Which system provides both fire protection and healthy environments?

• A. Dust
• B. Dust collection system
• C. Ventilation
• D. Air filtration

Answer: (A)

Dust control addresses two critical needs in a shop: keeping the air healthy to breathe and reducing a major fire risk. Wood dust is a health hazard when inhaled, and it can also fuel fires if it accumulates or becomes airborne. By focusing on managing dust—reducing, capturing, and containing it—you improve air quality and cut potential ignition sources at the same time. In this context, the concept represented is the impact of dust control as a system that simultaneously supports fire protection and a healthy environment, which is why this option is identified as the best choice.
