Hazmat Incidents vs. Serious Hazmat Incidents

PHMSA revised the definition of a serious incident in 2002. This report uses both definitions:

* This is the previous definition:

• a fatality or major injury caused by the release of a hazardous material,
• closure of a major transportation artery,
• the evacuation of 6 or more persons due to the presence of a hazardous material,
• a vehicle accident or derailment resulting in the release of a hazardous material.

This is the current definition:

• a fatality or major injury caused by the release of a hazardous material,
• the evacuation of 25 or more persons as a result of release of a hazardous material or exposure to fire,
• the alteration of an aircraft flight plan or operation,
• a vehicle accident or derailment resulting in the release of a hazardous material.
• the release of radioactive materials from Type B packaging,
• the release of over 11.9 gallons or 88.2 pounds of a severe marine pollutant, or
• the release of a bulk quantity (over 119 gallons or 882 pounds) of a hazardous material.
