An orange DOT label is specifically used to indicate that the material is explosive. The United States Department of Transportation (DOT) employs a color-coded labeling system for hazardous materials, and an orange label signifies that the contents can undergo a rapid chemical reaction that results in an explosion. This classification is critical for first responders and those handling the material, as it contains crucial information regarding the potential hazards and necessary precautions connected with the substance.

Understanding the specific definitions of the hazardous material categories is vital for safety and compliance in industrial and transportation settings, as each type of hazard requires different handling procedures and emergency responses.
