Ms. Melgetz, Unless all users can assume full responsibilities in the event of a toxic release,ductless fume hoods should not be used in academic chemical laboratories. For further detailed information, see page 34, volume 2 of "Safety in Academic Chemistry Laboratories". Copies of Volumes 1 and 2 are available free from the ACS Council Chemical Safety Committee of the American Chemical Society.
