SIGNIFICANCE: Job is currently in progress - independent lab analysis claims to have found 3-5% asbestos. We need to check sample. SPECIFIC OBJECTIVE: Material is supposedly MK-5. We need to verify type and determine that, in fact, no asbestos is in the material. SUGGESTED APPROACH: } DEADLINE (Last day information vill be of value): December 10, 1979 DETAILS OF PRQBLQ4: Lab reports 3-5% in MK-5 on job currently in progress; customer deeply concerned over this report. We need to verify that material is asbestos; frfase-testing lab should also be contacted.

Samples were obtained from Grace field representative on site, and material was given to us by Shimel and Sor Testing Laboratory, in which they claimed to have found 3-5% asbestos. Neither sample showed any detectable asbestos fiber when analyzed in the Grace/Cambridge Research Laboratory, but we had found an appreciable amount of glass fiber and organic cellulosic fibers. We have contacted Dr. Carl Sor of the Shimel & Sor Laboratory, and have requested data they used for their evaluation. They have sent the micrographs of fibers at 400X magnification; one labelled "glass", and the other "asbestos" (pic tures attached). From our experience in light microscopy and morphology of the fiber, it is suspected that the "asbestos" is really an organic cellulosic fiber. High temperature calcination of a -20 mesh sample (16 hours at 500C) should clear this point. It is concluded that the MONOKOTE used in this job is MK-5; no asbestos in any form was detected. Analysis of split samples is recommended if in dispute. MATERIAL INVESTIGATED: 1) MONOKOTE from Grace field representative, Jim Cintani, North Brunswick, New Jersey, 2) MONOKOTE sample given to us by Shimel & Sor Testing Laboratory in which they claimed to have found 3-5% asbestos. EXPERIMENTAL: 1) Preliminary Examination Several small broken pieces were examined with a Stereo Zoom Microscope at 100X and found to have some fiber present. Some were long, straight and uniform (glass), and some were shiney and flexible which burned with a lit match readily (organic paper fiber). 2) X-Ray Diffraction Analysis Samples were crushed to -100 mesh size and subjected to x-ray diffraction analysis.

US HAT F.: Doc. 12, 1979 They also claimed that the fibers were sent to Seton Hall Medical School, and were identified by polarized microscope as anthophyl1ite. In fact, anthophyllite has high refractive index (1.59-1.63), whereas glass (E-glass 1.547 isotropic) and organic cellulosic fiber (different morphology). It should not be difficult to differentiate one from the other. We could not find any anthophyllite asbestos either. It was recommended to have a split sample analyzed by both parties and to compare the results.
