Which class includes toxic materials such as potassium cyanide?

1. Class 4

2. Class 5

3. Class 6

4. Class 8

The correct answer is: Class 6

The classification that includes toxic materials like potassium cyanide is Class 6, which specifically pertains to toxic substances. This class is designated for materials that can cause serious health risks through exposure, either immediately or over time. Potassium cyanide, being a highly toxic chemical used in various industrial applications, falls into this category due to its potential to cause harm through inhalation, ingestion, or skin contact. Class 6 also encompasses a wider range of hazardous materials that pose similar toxicological concerns, which emphasizes the necessity for careful handling, storage, and transportation practices to mitigate risks associated with exposure. This classification is pivotal for ensuring proper labeling and adherence to safety protocols, thereby protecting individuals who may come into contact with the substance.
