Does anyone know of an instance of a plastic-cased, LED exit sign with battery backup failing and catching fire?
Thanks

I've seen plenty of melted ones from back in the day when I would get all the fire reports and go out and do inspections but I've never heard of nor seen one where it was the cause & origin of the fire.
Just curious: Is this an exit sign/ emergency light combo? Or just an exit sign?
Picture(s)?
Just a simple exit sign: 120-277VAC input, small battery, LEDs, no provision for supplying emergency lighting heads, no built-in emergency lighting heads.
I'll see if I can get a picture or two.
Report suggests it was the source of ignition. I'm trying to figure out if a failure internal to the sign itself (rather than a wiring problem of the 120VAC supply) could have developed sufficient heat to be the source.
Great find!

I don't but the concept seems real considering what is happening with poor ventilation and batteries overheating in the hoverboards.
I realize the hoverboards are Lion and the exit sing is probably lead acid, but both can go into thermal runaway.
One investigator said the fire origin was in an in-wall box. Second investigator disagreed since the box contained a 24V pull station powered from a limited power fire alarm circuit. They then went to the building next door (which also burned) (separated from this building by about 2 feet and both originally covered with vinyl siding). They found a fire origin at floor level opposide the wall - space - wall of the pull station, and evidence of accellerant. That building was a half-way house for prisoners on the way to being released. One of the girls had been notified that she had violated some rule and was being sent back to lockup. Our case closed.
