Date Analyzed: FZA2H <= less than, Flow Rats in Hters per minute using Philips 400F ‘Transmission Electron Microscope. Asbestos identification is determined by the morphology, visual Selected Arca Electron és calculated by taking the number of ashestos structures and dividing by the area analyzed. Air concentration is calculated by multiplying area (EFA) by the filter concentration end then dividing by the volume of air collected in cubic centimeters (cc). The data pertaining to these calculations can be found oa the Asbestos Count Sheet. ‘The air filter concentration relaics oaly to air fiber content.
