I would have no practical concern about aerosols traversing 4' laterally against the perpendicular airflow of two functioning hoods with 100 fpm face velocities within a foot or two of exhaled breath.


Maybe it's possible, but the risk has to be Extremely minute. Best of luck.

Good morning all,

 

I have 2 4-ft hoods directly next to each other. My dean would like to get a vertical acrylic divider to put between them. He does not want to damage the hoods in any way so this divider would have to be magnetized or hang from the top somehow. He would like proof that this does not impede the air flow in the room. Does anyone have any ideas of how to go about acquiring said proof? What companies do these type of studies? The folks who install and calibrate the hoods?

 

And, is anyone else using such a thing? Or are you allowing people to work next to each other (within 4 ft) for a 3-hour lab? Or eliminating every other hood?

 

Thanks much.

Rose
