What SWCAA requires in an inspection report
SWCAA 476-040 sets the inspection standard for Clark County. These points are a practical way to check a report before work begins.
Sampling minimums
Surfacing materials such as sprayed ceiling texture need at least three samples from each homogeneous area up to 1,000 square feet, five up to 5,000 square feet and seven beyond that. Thermal system insulation needs at least three per homogeneous area, apart from limited federal exceptions. Miscellaneous materials, which include flooring, mastic and siding, need one sample under 100 square feet and three at 100 square feet or more. Only wallboard samples may be composited.
Report contents and limitations
A complete report gives the inspection date; the inspector’s name, signature, certification number and expiry; the site address; and a description of the structure including its approximate age. It states the purpose and any limitations, such as rooms that could not be reached. Each asbestos-containing or presumed material is described by color, location, approximate square or linear feet and condition, next to exact sample locations and the full laboratory report.
Posting and keeping the report
The full report, not a summary, is posted in a visible spot at the work site for the whole project, even if every sample came back negative. During demolition, where posting may not be practical, it stays readily available and a written summary goes to anyone who may contact the material. The owner and the inspector each keep a copy for at least 24 months.
Testing usually leads into a removal service, from popcorn ceilings to cement siding; Vancouver WA Asbestos Removal lists every service on its homepage.
