That picture was being circulated a couple years ago, and the title call the gentleman "rednecks." aka American hillbillies, who we often like to make fun of. But I wasn't fooled, I recognized the the power strip as a european style. HA!
It's a staged photo. There's no heat or smoke from the hotplate, no sign of any food on or off the hotplate, no plates or the room to put the plates down and there is way too obvious a focus on the power cord situation.
I sort of suspect they would be fine actually. No one is completing the connection from line to ground. First person getting out of the pool get its big time though!
I dont know what the codes are else where but all outdoor outlets are GFI protected by law in the USA and have been by code for at least 15 plus years.
If you have a nut that wont cooperate just use a bee smoker or fire extinguisher and gas him. Its harmless but very effective. Lack of breath makes anyone compliant eventually.
If I had to deal with a dummy that climbed a high line pole I wouldn't climb up after him!
Its a mistake that gets too many good people killed every year just over some dumb ass that the world would be better off without if he only fries himself. Just like in the train video.
