How air tight is to air tight? I may be over thinking this, but a fume hood works off of negative pressure, so basically its sucking in fresh air and exhausting contaminated air into a scrubber. At at what point would a lab could be to air tight that the fume hood could not generate enough negative pressure to extract the fumes?
Looking at building a small shed type building for a lab most likely 10×14ish I highly doubt it will be that tight but I am curious is pumping fresh air in may be a good idea just in case.
I hope that made sense.
