Asbestos is a naturally occurring mineral found in certain rocks.
This mineral separates into strong, thin fibers that are invisible to the naked eye. ACM can be friable or nonfriable. When dry, nonfriable ACM cannot be crumbled or reduced to a powder by hand pressure. If ACM is in good condition and left in place, it should not present health risks. However, if the ACM has been damaged or is crumbling, or if a building is to be demolished, renovated, or remodeled, care must be taken to prevent the release of asbestos fibers into the air.
