Whether the hazmat response you’re facing is an immediate emergency, emerging situation or preparation need, you have too much on your plate to waste time searching through thousands of search results to find the credible information you need.

The Hazmat Fusion Center mission is to short-cut this for you—to be your one-stop-shop to access hazmat-focused training and resources.

In this section, you’ll find information and tools organized by modes of transportation and commodities format.

Transportation Modes


As with other modes, the FRA is responsible for the hazardous materials transported across the nation’s rails. This is accomplished in a few ways: there is the adherence to codified regulations, direct inspection and enforcement, and collaboration with other modes as many hazardous materials is carried/trans-loaded across multiple modes before it’s delivery.


The Pipeline and Hazardous Materials Safety Administration (PHMSA) operates in a dynamic and challenging environment. The scope and complexity of our safety mission will continue to grow, requiring that we fundamentally rethink how we will use data, information, and technology to achieve our safety goals. PHMSA is the regulatory mode of the U.S. DOT especially in the areas of pipeline and hazardous material safety transportation.


The U.S. Department of Transportation (DOT) began in April 1967. They are entering their 50th year of service to the citizens and visitors of the United States. Their mission is to service the United States by ensuring a fast, safe, efficient, accessible, and convenient transportation system that meets our vital national interests and enhances the quality of life of the American people, today and into the future.


FAA’s Office of Hazardous Materials Safety strives to increase safety in air transportation by preventing hazardous materials accidents and incidents aboard aircraft. Over 100 special agents dedicated to enforcement and educational outreach, ensure compliance with U.S. Department of Transportation (DOT) regulations.


The Maritime Administration (MARAD) is the agency within DOT that represents maritime transportation interests with other federal agency partners including EPA, OSHA, the USCG and other DHS agencies. Through the Office of Environment and Compliance, MARAD facilitates a balanced approach between the needs of safety, security, the environment and commercial mobility.

DOT's Hazard Classification System

The hazard class of dangerous goods/commodities is indicated either by its class (or division) number or name, for example:

Class 1 – Explosives

Division 1.1
Explosives which have a mass explosion hazard

First responders in the U.S. are trained to help identify a hazardous material during the first 15 minutes of an incident, based on the U.S. DOT/PHMSA's Emergency Response Guidebook.
