It would take an enormous amount of copper sulfate to turn the water that green. Plus, there wasn't anything around to reduce the sulfate to sulfide. It was an oxidizing environment.

For as green as the water was, the fact that no one died from kidney failure (IIRC) leads me to believe it wasnt copper sulfate edit: actually i dont remember the toxic dose, so maybe im full of poo poo Slanderer fucked around with this message at 02:42 on Aug 19, 2016 |

The Lone Badger posted:Lethal for a human is about two grams. But severely diluted and they're not drinking copious amounts...seems like it'd be difficult to get that much? The copper sulfate makes sense for turning Lochte's hair blue (instead of green that pool water normally can). Chemistry isn't an exact science, guys.

Hey, I got rammed on one of those wheeled luges once, too. It was not too far from where I'm posting, on the Hallandsås ridge (which is also where a bunch of workers and cows got OSHAd by toxic sealant used during a tunnel bore in the nineties, but that's a different story), and I was about seven years old. My mother has always liked these insane death traps and decided to take me, my brother and our cousins on a ride on the wheeled luge track at Kungsbygget. I'm an enormous wimp, especially when it comes to speed, and was quite opposed to the idea, but my mother insisted that it's fun regardless of whether you enjoy riding wheeled luges, and that I could just use the brake lever, cleverly situated between the luger's thighs. After a bit of coercion I agreed - I was the last of us to ride and we were the only company there, so I figured I could just take it nice and slow throughout the track. Turned out I was slow enough that a speed demon lugemaster materialised at the track while I was riding and caught up with me towards the end. He slammed into me just after a big drop, and the surprise of the impact would have been enough to make me jump out of my skin even if the luge had been equipped with a safety belt to hold back my tiny form and save my crotch from being smashed by the brake lever. Good lord, that hurt. It was probably the worst pain I've ever experienced, but everything seemed intact. I was asked to join my family for wheeled luge rides another few times during my childhood, but that was enough for me. Today, about seventeen years later, I'm asexual and suffering from hormonal imbalance ever since those terms became meaningfully applicable to me, and while I don't know enough about the endocrine system to suggest a connection that would be funny as all hell my girlfriend is Legos fucked around with this message at 05:32 on Aug 19, 2016 |

This reminds me of an accident a few years back where an elevator repairman jumped out the interlocks (and some other parts of the safety circuit as well I believe) while he was troubleshooting an elevator at SUNY Downstate medical center in Brooklyn. Since the safety mechanisms were all bypassed, the elevator had the potential to move with the doors open. Naturally the hospital also failed to put up a sign or anything indicating the elevator was out of service/currently being repaired, so a woman went to get in and it took off at full speed while she was still halfway out. She ended up at the 8th floor with her leg trapped (up to the thigh I believe) in the tiny space between the cab and the floor; the fire department had to cut out the building floor just to get her out. Here's a short article about the incident on the elevator accident blog, along with the security cam footage of her getting into the elevator (which is horrifying but not graphic, if I recall correctly): http://www.elevatoraccident.net/severity/serious-injuries/2010/12/brooklyn-ny-woman-dragged-8-floors-leg-mangled-by-hospital-elevator/

Probably the same case with escalators, but I didn't bother looking since I'm scarred for life from that one episode of Rescue 911 I saw when I was ~10.

Any elevator video binge has to include the talk about elevator hacking, https://www.youtube.com/watch?v=ZUvGfuLlZus. Elevators are very safe if you're inside them. Being in the hoistway, above the cab, below the cab, or partially inside the cab are the potentially unsafe places to be if something goes wrong.

Access the elevator drive parameters and change the S-curve settings. This can result in a very fun ride!

I took a class on risk analysis and I chose elevators because I used to be afraid of them (and in buildings that are tall enough to feel how long the cables are, still am) and learned that most of the people who die because of elevators die by falling into the shaft, either while it is under construction or because they are rescuing someone and gently caress up or try to escape and gently caress up. It seems like if you manage to get into the elevator car you're pretty safe as long as you only try to leave through the door.
