Asbestos identification is determined by the morphology, visual Selected Area Electron Samples were analyzed Difractioa (SAED), and Biemental Analysis using an Energy Dispersive X-ray Analyzer (EDAX). S=Asbestos suuctures,co=cubic centimeters, mm=millimeter <= less than, Flow Rate In Hters per minute Concentration on the filter is calculated by taking the sumber of asbestos structures and dividing by the area analyzed. Air concentration is calculated by multiplying the effective filter The data pertaining The air filter concentrati accuracy of the filter endorsement of The samples action is considered A reault of zero strictur area (EFA) by the filter concentration and then dividing by the volame of air collected in wabic centimeters (cc). tu these calcnJations can be found oa the Asbestos Count Sheet. ion relates only to air fiber content. When samples are sabmitted by an outside agency for analysis, Envicuscicnce. can only guarantee the concentration. This report may not be reproduced without the express permission of Enviruscience.
