We are looking at decommissioning an acid hood in the lab that has been heavily used with HF.  All of the visible surfaces have been decontaminated.  While I am familiar with the risks of perchlorate salts with perchloric acid hoods, I was curious what risks might be involved with "down the line" ductwork modification in a hood system heavily used for HF.
