Interpretation: While asbestos containing materials in dust at WTC and Fresh Kills is generally below permissible exposure limits for
occupational exposure, the potential for higher exposures exist based on bulk dust and debris samples. Continued use of appropriate respiratory
protection for workers in or near potentially dusty locations or tasks is indicated. Dust suppression measures should be expanded. Additional
personal monitoring underway.
