Does anyone know if ductwork used to ventilate hoods has to be disposed of as hazardous waste? We are planning to replace/upgrade some fans and controllers. Two hoods are used for extractions and acid procedures. I was asked about need for hazardous disposal. Certainly the chemicals we use in the hoods produce vapors that are hazards. However, I am not sure whether that requires hazardous waste company.
