Which term refers to substances that can pose a hazard to health?

The correct term that refers to substances capable of posing a hazard to health is "hazardous substances." This classification includes a wide range of materials that can cause various health risks through exposure, including chemical, biological, and physical agents. These substances can lead to acute or chronic health effects, depending on the nature of the exposure and the specific characteristics of the substance itself.

Understanding hazardous substances is crucial for workplace safety as they can exist in various forms—such as solids, liquids, gases, or even biological agents—and can be found in many different environments. By identifying and implementing proper handling, storage, and emergency procedures related to hazardous substances, workplaces are better equipped to protect employee health and safety.

The other terms mentioned do not accurately describe substances that pose health hazards. Non-toxic materials imply that the substances do not pose health risks, compliance materials refer to items or documents that ensure adherence to regulations rather than describing risk, and safe substances suggest a lack of any potential danger. Each of these terms, therefore, is not appropriate for the context of health hazards.
