Which section outlines the criteria for determining the hazard class of materials in transport?

The criteria for determining the hazard class of materials in transport is accurately outlined in 49 CFR §173.2. This section provides guidance on how to classify hazardous materials based on their physical properties, such as flammability, toxicity, and corrosiveness. It establishes the framework for assessing and categorizing materials into recognized hazardous classes, ensuring safety during transportation.

This classification is crucial as it influences not only how materials are handled but also their labeling, packaging, and the safety measures required during their transportation. By having a clear set of criteria, regulatory compliance is maintained, thereby minimizing risks associated with the transport of hazardous materials.

Understanding the hazard class of materials is fundamental for anyone involved in the transport of hazardous substances, as it directly affects planning, logistical decisions, and emergency response strategies.
