This is excellent – thank you. I offered back to the inspector that this language is much more precise than the open-end IRC language. Will advise all what is returned.

Here is a link that has a pretty recent draft of this code. This code (with slight edits) has been adopted by the ICC and will become code January 1 2023. See page 486. https://www.iccsafe.org/wp-content/uploads/IFC-2021-Group-A-2021-Group-A-Aug-13.pdf With Regard, Vince Jolissaint Cobalt Power Systems Inc. | Director of CAD Services 2557 Wyandotte St. | Mountain View CA 94043 Office: <tel:650.938.9574> 650.938.9574 | E-Mail <mailto:vince...@cobaltpower.com> vince...@cobaltpower.com Message: 1 Date: Tue, 29 Mar 2022 09:15:23 -0500 From: <scot.a...@solarcentex.com <mailto:scot.a...@solarcentex.com> > To: "'RE-wrenches'" <re-wrenches@lists.re-wrenches.org <mailto:re-wrenches@lists.re-wrenches.org> > Subject: [RE-wrenches] IRC 328 and ESS...approved barriers and "subject to" damage Message-ID: <04e301d84377$6e935c30$4bba1490$@solarcentex.com <http://solarcentex.com> > Content-Type: text/plain; charset="us-ascii" Good morning, Wrenches. We all discuss the NEC when it comes to ESS but the section in International Residential Code (IRC) R328 is something to look at carefully. Easy to miss is the requirement to extend fire alarm systems to garage spaces where we quite often install the ESS. But the section in R328.8 Protection from impact is what worries me as it is so open ended. Here is what I wrote to a city inspector: "I'd like to review this open-ended section of R328 and how you interpret it, please. We intend to mount the ESS within an attached garage but we position so as to prevent damage from vehicles coming into their normal parking space. Having said that, a vehicle that moved five further feet forward might in fact run into an ESS. So do you read "subject to" as in normal, due course or do you consider the very worst scenario / accident? And what approved barriers have you seen that comply to your satisfaction in xxxxx." What do you all do for R328?
