Codes & Standards Discussion Forum 

Welcome to the ICC Codes & Standards Discussion Forum

The Code Council has revisited how best to provide an online, professional Discussion Forum and area within the website that has a sense of community – where Members and nonmembers can provide input and exchange ideas with their peers in the industry. The new Codes & Standards Discussion Forum does just that, as it allows Registered Website Users and ICC Members to discuss the I-Codes in an online community.

Look in NFPA 58 (IFC referenced standard)for portable containers indoors. It provides some very clear guidance based on the use.

Sorry, I don''t a copy in front of me to quote the section for you.

doesn''t sound like a very good idea... there might be enough propane to throw that tenant into some sort of "H" occupancy.

Don''t know about California amendments which could be more restricitive, but the 1997 UFC would allow 30 gallons in a sprinklered building before it had to become an H occupancy. Or you could install control areas then each control area would be limited to 30 gallons. Also, you must take into consideration all the other hazardous materials in the rest of the occupancies in the building and add then together to get the requirement for the entire building. One can separate a building into two buidlings with the proper construction.

Then there would certainly be other requirements such as ventilation, explosion proof electrical, etc. Check also NFPA 58 as already suggested. Inside storage of propane is definately not a good idea. You should be talking to the building and fire officials.

The problem with the MAQ tables that Greg quoted is they are not consistent with the requirements of NFPA 58 for LPG. For the conditions described, its not permitted by NFPA 58. In fact, it prohibited. Generally speaking, the NFPA 58 committee has taken a very good stance on this given the potential energy of propane.

Propane can be [i]used[/i]inside of building but storage is generally prohibited unless it is a mercantile occupancy. Even then, one is only limited to 200 pounds of propane capacity and each cylinder is limited to 2.5 pounds propane capacity. These are generally disposable cylinders.

Move the propane in storage outside. Check NFPA 58 because the standard does allow cylinders inside that is attached to equipment when it is not in use.

Scott is correct. Howver the IFC says almost the same thing. See below. 2006 IFC Section 3809.9 states:

3809.9 Storage within buildings accessible to the public. Department of Transportation (DOTn) specification cylinders with maximum water capacity of 2.5 pounds used in completely self-contained hand torches and similar applications are allowed to be stored or displayed in a building accessible to the public. The quantity of LP-gas shall not exceed 200 pounds except as provided in Section 3809.11.

Notice the use of the word buildings vs. occupancies within a multi-tenent building.

I do agree that the IFC and NFPA 58 need to be better coordinated, however the IFC provides, in Section 102.6, that when the provisions of the code and a reference standard conflict that the provisions of the code shall apply.

It is typically held that the most restricitive requirement shall supercede as well. The decision is up to the code official.

In your situation I think that the provisions of 3809.9 would apply. Sorry for the first misdirction.

Thank you all for your comments, they were all interesting and most of them we discussed between the department and our building official. The fire officials finally contacted us, and as we suspected, this type and quantity of storage of propane is NOT allowed indoors. The designer will be looking for an outdoor location for this storage, which may work for them.
Thank you again for all of the comments.
