Many Americans are surprised to find out that thousands of products were made with asbestos fibers before the substance was declared a hazard to human health in the late 1970s. Chrysotile asbestos fibers were spun and woven into materials to make oven mitts, blankets, and more; while amosite fibers were used within different types of insulation products.
Let's take a closer look at a few of the products made was asbestos throughout the years:
Asbestos ceiling tiles were commonly used in homes and buildings prior to the 1980s. Dropped ceilings, or acoustic ceilings, are likely to contain asbestos-containing tiles. If you own an older home, it would be wise to assume that the ceiling tiles (if any) contain asbestos.
Roofing shingles and felt were both known to contain asbestos. It was used in these products because of its resistance to fire.
Carpet itself usually doesn't contain asbestos, but the padding beneath it might.
These products were used in the construction of both residential and commercial buildings all over the United States. If you live or work in a building constructed before 1990, there is a chance that asbestos-containing materials are present. Be careful not to disturb these products, as asbestos is most dangerous when in a friable state.
