Includes covered walkways, porticos and exterior HVAC TSI.
ACCM
(Asbestos Containing Construction Material) – California term for a manufactured
construction material containing greater than .1% (one tenth of one percent) asbestos.
PACM
(Presumed Asbestos Containing Material) OSHA considers all TSI and surfacing materials
installed prior to1980 to be ACM unless proven otherwise.
Friable
Asbestos Containing Material that can be crumbled pulverized or reduced to powder by hand
pressure when dry.

TSI
(Thermal System Insulation) - “Thermal system insulation (TSI)” means ACM applied to
pipes, fittings, boilers, breeching, tanks, ducts or other structural components to prevent heat
loss or gain. “Thermal system insulation ACM” is thermal system insulation which contains
more than 1% asbestos.
SURFACING (usually mixed on site at time of application)
“Surfacing material” means material that is sprayed, troweled-on or otherwise applied to
surfaces (such as acoustical plaster on ceilings and fireproofing materials on structural

Cat II Non-friable Asbestos-Containing Material (ACM) is any material that is not Cat I that
contains greater than 1% asbestos.
RACM
“Regulated Asbestos-Containing Material.” – Friable manufactured asbestos material (ACM)
or a Category I non-friable ACM that has become friable OR a Category I non-friable ACM
that will be or has been subjected to sanding, grinding, cutting or abrading OR Category II
non-friable ACM that has a high probability of becoming or has become crumbled,
