ACM can be broadly categorized as either "friable" or "non-friable." The Department's definition of "asbestos waste" includes only friable ACM. The specific regulatory definition can be found at 6 NYCRR 360-1.2(b)(11). Asbestos waste is defined as "friable solid waste that contains more than 1 percent asbestos by weight

Reducing the material temperature below its glass transition temperature (T g ), which is the point at which a polymer goes from a brittle, glassy state (low temperature) to an elastic, rubbery state (higher temperature). Materials below their T g are generally friable to some degree. Keeping the mill and material from overheating.

Encapsulation is the application of a material with a sealant to stop it from releasing fibers. Normally, encapsulation is not regulated by the Asbestos NESHAP unless it involves removing or stripping asbestos. However, if encapsulation is done using methods that damage asbestos and release fibers it would be covered.

Shear crushing is normally called for under the conditions when the material is somewhat friable and has relatively low silica content, when the material is soft to medium hardness, or when a relatively coarse product is desired with a minimum of fines. It is usually employed for primary crushing with a reduction ratio of 6 to 1.

Why It Is Important to Have a Friable Soil. The crumbly texture of friable soils not only permits roots and other underground plant parts to thrive. It also strikes the right balance in terms of drainage. That is optimal ground in which to garden drains well enough that it never becomes waterlogged, while, at the same time, retaining sufficient ...

is locked securely into the material. All other non-friable ACMs are considered category II non-friable ACM. Category II non-friable ACMs are more likely to become friable because they are not as resistant to crushing or pulverizing. Certain friable ACMs were banned in the United States in the 1970s, although many asbestos

Materials are classed as friable when they can be easily crushed or crumbled by hand, releasing the fibres into the air. Once asbestos fibres are turned to dust and released into the air, they become airborne and are extremely dangerous. Airborne asbestos fibres look like tiny dust particles and are practically invisible to the naked eye.
