Sample Analysis by: <LOD = Less than limit of detection which is 5.5 Fibers/ 100 Fields VOID1 = H.C.P. ( High Concentration of Particles) Positive Phase Contrast Microscopy (PCM) VOID2 = Overloaded Method of Sample Preparation and Analysis: Counting Rules. Issue 2, August 1994 All samples analyzed in accordance with the NIOSH 7400 Method using "A" Instrumentation: ivamICfac waa Olympus PCM Model BH-2 with Walton-Beckett Graticule (100um field diameter) Laboratory Director Report Date: November 16, 2001 described as NIOSH 7400. Among other limitations, this meth JLC is responsible for only the fiber counts within the limitations of the method and provides only an estimate of asbestos concentration. Any and all claims arising out of JLC's analysi gives only an index of airborne fibers analyzing samples. JLC accepts no other liability and the client agrees to seek no costs b these samples are limited in recovery to the cost of the above. Page 2 of 2
