The problem was accidentally caused by a power-washing project at 46 Norway Street that broke open the asbestos shingles on the exterior of the home. Another contractor was hired to complete indoor air monitoring at the three homes today to determine whether there is a serious enough health risk for the residents to warrant an evacuation. Officials believe that the releases of asbestos particles may have been minimized by wet weather conditions.
Asbestos is primarily a health hazard when dry fibers become airborne and are inhaled.
Airborne asbestos is classified as a hazardous substance and is a known carcinogen. Because it is durable, waterproof and fireproof, asbestos had been commonly used in building construction until the late 1980's when it was eliminated from most consumer products.
