Which scenario describes a potential exposure to poisons in the workplace?

The scenario involving a construction worker working with hazardous materials accurately describes a potential exposure to poisons in the workplace. In construction environments, workers may encounter a variety of hazardous substances, including chemicals that can be toxic if inhaled, ingested, or absorbed through the skin. These materials can include solvents, adhesives, and asbestos among others, which can pose serious health risks if proper safety protocols are not followed.

On the other hand, organizing files, cooking with healthy ingredients, and lecturing in a classroom generally do not involve hazardous substances that could lead to poison exposure. The risks associated with those scenarios are comparatively lower, focusing more on ergonomic or non-toxic hazards rather than the direct exposure to potentially harmful chemicals or materials found in construction work.
