ASBESTOS PERIPHERY MONITORING - ALL ACIDS AREAS
Summary
A program was initiated in January, 1983 to monitor for asbestos at the downwind periphery of insulation removal jobs to determine whether roped off areas for asbestos removal jobs are adequately protecting nearby personnel.
A total.of 19 periphery samplings were conducted by the end of June. The results given in Table I show that all of the samples showed asbestos loadings considerably less than the 8 Hr TLV of 2 fibers > 5 micron in length/cc. Therefore, we have
concluded that the present method of establishing the location of periphery safety rope marking of asbestos jobs is adequate. No further sampling is planned.
The samples were analyzed by either Haskell Lab or Clayton Environmental Consultants using the standard phase contrast method (NIOSH P&CAM 239).
Documentation
The basic data sheets, laboratory analytical reports and calculations are recorded in Notebook 30947.
This memo with attached table must be incorporated the area I/H notebook. We suggest that the monitoring data reviewed with all personnel in your area and be included as part of the OSH 24 Chronic Hazards Training.

2- Monitoring Results
The results of 20 asbestos samplings are given in Table I. Nineteen of the samplings were taken at the periphery and one was taken erroneously at the edge of the building which wa3 app. 55' inside the roped off area. However the "inside the periphery" sample (SE) was also well below the TLV.
Tho se analyses showing a "less than" number value were limited by the analytical limit of the method ( 3000 fibers/filter) JCW:lj A ttachment
