Tunicate posted:The MiG 25 would kill rabbits along the runway when it fired up its radar.' That one, unfortunately, is just an urban legend. They couldn't use the radar on the runway because back-scattered microwaves from the surface would gently caress up some of the other electronics, and also played hell with the radars and radios on the control tower - that's true of most big aircraft radars. To have enough power to be a literal death ray for anything in its cone at that range it'd basically have to be able to put more than 100% of it's engines total power into the electrical system, not just the 5% or whatever the generators on the engines used. (For comparison the big gently caress-off microwave transmitters on the BT Tower in the middle of London, which were more powerful and also focused beams, took a day or so to kill the pigeons that tried to roost in them - until they worked out a way of keeping them away, it was pretty common after a rainy day for partially-cooked pigeons to drop on the heads of the local inhabitants, but as they were mostly UoL students nobody gave a poo poo) Speaking of microwaves, the first application of microwaves for heating instead of in radar was for curing the glue in the laminate wings used on the Mosquito bomber - because nobody had really thought that much about it they had a massive magnetron at the end of the line pointed in the general direction of the wings in their jigs, making assembly workers further down the line wonder how they were getting sunburn indoors...

I can't find the mostly fictional account of soviet OTH radar repair teams having to keep the engine running in their truck in case the alarm rang that the radar is about light up so that they could escape. On at least one occasion the commander was unable to ring the alarm before charging up the radar, thus frying the repair team. I'm fairly certain it was mostly fiction, but a good read.

I'm guessing being in contact with something like The Russian Woodpecker when it was powered on wouldn't be particularly good for your health, but as long as you weren't made of metal just being near it probably wouldn't be a problem.

Fun with liquid nitrogen. My first job was a science technician in a high school. We used to have fun freezing stuff in liquid nitrogen and smashing in with a hammer, also hammering in nails with a banana. I kind of wonder whether health and safety regulations would still let me do that.

Craptacular posted:gently caress loops, I want someone to run an F1 car upside down on the ceiling of a tunnel. They have enough downforce, right? The problem is getting there, you'd need a completely smooth tunnel with a radius probably bigger than that loop, otherwise it'd lose downforce because of the lack of ground effect.

They make these hanger type things for ladders so you can lean them up against an eavestrough without collapsing the loving troughs. If your ladder is on grass, you'd be well served to put a sheet of plywood underneath. Tie off your ladder to the wall/roof if you can, leave a few rungs extended past the roof's edge so you have something to hang on to when you get back on to climb down. You should be wearing a harness at all times while on a roof, that part is pretty much law. I'm guessing this would involve sinking an eyebolt or two into the joists so that you have something to clip your harness into. The lovely part is having to tar over the holes you've left to put the eyebolts into, and that's probably why nobody bothers with harnesses unless they're working for a big contractor. Can you imagine the massive costs employers would have to deal with when you add an extra $15-$20 to each job?!

The construction company I work for takes OSHA pretty loving seriously, I can tell you that they do indeed include those costs in the job (Because our government medical provider will make them bleed Rutherfords if someone falls and twists something). The fact that the Directors were used to working under the safety of a good union while they were construction workers kinda helps, though.

You need to make sure that your ladder extends three feet (essentially three rungs) above the surface you're stepping on to, and it should be tied off to keep it from moving. Make sure you know the proper angle to put up the ladder too. OSHA requires fall protection once you're 10 feet above the ground, although this may be different if you're classified as a roofer. I don't remember exactly, but OSHA allows for different fall protection rules for steel works and roofers I believe. You will need to be tied off if you're on the roof, since I guarantee you'll be over 10'. This doesn't apply if there is a guard rail, or a parapet wall that is at least 42" high. Good luck getting your employer to do this stuff though, I know most local roofing companies pretty much never abide by this stuff.

On the topic of ladders, what do you guys think about going down them Navy style (facing away from the ladder)? I learned it from my dad and everyone looks at me funny when I do it.

I learned it from my dad and everyone looks at me funny when I do it. That if I saw anyone doing it on a site where I was safety officer, they'd be looking for a new job sharpish? Going down ladders facing outwards has been understood to lead to an inordinate number of accidents since at least the 1940's when the railways got serious about stamping out the practice.

It works on ships because the ladder is more like a steep staircase. If your ladder had handrails, going down facing out would be just fine, but it doesn't.

zedprime posted:I am fairly sure OSHA says to use those facing the stairs. Like anything not at a specific angle isn't truly stairs and is treated it like a ladder, so using them facing the rungs. Yep, that's the way I've been taught. Whether people actually do is another matter entirely

The proper way to use those going down is to put your hands on the rails and slide. Subs had more vertical ladder wells and all you have to do is grip the rail harder and hope no one greased the drat thing up.

Guess who just nearly got his head crushed like an eggshell! I was setting up for crane operator exams this morning with an elderly man who's not our usual practical examiner. We had a big blue barrel full of water that's supposed to be used for the exam sitting on the back of a boom truck, and the examiner decided that instead of using the boom truck's own crane to pick it up and put it in place, he'd just use the big rental crane. While standing next to the barrel waiting for him to lower the hook toward me so I could hook up the barrel for him, he promptly sent the 250 pound steel hook and ball zooming at my head too fast for me to even try to stop it. I ended up just ducking while the hook slammed into the boom behind my head. Yeah, dude's getting written up for it soon.

chitoryu12 posted:Guess who just nearly got his head crushed like an eggshell! I was a field mechanic with Unite... a large national construction equipment rental company. I had a field call where the customer complained the hydraulic fluid was low on a backhoe trailer. It wasn't low, it was empty. I filled it with hydraulic fluid and operated the levers to find the leak, and when I pressed the outrigger down control, the outrigger swung up (way too fast) and smacked me in the side of the head. Luckily, I was knocked away from the swing of the outrigger before it slammed against the side of the backhoe like an alligator's jaw. Turns out the customer swapped around some of the hoses to fit their layout preference. They wanted down to be up, etc, and hydraulic fluid leaked out of the loose fittings.

I mean, naturally you'll feel skiddish if it's too steep of an angle, but those are the guidelines we operate by locally in our industrial plants.

My dad's extension ladder has a 90 degree L sticker on the side tilted at the correct angle. When you use the ladder, you lean it so the short leg is horizontal and the long leg is vertical. Done!
