For example, I was putting in new curtains in my living room this week, and I thought of this thread while I was standing with one foot on my home theater subwoofer, one foot on the windowsill, drilling the curtain rod hanger into the wall above my head.

Really? In the OSHA thread of all places you're gonna argue for letting people work right next to giant open rollers where they routinely have to put their hands 8 inches away from two sandwiched rollers? Nope, only way we're gonna get that artisinal flour taste is through bad safety practices 100 years without incident, whatever. They're putting their hand next to open spinning rollers, worse is they got employees having to work around it and the only safety plan they have is "ya gotta get er dun, be respectful of the machine". Now they're whining that they got shut down because they thought they had "some sort of exemption". I'm gonna go buy up old machinery too and start it as a factory on the cheap and then complain when I get shut down with a petition. Give me a break. He also complained that the safety inspectors showed up announced. Well yeah, no poo poo, thats what a surprise inspection is for.

I'm not saying it makes sense (it loving doesn't), just that i understand the dude being distraught when it's never been an issue. It's a classic trope that systemic issues don't get fixed until SITF.

"Well we've never needed handrails around the top of the silo, the guys just know to be careful when they're up there in all weather with no tie-on points." Yep, checks out. If no accidents have happened yet, there's no point in putting in safety features

I work on drilling rigs in Alberta and we had an awesome one the other day. Drilling fluid (in this case Distillate 822, mineral spirits based oil base mud) comes up the hole, down a flow line to a shaker box, over the shakers which separate drilled cuttings out of the mud, mud carries on through the circulating system. Sometimes, we get gas and that's no big deal. In the shaker box there is a little seperator driven off of a 110V motor, and that is hooked up to a gas head and it detects gas. When we get an unacceptably unsafe amount of gas, we shut in the well with the Blow Out Preventers and circulate the mud through a manifold and a large degasser uh, degasses the mud. The gas then gets sent out to a flare tank 50m away from the well and the gas is then burnt off, the mud is returned to the tanks to once again carry on through the circulating system. Safe as houses. So, our drilling fluid has the consistency of used motor oil and is pretty nasty. Called invert, we go through a fair amount of measures to keep in in the mud tanks and in the hole, and not anywhere else. So we had an old shaker screen cut out to go over the shaker box and around the little gas detector motor to keep splashes down. It's a wire mesh screen. It worked very well. We were running in the hole with pipe when we stopped to fill. After filling the pipe, we circulated a little while and noticed that the gas was coming up, as noted by the gas detector so we continued to circulate to see if we had to shut in the well or just let it circulate out over the shakers and carry on running in after the gas had dissipated. It was around 4000 parts of gas, which isn't cause for concern but should be watched. The 2 roughnecks (floorhands) and I were on the floor when roughneck 1 notices that the wire mesh screen cover for the gas detector was off, so he went on down to put it on. I turn around to check the gas units and roughneck 2 starts yelling fire. And yes, there was fire. Somehow gas had ignited at the shaker boxes and flames were roughly 20' high. The driller shut in the well immediately and the fire was put out. I should probably point out that the mud tanks are holding 40m3 of invert which will start on fire if given enough heat. Where I am standing. With a 30lb fire extinguisher. I'm not going to lie, I did not want to be there. On inspection, the 110v cord that powers the little gas detector separator in the shaker box had frayed from use exposing bare wires. As the roughneck had put the cover on it arced out with the bare wires causing the whole ball o' flame in his face. He's fine but he didn't need to shave for a few days. As the white hard hats from the office came out, we were praised for not getting hurt and not burning the rig down. The oil company itself claimed responsibility for the fire, saying we were running their equipment and they hadn't made sure it was in good shape. They have now tasked the makers of the gas detector to upgrade the machine which they had better since this is a very large oil company and has no problem getting rid of these gas detectors if they feel they are unsafe. These particular gas detectors haven't changed in decades either. We've suggested a conduit on the power cord and a proper lifting handle. So we went from a very OH&S, almost worst thing possible happening to the rig situation, to pats on the back, handshakes from big wigs from Calgary and possibly changing how gas detectors are built. TL;DR, massive ball of fire at a drilling rig is pretty bad, but we dealt with it and it was ok after.

blarzgh posted:I agree with Evil Bunny. From the owner's perspective, in his mind how can it really that dangerous if its never happened? "A shipowner was about to send to sea an emigrant ship. He knew that she was old, and not overwell built at the first; that she had seen many seas and climes, and often had needed repairs. Doubts had been suggested to him that possibly she was not seaworthy. These doubts preyed upon his mind, and made him unhappy; he thought that perhaps he ought to have her thoroughly overhauled and refitted, even though this should put him to great expense. Before the ship sailed, however, he succeeded in overcoming these melancholy reflections. He said to himself that she had gone safely through so many voyages and weathered so many storms, that it was idle to suppose that she would not come safely home from this trip also. He would put his trust in Providence, which could hardly fail to protect all these unhappy families that were leaving their fatherland to seek for better times elsewhere. He would dismiss from his mind all ungenerous suspicions about the honesty of builders and contractors. In such ways he acquired a sincere and comfortable conviction that his vessel was thoroughly safe and seaworthy; he watched her departure with a light heart, and benevolent wishes for the success of the exiles in their strange new home that was to be; and he got his insurance money when she went down in mid ocean and told no tales. What shall we say of him? Surely this, that he was verily guilty of the death of those men. It is admitted that he did sincerely believe in the soundness of his ship; but the sincerity of his conviction can in nowise help him, because he had no right to believe on such evidence as was before him. He had acquired his belief not by honestly earning it in patient investigation, but by stifling his doubts . . ." -William K. Clifford, The Ethics of Belief (1874)

Don't bother with rear end covering, just figure out what went wrong and how to fix it so it doesn't happen again.

Robiben posted:Not OSHA related, but whats the deal with the slow mo in this gif? It looks like it was artificially created somehow? Its really noticeable in the bottom right of the gif, its looks like a computer is blending the frames together. Anyone know what this is called? These artifacts are from a frame interpolation tool like Twixtor or something similar. It's used to interpolate images from normal speed footage to create smooth slow motion, but it will have weird blurry trails like that if the backgrounds are complex or the masking is wrong. This is probably already high speed footage from a GoPro that's been interpolated to make it run even slower.

Two guys play with a fan: https://www.youtube.com/watch?v=xfR2yE-psMk&t=90s It’s not the most dangerous thing ever, but I’m amused by the way they generated 400 Hz AC for it. wall power→drill press→R/C plane motor→17 V @ 400 Hz→Variac→200 V @ 400 Hz→fan

You'd only lose your hand it you held it exactly at the focal point, ignoring the rapidly increasing pain, ignoring the accelerating, horribly appealing stench of burnt human flesh as the device slowly chews its way into you. It's slow and agonising but you're holding your hand in the beam nonetheless. Why are you doing that? Why are you doing that, Jet Jaguar? Why?
