Occupational and Environmental Health: Recognizing and Preventing Disease and Injury - Multiple Choice Questions - Learn & Prevent

According to the text, why is ventilation exhaust important in workplaces?

1. To improve air conditioning efficiency

2. To remove hazardous dusts

3. To eliminate unpleasant odors

4. To reduce energy consumption

The correct answer is: To remove hazardous dusts

The correct answer is B because according to the text, ventilation exhaust is important in workplaces to remove hazardous dusts. While options A, C, and D may be important in their own way, they are not the main reason for why ventilation exhaust is important in workplaces. Increasing air conditioning efficiency, eliminating unpleasant odors, or reducing energy consumption are all secondary reasons that may be beneficial, but they do not address the primary concern of removing hazardous dusts in the workplace. It is important to prioritize the safety and health of workers over secondary benefits. Therefore, option B is the best choice as it directly addresses the reasoning given in the text.
