"It's not nice to fool (around with) Mother Nature" ;-)
The worst incident I ever had to contend with was a CATV head unit in an apartment house.
It's power transformer was the kind with a steel case, potted, with leads out a hole in the bottom.
When lightning hit it, the potting boiled, and blew out through the bottom hole, then solidified in the chassis.
I was just 16 at the time, working in my Dad's TV repair shop... so I was assigned the dirty duty :-(
