What is the Department of Transportation's hazard class for toxic substances?

The Department of Transportation classifies toxic substances under hazard class 6. This classification encompasses materials that pose risks to health through exposure, which can occur via inhalation, ingestion, or skin contact. Toxic substances may be lethal or pose significant health risks, highlighting the necessity for stringent handling and transportation protocols to prevent exposure.

Understanding the classification aids in recognizing the potential dangers associated with these materials, allowing first responders to take appropriate precautions during transportation incidents. It helps in promoting safety measures, proper labeling, and emergency response strategies for dealing with these hazardous materials. The other options represent different hazard classes with distinct characteristics: class 1 pertains to explosives, class 4 encompasses flammable solids, and class 8 includes corrosive substances.
