The application of ductless hoods in laboratories: What everyone should know

Publication date: Available online 28 November 2015 Source:Journal of Chemical Health and Safety Author(s): Lou DiBerardinis Ductless hoods have been in active use in laboratories for over 40 years. They are attractive due to their size, mobility and less use of energy-relative to ducted chemical fume hoods. While they have some advantages in certain applications, there are also some limitations that must be well understood before their use accepted in particular application. Factors to consider are: can the chemicals used in the hood be identified and controlled, will the vapors gases generated be adequately removed from the airstream before discharge back into the room, is there an adequate management of change program, and is there an adequate testing and maintenance program?
