Stability is not commonly recognized as a characteristic of hazardous materials. In the context of hazardous materials, characteristics such as flammability and corrosiveness denote specific risks associated with the material's behavior under certain conditions. Flammability refers to the ability of a substance to easily ignite and burn, representing a clear and significant hazard in fire-related scenarios. Corrosiveness indicates the potential for a substance to damage or destroy living tissue or structural materials upon contact.

Invisibility, while it may apply to some forms of hazardous materials (like gases or certain vapors that cannot be seen), is not inherently a characteristic that defines the nature of all hazardous materials.

By contrast, stability refers to a material's ability to remain unchanged under normal conditions. While some hazardous materials can be unstable and pose risks due to their reactivity, the concept of stability itself does not qualify as a generalized characteristic that defines hazardous materials like the others do. Hence, it is accurate to identify stability as not being a common characteristic of hazardous materials.
