OSHA and elongate mineral particles.

The United States Occupational Safety and Health Administration (OSHA) was established to provide guidance to protect workers from hazards in the workplace. After broadly adopting extant health and safety standards, OSHA promulgated an expanded standard for regulation of asbestos. This standard provided for regulation of six named minerals and practices to be followed. Since the initial establishment of asbestos regulation by OSHA, other elongate particles have been considered for evaluation. This discussion describes the evolution of the OSHA regulations for asbestos, what they cover and how other materials might be regulated if they are found to pose a health risk.
