Bridget,

You should check with ACM Solutions to see if they offer this service. 

We used them to remove a contaminated perchloric acid hood.

Hello everyone,

I have had several colleagues reach out to me looking for methods or a service provider for cleaning the ductwork attached the fume hood system or attached to LEV.  Many of these facilities are 35 – 50 years old and have been used for solvents, resins, light ends and a myriad of chemicals.  One lab in particular recently reported yellow “goo” dripping from one of the LEV nozzles.

 

If you have some information, I would greatly appreciate it.

Thanks,
