I'm not clear what kind of service you have in mind. In my experience, decon of acid contaminated hoods is a hazmat clean up job that requires a plan specific to the situation (contaminant of concern, hood and ductwork design, resources available, etc.). I've helped organize such clean ups of both perchloric and nitric acid contaminated hood systems and these required an interdisciplinary group with facilities and EHS expertise.

Good luck!
