What can be the consequence of insufficient ventilation in a workplace?

Insufficient ventilation in a workplace can significantly lead to a higher risk of airborne contaminants. When a space lacks proper airflow, pollutants, allergens, and particulates can accumulate in the indoor air. This buildup can include dust, mold spores, chemical vapors, and other harmful substances that may be prevalent due to materials being used in the workspace or the activities being performed.

Increased concentrations of these airborne contaminants can result in various health issues for employees, including respiratory problems, allergic reactions, and other long-term health effects. Adequate ventilation systems are crucial in maintaining air quality, as they facilitate the exchange of stale indoor air with fresh outdoor air, thereby diluting and removing harmful particles.

The other options reflect outcomes that contradict the reality of insufficient ventilation. For example, improved air quality and increased employee comfort cannot coexist with a ventilation deficit, and enhanced lighting conditions typically rely on factors unrelated to ventilation.
