The public library in Salem, Oregon will undergo asbestos removal beginning in January, reports the Statesman Journal. The dangerous mineral has been linked to lung cancer, mesothelioma, emphysema, and gastric cancer. Removal will involve lower levels of the building where asbestos in the ceilings is a prerequisite to replacing outdated light fixtures. Carpets will also be replaced.
According to Salem officials, the asbestos to be removed is encapsulated and is not a hazard unless cut or disturbed. Encapsulation, or sealing the material behind an air- and water-tight barrier, is considered a safer method of dealing with the substance than removing it in its unsealed form. But the risk to both the workers and library patrons should not be underestimated. Microscopic asbestos particles and fibers are enough to cause toxic effects, and any effort to manipulate asbestos may result in dangerous contamination of the area. The Centers for Disease Control Agency for Toxic Substances and Disease Registry notes that significant exposure to any type of asbestos will increase the risk of lung cancer, mesothelioma, and nonmalignant lung and pleural disorders, including asbestosis, pleural plaques, pleural thickening, and pleural effusions.
Unfortunately, disease symptoms may take several years to develop. Mesothelioma may not show up until many years after asbestos exposure. If you are concerned about possible exposure, consult a pulmonologist, a physician who specializes in lung diseases. Recent research suggests that early detection of asbestos-related disease may be possible. Avoiding potential exposure is the safest way to prevent injury.
