Buckingham Subject: AIR CONTAMINATION CONTROL ASBESTOS The attached Air Contamination Report shows the long term exposure of employees collaring PA filter tubes and also area concentration levels for the maintenance area of the Tech Building and for the Annex Building. All of the exposure levels are well below the OSHA permissible level of 2 fibers/cc greater than 5 microns in length. At the very low concentrations reported for these samples it is very difficult to determine if the fibers are actually asbestos. R.G. Buckingham Attachment: RGB/dim SAFETY USEI000057 u Q.
