What is 'asbestos-containing material' (ACM) and when does it become a health concern?

BBuilding materials containing more than 1% asbestos by weight; a health concern primarily when damaged or disturbed, releasing fibers into the air✓ Correct
COnly asbestos insulation around pipes; safe if painted over
DAsbestos found only in pre-1945 buildings; not a concern in post-war construction

Explanation

Asbestos-containing materials (ACM) are regulated when asbestos content exceeds 1% by weight. Intact, undamaged ACM that is not disturbed poses minimal risk. Health risks arise when ACM is friable (crumbling) or disturbed during renovation/demolition, releasing fibers.
