Kewaunee Fume Hoods: Use, Inspection and Maintenance

What is the best way to use a fume hood?

A fume hood (also known as a fume cupboard or fume closet) is a laboratory local ventilation device. By providing ventilation, fume hoods limit the possibility of contamination. Fume hoods prevent contamination by drawing air through the mouth and away from users and laboratories.

Inspection

A fume hood is a vented enclosure used to keep gases, vapors, and fumes contained. If a hood fails an inspection, it may have to be removed from service until fixed. The International Safety Organization (National fire protection) does have a laboratory fire safety standard.

Access to dangerous fumes, vapors, gases, and dust is reduced when a fume hood is appropriately constructed and maintained. When not in use, keep all materials in airtight containers. Prepare for an emergency, especially if you're working with hazardous materials or acids.

Maintenance

If properly maintained, fume hoods may keep employees safe for years. Manufacturer suggestions frequently relate to individual items that should be addressed on an annual basis. The specialist can do face velocity testing, smoke visualizations, and tracer gas tests on your fume hood.
