What is a characteristic of Hazard Class 8?

Hazard Class 8 is specifically designated for corrosive materials. These materials can cause significant injury or damage upon contact with living tissue or can corrode materials such as metals. The classification of these substances as corrosives emphasizes their potential to cause severe chemical burns or destruction of body tissues. Therefore, any material that can lead to destruction upon contact with biological tissues or can corrode metals falls under this category.

In contrast, the other choices represent different classes of hazardous materials. Explosive materials belong to a separate category concerning their ability to detonate or explode, while biological agents are classified under their own category due to their infectious potential. Flammable liquids are also categorized differently due to their ability to ignite and burn, often with a considerable energy release. Each of these classes is distinct and tailored to the specific characteristics and risks associated with the materials they encompass, but only corrosive materials represent the defining feature of Hazard Class 8.
