I agree 100% with Peter's comments, below. I would also go further to clarify that one of the components of the work space that must be considered is the people who work there. In our case there is a broad range of user knowledge among our graduates and undergraduates doing independent research. We cannot count on them to follow the necessary work procedures to maintain containment in a hood design that requires it for proper function.

Yes, a hood can have good containment with only 60 fpm face velocity, but that can be reliably achieved only with extremely good design and maintenance of the entire room in which the hood is placed. In my opinion, simply buying a hood that claims to demonstrate good containment at 60 fpm, without reference to the details of its intended location, is folly.
