Dear Mr. Wooldridge: Tbe eleven air samples that you forwarded for evaluation of
asbestos have been examined using phase contrast microscopy. In all instances the number of asbestos fibers pkr milliliter greater than five microns was less than one.
It would appear that operations were in control when these sample s were taken.
Very truly yours.
