Define "hazardous material."

The definition of "hazardous material" is focused on the potential risks associated with certain substances. Specifically, hazardous materials are those that can pose a significant risk to health, safety, or the environment. This broad definition encompasses a wide range of substances, including chemicals, biological agents, and physical materials that, under certain conditions, may cause harm to people or the ecosystem.

Understanding this definition is critical in safety training as it underscores the importance of properly managing and handling materials that may be dangerous. It also highlights the need for appropriate safety measures and regulations to mitigate any risks associated with these substances, thereby ensuring a safer working environment for everyone involved.

In contrast, the other choices do not fully capture the essential attributes of hazardous materials. While expired substances or those used in construction can be hazardous in certain contexts, not all expired items are necessarily hazardous, nor are all construction materials. Similarly, while many workplace chemicals are hazardous, not all chemicals fall into that category. This distinction is vital for ensuring effective safety protocols and responsibilities in handling various materials.
