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.
