The Lewis Engineers and Scientists Association is particularly concerned about exposure to asbestos-bearing substances that are released through a hole in the ceiling, a spokesman said. Asbestos attorneys caution people who work in facilities built between the 1940's and 1980's due to the nearly universal use of asbestos in construction in those decades. Asbestos, durable, fire-resistant and deadly, works as an insulator but its fibers are difficult to detect in the environment because it is tasteless, odorless and invisible. It can lead to various kinds of mesothelioma cancer, including peritoneal mesothelioma, pleural mesothelioma and pericardial mesothelioma. It can take decades to develop these diseases and mesothelioma treatment is very expensive. The OH&S institute said the cancers at Glenn were not consistent with asbestos exposure. The NASA building is to be demolished next year to make way for a new complex.
