OHM Organizational Structure and Phone Contacts

The mission of the OHM is to promulgate a national safety program that will minimize the risks to life and property inherent in commercial transportation of hazardous materials. (Bulk transportation onboard vessels is beyond the scope of this office.)

The functions of the OHM can be consolidated into five categories: regulatory development, enforcement, training and information dissemination, domestic and international standards, and inter-agency cooperative activities. All functions of this office are subject to the executive direction of the PHMSA Administrator, who is advised (by this office) on all hazardous materials transportation safety issues.

Within the OHM, there are seven related offices:

1. Office of Hazardous Materials Standards
2. Office of Hazardous Materials Technology
3. Office of Hazardous Materials Special Permits and Approvals
4. Office of Hazardous Materials Enforcement
5. Office of Hazardous Materials Initiatives and Training
6. Office of Hazardous Materials Planning and Analysis
7. International Standards Coordinator
