as noted previously he is not the "authority having jurisdiction" in the
sense it is used in the nfpa 58 code.

i will dig up the references later this evening.

you are the "authority having jurisdiction" and site the nfpa code 58
defintion and note if asked.

blacksmithing is "industrial processing" therefore meets at least one

plastic deformation of various metal alloys heated to varying
temperatures."
