Demystify: 

Dear Kathryn, The NIH published a comprehensive guide "Laboratory Fume Hood Specifications and Performance Testing Requirements" (NIH, 2010)on the use and installation of chemical fume hoods. I don't have the url handy, but it is all online. Briefly, the space in front of a fume hood and beside a fume hood are very critical to the safe performance of the hood. Look up the NIH FH Methodology reference as well on line to see the CFD studies that demonstrate the importance of clearances and position of the FH within laboratories.

Hi everyone:

 

One of the labs here is requesting the installation of a new piece of equipment. To do this, the bench top needs to be extended slightly to support the footprint of the instrument. However, the lab itself is somewhat narrow and the placement of this instrument is directly across from a chemical fume hood.

 

Now my question, what is the minimum aisle space needed in front of a fume hood? Everything I come across states “…ensure that there is sufficient aisle space in front of the fume hood.” But what is “sufficient” (how many feet, inches, etc)? If anyone can shed some light on this or provide an actual guideline or regulation, I would greatly appreciate it. I don’t want the facilities group to go through this installation and then find out we are in violation of something.

 

Thanks in advance!

~Kate
