I've probably posted this one here before when the topic of unshored trenches comes up, but I'm posting it again. Years ago I was drilling at a site that was contaminated. The owner of the property was attempting a DIY remediation system, by injecting some At one point, he cut out a piece of floor in his shop. Probably about 3 feet wide, maybe less and about 20ish feet long. Then he dug a trench the length and width of the cut and probably 7-8 feet deep. Dude had a step ladder down in to it, that barely reached the top of the trench, let alone sticking 3 feet above, or whatever is proper for such a thing. And absolutely zero shoring. His aim was to drill holes horizontally along the trench walls and "inject" this I'm not even sure how the trench stayed open as the majority of the soil was sand with just a little bit of silt. They had a garden hose "incase the walls collapse, the guy can run to the hose and breathe through it until we dig him out".

gloom posted:Oh my god that is horrifying, thank you. How would someone run to the hose location during a collapse, though? Feels like another layer of bullshit on top of an already unsafe situation. Clearly you should be breathing through the hose the entire time just in case

The hose should be running at all times so you can 'float' to the top in case something goes wrong.

I have no idea. It was more than a decade ago so I may have forgotten a few details. Like maybe there were two hoses?

Here's a fun diagram from that Review of Criticality Accidents publication. Also I have a new favorite one from that document: some Soviet workers at Mayak created a criticality excursion by tipping a container onto its side to dump it out instead of siphoning it as specified. The solution initially had favorable geometry of a big flat puddle at the bottom of the vessel, but when they tilted the vessel 45 degrees it sloshed into a more compact configuration and, to quote the phrase that appears again and again in that document, "the operators reported a flash of light and the radiation alarms began to sound."

Lord Stimperor posted:Ramming wasn't common, but it's something that pilots did in WW2. The Royal Airforce derailed V1 (cruise) missiles by giving them a push with their wing. Late in the war, the Germans tried to make plane rammings a thing. They were producing more planes than pilots and in order to reliably take down a bomber, they had throwaway planes that would intentionally collide with and shear off the vertical stabilizer from bomber planes. Didn't work out. In the V1 case. I don't believe they actually touched. Just getting in close and bringing the wing up under the V1's wings would disrupt the airflow enough to flip it over and make it crash.

EvenWorseOpinions posted:vvv not a pleasant image vvv Could you please change that to a URL. Someone with a piece of an aircraft through their goddamn eye was not something I really wanted to see when my cursor moved over it. Also, NMS and NWS tags will stop images from automatically being changed to inline on most SA apps.

EvenWorseOpinions posted:Happens with other aircraft too; the joke is you can tell a Cessna pilot from a Piper pilot by which one has diamond shaped scars on their forehead I did that once - sorta. Doing the walkaround on a Cessna 152 trainer, thinking about the weather report saying fast moving showers passing through. So like a dumbass, I'm checking out the sky and sort of crab walking along the trailing edge of the aileron. "What they talking about? Barely a cloud..." Smack! Not a wick fortunately, but that thing was basically like a sharp edge on a corrugated garden shed and at eyeball height. So I had crusted blood on my temple as I practiced touch-and-gos that day.

The car group I'm in on facebook is mostly people asking for advice or showing photos of their freshly-polished paintwork, but there are regularly idiots who posts photos of their dashboard saying things like "Wow, just hit 50,000 miles!" or "Anyone know what this warning light means?" while the speedo clearly shows they're travelling at 75mph.
