In 1986, the Asbestos Hazard Emergency Response Act (AHERA) was signed into law, requiring public and private non-profit primary and secondary schools to inspect their buildings for asbestos-containing building materials. Although asbestos is hazardous when inhaled, the risk of exposure to airborne fibers is very low. Therefore, removal of asbestos from schools is often not the best course of action. It may even create a dangerous situation when none previously existed. EPA only requires removal of asbestos to prevent significant public exposure during demolition or renovation. EPA does, however, require an in-place, pro-active asbestos management program for all local education agencies (LEA) in order to ensure asbestos-containing building materials (ACBM) remains in good condition and is undisturbed by students, faculty, and staff.
