Asbestos is only a hazard when small particles become airborne, are inhaled and deposited within the lungs. Increased incidence of several illnesses including asbestosis, a debilitating lung disease, lung cancer and mesothelioma, a rare cancer of the lung or stomach cavity lining, have been observed in individuals who were persistently exposed to high levels of airborne asbestos in work environments such as mining, milling, shipbuilding, construction and manufacturing. Asbestos-containing materials in buildings pose no risk to health unless asbestos fibers become airborne and are inhaled. Intact, sealed and undisturbed materials are not a hazard.
Construction products in good condition will not release asbestos particles into the air. Hard products such as vinyl floor tile and cement shingles contain binders that completely encapsulate the asbestos for added protection. Asbestos in soft products such as pipe insulation may be completely sealed within a canvas or steel jacket. Walls, ceilings and floors may also act as barriers that separate occupied building areas from asbestos products found in mechanical rooms, crawlspaces and attics.
Protective Measures - General
EH&S is involved in an on-going effort to survey and identify asbestos-containing materials in the nearly 800 buildings on campus. If these materials are to be disturbed through demolition, building repair or abatement, specific safeguards (photos), must be followed to prevent exposure. Signs and labels (photos) are also used to demarcate asbestos products and abatement activities.
All renovation or demolition of campus buildings must be reviewed in advance by EH&S. If survey information is not available, EH&S will conduct a survey and designate acceptable safe work practices for abating asbestos-containing materials. Work that requires removal or repair of asbestos-containing material or the testing of suspect material is restricted to trained and certified individuals working under the direct supervision of EH&S.
