NIOSH has the mandate to assure “every man and woman in the Nation safe and healthful working conditions and to preserve our human resources.“ The Occupational Safety and Health Act of 1970 established the National Institute for Occupational Safety and Health (NIOSH) as a research agency focused on the study of worker safety and health, and empowering employers and workers to create safe and healthy workplaces.

NIOSH is part of the Centers for Disease Control and Prevention, in the Department of Health and Human Services. It has more than 1,300 employees spread across the United States, from a diverse set of fields including epidemiology, medicine, nursing, industrial hygiene, safety, etc. Visit the NIOSH Careers page to learn more.
