When should a fume hood be used?

• A. Only for solid samples
• B. Only when the room is cold
• C. When working with volatile, toxic, or odorous substances or when generating aerosols or fumes
• D. When you want to keep a shelf organized

Answer: (C)

A fume hood is there to protect you from inhaling hazardous vapors by drawing air away from you and exhausting it outside the building. Because it captures contaminants at the source, you should use it whenever the work could release volatile, toxic, or odorous substances or generate aerosols or fumes. This keeps dangerous vapors out of your breathing zone and helps keep the lab air safer for everyone. It isn’t about room temperature or keeping shelves organized, and handling solids alone doesn’t determine hood use; if your procedure could produce vapors, aerosols, or fumes, use the hood.
