Dan,
The classification of margarine was based on testing of margarine in
plastic tubs in cardboard cartons in the FM fire products collector.
Something a lot of people forget is that free-burn heat realease rate
of a commodity and the sprinkler density required to control a fire that
starts in it are not always directly related. It turns out that it
doesn't take much to keep the packaging from getting the oil margarine
burning. If you melted the margarine, let it collect in a pool, ignited
it (like what happened in the tunnel) and then tried to control it with
sprinklers, it would be an entirely different story, but it takes a lot
of heat to melt enough margarine and drive off the high water content to
get an oil fire going..
Based on the test, I can't see any reason that ESFRs wouldn't work.
Joe
