I don't know what is required. I wouldn't be too concerned about the electrical circuit itself. But being a very large metal object, don't know if grounding would make it more or less susceptible to lightning. Since it is on stone, I wouldn't consider the surface contact to be a good ground, If the container took a hit and your best ground is a 14 gauge wire or even a conduit...Poof!
Think the shop would get hit first this is almost below the grade next to the old barn wall. Hell I think the roof of the shop is only 10' above the road, maybe. Whats funny the hops trellis has been hit alot! Has a stainless cable system above it. sounds like some one shot a banjo when it gets hit!
Yeah, you’re probably right. That’s a metal roof. Aint it? Do metal roofs get grounded? Or does that actually increase the chance of it getting struck?
House has lighting rods, shop no. If you have a metal roof I would put rods up, not really expensive. Rain will ground them from what I have been told. TMM you have them?
If you read it on the internet, it's got to be true!
Yup U.S. Grant posted it so it is a trusted source.If you read it on the internet, it's got to be true!
Only metal I have is the shed roof. I do have a big antenna on the house. But it is tied to a ground rod. so in effect, it is the lightning rod for the house. But there are lots of taller things around including radio towers within a few hundred feet.
Better safe than sorry
Thanks Sparkey duley noted!
. He was coming back to the plant after unloading his mixer and one of those monsoonal summer desert storms fired up. His mixer was struck by lightning . He survived, mixer did not, but the impact re-broke his jaw 
It's doing it again. Post's are not showing in order. I saw later posts before this one. Pain in but when trying to follow. Oh well, could be worse. Ever try to follow a conversation on FB with them deciding what is 'most relevant'?
Wanna hear something hilarious… my brother comes up to me, says the tractor is sparking and won’t start… thinks the starter is dead. Go look at it, he’s got the jumper cables backwards…. Yeah I’d say it’d spark…Thanks Sparkey duley noted!
You stole it!
We also used ground rods on all of our containers at the farm. Each farm had one, they worked great for storage office space and break rooms. By same token we converted school buses into rolling lunch rooms complete with generator and porta pot. We did have considerable trouble with meth heads stealing out of them when parked.
That's really easy to go around. Buy only uncured pork. We get it from our local Ingles, but most stores carry it. I like Ingles, because they carry local mom and pop brands. The uncured doesn't have all the chemicals in it. Usually just water and salt and that's it. Just read the ingredients.
I felt guilty!!!
