Welp, I got to feel 11,000 volts AC across the chest tonight at work. Was surging testing some coils with another dude, and he hit the pedal while I still had the connectors in my hands. The weird thing is it didn't feel like a shock at all, just like someone thumped me real hard all the way up the arms and across my chest. Other than that it wasn't that bad. He freaked out about it and I wound up actually feeling bad for him, although it was pretty stupid. Whenever I'm testing with another person and running the machine, I let the other person tell me when to hit the juice as well as visually confirming they aren't touching it myself.

FIRST TIME posted:I was just at a store buying some groceries and they had a sign that said "6 Years Accident Free!" and I had to laugh because that's so full of poo poo and I would be scared to work somewhere that goes through the effort to hide accidents for that long. Every company has a sign that says "xx days without a (lost time) injury!". It's the lost time part that matters. Injuries happen a fair bit at where I work (mostly cuts and dropping things on fingers, there's a big push for having us wear gloves ALL the time) but it doesn't really cost the company money unless the person is injured so much that they can't make it into work. As long as you can show up and sharpen pencils/photocopy poo poo they don't count it as an injury. But lawsuits start firing off the second the worker can't make it into work. We've also had a lot of metal on metal accidents so the next person to run into a concrete bollard or a civilians car is gonna get canned I think

Arrath posted:Hydraulic oil certainly can be but that usually requires a pinhole leak from a pressurized line to aerosolize enough of it to go fuel-air, or just spray right on the exhaust manifold. And that's how a big rear end Excavator burns to the ground! You can burn sand if you try hard enough.

Red Suit posted:So one of our machines has been leaking oil and the solution the workers decided on was to put a bucket under the leak. Then when the smell of oil got to be too much to bear, the supervisor brought in a box fan to point at the bucket. Thing is, those fans have motors that can spark. Basically the supervisor rigged a loving bomb without knowing it. Buy a new hose you cheap bastards. And it's not gonna burst into flames unless like other guy said it drops on something very hot. Also buy cat litter, that what oil spill kits come with to absorb spills

I made a post about it a while back when I first started working with that surge tester and was curious how dangerous it was. A ton of people have gotten shocked by it at work, and supposedly it's not too dangerous, at least what the people at work say. The high potential testing machine we have has all this poo poo that you have to cordon off and turn a flashing light on, and only the higher ups are able to use it because it apparently is capable of killing. It's weird they'd go through that trouble just to let all the regular workers use the normal machine if it was so dangerous. Either way, I'm not going to use it with 2 people anymore, only by myself when I'm in control of it. I could be wrong, I don't know, I'm not a scientist, but like I said I'm not going to do it while trusting another person to work it while I move the clamps around.

100-200 mA is basically the fatal range. At that range it fucks with your heart and causes it to get out of rhythm. It's actually safer to take like 300mA than 200mA because at 300mA it shuts down your entire heart at once, which sounds bad but really is like hitting a reset button, so it will start in sync again once you remove the current. This is how defibrillators work, your heart gets out of rhythm and they basically hit a reset switch. Over 200mA really the problem you have is the electrical burns it will cause. Also it knocking you out and stopping you from breathing, but that's survivable with some CPR. Basically, doesn't matter how many volts you take, static electricity is like 25,000 volts or something and is fine for you. What matters is the amps and that machine probably is relatively low amperage.

You know, it might not be a bad idea to schedule an EKG with your doctor. There could be some underlying damage to your heart you don't know about, better to get on it now before it potentially becomes a problem later.

Heart problems can appear several days after an apparently harmless shock. Our yearly EHS training states that you should always have an ECG taken after a shock.

VectorSigma posted:It definitely was a backdraft, but it was the window breaking that triggered it, with fresh air being drawn in through the roof. I'm wondering if it was a backdraft, as the windows are broken and enough oxygen should be getting inside to keep it burning near them. It could possibly be fumes that were building up on the second floor finally getting a spark and igniting.

That was in my city, apparently that happened 3 separate times, took over 12 hours to put it out and ended up burning about half a block... Edit: yes they where back drafts from the floor/roof collapsing.

Yeah, as far as i know the danger with stuff that isn't ultra hot isn't having it touch your skin, but getting it inside your body where it can affect the soft tissues, and get lodged in and do longterm damage.

The hazard from uranium is primarily that it's a toxic heavy metal, its chemical toxicity far outweighs its radiological activity as a matter of concern. Even if it were pulverized and inhaled/ingested, it's a pretty innocuous decay chain and while you definitely don't want to inhale/ingest alpha emitters, you'd be far more concerned with its chemical activity on your kidneys.

Kilo147 posted:Uranium sheds when exposed to air, I thought. Alpha particles are the one I don't want in my system. You may be thinking of its pyrophoricity, but a lot of metals are pyrophoric and they don't burn when they're big solid blocks sitting in the air. Lead is pyrophoric, but you can hold a block of it in your hand without ending up with a lungful of toxic crud. Or maybe you're thinking of its oxide coating; the metal will form an oxide when exposed to air, but it's a non-protective layer like iron oxide that will flake off, not a protective layer like aluminum oxide that won't. But again, that doesn't mean it's going to shoot bits of itself off into your lungs, it's just a metal. Handle it like you'd handle lead, pretty much. Raygereio posted:In case people don't know: The isotopes of uranium that are found in nature all decay by releasing alpha radiation. Which can be stopped by a few centimeters or air, a piece of paper, or your skin. It's not just the parent isotopes you have to worry about, though, it's the whole equilibrium decay chain. In a lump of natural uranium you're inevitably going to have some bismuth, some polonium, some lead, and some other things that decay by beta emission, but they're present in such small amounts that, again, the chemical toxicity of the parent is far more of a concern.
