How does asbestos enter the air?
The most common way that asbestos fibers enter the air is by disturbing or hitting the insulation which breaks the deteriorating insulation apart. These actions can be concealed by covering asbestos pipe insulation with rewettable pipe lagging cloth wrapped around the insulation.
