Employee Exposure

exposure to airborne asbestos that would occur if the employee were not using respiratory protective equipment

High-efficiency particulate air (HEPA)

A filtering system capable of trapping and retaining at least 99.97% of all monodispersed particles 0.3 micrometers in diameter or larger.

5

ACBM with potential for damage

6

ACBM with potential for significant damage.

Thermal system insulation (TSI)

ACM applied to pipes, fittings, boilers, breeching, tanks, ducts, or other structural components to prevent heat loss or gain

disturbance

Activities that disrupt the matrix of ACM or PACM

Friable asbestos material

Any material containing more than 1% asbestos as determined that when dry, can be crumbled, pulverized, or reduced to powder by hand pressure.

Asbestos containing material (ACM)

Any material or product which contains more than 1% asbestos

Category II nonfriable ACM

Any material, excluding Category I nonfriable ACM, containing more than 1% asbestos

7

Any remaining friable ACBM/suspected ACBM

Resilient floor covering

Asbestos-containing floor tile, including asphalt and vinyl floor tile, and sheet vinyl floor covering containing more than 1% asbestos

Category I nonfriable asbestos containing material (ACM)

2

Damaged friable surfacing ACM

1

Damaged or significantly damaged TSI ACM

4

Damaged or significantly damaged friable miscellaneous ACM

Thermal system insulation

Material in a school building added to: pipes, fittings, boilers, breeching, tanks, ducts, or other interior structural components to prevent heat loss or gain

Surfacing material

Material in a school building that is sprayed-on, troweled-on, or otherwise applied to surfaces, such as an acoustical plaster on ceilings and fireproofing materials

Asbestos has been reported in how many products

Over 3,000

Class III asbestos work

Repair and maintenance operations where "ACM" including TSI and surfacing ACM and PACM, is likely to be disturbed

3

Significantly damaged friable surfacing ACM

Asbestos containing building material (ACBM)

Surfacing ACM, thermal system insulation ACM, or miscellaneous ACM that is found in or on interior structural members or other parts of a school building.

intact

The ACM has not crumbled, been pulverized, or otherwise deteriorated so that the asbestos is no longer likely to be bound with its matrix.

Demolition

The wrecking or taking out of any load supporting structural member of a facility

Presumed asbestos containing material

Thermal system insulation and surfacing material found in buildings constructed no later than 1980

Surfacing Material

material sprayed, troweled on or applies to surfaces (acoustical plaster or fire proofing materials)
