I love all you guys. I really do. (Even you Todd) But, Hire an Engineer, or Should be provided by an Engineer, just does not work out here in the trenches.
The answer is there in 13. Even "extruding" by a 3-D printer is extruding. I had to do Metal Working for folks cutting 4x8 sheets of aluminum. There is not a distinction. Some AHJ's see that and live by it. IS it the intent? Probably not. But it IS what the book says. Which is the only thing we have in most cases. I really wish we could kick it back. But more times than not, they just go to the next person in line. Just saying. Those are not really answers to the questions. Rant over.. R/ Matt Matthew J. Willis, CWBSP, C.E.T.

The AHJ should have requested that information also. These are tricky operations as dissimilar metals create a deflagration issue. the design may also be outside the scope of the NFPA 13 due to the process involved. Their insurance company should also be requiring a hazard analysis. Craig D. Hanson, CFPS Fire Division Manager West Coast Code Consultants, Inc.

Most of the building is open warehouse where they are producing metal products with 3D printers. NFPA has metal workings listed as ordinary hazard but also has Die Casting and Metal extruding under Extra hazard group 1. Does anyone know where I would start to figure out what hazard is required for this building?
