ABC Monitoring Inc. was commissioned by the regional authority for the Occupational Safety and Health Administration (OSHA), to conduct a worker exposure assessment for personnel exposed to asbestos in the Staten Island area from October 11, 2001 to June 27, 2011. The exposure sampling and assessment is in response to the collapse of the World Trade Center buildings on September 11, 2001.The terrorist attacks on September 11, 2001, that instantly killed 2,753 people at the World Trade Center (WTC) site; created a huge gray cloud of hazardous airborne debris that covered the lower Manhattan and Staten Island areas. This cloud contained a variety of substances injurious to human health. These materials include asbestos, fiberglass, pulverized concrete, lead, mercury, cadmium, dioxins, PCB’s and a large number of other dangerous substances (Senior, 2004). Destruction of the towers released indeterminate amounts of asbestos that was used to insulate between floors. It has been estimated that the amount of asbestos used in the WTC, to be as high as 1000 tons, but it remains unclear how much asbestos actually became airborne (Senior, 2004). Cleanup at the WTC officially ended on May 30, 2002 and it took 3.1 million man-hours to clean up 1.8 million tons of debris, with a total cost of $750 million (CNN, 2013). It is well established that exposure to asbestos may increase the risk of lung cancer and mesothelioma.
Asbestos Study of WTC Asbestos Sampling Data for Staten Island Area
ABC Monitoring Inc. was commissioned by the OSHA to conduct a quantitative exposure assessment for workers exposed to airborne asbestos created by the WTC disaster. Workers associated with rescue and cleanup activities in the Staten Island area, were the subjects for monitoring from October 11, 2001 to June 27, 2011.
This exposure assessment was conducted to evaluate the exposures to asbestos and determine if exceeded the standards put forth in OSHA 1910.1001 (c). Results are expressed total fibers and may contain fibers other than asbestos. The permissible exposure limit (PEL) for asbestos is 0.1 f/cc (fibers/cubic centimeter of air) (OSHA, 2011). The sampling approach was intended for identification of what concentrations of asbestos were present in order to provide the public with information if any of the sampling results revealed a significant concern. Phase contrast microscopy (PCM) analysis (NIOSH method 7400) is a technique used for collection and quantification of airborne asbestos fibers (OSHA, 2014). Equipment used for air sampling consists of portable, wearable vacuum pumps
Asbestos is categorized as a substance that causes cancer by the U.S. Department of Health and Human Services, and the International Agency for Research on Cancer (NIH, 2009). Research has determined that asbestos exposure can increase the risk of lung cancer and mesothelioma (NIH, 2009). Asbestos-related symptoms can show no signs of illness for 10 to 40 years or...
