What is Regulated Asbestos Containing Material (RACM)?
Regulated Asbestos Containing Material (RACM) is defined in BAAQMD Regulation 11, Rule 2 as asbestos which is friable and contains greater than 1% asbestos. Friable asbestos is asbestos which can be crushed, crumbled or pulverized using simple hand pressure when dry. Non-friable asbestos containing materials containing greater than 1% asbestos are also considered to be RACM if they are subjected to sanding, drilling, grinding, cutting, abrading or may be crumbled, pulverized, or reduced to powder during the course of demolition or renovation.
RACM means friable asbestos material, category I material that has become friable or has been subjected to pulverizing, grinding, chipping, sanding or abrading, or category II non-friable ACM that has a high probability of becoming or has become crumbled, pulverized or reduced to powder by the forces expected to act upon the material during the course of renovation or demolition.
