Electricity, it don’t play.
I used to work near a sub-station. People would occasionally try to steal cables… once all they found was a hand and a foot.
I’m a paramedic. We had a DOA once of a guy that got electrocuted trying to steal metals from an electrical panel. This wasnt a residential one either, but from an industrial building.
High voltage guy here, my answer is “steam.”
I’ve worked up to 345,000; you definitely need to be on the ball but it can be done safely.
I would never willingly work around steam systems.
We had one plant with 48″ steam pipes under god knows how many hundreds of pounds and the extent of the safety training was “Always know where your exits are and if you hear water hammer run for your life.”
Garage door springs
Garage door springs. Seriously. Unless you know what you’re doing, you’ll die.
However, if you DO have to fuck with them, there’s a few redneck methods of getting ’em gone that are REALLY effective.
My dad’s got a cabin way out in the woods, and one day we found a big Hornets’ nest just under a window, buzzing with sinister intent. Since the nest was about 15 feet in the air, the usual can of raid wasn’t going to cut it. My dad’s solution was to slam 3 beers before pulling out his wet/dry vac, and duct taping it to a spare piece of ~10ft metal piping (the cabin was in the middle of renovations to get running water, so construction material was all over the place). Then, he took the piece of pipe and positioned it using sawhorses so that the opening was just below the entrance of the hive. And then he turned on the vacuum.
The combined noise and vibration of the vacuum was enough to cause the entire hive to disgorge its angry occupants, who would buzz around around for about half a second before getting THWUPPED down the tube and battered around in the belly of the vacuum cleaner.
Now, unfortunately, this isn’t enough to kill them, which we learned after pulling the top of the vacuum cleaner and seeing a heaving, surging mass of chitin and malice attempting a mad dash for the sunlight. So, what do you do with a plastic barrel full of Hornets? Well, if you’re a 50 year old redneck with a thirst for vengeance, you pull out your trusty duct tape and Macgyver your F-150’s exhaust port to the end of the vacuum cleaner, and then roll enough coal to smoke every last sonuvabitch into a stupor. Then, you take the entire wet dry vac, and dump it into a nearby bonfire as a final “fuck you”.
So yeah, Hornets may be bad, but sometimes the absolute jankiest way to get rid of them ends up being exactly the one you needed.
