“Asbestos” is a commercial name, not a mineralogical definition, given to a variety of six naturally occurring fibrous minerals. These minerals possess high tensile strength, flexibility, resistance to chemical and thermal degradation, and electrical resistance. These minerals have been used for decades in thousands of commercial products, such as insulation and fireproofing materials, automotive brakes and textile products, and cement and wallboard materials.
When handled, asbestos can separate into microscopic-size particles that remain in the air and are easily inhaled. Persons occupationally exposed to asbestos have developed several types of life-threatening diseases, including asbestosis, lung cancer and mesothelioma. Although the use of asbestos and asbestos products has dramatically decreased in recent years, they are still found in many residential and commercial settings and continue to pose a health risk to workers and others.
NIOSH Asbestos Workplace Safety & Health Topics
Required Asbestos Awareness Refresher Training
Asbestos awareness training is required upon initial assignment and annually for employees whose are exposed to airborne concentrations of asbestos at or above the permissible exposure limit (PEL) and/or excursion limit. OSHA requires a minimum of 2 hours training annually.
Asbestos awareness refresher training, together with additional ‘site specific’ information, meets the annual OSHA (1910.1001) and the EPA Asbestos Hazard Emergency Response Act (AHERA) regulatory requirements.

Asbestos Fibers and Other Elongate Mineral Particles: State of the Science and Roadmap for Research
DHHS (NIOSH) Publication Number 2011-159 (March 2011)
This document is intended as one step in the process. NIOSH intends to pursue partnerships with other federal agencies and stakeholders to help focus the scope of the research that can contribute to the scientific understanding of asbestos and other mineral fibers, to fund and conduct the research activities, and to develop and disseminate educational materials describing results from the mineral fiber research and their implications for occupational and public health policies and practices.
