The area sample was above the action level of 0.1 f/cc during the sampling period. However at the end of the monitoring period no further release of fibers was expected since the job was at that time completed. Therefore it can be assumed that over an 8 hour period the actual area concentration was well below the action level. RECOMMENDATIONS: Request further IH monitoring when similar jobs are being performed. Share this information with area and craft personnel. METHOD OF ANALYSIS: Microscopy DATA AND REPORT BY: C. R.

TLG/le 5452A UCC 007281 yjU'o J?(oP ( DATE: PROJECT: DATE OF SAMPLES: INDUSTRIAL HYGIENE RESULTS April 6, 1987. Monitor insulators removing asbestos insulation using the glove bag technique. SSP Unit. K-36, top deck. January 16, 1987. SAMPLE Z-8872 Z-8873 TIME START 10:34 14:31 TIME STOP 11:30 15:29 RESP? Airline Airline CONC. 0.158 fibers/cc 0.272 fibers/cc DISCUSSION; Both of the above exposures were unexpectedly high. Since these exposures do not typically extend for 8 hours, but rather 4 one hour exposures, it is doubtful that an overexposure condition was experienced. This, however is only true if during breaks, lunch, etc. the insulator is not exposed to any asbestos (which should be the case). In addition, airline respirators were worn. The above stated protective equipment and work schedule should however in no way diminish the impact of these f results. I would recommend that we closely scrutinize if the glove bag method of removal is being used properly. The above results indicate that wetting must be used in conjunction with the glove bag. The high concentrations measured are most likely a result of fibers being released during removal of the glove bag from the line. Since this is the most probably time for release of fibers, the glove bag should be thoroughly wetted and evacuated , with the HEPA vacuum before removing it from the line. It is very important that I.H. be called to perform monitoring during similar situations in order to ascertain if these high concentrations are the norm or if this was an isolated incident.

The removal of the transite took less than two hours on both of these days. Z-8886 was above the action level during the monitoring period, but below the PEL. On 1/21/87 area monitoring was performed for 7 hours 8 minutes while the same type work was being performed. This was done to assure that operators entering the area below the roof repair were not being overexposed. As the results of sample Z-8888 indicate there was little to no exposure potential in the area. It also serves to illustrate that when monitored over an 8-hour period the exposure potential did indeed decrease at the end of the time period in which the transite was being removed. RECOMMENDATIONS; Continue to use respiratory protection as a precautionary measure until more samples may be taken to assure that the PEL is not exceeded. Request I.H. monitoring any time work on transite is being performed to obtain more background data. METHOD OF ANALYSIS: Microscopy DATA AND REPORT BY: C. R. McMillan/T. L.

Walker Attached please find the results of the air monitoring for asbestos performed on D&C insulators patching the free standing columns in the Silanes Department. It should be noted that all exposures were considerably below the Action Level. \ IH monitoring will continue on a random basis to develop a more extensive data base. These preliminary results indicate that areas in which similar work is performed need not be considered regulated areas. These low levels would not require coveralls, showers or respiratory protection. The use of coveralls and Comfo II's with HEPA filters is, however encouraged.
