PLAINTIFF'S EXHIBIT KRC-727
Enclosed are the analytical results, air monitoring form and employee notification for asbestos monitoring conducted April 22, 1988 for Bennie Terrell (Attachment I). This is the sample found in the IH office during my last visit to Southwestern. The sample was forwarded to Hager Laboratories for analysis.
The airborne concentration for the time monitored is 0.5 f/cc. The eight-hour time-weighted average (TWA) of 0.12 f/cc is below the OSHA PEL of 0.2 f/cc. However, both the eight-hour TWA and the concentration for the time monitored exceed the OSHA action level of 0.1 f/cc.
The 0.5 f/cc concentration is higher than expected for this type of operation. The sample form does not indicate whether a glove bag was utilized during the operation or whether wet methods were employed. This employee should be remonitored on a similar removal to insure that standard operating procedures are being followed.
A computer summary of asbestos monitoring results for 1987 is enclosed as Attachment II. A similar summary for 1988 is enclosed as Attchment III. To date, the facility has completed four asbestos personal monitoring samples. Air monitoring should be conducted each time insulators are removing asbestos containing materials. Operations, involving the removal of gaskets containing asbestos (i.e., where chipping or grinding is employed), should be monitored as well.

REPORT ON SERVICE NUMBER 34681AH June 20, 1988
To: Ms. Janet C. Smith Kerr McGee Corporation Oklahoma City, Oklahoma
Analysis:
The following sample was submitted for analysis: One membrane filter sample and one blank for asbestos count.
Method:
ASBESTOS (count) The fiber concentration of each filter sample was determined following NIOSH Method 7400. Wedges from each filter were examined at 400 power using phase contrast microscopy. All fibers longer than five (5) microns with a length-to-width ratio of 3:1 or more were counted as asbestos.
Results:
The results are found on Table 1.
Discussion: The present OSHA permissible exposure limit (PEL) for asbestos is 0.2 fibers/cc.
LT( ) indicates "less than" with the lower limit of quantification shown in parentheses.
All samples have been corrected for the blank unless otherwise noted.
Laboratory data are filed and available upon request.
Hager Laboratories Inc. has been AIHA accredited since 1977 and EPA approved for asbestos since 1979. A portion of each sample is retained for subsequent review and future analysis.
If you have any questions, please call customer service.
