What term describes substances like fumes and vapors in the workplace?

The correct term for substances such as fumes and vapors in the workplace is "substances hazardous to health." This classification encompasses a wide range of harmful substances that can adversely affect the health of employees through inhalation, skin contact, or other means of exposure.

Fumes and vapors are often byproducts of industrial processes and can contain various toxic or harmful chemicals. Health risks associated with such exposures may include respiratory issues, skin irritations, or long-term health diseases, which is why recognizing them as hazardous substances is essential for workplace safety and compliance with health regulations.

This term is critical in occupational health and safety, as it underlines the importance of risk assessment, proper ventilation, personal protective equipment, and other measures to minimize exposure to these types of substances. In contrast, the other terms do not specifically capture the notion of health-related hazards presented by fumes and vapors. Physical hazards relate to dangers caused by physical factors, biological hazards encompass harmful organisms like bacteria and viruses, and environmental hazards refer to external risks from the surroundings.
