Many NIOSH employees serve as commissioned officers in which organization?

The correct answer is the Public Health Service. Many NIOSH employees serve as commissioned officers in the U.S. Public Health Service (PHS), which is a part of the Department of Health and Human Services. This service is responsible for protecting and advancing the nation's public health. NIOSH, as part of its mission to prevent work-related injury and illness, works in conjunction with the PHS and utilizes the expertise of commissioned officers who have specialized training in public health and safety.

Commissioned officers in the PHS often take roles related to research, data analysis, and fieldwork that align with NIOSH's objectives and initiatives. Their involvement enhances the capacity of NIOSH to address various occupational health issues effectively. Thus, the connection between NIOSH and the Public Health Service directly supports the agency's work in promoting safety and health in workplaces nationwide.
