My thoughts - cooking oil is a class IIIB combustible liquid; the model building codes would limit to not more than 13,200 gallons before changing to an H use group. If the containers are metal, then no issue. If they are plastic (prohibited for class I flammables and class II and IIIA combustible liquids), then more consideration should be given to density, particularly if the containers were to remain exposed/unprotected from persons or adjacent vehicles (think car fire exposure, etc.).

As for the existing system, the garage was designed for an ordinary group 1 and is protected with a dry system. The initial fear from my service side was that this would require the system to be re-calculated for an extra hazard (and thus, completely reworked based upon the density). My hope is that an enclosure in accordance with NFPA would be sufficient but I am still trying to gather more information before I approach the AHJ. Hope this helps. Thanks for all of the ideas so far... -Sean -----Original Message----- From: Prahl, Craig/GVL <[email protected]> Sent: Wednesday, February 26, 2020 9:21 AM To: [email protected] Cc: Sean Lockyer <[email protected]> Subject: RE: Flammable liquid tanks in a garage What kind of flammable liquid would be used in a restaurant? Liquid propane? And you say the garage area has sprinkler protection? What density? Wet or dry?

Question: What does this do to the hazard classification in the garage ? Would the owner need to built an NFPA 30 type enclosure around the tanks ? A bit of a grey area and not really sure how to proceed. Never seen this before. What says everyone ? Sean Lockyer Project Designer 6817 N.
