RE: [EXTERNAL] Re: Uprights in non combustible concealed space

So, what would make them non-compliant? Obstructions, like ductwork and stuff? When we’ve gotten similar pushback, it’s been because we’ve had 155-degree heads and the inspector has claimed that they aren’t appropriate for an unconditioned space (we’re working in Phoenix, so it can get

Re: Uprights in non combustible concealed space

Yes, it is specified in NFPA 13. NFPA 13, does not tell you which buildings are required to be sprinklered, which task is up to the building code or local ordinances. However, if the building is sprinklered (whether by mandate or voluntarily), it has to comply with NFPA 13. Note that the scope of

RE: Uprights in non combustible concealed space

Ask him to show you the requirement for that...Chapter and verse. The AHJ can' just make rules up as he decides he needs to. I know of no reason to leave them in place unless they become totally in accessable. The only thing I can imagine that would create that condition would be a hard

Ed – if this IS your last post, I want to thank you for contributing all these years since the onset of the SprinklerForum. Had NO idea you were so young – my Pops is 92, but wouldn’t be caught dead posting on the Forum. Of course, his only remaining interest in fire protection these days

RE: Uprights in non combustible concealed space

I could be wrong, but isn’t there something in IFC that states a fire protection system left in place needs to be compliant for the area? I’ve had inspectors interpret as you indicate. It’s the rationale that you can’t leave dead sprinkler pipe in the air. Now, I have had this same

Not really. The codes and standards determine the decision. This may be my last post. At the age of 95 I am starting to lose interest. Ed Vining 2770 Pleasant Hill Rd Apt 228 Pleasant Hill CA 95423 925-448-2159 fpe...@gmail.com On Thu, Jun 18, 2020 at 11:28 AM Cary Webber via Sprinklerforum <

RE: Uprights in non combustible concealed space

Agreed. You might request a reference to the code that is being enforced. I always say "how can I be sure I am doing it right until you tell me what the rule is? I would not want to accidentally fix it wrong." Matt From: Sprinklerforum On Behalf Of Richard Carr via Sprinklerforum Sent:

The AHJ should enforce the code not make it up, code does not prohibit the sprinklers to remain above the ceiling. Richard M. Carr, SET Project Manager/Design Diboco Fire Sprinklers, Inc. 325 Jackson Loop Road Flat Rock, NC 28731 rich...@diboco.com 828-696-3400

RE: Protecting A 500 Degree 12' x 10' Oven

NFPA 86 requires internal protection of certain classified ovens based on a study of the oven's use and contents. 9.1* General. A study shall be conducted to determine the need for fixed or portable fire protection systems for ovens, furnaces, or related equipment. 9.1.1 The determination of

RE: Uprights in non combustible concealed space

On the downside, if all areas above the ceilings are not protected, it may give a false sense of security. On the upside, more sprinklers are better, and even if not required they can act as detectors in the space. Bottom line is that the AHJ has ultimate decision making authority. Cary

Uprights in non combustible concealed space

We installed temporary upright Protection in a partially occupied building during a major renovation. We then came back and dropped pendent heads in the new ceiling. We left the uprights above the new ceiling. Fire inspector says we need to remove the uprights now. Is there a basis for removing

RE: Protecting A 500 Degree 12' x 10' Oven

Sounds like a dry system. has anyone looked into the issue of introducing a spray of cold water into a box that hot? Has the manufacturer given any advice on it? Also - would a fire inside the oven be any hotter than the oven's operation? What are they cooking in there? Are the walls of the

I've had an installation in service for 4-5 years now on an air force base with a similar setup and no issues to date, using those Tyco quartzoid sprinklers - 4 of them I believe - had to use a dry system to make it work. It was USACE approved. Spencer Tomlinson, PE Owner, Fire Protection
