What characterizes materials in Class 6?

Materials in Class 6 are specifically categorized as poisonous and infectious substances. This classification encompasses a range of hazardous materials that can pose significant health risks, either through toxicity or infectious properties. For example, Class 6 includes toxic chemicals that can cause serious harm or death if inhaled, ingested, or absorbed through the skin, as well as infectious agents like bacteria and viruses that can lead to disease.

Understanding this classification is crucial for first responders, as it underscores the need for appropriate safety measures and protective equipment when dealing with substances in this category. The focus on their poisonous and infectious nature highlights the potential for severe health impacts, necessitating immediate attention and precise handling to mitigate risks to human health and the environment.

The other classifications pertain to different hazard characteristics: flammable solids pertain to Class 4, materials that react violently with water belong to Class 3 or Class 8, and corrosive materials are also categorized under Class 8. Therefore, Class 6 distinctly relates to the toxicity and infectious potential of these materials, making it essential for awareness and training in hazardous materials response.
