I am not currently the person who is responsible for our lab fume hood testing, our metrology department does that. They wrote a procedure for this task but did not include an upper limit for face velocity. I was cited for this when we had an outside safety audit done, with the recommendation being that we have a upper limit for fpm of 150.
This made sense to me, my understanding was that an upper limit of 150 fpm (or even 120) was generally standard. I would like to learn more about ventilation and take over responsibility of the fume hood testing at my facility.
My question is:
• Is training highly recommended or even required to test chemical fume hoods?
• Does anyone have a recommendation for training?
• Should I indeed be looking at 150 fpm as an upper limit? I have looked at ANSI, NRC, etc., but have not purchased the actual documents.
Thanks you,
Pat
