activities must be maintained by the owner.
In order to assure crrr.1 iance with these requirements, information outlining the procedures for the i-first-;en and inspection of asbestos in buildings is attached. The asbestos task farce will include the'requirements far cperations/maintenance and training programs in the next revision of the Texas Operations Asbestos Handbook.
If you have questions concerning implementation of this program, please call Industrial Hygiene Services at 238-1281.

GUIDELINES FOR IDENTIFICATION OF ASBESTOS CONTAINING MATERIALS IN BUILDINGS
Check building records for evidence of asbestoscontaining surfacing materials, pipe and boiler insulation, or miscellaneous asbestos-containing materials (ACM) .
Locate and document all ACM identified in building records.
Inspect the building for friable materials on Malls or ceilings. Inspection means touching walls and ceilings.
Inspect the building for insulation on pipes and boilers. Inspections means looking at pipes and boilers.
Be persistent. Friable materials may be hidden behind dropped ceilings or partitions.
Collect samples of friable ceiling and wall materials. (Wear an approved respirator during sampling.)
Collect samples of pipe and boiler wrap.
Send samples to Analytical Services, B-1225, (phone 1075) for identification.
Document all findings.
Assess the potential for asbestos fiber release from asbestos-containing materials:
Evidence of deterioration or delamination from the underlying surface (substrate) .
Evidence of physical damage (e.g.. presence of debris).
Evidence of water damage.
Proximity to air plenum or direct airstream.
Visibility, accessibility (to building occupants and maintenance personnel), and degree of activity (air movement, vibration, movement of building occupants).
Notify the Industrial Hygiene Department in writing of any evidence of deterioration of ACM by November 15. 1986.

Conducting the Survev
Begin by reviewing building records to see if Ad was specified at any stage. Although building records are often unreliable, they are a useful starting point. Check the original plans, shop drawings, remodeling records, and work change orders. Appendix A is a list of the most rrumra uses and types of Ad in buildings since 1960. If any of these items appears in the records, assume that asbestos is in the building. Identify Ad mentioned in building records by type: (1) troweled- or sprayed- cn surfacing material, (2) pipe and boiler insulation, or (3) other miscellaneous Ad.
Next, inspect the building for Ad identified in the building records. Determine if the materials are friable and records the findings. They nay he sampled and analyzed to confirm the presence of asbestos. Thoroughly inspect all areas of the building for friable materials and sample them. The specific procedures for inspection and sampling vary depending cn which of the three types of material are involved. The sampler of building natfrr*7^ should wear a respirator to prevent inhalation of fibers.
Procedures for Strayed- or Trcweled-cn Surfacing Materials
Surfacing materials can be friable car ncnfriable. Friable forms axe either very fibrous and fluffy (sometimes like cotton candy) or granular and cementitious. (See Figure 1.) Since friable materials are mere likely than ncnfriable Tnat-^r-i a7 < to release fibers wen disturbed, the first priority is to identify these friable surfacing materials that contain asbestos. The first step is to locate Ad specified in building records and determine it friability. Then, identify all friable surfacing materials in the building and take samples to be analyzed far asbestos.
Surfacing Materials Identified as Ad in Building Records
Begin by locating any acoustical plaster or other surfacing materials
that, according to building records,' contain asbestos. Rub these
materials to see if they craihle or produce a light powder. If so,
consider them friable. (When disturbing material that may contain
asbestos, the inspector should wear protective equipment.) Sample and
analyze these Tnatw-i*'i<; as di
helcv. Record the location and
degree of friability.

Other Surfacina Materials That May Contain Asbestos
Page 2 of 3
Conduct a thorough, building inspection fear friable materials ai vails, ceilings, beans, ducts, and any other surface. Pub the material to see if it is friable. Group any friable material into "homogeneous" areas for further study. A homogeneous area contains friable material that seem by texture and color to be uniform. If materials appearing uniform were installed at different times, designate the two materials as distinct honogeneous areas.
Cnee homogeneous areas of friable materials have been delineated and recorded on floor plans, collect samples of the materials and send them to Analytical Services far analysis.
Record the results of the sampling and analysis program and save the records indefinitely. If no asbestos is found in these materials, no further action is necessary.
Procedures for Pine and Boiler Insulation
Asbestos-containing insulation is found cm equipment containing hot air or liquid - pipes, boilers, tanks, and sometimes ducts. These
insulation materials may be a chalky mixture of magnesia and asbestos, preformed fibrous asbestos wrapping, asbestos fiber felt, corrugated paper, car insulating cement, in most cases, the insulating material is
covered with a protective jacket of cloth, tape, paper, metal or cement. (Insulation with pink or yellow wrap is usually a clear indication of fibrous glass rather than asbestos material. However, pipe elbows and joints will likely contain asbestos.)
Sample the insulation materials fros the damaged or exposed ends or ether parts. Procedures far sampling and analyzing insulation materials are s-imiia-r to these far surfacing materials:
* Identify hcmcgenecus areas (i.e., sections of insulation that appear uniform in color and texture).
* Take samples for each hcmcgenecus area where the insulation is . darragpri or exposed. Renenfcer, all persons taking samples should
wear a respirator.
* Subnit samples to Analytical Services fer analysis.

Procedures far ether ACM
Most ACM in this category (e.g., wallbcard, ceiling tile, floor tile)
is hard and ncnfriable, and saroling would damage it and release fibers
needlessly. Information cn asbestos in these materials canes mainly
from building records or building personnel. Dorrrent the presence and
location of these
in permanent records. Although ncnfriable
asbestos is of less mediate concern, it shaild net be ignored.
Fibers will be released if ncnfriable material is cut, drilled, or
broken during building repairs or renovation.
Potential Fiber Release
The need for asbestos monitoring depends on the likelihood of fiber release from the asbestos containing material. The possibility of fiber release should be assessed by evaluating the material's condition, physical characteristics and location.
If water or physical damage, deterioration, or delaminaticn of the material is evident, then fiber release has occurred, is occurring, or is likely to occur. The appearance of the material and the presence of broken or crumbled material on horizontal surfaces indicate fiber release.
Visible, highly accessible materials in areas frequently used or
needing periodic maintenance are most vulnerable to physical damage.
Also in this category are rat-p-H al <=: subject to vibration from
mechanical equipment. ACM in an air plenum or near a farced airstream
(e.g., air fran a heating vent) is likely to suffer surface ercsicn.
In addition, fibers released into an airstream may be transported to
other parts of the building, possibly exposing more people. Any
planned changes in building use should
be considered when
assessing potential
release.
