Painters had used air to blow dirt off of the top of ventilation ductwork in preparation for painting to be done. IH took a bulk sample of material which had been blown off the ductwork. Upon analysis, it was determined that the sample contained a small amount of asbestos. According to Poly II operators, the area had been quite dusty while the painters were working. After IH had been called, the painters were told to stop the operation.

The insulator wore protective clothing and an airline respirator. Samples Z-9206 and Z-9207 were taken after cleanup completion and priority analyzed to determine if the area was cleaned adequately to allow entry. The results of analysis were communicated over the phone and at approximately 2:00 p.ra. on the 24th the area was opened for entry.

Protective clothing and Comfo II half-face respirators with HEPA filters were worn. The respirators were more than adequate to protect against these fiber concentrations. Wet methods were used. The area in which the work was being performed was a small, cramped corner with little room for free movement. This may have contributed to the above results. Use caution when removing asbestos using the glove bag method. Wet methods of removal must be stringently enforced even when used in glove bags. Continue wearing respiratory protection when using the glove bag method. Continue 1H monitoring. Inform insulators of the results of these tests. Microscopy C. R. McMillan/T. L. Grittie JHM Labs D.

Aa one can see from the above data, the use of glove bags where feasible, significantly reduces personnel exposure and should be the engineering control of choice if possible. Sample Z-9052 shows a fiber concentration above the PEL, TWAg of 0.2 f/cc during the sampling period. This concentration is, however, well below the limitations of the respirator. Use glove bagB whereever feasible. Regardless of the method of choice, the material must be thoroughly wetted to minimize fibers in the air. Share thiB information with insulators. Microscopy C. R.
