Which of the following is an example of a chemical hazard?

Chemical hazards pertain to substances that can cause harm to workers through exposure in various forms, such as inhalation, ingestion, or skin contact. Exposure to pesticides is a clear example of a chemical hazard because pesticides are chemicals specifically designed to kill pests, and they often have toxic effects on humans. When workers handle, apply, or are near pesticide use without proper precautions, they can face serious health risks including respiratory issues, skin irritation, or long-term chronic illnesses.

In contrast, the other options focus on different types of hazards. Slippery floors are considered physical hazards since they can lead to slips and falls. Noise levels present a physical hazard as well, potentially leading to hearing loss if not adequately managed. Inadequate lighting is another physical hazard that can result in accidents or injuries due to visibility issues. Therefore, the unique characteristic of exposure to harmful chemicals makes it the correct choice when identifying examples of chemical hazards in the workplace.
