Which type of materials falls under the category of miscellaneous asbestos by NYSDOL?

Miscellaneous asbestos materials, as categorized by the New York State Department of Labor (NYSDOL), typically include items that do not fit neatly into the major classifications of asbestos products. Roofing felt and mastics are considered miscellaneous because they are often used in construction and maintenance but don't belong to the more defined categories of insulation or cement products.

Roofing felt is a material that provides a waterproof barrier, commonly used in roofing systems, while mastics are adhesive substances used to bond materials together or to seal joints. Both materials can contain asbestos and are treated as miscellaneous due to their varied applications within construction. This classification highlights the potential health risks associated with asbestos-containing materials that may not be immediately identifiable as hazardous.

On the other hand, textiles, insulation, and cement pipes represent more clearly defined asbestos applications, typically falling into well-established categories of asbestos products with specific regulations attached to their handling and disposal. Thus, roofing felt and mastics appropriately fit the definition of miscellaneous asbestos materials.
