Exposure Assessment Program At-A-Glance November 2017 The Exposure Assessment Program provides national and international What are our priorities? leadership in the development and use of The National Institute for Occupational Safety and (NIOSH) Exposure Assessment Program works effective exposure assessment strategies with partners in industry, labor, trade associations, professional organizations, and academia. The program and methods to prevent work-related focuses on promoting the use of 21st century exposure assessment sensors, methods, and processes to illness and injury. This snapshot shows protect worker safety, health, well-being, and productivity. recent accomplishments and upcoming work.
