While there have been many incidents, I have yet to see ANY real details, and nobody connected to these incidents has ever answered an email to get details.
If you dont know what really caused it you cant fix it.
I'm guessing this is just another knee jerk reaction. There werent any fires reported until the last year. The UK is also having a problem. (Based on news in a UK trade mag) but once again they are unresponsive too.
NY and the west coast can make all the rules they want, as long as they dont end up anywhere else UNTIL they reveal cause.
