Transportation, Warehousing, and Utilities (TWU) Sector Program

Letter from the Manager, TWU Sector Program

February 21, 2013

Dear Transportation, Warehousing and Utilities Sector Stakeholders:

The Transportation, Warehousing and Utility (TWU) Sector encompasses more than 7 million workers who provide vital and diverse services to the nation. While employment in the TWU sector can be rewarding and fulfilling, the hardworking men and women in this sector face a myriad of workplace hazards that pose threats to their well-being, including injury and health hazards, and sometimes difficult work conditions that can make it difficult to maintain health.

These pages provide information on the NIOSH TWU Sector Program and the NORA TWU Sector Council that collectively utilize partnerships to identify and prioritize research needs, stimulate innovative research, and encourage science-based changes to improve the safety, health and well-being of TWU workers. As Co-Chair of the NORA TWU Sector Council, it is an honor and pleasure to work with the large number of stakeholders who are committed to ensuring that employment in the TWU sector is as healthful as possible. Each stakeholder brings unique perspectives, strengths and resources that collectively can lead to improvements in TWU worker safety, health and well-being.

There has been considerable progress in the approximate 5 years since the NORA TWU Sector Council was formed, and I look forward to continued advances in the years to come. NIOSH and partners have helped elucidate safety and health hazards and identified promising strategies for improving TWU workers’ safety and health. Ongoing research holds great potential for filling additional knowledge gaps and identifying science-based interventions. NIOSH and partners will continue to work together to foster research on the most compelling safety and health concerns for TWU workers, and to ensure that research findings are put into practice for the betterment of TWU workers.

Sincere thanks to all who have contributed to-date to advancing the science, and putting science into action, to improve TWU workers' safety, health and well-being. For those who have not previously been engaged with NIOSH or the TWU Sector Council, we invite you into the fold. While there are limits on Sector Council membership, there are additional ways to contribute as Corresponding members and partners in research and outreach. Please contact any of the program leaders below if you would like additional information or would like to join the effort. As well, please sign-up to receive updates on important TWU research and prevention at

The National Occupational Research Agenda (NORA) is a partnership program to stimulate innovative research and workplace interventions. In combination with other initiatives, the products of NORA are expected to reduce the occurrence of injuries and illnesses at work. NORA recently entered its second decade (2006-2016) embracing the concept that occupational research and translation efforts be oriented around specific industrial groups or sectors.

TWU Sector

The Transportation, Warehousing, and Utilities (TWU) Super Sector is one of ten such groupings within NORA. The Transportation Sub-sector covers all modes of transporting passengers and cargo by air, rail, water, road, and pipeline. The Warehousing Sub-sector consists of establishments engaged primarily in the storage of goods. The Utilities Sub-sector covers electric power, natural gas, alternative sources, water, sewage, and other systems.


The overall mission of the TWU program is to 'implement a focused program of surveillance, research, and the development of interventions that leads to the mitigation and prevention of work-related injuries, illnesses, and fatalities in this broad industry sector.' The NIOSH TWU program sets priorities for NIOSH work in the sector, monitors NIOSH-funded TWU projects and encourages new NIOSH projects to address program priorities. The program also uses some NIOSH resources to facilitate the work of the NORA TWU Sector Council. The TWU program tracks impacts achieved by NIOSH projects and partner efforts in support of sector goals.

Motor vehicle crashes are the 1st or 2nd leading cause of death in every industry sector, including TWU. NIOSH has established the Center for Motor Vehicle Safety () to coordinate efforts to research, prioritize, and identify interventions across all industries. The TWU program collaborates with the NCMVS to develop interventions and injury prevention strategies for TWU workers who are at highest risk of fatality or injury from motor vehicle crashes.

NORA TWU Sector Council

The NORA TWU Sector Council sets national priorities and facilitates the development of partnerships to improve occupational safety and health in the TWU Sector. The Council is made up of approximately 25 individuals who represent diverse interests from academia, state, federal, and local governments, labor unions, non-profits, and trade associations. The Council is co-led by a NIOSH representative and an individual from outside of NIOSH. The Sector Council also draws on an active group of Corresponding Members who participate in ad hoc working groups to help implement action plans developed for specific priority goals. Because the TWU Sector is so diverse, Corresponding Members are valuable sources of specialized knowledge that may not reside within the Council itself.

The Council has been engaged in a broad range of activities over the past several years. These activities have included the conceptualization and development of a national strategic agenda, selection of priority goals and the initiation of strategies to implement priority goal-specific action plans. The chart below summarizes the broad scope of these activities.
