He trips (or dives) as he's running, you can see him start to fall over before the truck passes over him.

The underride guard tends to just be cantilevered outboard of the vertical attachment bars - the only thing standing between you and decapitation is the wall thickness of a box section.

The one that made me mad was the Hyundai unmodified trailer where, presumably to save $2, they had no gusseting on any of the underride bar and it was effectively cosmetic.

There's also that guard rail lawsuit about the company whose altered design ended up impaling people instead of slowing their crashing car down safely

I didn't realize for the smaller arcs there was more energy in the resulting clothing fire than the arc itself, but that makes a lot of sense. I'll need to send this to the guys at work. :stare::hf::science:

My PPE is Level 2, 8 calories. Got the balaclava, rated hardhat and the greenish-blue arc rated face shield. There are other electricians who have Level 3 and Level 4 equipment, plus things like hot sticks.

Just curious, what kind of work/voltages do you use for that level of ppe?

I work in substations (rail) and I work from 120v DC to 66000v AC. Yet my PPE is 185gsm cotton drill. We however focus on engineering controls/isolations. Never work live (except maybe to 120v dc for testing purposes).

I think the weirdest part of this image is looking at the underride guard behind the apparently-untouched back wheel. Either there's some damage there I'm not seeing, the underride guard doesn't go all the way across the back of the truck, or the physics of crashes are :catdrugs:

I'm reading it as the bar that was parallel to the back of the truck got sheared, but the more reinforced supports stuck around and cut through fiberglass like butter.

It's from the adaption of The Ugly American, something that the clip neglects to mention entirely.

The stuntman was Paul Baxley, who went on to be William Shatner's stunt double and the stunt director for The Dukes of Hazard.

I thought an inverted plug meant the plus was controlled by a switch on the wall. That way you could always tell which plug you were supposed to plug lamps into.

That's consistently been the case in every house I've ever lived in.

You've consistently lived in houses that were built or owned by someone who actually gave a poo poo. With the exception of my parents' house, every house I've ever lived in has had all the outlets installed ground-on-bottom, with the lamp switch outlets scattered totally at random, and also with the circuits laid out in totally random fashion.

The townhouse I live in now has the master and downstairs half bath on one circuit, with a GFCI in the half bath downstairs. Plug something in that trips it? You get to walk down the stairs to reset it! (I understand that a single GFCI is fine, and meets code, but it really should have been installed in the master bathroom, where people actually plug things in, and not the loving half-bath.) Plug too much in? You not only trip the breaker for those two bathrooms, as it should be, but it kills two outlets, on two different outlet plates in the living room, as well. :wtc:

They also installed an interior GFCI outlet on my outdoor outlet box, which is daisy chained to the garage. They didn't properly ground the circuit anything in the entire loving house, so whenever the garage door opener would run, it would trip the GFCI.

And this place has a BETTER electrical system than some I've seen.

Now with less breakage.

Is this the point where I bring up the IT system typically used in Norway? The last mile of power is three-phase at 230V between the phases, ~130V to ground. There's no Neutral and no central Ground, so a typical house has a local ground and gets three live phases at the intake. A socket has two live phases (so 230V) and hopefully ground, in a non-oriented Schuko socket. As connectors go, it's not quite so battleship-solid as the UK one, but much chunkier than the US ones. A proper schuko socket is also recessed enough that the pins don't make contact until they're no longer accidentally reachable.

We're apparently slowly moving to a TN net more like the rest of Europe, where the last mile is 400V between the phases, 230V to a combined ground+neutral, and you get four wires to the house; splitting the ground/neutral out at the intake box. More wires, but less risk of dodgy local grounds, and the higher voltage lets you use cheaper cable.

Isn't that weird-rear end system in use because of the tolerance to trees falling on the power lines? The backwoods of Norway being even less accessible than those of Sweden and Finland, with this setup there's no need to worry about ground faults caused by trees hanging off the lines since they are floating relative to the ground.

A lot of it is 120/208 to 480Vac. Highest I've troubleshot live was around 800Vac, highest I've worked around (not touching) was 4160V.

125V DC is nasty because people will use a non-contact tester, and it won't show dangerous DC voltages, only AC.

Something similar happened to one of my mother's friends from back in Detroit. As she was driving down one of the X Mile Roads, a low convertible went under a tractor trailer. The driver's head found itself lodged in her windshield wipers, staring at her.

She already had a rather fragile mental state when that occurred.

IIHS - Most underride guards fail to stop deadly crashes / long video /

Setting up, running those crashes, and then picking apart the car and the high-speed to look at and evaluate the design looks like an extremely awesome job. Still, some of those impacts are BRUTAL. :gonk:

Do they use supercomputers nowadays more to do crash testing (finite element analysis or whatever) in a computer instead of using actual vehicles? (I think that might be used more in the design phase, and then the crashing verifies that the simulation is acceptably accurate.) At least they were wrecking Malibus instead of destroying good cars.

I think real cars are pretty much necessary for reliable testing. Even a supercomputer can't account for every single variable in a real crash.

Exactly how are cars sourced for crash tests? Do car makers send a certain percentage of models for sacrifice or are old and junky cars donated?

I think it is a certain percentage of new frames with only the necessary parts. I don't think old cars wouldn't make for very good test material because use might make them inconsistent.

I know the reason the Porsche 959 never made it (officially) to the US is that Porsche didn't want to give 2-3 cars for the crash test rating. Hence the car was never approved to be sold on US soil.

It seems makers do have to pony up some cars for the test ratings, but I'm sure for all older comparisons and other tests they source their cars from other means such as a junkers and other private sales.

DC also locks you up, making it even harder to pry people away from whatever is electrocuting them. AC will make you spasm, which is slightly less bad, but still very bad.

Back in grammar school, our science teacher basically made this comment followed with the threat of having to do a flying drop kick to dislodge whichever dumb kid managed to start frying themselves. Coming from a 6 foot, heavy set lady in her early 50s means that a lot of the pre-teens found the idea of this happening super funny. Thankfully it was all just a legend and something that never had to happen.

Legend in what way? You definitely need enough force to break the connection between power-souce <-> person touching.
If you try to grab them to pull them away you just spasm/lock up together. A wooden broom handle or a 4by4 can help if you can't dropkick.


Oh, and DC is also very, very nasty because electrolysis will happen in your body and you can die way after getting shocked because it hosed up your blood. See a doctor.
