Indoor asbestos pollution: application of hazard criteria

Asbestos contamination of relatively contained environments within structures can occur under many conditions and in association with various activities. Such contamination persists and can potentially expose all structure users. The more significant contamination levels are associated with disturbance of friable asbestos-containing materials, although bonded material is also capable of fiber dissemination under special conditions. Application of occupational government standards for limitation of exposure, both presently in force and proposed or recommended, indicates that levels found in some situations exceed those considered potentially carcinogenic.
