HELP!! NFPA 96 Standard 1991 or Older for Kitchen Hood Fight!!
I am hoping that someone can provide me with the reference(s) from NFPA 96 dating back to 1991 to as far back as 1987. I have the NFPA 96 as far back as 1998. I am fighting an Engineer who is claiming that a non-listed kitchen hood of riveted and screwed-together construction that was fabricated (looks like fabricated in someones garage) in about 1990/91 is in compliance for the addition of a range and oven and that nothing needs to be changed! Prior to the addition of the stove/range, there was just a steamer underneath. In which case it WAS fine then because it was considered a Type II hood. But with the addition of the stove/range, and the introduction of grease laden vapors, a Type I hood is now required. He considers Fire Inspectors to be uneducated/uncertified and unqualified (as stated in previous meetings with this idiot) and keeps referring to older editions apply because the building was constructed in/about 1990-91 and that code is the code that would still apply in this case.
Personally, I believe the hood didn't even meet code at the time it was constructed/installed, but there was no fire code enforcement in place at that time, so it was kind of an "anything goes" Wild West mentality then.
The sections/codes that I am looking for from NFPA 96 pertains to construction of the hoods themselves, and stating that they shall be constructed of a liquid tight, continuous weld to the hoods outermost perimeter as stated in the newer editions of 96. I have scoured Google and other search engines and cannot find the 96 reference I am looking for to win this fight. I've got a copy of a memo dated November 6th, 1992 (which I believe would be spelled out in the 1991 or 1987 Edition of NFPA 96) referring to hoods of riveted construction not meeting code, but I need the code chapter, paragraph and section word-for-word. I am hoping to prove this guy wrong, and want to go into the meeting (scheduled for just after the New Year) armed with this info and hopefully end this argument once and for all and force them to replace the existing hood.
