Which term is not used to describe explosives and any other article defined as hazardous?

The term "composite materials" is not used to describe explosives and other articles defined as hazardous because it specifically refers to substances that are made from two or more constituent materials that have different physical or chemical properties. While composite materials can be used in various applications, including structural components in aviation, they do not inherently have the hazardous characteristics associated with explosives or dangerous goods.

In contrast, "restricted articles," "dangerous goods," and "hazardous materials" all refer to items that can pose risks to health, safety, or the environment. These terms are utilized within regulations and guidelines to categorize and manage substances that require special handling, storage, and transportation protocols due to their potential danger. Understanding these distinctions is crucial in the context of airport operations and firefighting to ensure safety and compliance with relevant regulations.
