                I would strongly recommend not using ductless fume hoods for a number of reasons. Especially if you are building a new facility can put in ducted fume hoods to meet your needs. We do not allow non-ducted fume hoods at our facility.

Thank you.

Subject: [DCHAS-L] Fume Hoods

Dear colleagues:

We are in the process of building a new Laboratory and contemplating between using Dustless Fume Hoods vs. Ducted Exhaust Hoods. We will be using a variety of hazardous chemicals including carbon disulfide, acetonitrile, toluene, benzene, some carcinogenic suspect chemicals, hydrogen sulfide and sulfur dioxide gases.

I appreciate sharing your experiences with ductless fume hoods and whether you recommend these type of hoods for hazardous chemical work using the aforementioned chemical examples as well as advantages and disadvantages of these hoods vs. the ducted exhaust hoods (safety concerns, costs, maintenance, etc.)

Thanks,

Michael Hojjatie, Ph.D.

R&D director, TKI
