ohhhh yeah, blasting and lightning don't mix well...at all...
When I was doing radio work up at Gray Rock (local limestone quarry), there was always radio silence near the blasting shack and then when they were preparing the pit for blasting, all cellphones and HTs checked in at the office, then all radio equipment in the vehicles were shut down, confirmed off before charges primed. Thunderstorms kept a lid on things, too...lol
