1 Feasibility Study for Highway Hazardous Materials Bulk Package Accident Performance Data Collection Bulk packages are a common means of transporting hazardous materials. Accurately estimating the safety performance of these packages in an accident is critical in the evaluation of transportation risks.

2• Bulk Container Damage Information. This information describes the severity of the accident and enables identification of components or locations that are prone to damage and/or release of hazardous materials; bulk container damage information also can be used as a proxy for impact energy and forces involved in the accident.

3 • An industry-sponsored extension of Form DOT F 5800.1 that collects all information required to evaluate component performance, with voluntary participation. • A government-sponsored new database (independent of Form DOT F 5800.1)

4Although the pilot study did not have sample sizes sufficient to evaluate performance based on bulk package design, the information offered a preliminary understanding of component performance by location on the tank, under various accident scenarios. For example, a single incident could damage components in different areas of a tank; therefore, a component in one location might be less likely than one located in another area of the tank to result in a release of hazardous materials.

5 • Damage locations of the rear head below the centerline; the bottom middle, top middle, and/or top front driver-side; and/or the bottom front, top front, and top rear passenger-side. • Whether the bulk package struck the guardrail.

6include taking photos before removing the bulk package. In addition, if damage information must initially be estimated due to a lack of access to equipment following the accident, carriers should be allowed, and even encouraged, to revise that information when they are able to access the accident scene.
