Well, they sanded the plates to shape, then washed, polished and painted them. The plates were made of Eternit, btw. According to the local health authority there was no asbestos found in or around the area where they worked so they seem to be thinking that the kids didn't get exposed, and the health service is saying the health risk to the kids is low. The parents are...disagreeing, especially the guy with his own asbestos-handling licenced construction company. I know pretty much nothing about asbestos exposure but the health service here is generally competent.

They're probably fine, asbestos isn't like radioactive or something, it's harmful when you cut it up and inhale the super tiny fibers.

Yes, it's like a lava lamp.

The etiology of mesothelioma isn't as clear-cut as that. It appears that you can get the disease from years of working with asbestos (e.g. a miner), or from years of just being in an environment where it's in the air (e.g. an auto garage up to the 1980s), or from a single large acute exposure (being caught in a collapsing building). The time to onset is usually multiple decades as well, so the causal agent often isn't even identifiable. And then there are some people with high exposure who never do develop the disease -- either because they just weren't going to get it, or because it took so long to develop that something else killed them before it became a problem. Pretty much the only thing that's certain is that if you work around asbestos and smoke cigarettes, you will die of lung cancer of one kind or another.

So the Canadian government decided to offer some compensation to some people this year after this happened (note: it is a sad story):quote:The accident happened when 137 teenagers were given dummy explosive devices during a supervised class at Canadian Forces Base Valcartier on July 30, 1974. It's worth noting the incident drove to changes in the way dummy ammunition is handled such as painting it gold with the big words DUMMY painted on it, as opposed to having it look exactly like the real thing. So I guess that's good. http://www.cbc.ca/news/politics/cadets-grenade-accident-compensation-1.3746700

CADPAT posted:So the Canadian government decided to offer some compensation to some people this year after this happened (note: it is a sad story): This brings me back to remembering a string of bombings in my home town back in the 90s. Basically 2 guys got their hands on a bunch of grenades and plastic explosives and proceeded to chuck them out of their car around town. I remember one going off on my street and my Viet Nam vet dad jumping up saying"that sounded like incoming!" Our neighbors weren't hurt, and just got a bunch of shrapnel embedded in their aluminum siding. Here's the OSHA part: a citizen found a rusty unexploded grenade on the street, picked it up, placed it on top of a fire hydrant, and called the police. When the officer arrived they found what was indeed a live unexploded grenade and decided that the proper method of EOD would be to drive it to the highschool soccer field for the bomb squad to take care of, and proceeded to drive down the street with his window down holding the grenade outside the vehicle in case it exploded. Luckily it didn't explode on the ride over, and the bomb squad was able to detonate it in the field. As an aside, my dad was the airbase librarian in Nam, and had more of an acedamic understanding of what incoming sounded like. My social studies teacher was a combat veteran, however, and already pretty twitchy. When the explosives went off outside he hit the floor shouting and ended up leaving for the day afterwards... This was 1993, and MAD UNKNOWN BOMBERS just ended up being a side note in the local nightly news.

Once it's cooled off I assume you hammer off any big chunks to throw away as solid waste and wash away the residue if needed. It wasn't any sort of sodium salt or compound. Just pure sodium metal. zedprime posted:Making custom gaskets is totally a thing for simple polymer and metal gasketting without fancy torsion features and shouldn't result in mystery torques. You should have a template or die but if you have a fully featured fab shop there's no reason not to have the option to make gaskets out of sheet stock when the shipment of bulk gaskets gets held up because reasons. Things that went wrong a) no template b) fab shop isn't "fully featured" c) no experience modding gaskets d) guesstimating torque e) basically everything, really

Adding to the asbestos chat. I met a guy who was left for dead at the top of Everest but survived only to die a few years later from mesothelioma. When it was diagnosed he reckoned he hadn't had all that much contact with it in the first place. https://en.wikipedia.org/wiki/Lincoln_Hall_(climber) This is the guy and I just found out he grew up in Canberra a place where they've had to knock down houses because they had loose fill asbestos insulation.

Helios Grime posted:Also the clearances we use to make poo poo safe are loving genereous and it still blows my mind that videos like this can happen. So how are any of the people in this video still alive? I've always heard that if you get too close to the overhead lines you're dead, where "too close" is something like 50-70cm (2 feet), not literally grasping it with both hands. For the same reason you're not allowed to fly metallic helium balloons near the tracks. I once read an article about some drunk girl who climbed on top of a (standing) train car. Most of her skin burned off and she was in a coma for two weeks. The guy who was climbing around on trains with her took off and left her to be discovered by the railway people.

Even our "partially constructed from the leftover parts from the cold war" FDF managed to actually make training dummies which were either "bright yellow bricks with the same size, weight and shape of the granade" some of which had functioning pin-handle system, and "bright orange" with live fuse but harmless powder casing which marked the killzone and might have just enough power to blast your fingers off. Who is insane enough to make training dummies, which look even remotely enough like live weapons, so that even professional training personnel can mix them up?

If for no other reason than what possible use is the training otherwise? That's really not true as a blanket statement. It definitely doesn't extend so far as making dummy munitions visually indistinguishable from the real thing, because being able to tell them apart by looking at them is a pretty important safety tool. Training munitions in the US are frequently painted blue. If you're going to strap a dummy bomb to an airplane for a training drop, it's a pretty good thing to help you see at a glance that the bomb you're loading on the wing is, in fact, a dummy munition and not an actual bomb.

Of course you don't want dummy explosives to look like real explosives but when you're training people you train them to handle them like real explosives. Because... handling real explosives is what you're training them to do.

For the same reason you're not allowed to fly metallic helium balloons near the tracks. Different electric train systems have different voltage levels. The minimum distance of 50-70 cm sounds about right for 25 000 volts systems, which is what is used in all new electric rail lines in Russia. But according to Wikipedia, Russia has some old lines using only 3000 volts DC, which just might allow that kind of playing around, at least when the air is dry and the gloves are of the right type. https://en.wikipedia.org/wiki/List_of_current_systems_for_electric_rail_traction Apparently, tram systems tend to have much lower voltages: 750 volts DC seems to be almost standard for new trams, and some old systems are using just 600 volts DC. I also notice that there is a cut between the chin-ups and the other stunts: it is possible that the chin-ups were done when the power to the overhead wire was switched off for some reason.

telcoM posted:Different electric train systems have different voltage levels. Dielectric breakdown strength of air is about 3kV/millimeter. Even with a 25,000 volt system no way is that arcing 50-70 cm. Water vapor actually has a higher breakdown strength than air does (pure water is a lousy conductor, and H2O recombines very rapidly after disassociation which means that there are going to be fewer free ions to support an avalanche), so increasing humidity makes that 3kV/mm figure increase, not decrease.

I don't know anything about this but I imagine if it won't arc so far that's a good reason to keep that distance. Our trains here have 15-25 kV, and the recommended minimum distance is 3m (10ft) for people without electrical training and 1.5m (5ft) for people who know what they're doing. Or at least that's what Wikipedia says.
