- This video shows what could happen if a crane truck operator contacts a high-voltage power line with fatal results. It includes interviews from supervisors on pressures they face and the impact of an event like this one.
This educational video shows the dangers of working near overhead power lines when operating a crane truck and highlights how deadly an electrical shock can be.
This video is a helpful training tool and can be used in health and safety training for working around power lines and operating a crane truck in British Columbia.

I’ve seen this happen. I’ve seen boom trucks cause high tension lines to fall and start fires miles apart. I’ve seen booms and dump truck beds simply erased like a pencil drawing. Once an arc flash starts it can become its own conductor as the air around it becomes plasma. And yes, I’ve seem the incinerated remains of people caught by these arcs. DO NOT fuck with power lines. They kill and it’s excruciatingly painful all the time that you’re dying.
All the time you're dying? Its instantaneous if you make direct contact with any overhead or underground HV lines.
@@dewey7218 That's one of the misconceptions...at times if the current flowing through you is not immediately capable of knocking you unconscious, you are alive the whole time while suffocating and losing your vision (since the muscles in your eyes will probably also contract AND your eyes are...well, pretty watery organs...).
It's why the whole "Wood arc burning" trend using microwave oven transformers is such a deadly one right now...people see a video from some idiot who might also have no idea what he or she is doing and copy it, only to then experience 3,2 kV passing through them.
Some people have lived through this ordeal after it went wrong, experiencing how they were in a locked, upright position with their hands firmly pressed against their chest, unable to speak or do anything until someone who found them in time was able to switch of power.
oh wow all that trouble over like 16 bundles of shingles
I've seen a video of this actually happening to 4 men at once... One of the worst things I've ever seen. Don't screw around with power lines under any circumstances. It's a horrible way to die and it's not pretty either!
I remember that one. tragic.
I remember it also, terrible situation with a movable scaffolding.
I screw around with them on a daily basis, just gotta be smart
*"YOU ARE GROUNDED, MISTER!!!!"*
I guess that's yet one more reason to stand clear of the machine.....
Shocking video, brilliantly acted. Cheers!
This video implies that the fellow operating the crane watched as he put it right into the power line.
That's not an accident - that's a suicide.
He could just have bad depth perception
Typically, it's very difficult to spot the distance between a powerline and something like a crane. Maybe not in the way it was done here, but if the operator would've been on the other side, it's one of the many many reasons why these accidents are depicted this way.
During safety training for a forklift my brother had many students gasp at the idiotic examples of unsafe work practices used in the training, at which the trainer said "You are all laughing, but the mere fact these examples are in here, is because people tried them and they injured themselves bad or died."
I found it strange that he put one foot firmly on the metal stablizer and the other on the ground. This does not look like something that's normal. So yeah, suicide
"You are grounded until you learn to conduct yourself properly."
"FATALITY"
Common sense is the cure for most accidents .
Wtf? Someone needs to finish putting those materials on the roof!
TheAlfieobanz you are fucking funny
Well it aint happening today
Works canceled
I've been to many places in europe where there are no power lines overhead. Maybe Americans should start putting those heavy power lines underground in special pipping to prevent this kind of deadly accidents from happing. Just saying.
There are equally tragic accidents from striking underground wires/utilities when excavating and digging unfortunately...
Cost is a factor. It costs a fair amount to bury power lines, especially in already cluttered streets. Most people just don't understand how much infrastructure is already beneath there feet.
In Europe...
Lee Abraham it’s happening. The problem is the vast amount of lines capable of causing this. That’s a lot of linear feet to bury.
That’s British Columbia, Canada
WTH everybody knows that you don't get in a fist fight with heavy machinery while it's caught in the power line😡🤔👌
Amazing acting 👏🏽
So, will be continue??
Building is on the opposite side wth was he doing
Probably thinking of keeping the rest of the path clear for other trucks delivering equipment and putting it next to it as a result. Might look stupid, but not uncommon to see building materials stacked up in a line like this in my country, and I would suspect it to be not that much different in other ones as well.
But in another video he can't die!
accidentally the whole thing
How the fuck would you get electrocuted standing on the plywood pad next to the truck stabilizer? Your boots have rubber soles, it's obviously dry in this scenario. Where was the contact? Also lift trucks and boom lifts have ground connections so this exact thing doesn't happen.
juan gonzalez your rubber soles and the plywood won’t protect you in the least at the voltage in those lines. They are good for around 600 volts. The voltage in those lines are an order of magnitude or more greater than that. Rubber and wood are not electricity proof. They are only electricity resistant and their resistance to the flow of electricity will collapse if the voltage is great enough.
step potential. unless his safety boots are EV rated, he has created a difference of voltage potential between his two legs, one of which is right next to the stabilizer, the other standing on soil. also good of you to know about ground connections on all lift trucks. I know line crews that don't use this device on their trucks; only when putting a grounding cluster on deenergized primary lines.
Rubber soles and dry weather: High voltage exceeding the 1-2kV mark typically doesn't care. If you happen to be a better path (and to come back to the "dry" factor, your body is 2/3rd made of water...so...) the current will happily jump from the support structure of the truck to you.
It's sort of the same as why you are taught not to seek shelter under a tree in a thunderstorm: if the lightning only hits it without making it explode like a bomb, it will almost always cause you to suffer a serious (and probably fatal) shock due to the voltage difference passing through you, especially if you happened to have the lightning jump from the tree to you, or if your legs were apart from each other, causing a step potential in the ground from the tree to your first foot and the second, which can already be hundreds of volts.
And no, a truck will typically not have a grounding rod jammed into the ground to reach 0V potential, it would take to much time, there's a risk of jamming the rod right through other cabling or piping, and even if a truck needs to be at the same potential as something else, it's typically not this type of truck, but the kind delivering chemicals known to induce static electricity upon getting pumped over or simply due to the stuff sloshing around in the tank. The chemical factories using that ingredient will then have their piping supplied with a grounding connection the driver needs to connect his truck to.
But even if a grounding rod would be present: there's still the possibility of step potential directly around the rod causing danger. If the grounding rod would need to be driven down exceptionally deep because it otherwise can't reach 0V potential there's also the risk that this is not done properly, and the truck with all it's tires and the pads on the support structure to keep it leveled makes for a much better contact (electricity taking the path of least resistance, remember?).
Once again Charles Darwin is proven correct...
Aren't power lines insulated
+NeXTSTORMING Yes, but not in the way you think.
I don't know about Canada, but typical Voltages for a distribution grid are 10-25kV. Insulating a cable to the touch at those voltages is ridiculously impractical for overhead transmission; the cables would easily have 3-5 times the diameter then the once in this video and would of course be much heavier.
They are shielded enough to prevent arching between them in air, but if you come very close to or touch them with a good conductor (like a metal crane), you dun goofed.
grmasdfII Also, it is already very costly to put up power lines, and insulating them all would be much more expensive.
