First, I only do special inspections anymore when I have the time as I was promoted up the chain and second we require all the holes to maintain the fireblocking in one and two family dwellings, not firestopping. We deal with firestopping in commercial applications and we do have some local requirements that govern this application as well. We do not look at the fill for the hole being drilled.....we do look for damage to the cable for trying to cram more cables in a hole thus damaging the cable's jacket....but thats about the department has time to concern themselves with at this point.
Secondly, I have never failed anyone whom follows the, state adopted building codes, NEC? and/or local requirements set forth by city council, the mayor and the city charter.
Have a nice day !
FYI- Here is a nice article on it : http://www.fomo.com/building-technologies/from-the-experts/fireblock-vs-firestop.aspx
Thanks Paul, and the only reason I wrote that is last year I did a duplex on w. cary. You "personally" came in and told me about the NM cables in a hole to be firestopped. Actually, this was your ONLY recommendation to me on that day, so I assumed it was important to you. Thanks, again Paul. See you later.
