I am really looking forward to having this contractor's rear end for breakfast tomorrow since I would be dead right now if this crane hadn't been welding itself to the floor by the time I went to switch it on.

Three-phase that was what I thought too after two days of intermittently plugging it in and troubleshooting the hoist. But no, the busbar fuses never blew and I kept unplugging it, looking for switches or wires rubbing inside the panels, nothing. Then I walked away to look for a mechanical drawing, believing I had ruled out any possibility of an electrical problem and returned to a wide eyed engineer asking "is this nut supposed to be smoking? Have you guys been welding over here?"

Not on purpose bro.

E: and yes, the ground teminal on that plug is painted bright green on the back how the gently caress did someone gently caress that up

The safety ground wire is always yellow AND green. When you have power wires you never see a another striped or dual-color wire used. (However this is really common for small control signal wires.) Plus "black-on-brass" I've been told.

Generally this is what I've seen:
Black, red, blue (hot)
White (neutral)
Green/yellow (earth)

Brown, orange, yellow (hot)
Gray (neutral)
Green/yellow (earth)

The neutrals have a different color so if you have a box with 120/208 and 277/480 you don't get the neutrals mixed up or tied together.

There's also another color for the high-leg ("bastard leg") on a center-tap grounded delta because that wire has a higher than normal voltage to ground.

Notice the combat medic being a split second away from being squished by a shunter locomotive, moments before it derails as well and strikes the derailed railbus.

https://en.wikipedia.org/wiki/Rudine_derailment

The wikipedia article fails to mention that the driver of the railbus, after noticing that the locomotive has lost all traction and has turned into a bobsled for all practical purposes, activated the emergency brake but the train actively refused to drop sand that would have prevented the disaster due to faulty software in the locomotive.

It also fails to mention that the defective flame retardant liquid was cheaper than the standard stuff and that someone pocketed the not-quite-insignificant difference.

Moral of the story: if you're traveling in Croatia, just take the loving bus.

Are there about how we always run directly away from something because if you turn and run perpendicular, the tiger is going to eat you because of cutting the corner?

Many of the folks who were either shut out or priced out ($1 tickets) found a perch to watch the game for free. Just across the street from the stadium was the brand-new San Francisco and Pacific Glass Works building, and 400 to 500 boys and men climbed onto the building’s metal roof, nearly five stories high, for a splendid view of the game.

About 20 minutes after kickoff, the roof collapsed — “Sprung open like a gallows trap,” one survivor said — raining about half the boys and men down onto the blazing-hot, brick cover of a vat filled with 15 tons of burbling molten glass.

“Plunge to Their Death on a White Hot Furnace,” The Chronicle’s front-page headline read.

The Evening News in San Jose went with “Sizzling, Shrieking Human Mass.”

Man dissolves in acidic water after he falls into a Yellowstone hot spring

A trip to one of the nation's natural wonders ended in a unnatural tragedy.

A 23-year-old Oregon man essentially dissolved inside a hot spring at Yellowstone National Park in Wyoming after he accidentally fell into it.
The bizarre incident happened back in June, when Colin Nathaniel Scott went to the park with his sister to find a place to "hot pot."

According to a recently released report from park officials, Scott and his sister went to an unauthorized area near the Norris Geyser.

"They were specifically moving in that area for a place that they could potentially get into and soak," Deputy Chief Ranger Lorant Veress told CNN affiliate KULR. "I think they call it hot potting."

Scott had reached down to check the temperature of a spring when he slipped and fell into it. Rescuers later found Scott's body inside the pool, but couldn't retrieve it because of a lighting storm in the area. When they came back the next day, no remains were found beneath the spring's churning, acidic waters.

"In a very short order, there was a significant amount of dissolving," Veress said.

The parks' geyers and springs are acidic because they are fed by thermal water deep underground that picks up sulfuric acid as it rises to the surface. The sulfuric acid is produced by microorganisms that break down hydrogen sulfide in rocks and soil.

Scott's sister was recording on her cell phone when he fell in, but the park service won't release the video.

Veress stressed the importance for park visitors to obey all warning signs.

"Because (Yellowstone) is wild and it hasn't been overly altered by people to make things a whole lot safer, it's got dangers," he said. "And a place like Yellowstone, which is set aside because of the incredible geothermal resources that are here, all the more so."

How did so many people survive? Or is that not counting people who slowly died of fatal burns later?

400-500 people were on the roof. "About half" of them fell (so 200-250)on the factory floor. The factory floor had a furnace on it, but the furnace obviously covers much less than the total floor space.

Perhaps you were imagining a factory building consisting of nothing but a giant furnace stuffed snugly between four walls. That would be very silly.

22 total dead after a couple days. I'm guessing the entire lot of 400 or 500 didn't land on the hot spot.
