Good morning all,
I was asked to look into the recommended face velocity for fume hoods of
125 linear feet per minute (lfpm). Specifically, I am looking for the
origin of this recommendation, if there is any regulation requiring this
face velocity, and measurement protocol/requirements. I have Shapiro's
text (4th edition) that does cite the 125 lfpm but doesn't give the
source nor measurement protocols. My colleagues and I assume that the
measurements should be made with the hood sash open about 30 - 40 cm,
although I've heard about measurements being made with the hood fully
Any leads would be greatly appreciated.
The statements and opinions expressed herein are my responsibility; no
one else (certainly not my employer) is responsible, but I still reserve
the right to make mistakes.
