Well, yeah. I guess the only option is to just let it keep eroding until the rainy season is over and they can shut it off, but still. Perhaps a small preview of what is to come with all the other infrastructure we have that is past its designed lifespan?

I recently bought a 200-year-old house. When we were doing the home inspection, something like one of these fire suppression grenades was hanging in the cellar. The home inspector said, "This thing needs to come out, stat."

Those fire grenades generally used carbon tetrachloride (though some used salt water), which is potentially bad news if you like being healthy. Apparently, heat can turn it into phosgene, so, ya know, toss it in a fire. The ones you can find for sale as antiques are usually drilled and the contents dumped, although that seems problematic in its own way. Years back, I bought some full ones for my firefighter uncle because they are an interesting piece of equipment. I think he stuck them in the firehouse for all to see. Hopefully they never get knocked over!

Raskolnikov38 posted:from the article the emergency spillway isn't actually a proper spillway so its better to keep using the damaged one until it stops raining and they can begin repairs There’s no control over the emergency spillway. It’s just where the water goes if the reservoir is completely full so it doesn’t overtop the dam. If water overtops an earthen dam, the whole thing fails in short order, so it behooves people to design an extremely robust emergency spillway, but you still don’t want to get to the point where water starts using it.

Volcott posted:Did you take pix? Unfortunately, no; it was there for the inspection, but was gone once we took possession. It looked like one of those grenades, but made of red and white glass, suspended from a piece of twine inside a minimal brass wire cage. I guess if there was a fire, it would burn through the twine, dropping the the grenade. The cage was probably to keep it from being accidentally knocked down. It was hanging about 5 1/2 feet off the floor, so I'm having a hard time thinking that tiny little grenade could have done much against a fire with flames that high.

Extinguishing fires with halogenated carbons is the closest thing to a magic trick, you need astonishingly little because they tend to be outright fire inhibitors in most fire circumstances as opposed to oxygen displacers like CO2 or temperature control like water deluge. Creating phosgene (or the fluorine analog for fluorinated carbons) isn't the biggest deal in the world. Homegoods are absolutely filled with chlorinated and fluorinated plastics which will do the same when on fire. Smoke inhalation is a huge killer and firefighter bunker gear is equivalent to pretty hefty chemical protection. Carbon tet is pretty mean on a health basis outright though and was phased out for a variety of other halogenated carbons with inhibition properties. Except oh hey the same sort of inhibition reactions also eat the ozone layer so the Montreal Protocol killed the common ones and it seems they're just catching back up with a solely fluorinated option.

chitoryu12 posted:I mean, what do you do? Apart from the aforementioned "helicopter dumping buckets of concrete into the hole". Concrete doesn't just cave in like that unless the underlying formation is removed. There's definitely some undermining going on, and I think just dumping buckets of concrete into it wouldn't be a really good option because it would just wash away. Now, the big question is, is the undermining due to a fault in the spillway, or is this water actually coming through the dam? Either way, if I lived downstream on the flood plain, I'd be just a tad loving nervous.

People typically think of a death by smoke inhalation as being overwhelmed by smoke and suffocating specifically due to a lack of oxygen, but a lot of the time you're straight up poisoned by fumes from burning carpet, glues, paints, PVC pipes... household cleaners.... the list goes on and on. Burning buildings produce horrible, horrible smoke and fumes. Tumble fucked around with this message at 23:42 on Feb 9, 2017 |

Fasdar posted:What is the chemical that (I assume) displaces oxygen in these? I'm not 100% sure on this, but I think it works similar to fluorated Halon extinguishers. Which means it is not displacing oxygen, but it is interrupting the oxidation reaction by raising the the required activation energy. Ideally the chain reaction - spreading fire - is stopped by that.

Some OSHA news from my general area. Yesterday at around 2:30 PM EST a pile of garbage shifted or fell over on/under some trucks in a landfill. 5 or 6 people were in trucks, all but one is currently out. Last I knew there was one guy still in a front end loader buried under 100-150 feet of garbage. This is pretty morbid but any idea how long someone could survive something like that?

Depends how old the trash is and how much organic matter is in it, even with a big air pocket I would expect swamp gas to push all the oxygen out fairly quickly

Assuming it's an enclosed cab and they weren't crushed to death instantly? The big killer is suffocation. Depending on how large the cab was and how compacted the garbage around the cab ventilation is, they could potentially hold out for several hours, maybe a day. Panicking or not turning off the engine would reduce that by quite a bit. I'd imagine that if they can't be retrieved quickly, the priority would be getting a hose to pump air through down to them, after which they can probably survive for a couple of (rather unpleasant) days while getting slowly dug out.
