The laboratories at AT Labs are performing more industrial hygiene analyses than ever. However, over the last few years, the Asbestos market has shrunk and it now constitutes less than 1% of our total revenue. Therefore, in August 2009, we will close down our asbestos laboratory operations to focus our efforts on our other services.

Any samples delivered to AT Labs for asbestos testing will be subcontracted to another AIHA accredited laboratory. We will continue to manage these samples, but it should be noted that there will be an additional cost to handling the subcontracting.

If you have any questions, please feel free to contact our customer service at 800-833-1258 option 4 or myself at extension 8133.

Best Regards,

Steve Green
