Hello all, 


Can a perchloric acid hood be repurposed as a standard fume hood for typical chemistry reactions? Are there any limitations?


There are some older perchloric acid hoods, but the wash down cycle is no longer functional (perchlorates have been addressed). There is no anticipated work with perchloric acid. The exhaust fan is still operational, and can draw an appropriate face velocity.



Thank you.
