Oh yes, 100% agree. I cannot tell you how many times I have had the 7k discussion.
I also cannot tell you how many times that same discussion met a brick wall, with some "looking down the nose". You see, I am just a simple sprinkler man and am treated as such by those that know better than I due to a piece of paper. Even though I am far more versed in IBC than they. I am more so back to the original example. I have been around this long enough to know what I do not know. To that end, I am wholly unfamiliar with the process or hazard presented to me in that example. All I see and understand are "Metal Working" and "Metal Extrusion". I know that is more than likely the big 2000 gallon buckets of melted steel. Extruding it means it is pushed thru a cylinder, making it a huge round shape. So when I see those words on the Owner's Certificate, and on the Contruction Docs prepared by professionals, and I can then find the same wording in my book.. Well, knowing nothing about it, guess where I ended up thru no fault of my own. In that case, all I can do is stay within my lane. Trusting that the professionals have provided me with the "When". I can then go about finding the "how". R/ Matt Matthew J. Willis, CWBSP, C.E.T.

I do think you have to be at least conversant in the IBC. Here’s an example: I am putting a price together on a 3 story wood frame apartment building. The cover sheet on the building plans says “To be sprinklered”. At first look, you might think 13R as it meets the occupancy and height requirements, based on NFPA standards alone. However, if you look into the Code (IBC), The area of the building is greater than is allowed for a building of Class VB construction with a 13R system, therefore it has to be a full 13 system. If this was designed as 13R and submitted, what is going to happen when it gets rejected? Remember, NFPA documents (except 5000) are standards, they tell you how to design and install a system. Codes tell you where they have to go and reference what standard to design to.

Hell, I even asked Craig to send his directly as I cannot receive his responses for some reason. I had typed a response and then deleted it thinking Nah, to long-winded for a Friday. However since John picked up his copy of 13 and beat me about the head and shoulders with it, just kidding my friend, I have re-created my initial response below. Yes. if there has been a change in occupancy, which is what this may seem like, then an engineering analysis is required in accordance with NFPA 13. However, too many times we as sprinkler designers receive information from the architectural/engineering design team and a somewhat filled out owners information certificates, to be used in making our decisions based on NFPA 13. We receive this information from the professionals. We then use NFPA 13 to arrive at a decision based on the information presented to us by these professionals. In the ever-disappearing time frame before us. I am not allowed to speak to IBC as that is beyond my purview as a fire sprinkler designer. So, it doesn't even come into play. It is actually very dangerous if I choose to speak to IBC in these situations. So, I use the information I have to the best of my abilities. This is done wholly within the confines that are NFPA 13. I fully understand the Annex. BUT the information Is present. It may not be "legal". But it was provided for a reason. Otherwise, I make a motion to delete the annex. We then present this information to the authority having jurisdiction, another professional, for their review and acceptance or rejection. If this then comes back to me for reevaluation, I can at that point then kick it back with suggestions for further consideration. Have I let others take these kinds of projects? Absolutely. And I will continue to do so. Just did this recently on one that made me shake my head so hard, I had to take Ibuprofen afterwards. Many times I will even call the authority having jurisdiction prior to submission and sometimes prior to design to express my concerns. As you might imagine, Owners and GC' Really appreciate this. SMH My whole take is that the problem is getting proper engineering up front. Requiring it at the back end and linking it to a fire sprinkler designer's responsibility to handle is not the proper way to handle this. But it is the Norm, more than the excption. So, we should focus on the real problem which is getting the engineering evaluation upfront and not waiting and placing it on a fire sprinkler designer's shoulders. I know, and have worked with, many of the PE's on this forum. To a person, they are on the same page. It just seems like otherwise this happens far to often. Engineers have E&O. Why are their feet not held to the fire with this blatant shift of Liability? My question is why? Why isn't this being addressed where it needs to clearly be.. Hope this clarifies where I was intending to come from. R/ Matt Matthew J. Willis, CWBSP, C.E.T.

NFPA 13 only references you stated are in the annex which are typical suggestions. The annex list is not to be used without fully understanding the specific process and the actual descriptions in the body of the standard. Relying on the annex for your determination of a hazard could lead to an issue. I also want to state that I really like what I'm reading from other posts. I have been beating the drum for over 5 years categorizing the hazard, water supply evaluations, and other items are engineering. In the real world where lawyers are involved, a technician who does not have a professional engineers license is exposing themselves to liability. The SFPE Position paper 2020-1 which has been endorsed by many associations including AFAA, AFSA, ASCET, NICET, NFSA, NSPA, and others is very clear.. The "Design Basis - Owner Certificate" is the owner's or owner's agent responsibility. Period! NFPA 13 requires this certificate to be submitted with the working plans. A contractor or an AHJ moving forward with a properly signed certificate is asking for increased liability. NFPA 13 -2025 - 28.1.1.1<http://28.1.1.1> - Working plans submittals shall include the following: (4) - Signed owner's certificate Heck - this requirement has been around for a bit. The concept of the Owner's Certificate was included in the 2002 edition of NFPA 13. As part of your proposal and contract for a project, insist on a properly filled and executed certificate. The sample in the annex is a starting point. If you feel the need to add information, make a form and have the responsible party take the liability off you. Feel free to contact me directly if you have any questions on this topic. AFSA's position is clear.and my technical team understands this position. SFPE position's paper is available on the web by searching SFPE Position statement 2020-1, PS 2020-1 The Engineer and the Engineering Technician Designing Fire Protection Systems The above is my opinion and has not been processed as a formal interpretation in accordance with the NFPA Regulations Governing Committee Projects. This is provided with the understanding that the AFSA assumes no liability for this opinion or actions taken on it and they are not to be considered the official position of the AFSA, and/or NFPA or its technical committees.AFSA cannot provide design or consulting engineering services, and this opinion should therefore not be considered, nor relied upon, as such.

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.

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.
