In addition, you need to store different types of chemicals in safety cabinet that are pre-approved by the in-house experts.

  • Minimize all kinds of foot traffic from the face of the hood. You need to make sure that there are no fast movements when you getting things in and out of the chemical fume hood.

  • You must never remove hood sash or panels except when they are to set up any kind of apparatus or equipment. 

  • Last but not least, do not keep electrical receptacles (spark sources for example) inside the range of the fume hood. You should know that no electrical receptacles are ever permitted inside the hood.
Implement all these work practices when using ductless fume hood or any other type of fume hood for that matter.
