1. Do not store chemicals in or under the fume hood.
2. Before use, check to see if the ventilation system and other parts are in good condition.
3. When operating, stay away from it at least 15cm, and try to reduce abrupt movement inside the hood or in front of the hood face. Minimize the movement of people in the lab.
4. Do not store items that would stick out of the cabinet or jam the closure of the glass window.
5. Do not block the exit of the fume hood or the opening beneath the deflector. If one has to store items in the hood, elevate and place them on the sides. Elevate them from the fume hood work surface so that air will pass underneath them, and put them away from any contamination sources.
6. Check the exhaust performance regularly. Maintain the véntilating effect. Do not-am the air outlet with paper or light objects.
7. During experiments, do not extend the head and upper body into the fume hood; the operator should adjust the glass window to elbow height so that the chest and above are protected. When not operating, lower the glass window to 10-15cm from the bottom.
8. If there is mal-function, do not conduct any experiments. Instead, immediately close the hood window and contact maintenance personnel for repair.
9. After each use, clean the work platform and equipment thoroughly. Close the glass window. For contaminated fume hoods, hang some clear warning signs and notify other people to avoid unnecessary damage. (This article is from Zhejiang University.
