Sample Analysis by: <LOD = Less than limit of detection which is 5.5 Fibers/ 100 Fields Positive Phase Contrast Microscopy (PCM) VOIDI = H.C.P. ( High Concentration of Particles) VOID2 = Overloaded Method of Sample Preparation and Analysis: All samples analyzed in accordance with the NIOSH 7400 Method using "A" Counting Rules. Issue 2, August 1994 Instrumentation: hiwa / ~„'.✓'3w Olympus PCM Model BH-2 with Walton-Beckett Graticule (100um field diameter). Mach I. ` ~iwala Laboratory Director Report Date: April 15,2003 OLC is responsible for only the fiber counts within the limitations of the method described as NIOSH 7400. Among other limitations, this method gives only an index of airborne fibers and provides only an estimate of asbestos concentration. Any and all claims arising out of JLC's analysis of these samples are limited in recovery to the cost of analyzing samples. JLC accepts no other liability and the client agrees to seek no costs beyond the above. Page 49 of 67
