If something is described as "hazardous," what does this imply about its nature?

When something is described as "hazardous," it indicates that it possesses qualities that can cause harm or pose a risk to health, safety, or the environment. Hazardous materials, for example, can be toxic, flammable, or reactive in nature, making them dangerous to handle or be around without proper precautions.

The term "hazardous" inherently suggests the potential for danger, whether that is physical harm, health risks, or adverse environmental impacts. Understanding this term is crucial in contexts such as workplace safety, environmental regulations, and public health. In contrast, the other descriptions—safe, usual, and beneficial—do not align with the connotation of risk and danger associated with the term "hazardous."
