Hazardous materials transport refers to the movement of substances that pose risks to health, safety, or the environment. These materials can include chemicals, biological agents, and radioactive materials. Regulations are in place to ensure safe handling, packaging, and transportation to minimize accidents and exposure. Transporting hazardous materials involves specific guidelines set by organizations like the Department of Transportation (DOT) and the International Air Transport Association (IATA). Proper labeling, documentation, and training for personnel are essential to prevent incidents during transit. Compliance with these regulations helps protect public safety and the environment.
