Transportation, Warehousing and Utilities Program

What are our priorities?

The National Institute for Occupational Safety and Health (NIOSH) Transportation, Warehousing and Utilities (TWU) Program works with partners in industry, labor, government agencies, trade associations, professional organizations, and academia. The program focuses on reducing injuries, illnesses, and fatalities among TWU workers, prioritizing areas related to:

  • Transportation and fatigue
  • Human-machine interaction
  • Work-related obesity and chronic disease
What do we do?
  • Use surveillance data and stakeholder input to guide research and prevention efforts in the TWU sector.
  • Research and promote work organization factors and healthy behaviors to reduce fatigue, obesity, and chronic disease.
  • Conduct research and provide recommendations to manufacturers, employers, workers, and others to reduce transportation and machine-related injuries.
  • Work with partners and the National Occupational Research Agenda (NORA) TWU Sector Council to disseminate research findings and prevention recommendations.
What have we accomplished?

Published peer-reviewed journal articles about:

What’s next?
  • Publish a research article on COVID-19 exposure reduction in aircraft cabins.
  • Publish a research article describing directions for improving truck driver health, safety, and well-being.
  • Analyze new data to examine the relationship between working conditions and chronic diseases like diabetes, obesity, and heart disease.
  • Complete discussion groups with TWU industry partners on research needs and accomplishments related to the TWU subsectors.
