For Surfacing material, theres the 3-5-7 rule, meaning 3 samples from less than 1,000 square feet area, 5 samples from 1,000 to 5,000 square feet area, and 7 samples from greater than 5,000 square feet area. For Thermal system material, with some exceptions, 3 samples should be taken for each homogeneous area.
Aug 22, 2008 If the suspect asbestos material is a surfacing material, the square feet of the homogeneous area is determined which provides the inspector with the minimum number of samples that shall be taken. If the homogeneous area is less than 1,000 square feet, the inspector shall take 3 samples.
Jun 18, 1999 The definition of surfacing material presented at 29 CFR 1926.1101b in the OSHA construction asbestos standard reads Surfacing material means material that is sprayed, troweled-on or otherwise applied to surfaces such as acoustical plaster on ceilings and fireproofing materials on structural members, or other materials on surfaces for ...
Surfacing Materials Surfacing materials are the biggest concern of the AHERA regulation because of their friability andor presence in public areas. The EPA funded the production of a guidance document for sampling friable asbestos-containing materials that was published in 1985. This was years prior to the AHERA regulation.

PACM is defined in the standard and includes thermal system insulation, surfacing material, and vinyl floor tile that have not been shown to contain 1 or less asbestos. ... The bulk sampling procedures used for the collection of suspect ACM first required the
The appropriate selection of sampling location again depends on whether the material is categorized as surfacing material, miscellaneous material or thermal system insulation. 1. Surfacing Material As outlined in AHERA regulation, all friable surfacing material must be sampled in a statistically random manner representative of the homogeneous area.

The AHERA regulations require local education agencies LEAs to identify friable and non-friable ACM in public and privatenon-profit elementary and secondary schools by visually inspecting school buildings for such materials, sampling the materials if they are not assumed to be ACM, and having samples analyzed using appropriate techniques.
containing building materials ACBM and if changes are noticed, then the comments must describe each change clearly. A maintenance person conducting the periodic surveillance would notice water damage, major delamination, a major fiber release, or even minor damage. For surfacing material, damage might include separation of asbestos-containing

the concern for sampling layered materials in a manner so as to reduce risk, as well as the need to comply with recent NESHAP interpretations. The Jan. 5, 1994 Federal Register asbestos NESHAP clarification should be consulted with regard to materials such as joint compound, texturing materials, etc. added to the surface of
SECTION 5 - SAMPLING amp ANALYSIS . BULK SAMPLING . Asbestos bulk sampling is done at District 91 to determine whether or not a material is asbestos containing or to confirm previous analytical results. Since the AHERA regulations have been in effect since 1988, many homogeneous areas have been sampled although some areas are still assumed.
IDENTIFYING SAMPLING AREAS All friable surfacing materials in the building must be identified. Check all spaces in the building, including halls, closets, attic spaces, and tun- nels. Carefully inspect walls, ceilings, beams, ducts, and any other sur- faces. Determine if the material is friable.
Materials are classified as either thermal system insulation TSI, surfacing materials or miscellaneous. Sampling requirements for each classification TSI Asbestos-containing material applied to pipes, fittings, boilers, breeching, tanks, ducts, or other interior structural components to prevent heat loss or gain or water condensation.
For OSHAs purposes, suspect material would include any material including TSI, surfacing, and flooring that a building owner suspects of containing asbestos and is found in a building constructed after 1980, or any material excepting TSI, surfacing, and flooring found in
The purpose of the re-inspection was to evaluate materials previously identified as being asbestos-containing material ACM and asbestos -containing building material ACBM as defined by the Asbestos Hazard Emergency Response Act AHERA located in 40 CFR 763.83 and assess their condition. The facility was visually inspected for ACBM.

This rule requires local education agencies to identify friable and nonfriable asbestos-containing material ACM in public and private elementary and secondary schools by visually inspecting school buildings for such materials, sampling such materials if they are not assumed to be ACM, and having samples analyzed by appropriate techniques referred to in this rule.
Abstract. Asbestos abatement carried out in schools is subject to regulations under the Asbestos Hazard Emergency Response Act of 1986 AHERA. The AHERA rule 40 CFR Part 763 includes procedures for determining when an asbestos abatement site is sufficiently clean for the containment barriers to be removed.
with a low potential for disturbance. The material is classified as surfacing material. The block coating was sampled and is not classified as Asbestos Containing Material ACM. The sample analysis is enclosed in Appendix A. A detailed map showing the sampling locations can be found in SUMMIT Documentation. 3.8 Concrete Block CB-1, CB-2 and CB-3
Jan 01, 1991 After the abatement site has passed a thorough visual inspection, air samples are collected under aggressive sampling conditions i.e., air blowers are used to dislodge fibers from surfaces and circulating fans keep the fibers suspended during sampling. The air samples are analyzed by transmission electron microscopy TEM.
