Unless using a walk-in fume hood, your hands should be the only body part inside the hood. The sash acts as a barrier and is there for protection.
This will allow air to flow beneath it and enable the fume hood to do its job.
Using fans near the hood opening may cause airflow disturbances, which will alter the effectiveness.
Rapid movements can create turbulence, disrupting the flow of air into the hood and may result in exposure.
Likewise, walking near the hood opening or making quick motions may have a similar effect.
It's necessary to have the fume hood open when working inside of it, but when not in use, keep it closed to conserve energy.
To avoid releasing hazardous materials into the laboratory, place materials in a closed container prior to removing them from the hood.
