S C Is responsible for only the fiber counts within the limitations of the method described as NIOSH 7400. Among ethod gives only an index of airborne fibers and provides only an estimate of asbestos concentration. Any and allother limitations, this JLC's analysis of these samples are limited in recovery to the cost of analyzing samples. JLC accepts no other claims arising out of liability and the client agrees to seek no costs beyond the above. Page 13 of 14
