When the liquids are taken out of the cabinets, what is done with them? Is there any dispensing going on within the area where they are stored?
Storing them in a cabinet may not drive the design criteria but how and where they are used once taken outside the cabinet can certainly affect your criteria. You also need to know what size are these containers? Are they 1 gallon pails or 55 gallon drums? What classification of materials are they, class I flammables or Class III combustibles? Are these vented or non-vented cabinets? Another issue to contend with. If these are incidental volumes used in a lab where small quantities are removed and used then OH2 may be appropriate. All these things need to be analyzed before you determine the design criteria. Craig L.

Roisum, SET Sent: Wednesday, February 14, 2018 10:39 AM To: firstname.lastname@example.org Subject: Flammable and Combustible Liquid Storage [EXTERNAL] IFC 2012 Table 5003.1.1 gives the maximum allowable quantities of flammable and combustible liquids per control area. If the liquids are stored in approved cabinets you can increase the volume by 100%. I am trying to determine the proper sprinkler design for areas that contain flammable and combustible liquids that are stored in approved cabinets. NFPA 13, 2010 edition states that occupancies with moderate to substantial amounts of flammable or combustible liquids shall be designed to Extra Hazard Group 2 (5.4.2). However, I am confident that because the liquids are in cabinets that this space would not be designed to EH2, but I can't find any verbiage that explicitly says so. I believe Ordinary Hazard Group 2 is adequate but I need to document from the codes and standards my reasoning. Can anyone point me to a code or standard section that states that if flammable or combustible liquids are stored in approved cabinets that you basically don't have to account for their presence?...at least I believe that is the intent so please correct me if I am wrong.
