Asbestos Classifications

There are two basic classifications of asbestos that determine handling requirements: non-friable and friable.

Non-friable asbestos containing material

  • This material can NOT be crumbled, pulverized, or reduced to a powder by hand pressure or in the course of demolition, renovation, transportation, or disposal
  • Examples of non-friable asbestos: Floor backing, gaskets, resilient floor tile, asphalt roofing, and exterior siding.

Friable asbestos containing material

  • This material CAN be crumbled, pulverized, or reduced to powder by hand pressure, which could release breathable fibers into the atmosphere.
  • Examples of friable asbestos: Pipe insulation, ceiling and wall insulation, thermal pipe insulation
