Hi all,
A new PI joining our Chemistry Department is sharing a very strong preference for vertically-split fume hood sashes (i.e., ones that open side to side), saying that they’re safer. Is anyone aware of any studies
on this, or have any other insights? Thanks!
Sincerely,

I acknowledge that the land on which I live and work is the ancestral and unceded land of the
Muwekma Ohlone Tribe. As an uninvited guest on these lands, I am a beneficiary of the ongoing displacement of the Ohlone people. I pay my respects to the Native peoples, past
and present.
