What classification is used for substances that can cause damage to living tissue upon contact?

The classification used for substances that can cause damage to living tissue upon contact is Class 8. This class includes corrosive materials that can result in severe injury or destruction to skin and other biological tissues. When handling these substances, it is crucial to understand the risk they pose due to their ability to chemically react with living tissue, leading to adverse health effects.

Class 8 materials are typically linked to acid or alkali substances, which can quickly lead to chemical burns or other serious injuries upon contact. Proper labeling and handling procedures are essential to ensure safety when working with these materials.

Other classifications, such as Class 6, primarily pertain to toxic substances that can cause harm through inhalation or ingestion rather than direct contact with skin. Class 7 covers radioactive materials, while Class 9 encompasses miscellaneous dangerous substances that are not categorized in the other classes. Each classification has specific implications for handling, storage, and emergency response, making it vital to recognize which substances fall under Class 8 for the well-being of individuals working with or around these materials.
