Asbestos was extensively used in a wide variety of products until the 1980s. The material was popular because it was inexpensive and provided numerous benefits such as its strength and resistance to heat. Asbestos, however, is dangerous under certain circumstances. Due to the nature of asbestos, health issues may not become apparent for many years.
Danger in the Air
Asbestos containing materials are dangerous when the product is disturbed. This causes microscopic fibers to be released into the air. Asbestos is also considered dangerous when it is friable, which means that it can be easily crumbled with little pressure. Friable asbestos is more susceptible to having its fibers released into the air. Sprayed-on asbestos insulation is considered highly friable, whereas asbestos floor tile is not.
