I would be far far far far far more concerned with dry lightning strikes personally
one year in Tas, I had the experience of being on watch. All was calm, all was quiet, the birdies were singing and the sky was clear - then, out of nowhere came a lightning strike.
can't recall the time - maybe ? 8 or 9 in the morning. Within an hour there was ash falling from the sky.
By the next day there was something like 60 fires across the state - whereas there had been zero prior to the dry storms.
Dry lightning reaches places that humans cannot - and that includes firefighters.
