Which device is designed to limit exposure to hazardous fumes, vapors, or dusts?

• A. Fume Hood
• B. Ventilation system
• C. Biological Safety Cabinet
• D. Dust Collector

Answer: (A)

Fume hood is designed to protect you from hazardous fumes, vapors, and dust by capturing contaminants at the source. A built‑in blower pulls air from the workspace into the hood and exhausts it outside (or through appropriate filtration), so the breathing zone stays relatively clear of dangerous substances. This containment at the point of emission minimizes exposure the moment you’re handling volatile chemicals or dusty materials. A general ventilation system just dilutes air in the room and doesn’t guarantee that fumes are captured before they reach you, so it’s not as reliable for active containment. A biological safety cabinet focuses on protecting people and products from biological hazards and uses HEPA filtration, but it’s not intended for chemical fumes or vapors. A dust collector targets solid particles and isn’t designed to remove gases or vapors, which can still pose inhalation risks. So, for limiting exposure to fumes, vapors, or dusts at the source, the fume hood is the best-fit choice.
