Table 5-4. Hazardous Materials Transportation Incidents
Because most hazardous materials are transported by truck, most incidents related to hazardous materials transportation are on the highways. In 2003, 88 percent of all incidents were highway-related. Moreover, 54 percent of injuries and 77 percent of fatalities in hazardous materials transportation occurred in highway transportation during 2004.
A very small share of hazardous material transportation incidents are the result of a vehicular crash or derailment (referred to as “accident-related”). In 2004, only 2 percent of incidents were accident-related. Most incidents occur because of human error or package failure, particularly during loading and unloading. While only 2 percent of incidents were accident-related in 2004, they accounted for 70 percent of all property damage.

1Water category only includes packaged (nonbulk) marine. Non-packaged (bulk) marine hazardous materials incidents are reported to the U.S. Coast Guard and are not included.
2Other category includes freight forwarders and modes not otherwise specified.
Notes: Hazardous materials transportation incidents required to be reported are defined in the Code of Federal Regulations (CFR), 49 CFR 171.15, 171.16 (Form F 5800.1). Hazardous materials deaths and injuries are caused by the hazardous material in commerce. Accident related means vehicular accident or derailment. Each modal total also includes fatalities caused by human error, package failure, and causes not elsewhere classified.
