Overall asbestos content for the sample is reported when requested. Specific layer or component asbestos content is indicated when present. These asbestos contents should be considered when establishing policy regarding these bulk materials. Quantification, unless otherwise noted, is performed by calibrated visual estimate. Asbestos in Non-friable Organically Bound (NOB) materials such as floor tiles may not be accurately detected by PLM alone, and the EPA recommends further analysis of "" NOB samples by methods such as gravimetric reduction/transmission Electron Microscopy (TEM). Point counting is not recommended for most non-friable materials unless in certain cases when it is combined with gravimetric reduction. Point counting of many non-friables tends to under report the asbestos content. Results may not be reproduced except in full. This test report relates only to the samples tested.

Copies of the lab data sheets are attached; additional information may be found therein. The results are summarized below: Lab Sample No. Client Field I.D. Sample Description/Location Asbestos Content CL M05 - Firestop, Red - Mechanical Attic - Red Firestop CL M05 - Firestop, Red - Mechanical Attic - Red Firestop CL M05 - Firestop, Red - Mechanical Attic - Red Firestop These samples were analyzed by layers. The overall percent asbestos for the sample is reported when relevant. The EPA considers a material to be asbestos containing only if it contains greater than one percent asbestos by Calibrated Visual Area Estimation (CVAE). EPA regulations also indicate that Regulated Asbestos Containing Materials (RACM) materials that are friable or may become friable be further analyzed by point counting when the results indicate less than ten percent asbestos by CVAE. CatesLab utilizes CVAE on a routine basis and does not include point counting unless specifically requested by the client. The results may not be reproduced except in full.
