Whom should I inform if I'm involved in an incident where a release or a suspected release of a hazardous material has taken place in transportation?

Hazardous Materials Regulations (49 CFR Parts 171-180) require certain types of hazmat incidents be reported to PHMSA.

Section 171.15 of the HMR requires an immediate telephonic report (within 12 hours) to the National Response Center. Call the NRC directly (1-800-424-8802); please refer to the NRC section at the top right of this page.

Section 171.16 requires a written report for certain types of hazmat incidents within 30 days of the incident, and a follow-up written report within one year of the incident, based on certain circumstances.

Review both sections under the Code of Federal Regulations section or directly below.

Additionally, the Incident Report Form 5800.1 is a guidance document for preparing incident reports, and tabular summaries of hazardous materials incidents by mode, year, state, hazard class, etc.
