( 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, Augps~,1~ Instrumentation: U am c Iwa a Olympus PCM Model BH-2 with Walton-Beckett Graticule (100um field diameter). Laboratory Director Report Date: April 1, 2003 JLC 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 14 of 19
