Which classification is used primarily for corrosive substances?

The classification primarily used for corrosive substances is Hazard Class 8. This class is specifically designated for materials that can cause destruction of living tissue or severe corrosion to materials. Corrosive substances can include strong acids and bases, which are capable of causing significant harm to human tissues upon contact and can also corrode metals and other materials.

In the context of hazardous materials management, understanding the significance of Hazard Class 8 is crucial for handling, transportation, and emergency response. This classification emphasizes the need for protective measures when working with corrosive materials, including appropriate personal protective equipment (PPE) and specific storage requirements to prevent leaks and spills.
