Laboratory Fume Hood Usage Guidelines
Fume hoods are essential local exhaust devices in laboratories, especially in physical and chemical laboratories. Their effectiveness directly impacts the safety of personnel. However, even high-quality fume hoods can present safety risks if not used properly.
Fume Hood Overview
A fume hood is an enclosed workspace designed to control, dilute, and exhaust fumes, vapors, and particles generated within it. It serves as a critical component in preventing chemical exposure and managing leaks in the laboratory.
Fume hoods operate by maintaining a negative pressure environment, drawing fresh air in and expelling contaminated air through exhaust systems. The recommended face velocity is 0.5 m/s or 100 feet per minute, ensuring efficient capture of hazardous substances while minimizing turbulence.
