i was in the industrial area in my town today and noticed a white sign with black lettering reading "C F I" posted directly above the fdc and roof truss signs on a remote fdc connection to a commercial building. no one from the building department was around to ask what the sign meant and it puzzled quite a few of us. the building is a bulk perfume bottling and storage facility and we assumed it has some connection to the contents of the building and we have not noticed it prior to the winter months. thought maybe someone out there could shed some light on its meaning. otherwise i will confer with the building department next week. thanks
