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,
