Biggest issue with HEF is that you'd have to have a way to contain the foam within the space. Since most of these structures are open, the HEF would just float out of the building.
Honestly of all the options Vortex might be one of the best choices, it doesn't require containment like gaseous systems, environmentally friendly, uses small quantities of water (minimize collapse potential). But it really needs some testing to be proven. Has good application for flammables and combustibles, not sure about how it would react against plastics but based on the mechanics and chemistry of the system, it would seem to have potential.

Even when boats are wrapped or covered, the covers burn off quickly enough, and it only takes one boat-load(ha ha) of water to bring a hot rack down. (bob kaputo and james lake hit on this topic at the conference last year) I liked the idea of a vortex system. I saw a pretty cool presentation about those this week. They hardly use any water and don't have trouble with obstructions. A high-expansion foam system would probably do the trick too... if you don't mind a huge-normous up front cost of installation. And yes, in my professional opinion, "huge-normous" is a legitimate description of the cost.

Your potential loss would be far less, and at least you'd be helping someone. If Scott is offering to help design this thing, take him up on it. I'd love to know what you all would end up doing. Now there would be some fodder for the forum. Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O.
