The correct identification of substances that are corrosive or toxic falls under Hazard Class Number 6. This class includes dangerous goods that can cause significant harm through various means, such as through contact with skin or inhalation. Specifically, it encompasses toxic substances and infectious materials, which can pose serious health risks.

A deeper understanding of Hazard Class Number 6 reveals that it includes materials that, even in small quantities, can cause adverse health effects or fatalities. This classification also addresses the need for appropriate labeling, handling, and response strategies to mitigate risks associated with these hazardous substances.

Other hazard classes do not focus on the corrosive or toxic nature of substances. For instance, classes related to explosive materials, flammable liquids, or reactive solids deal with different kinds of chemical hazards. Hence, Hazard Class Number 6 is distinctly relevant for identifying hazards associated with corrosiveness and toxicity.
