NIOSH is the National Institute for Occupational Safety and Health. NIOSH is a research and education institution, not a legal enforcement agency. NIOSH is an agency established to help assure safe and healthful working conditions for working men and women by providing research, information, education, and training in the field of occupational safety and health. It does not issue safety and health standards that are enforceable under U.S. law. NIOSH Education and Research Centers are multidisciplinary centers supported by the National Institute for Occupational Safety and Health for education and research in the field of occupational health. Figure 1. Through the centers, NIOSH supports academic degree programs and research opportunities, as well as continuing education for OSH professionals.Founded in 1977, NIOSH ERCs are responsible for nearly half of post-baccalaureate graduates entering occupational health and safety fields.

Rather, NIOSH's authority under the NIOSH was intended to function as an agency at the same level as, and independent from, the Centers for Disease Control. NIOSH was initially placed within the Centers for Disease Control in order to obtain administrative support from the Centers until NIOSH was ready to assume those responsibilities for itself; the Centers, however, never relinquished control and the original intent of the Act never came to pass.Also, pursuant to its authority granted to it by the NIOSH research covers a wide range of fields. NIOSH and OSHA. These goals are supported by NIOSH's program portfolio.

NIOSH continually monitors the products it certifies, as well as the quality control programs of the manufacturers, and revokes the respirator certification when necessary. They share the results of their research through robust education programs. Information pertaining to the specific responsibilities of NIOSH are found in Section 22 of the Occupational Safety and Health Act of 1970 (29 CFR § 671).
