Layout of the laboratory and location of the chemical fume hood are both very important for optimum performance and minimal interference. Avoid placing fume hoods near doorways or exits. Ten feet from any door or exit is recommended by the National Fire Protection Association. This is to prevent a fire or chemical release from blocking the exit. Also, to the extent possible, locate fume hoods away from high-traffic areas, air supply diffusers, doors, and windows. Any area that produces air currents or potential turbulence could affect the ability of the hood to capture and exhaust contaminants as designed.
