Of course, the news gets it wrong and claims people collapsed 'due to toxic fumes caused by a mixture of liquid nitrogen and pool chlorine'. https://www.youtube.com/watch?v=DM6_pUE-3Pg

Well, the paint was safe to use, but the solvent used to clean the paint gear released flammable vapors. 5 workers died when they were trapped behind their cleaning gear after it caught fire. The video does a good job of laying out the many many ways this was avoidable.

CSB videos are both thoroughly enlightening and thoroughly depressing at the same time. The depressing part doubly so when you do a little followup and realize that very few of their recommendations are followed by regulatory boards or private enterprise.

Overwined posted:I understand about the water not being off, but why was the power on? The breaker box for each apartment was in the utility room where the washer and dryer are anyway. It makes no sense. Leaks aren't always immediately apparent, especially if they happen in a wall. Say he had the power off while actually doing repairs. Dude thinks he's fixed it, turns water back on and walks away meanwhile there's water pissing everywhere. Also, those higher voltage outlets should be in a place where water can't easily flood them to begin with, and even if they do flood then the breakers should have tripped before a fire broke out. It sounds like there were multiple things wrong at once.

35 years ago on the night of September 18th at around 6:30 PM, a worker refueling a Titan II missile outside Damascus, Arkansas dropped a 25lb socket wrench onto the missile, which punctured the fuel tank. About 9 hours later it blew up, two airmen sent to check on the condition of the evacuated silo were severely injured, one died from injuries and exposure to the fuel oxidizer, while 21 other people were injured in the explosion or by exposure to the fuel/oxidizer. The 750 ton silo door was launched around 600 feet while the 9 megaton nuclear warhead ended up in a ditch 100 feet past the entry gate. (the lozenge shaped thing in the below image is a propane tank IIRC) The book "Command and Control" goes into great detail about the accident, other accidents, and nuclear weapon safety.

Workers started renovating my apartment building's roof today. Nothing says OSHA like five people walking on a 45-degrees sloped roof on top of a six-storey building without harnesses or safety ropes. (They did put safety nets around the edges of the roof, but those look extremely flimsy.)

loving lol at these people with cryogens. I used to pour buckets of liquid nitrogen a plunge my hand to the bottom. That said, once I put a copper rod in liquid nitrogen then pressed it to my arm to see if it hurt. It didn't. I had a scar for a few years.

I got one on my elbow from leaning against a metal flange that was in contact with a bunch of liquid nitrogen spewing out of a vent for just a second and it stuck around as this maroon colored burn for a while. Didn't ever hurt it was just a kind of thicker scab for a while until the skin all regrew like normal.

mine was pure white surrounded by angry red. I held that rod on there for ages just to see if a cold burn would hurt. I was a dumb. Thankfully I was briefed properly on the dangers and handling of cryogenic containers and never did anything so blase with them. Hell, the old school tech guys told me about getting snipers in to shoot off ice plugs cos they were too dangerous to go near.

Some summer work I was doing in highschool involved dewars of liquid nitrogen. The engineer I was working with absentmindedly grabbed a dowel, froze it, and began freezing warts off his fingers before he realized the example he was setting and mentioned "you probably shouldn't ever do this, but you know, it works so well..."Phanatic posted:Yep. It's also the reason why you pass out so fast. You can hold your breath for a while without passing out (you'll almost certainly surrender to the impulse to breathe before you pass out, but free divers can do it for upwards of 10 minutes), but in that case your blood isn't outgassing the O2 when it passes back through your lungs, and as the partial pressure of O2 in your blood decreases then more O2 diffuses in from the breath you're holding. But if you're actively breathing an N2 atmosphere, then the PPO2 of that gas is zero, so when your blood hits your lungs the O2 diffuses right back out, like if you were breathing vacuum, so you've got maybe 10 seconds of useful consciousness, tops, and then it's lights out.

This reminds me of some stories I read on the NIOSH FACE database on deadly accidents while disassembling lattice boom cranes. See, lattice booms aren't like telescoping booms. With a telescoping boom crane, you just retract the boom and hook it to something to keep it steady (like the Terex T340 our company uses for practical exams has a big D-ring on the front for the hook, while the Terex BT4700 boom truck we own just has a loop of rope at the rear to do the same job). With a lattice boom, however, the boom actually has to be assembled and disassembled from pieces. During a good disassembly, the pieces of the boom are supported by attached wires to hold them up when they're disconnected. But you need to remember to actually support them. Cue more than one worker (especially ones who don't speak English very well in the US like Latino laborers) not only pounding out the big pins holding stuff together with a sledgehammer when they're not supported, but standing underneath the boom to do so. The last pin gets knocked out, the boom collapses like a big KNEX structure, and the poor guy underneath ends up folded in half the wrong way.

The poorly-named documentary "Nuclear 911" talks about reported Broken Arrow incidents (Also it's narrated by Adam West for some inexplicable reason): https://www.youtube.com/watch?v=RpFSefIsZkc The USA has dropped a lot of nukes by accident. They've never had any full detonations from these accidents however in almost all of them the first-stage conventional high-explosive detonated resulting in large amounts of property damage and, in some incidents, loss of life.
