The original article was from Kodiak consulting.  Good thing I saved a copy. 
Thanks for the link to this one.

While I find traces of your article quoted, it seems to have vanished.
It lead me to this interesting article of 16 pages on electronic fires by a 
fire investigator.  There is a lot here for designers when it comes to 
preventing fires from your products.  I would never have dreamed of some of the 
ways that fires can start.

There's an excellent article out there on the web called "Low Voltage, the 
incompetent ignition source"  I highly recommend a read.
I dealt with a case like this a couple years ago.  Failed fet in an H bridge 
caused a fault which the brick SMPS picked up as a short, and went into 
"hiccup" mode on.
The energy delivered in "hiccup" mode was about 1W average, and that was 
enough, after several hours, to cause ignition and sustained flame on the PCB.
