CFC Ch. 34 Flammable and Combustible Liquids storage containers

[arion]

Hi,

Are there any special storage containers or protected enclosed cabinets that can segregate combustible liquids, particularly Class I liquids, such that we can treat the separation of high piled storage area as if it were a 1-hour fire barrier (per CFC Section 2306.3.2.1)? My objective is to segregate the quantities of Class I liquids so that my client can put more in his store and treat them as unique high piled storage areas.

Thanks.

You can construct control areas. See the definition in Chapter 27.

What quantity are you looking at??

What kind if business

Accessible to public??

The building is nonpublic-accessible. It's a small warehouse that sells roof lacquers and other roofing materials. Most products are Class IIIA/B liquids, but there are sizable amounts of Class II and noticeable Class IA/B amounts. If Table 2703.1.1(1) says they can only store 30 gal of Class 1A flammable liquids, and notes c and d apply, then I believe that means I can store 120 gal in the HPS area ( 30 gal + 100% + 100%). They have more than 120 gal but understand that they will be forced to reduce to that if they have to. However, I was asking to see if there was a creative way to allow for more that remains legal.

HOWEVER, here's the kicker: The client only has .33/3064 design density/area. Because of this, I have limited options in Table 3404.3.6.3(5), which means that he can't even get his products on racks-- he will have to resort to palletize and floor stack 3404.3.6.3(4) them if he wants these items or remove all Class IA liquids and install in-racks.

The only alternative seems to be stookey's recommendation of adding a control area, but I have never done that. I've never seen one first hand, so would not know how to instruct that it be created.

well you can hire Stookey for a slight fee

can not speak to sprinkler design but,

CONTROL AREA. Spaces within a building that are enclosed
and bounded by exterior walls, fire walls, fire barriers
and roofs, or a combination thereof, where quantities of hazardous materials not exceeding the maximum allowable quanties per control area are stored, dispensed, used or handled.


414.2 Control areas. Control areas shall be those spaces
within a building where quantities of hazardous materials not
exceeding the maximum quantities allowed by this code are
stored, dispensed, used or handled.
414.2.1 Construction requirements. Control areas shall
be separated from each other by not less than a 1-hour fire
barrier constructed in accordance with Chapter 7 of the international building code.
