Cell Phones in Blasting Zones?

I’m assuming that they ask you to shut off cell phones in blasting zones because they’re concerned that you may inadvertantly set off the charge.

Has this actually ever happened?


Well, I’ve been Googling for a while, and I can’t find anything about “oopsies” in construction zones–all I can find is Israel/Palestine bomb stuff, under “cell phone detonated” and “cellular phone detonated”.


So evidently they’re not joking, when they say “turn off your cell phone”.
