Platystemon posted:/r/whatisthisthing: “I found this while using my metal detector. Can anyone help? It’s not magnetic, doesn’t spark when grinding. Doesn’t drill at all and is incredibly heavy and tough.” Somehow I made it until like 3 days ago without ever hearing about the dangers of Beryllium. It's not really used in the previous industries I've been in, but I'm surprised I didn't pick it up through this thread or osmosis somewhere. After reading about it, I was chatting to my coworker about it, and he told me stories of a dude who he caught hand-filing BeCu bushings on a helicopter, to make the shear pins for the blades fit, which is pretty thread appropriate for a couple reasons.

beryllium turns out to be really good for making speaker drivers, and it's one of the few things in audiophile-land that actually justifies it's high price because of what a nightmare it is to work with

THE DUALITY OF OSHAquote:My thoughts exactly. Out of all the factories and plants I’ve worked in, the one that used beryllium copper was by FAR the most secure, had the most regulation and PPE. We had to shower before leaving and use captive clothing. Then again, if it is beryllium, OP will be able to afford his funeral and anyone else’s that was nearby. quote:As what you guys call an industrial hygienist...he will be fine...he would need years of continued exposure and the way he likely cut this would have not generated significant quantities of either inhalable or respirable fractions. The reason plants that process beryllium have such tight controls is because of the increased exposure of repeated activities and ultimately years of said exposure. Even the most significant sensitisers are highly unlikely to cause issues without significant repeated exposures. I’m of the opinion that it’s probably not BeCu, how would BeCu scrap end up in a hole on the Yorkshire moors? But it is a weird looking and acting cuprous alloy, not your typical brass or bronze, and I certainly wouldn’t go at it with power tools. e: Oh yeah here’s the thread in case you want to read six hundred mostly pointless comments.

A friend of mine is a hazardous material abatement inspector. She had one job at an aerospace shop where some idiot decided to throw a piece of BeCu onto a machine tool with no dust/chip collection considerations. After the place was inspected, they had to dump the machine tool outright (don't recall which one, some kind of saw i think) and decontaminate the rest of that room in the shop.

A project I was working on had a serious discussion whether shorts should be banned in the office, because it would be unfair if the computer touchers in design got to wear them and the construction crews would not. Our OSHA equivalent doesn't allow shorts in construction work. The office AC was way too cold for indoor shorts, but it was a delightfully petty discussion nevertheless.

In NZ/OZ so long as you're not wearing thongs (known as flip-flops to decent people) it counts as having all required PPE.

These days tho they aren't even Korean or Vietnam war vets so it seems almost stolen valor. Some old time time truckers, or riggers, or fishing boat guys up north still have worthy stories to sit through it. Or you can just tell them and catch a a bit off a riff about why youre looking at their nuts. I knew a guy who worked on the https://en.wikipedia.org/wiki/BAC_TSR-2 But he was British and wore pants.

That would probably give you at least an indication about what it is not. Could it be a massive ball of depleted uranium, from some tank armor or whatever?

Two of my coworkers wanted to make a beryllium Kolsky (or split-Hopkinson) bar. For people that aren't scientists with a background in high rate mechanics, that's a piece of scientific equipment for measuring material strength under impacts (because the rate at which you load something often alters how it behaves.) This involves at least two long metal bars, plus the projectile, which is often but not necessarily the same material as the bars. The projectile is then fired into one bar, generating a strain wave that propagates down the bar, is measured, propagates through the sample, propagates down the second bar and is measured again, and then either bounces back and forth until it dissipates or is captured by a third momentum trap bar. One dimensional wave mechanics and math happen, and you get out stress and strain in the sample over time. Steel is the most common material, but since the bar material influences the magnitude and timing of the strain waves you can measure, plenty of other materials are used for specialized applications. Beryllium is theoretically nice because you can get very high wave speeds and, related, very high strain rates. As you might have realized from this description, though, every single test involves hitting the bars very hard. Safety took one look at the concept and said absolutely the gently caress not. My coworkers argued that the bars wouldn't be damaged, and thus would not be releasing harmful dust, and would be essentially inert and harmless. Safety was not convinced. I think I heard at a conference that one of the national labs built one, though.
