Frequently Asked Questions About YEK-FH Fume Hood
A fume hood is a negative-pressure laboratory safety enclosure that prevents volatile, toxic, corrosive, and flammable chemicals from escaping into the laboratory air. Continuous upward airflow (face velocity 0.4-0.5 m/s) protects the operator from chemical vapors and contains spills within the cabinet. OSHA and national occupational safety regulations require that regular work with solvents, acids, and toxic reagents take place inside a fume hood.
