BattleMaster posted:I took a class on risk analysis and I chose elevators because I used to be afraid of them (and in buildings that are tall enough to feel how long the cables are, still am) and learned that most of the people who die because of elevators die by falling into the shaft, either while it is under construction or because they are rescuing someone and gently caress up or try to escape and gently caress up. It seems like if you manage to get into the elevator car you're pretty safe as long as you only try to leave through the door. Due to some messed up poo poo when she was a kid my mom is severely claustrophobic, including not riding in elevators. In her 20s she was seeing a psychiatrist and his idea was to get two big grocery bags (paper grocery bags back then) with tall stuff like celery on top so she can't see over the bags, then just step onto the elevator without looking and concentrate on counting the celery leaves. So she does it, she has this forest of celery blocking her view, the elevator doors open, but she just can't stop herself from taking a peek: the elevator car wasn't there. For whatever reason the doors opened by mistake. That's when she decided to just live with her fear of elevators and take the stairs.

PittTheElder posted:Have the video of the guy getting sucked into a jet engine been posted here? https://www.youtube.com/watch?v=5FsrNEeqd6Q The indicator lights on 737s are the same orange-yellow hew as basically every standard always-on running light, and the indicator lights blink real slow. Even brand new EMBs use the same indicator lights and it baffles me because the warning lights require so much specific attention to actually notice. How many planes do I drive behind in a day? A loving lot, I cannot be careful enough. I've seen dudes get hit by full-on jet blast but never someone unwittingly get in front of the engines in the same circumstances. Not so nice to see the horrifying results of that.  The APU on jets is very, very loud and creates a visible heatwave just the same as a running engine. Yet I go under the wing with APUs running during nomral fueling procedures all the time. So what you might think would be the 'obvious' sign to watch out for isn't really obvious at all. Not a day goes by where a wingman doesn't wave me forward when the indicator lights of a plane are still on and I just loving sit there while they get frustrated and gesture more frantically before shrugging and turning their back. Not happening man.

Speaking of planes, KLM ground workers at Schiphol Airport wanted to go on strike because they feel they are underpaid etc etc. Strikes are a legally protected way of protest in this country, except when one causes a large disruption of society or security. So a judge said that in this case a strike at Schiphol isn't allowed until the end of the tourist season. The employees/union have now decided instead to follow the regulations to the letter. They'll keep strictly to the maximum speed for driving luggage to the planes. They won't lift heavy pieces of luggage by themselves, but make sure there's the officially required second person around. Because of this, loading a plane takes like twice as long as usual, causing quite a few delays for travellers.

BattleMaster posted:I don't get it, did they manage to completely avoid noticing the very prominent power lines? My understanding is that fatal accidents involving lifting/moving objects coming into contact with overhead power lines is a pretty common way to get killed. Common overhead voltages (at that sort of height) can range from 2400V to 14000V and you really don't want to get shocked by that. Motivations include planning your route and movements ahead of time, using non-conductive ropes as guides instead of touching equipment, and coordinating equipment moves with a spotter. One other factoid: at voltages >600V electricity can basically "blow through" the layer of dead skin cells that typically provides a fairly high (kiloohms when dry) amount of resistance. So that makes shocks at higher voltages inherently much more dangerous besides just ohms law causing an increase in current alone.

Sanctum posted:I fuel 737s and thanks for the nightmares. Jesus christ that takes getting degloved into a whole new level. If anyone unfamiliar ever finds themselves on an active ramp, the rule is nav lights (the red/green/white lights on the wing tips and tail,) mean the aircraft has power, and the APU might be running. The red rotating beacon (one on top, and one underneath the fuselage, generally. Newer aircraft have LED beacons that flash, but don't rotate,) means the aircraft has a running engine, or is about to start an engine, or is about to be moved by a tug. Beacons mean PAY ATTENTION. Strobes on the ramp means someone is doing a walk around or forgot to turn them off.  Also, good on you for ignoring wing walkers. I'll take direction from the guy at the tug, plugged in and talking to the flight deck, but the wing walkers don't know poo poo.

Hard rubber has an order of magnitude lower resistivity (resistance per thickness) than air at room temperature. It's still something like 100 gigohms for a centimeter thickness but if it can arc rubber won't help. When you get in the hundreds of kilovolts that stops mattering due to air's lower breakdown voltage. dis astranagant fucked around with this message at 15:05 on Aug 21, 2016 |

When you get in the hundreds of kilovolts that stops mattering due to air's lower breakdown voltage. When you apply enough voltage, anything will conduct. It's actually the mechanism by which RRAM works: Induce breakdown, which ionizes the insulator and causes it to act as a conductor even at low voltages.

The other problem is capacitance. So let's say you are wearing huge rubber boots with a good resistance and grab onto a high-voltage line. On an AC circuit you will get some current flow due to capacitance. Remember with AC there isn't really a directional "flow" of electrons, they just all move back and forth. So even if you had infinite resistance, AC current can still flow due to capacitance. It may be very little current, but it still flows. If you apply DC to a capacitive circuit and measure current flow, it'll be very high then rapidly drop to zero as the capacitor charges. If you apply AC to a capacitor, AC current will flow depending on the circuits impedance, voltage and frequency of the supply, and the size of the capacitor. You can use this a a filter component - a device that lets through or blocks certain frequencies.

It's not conduction when it's in a vacuum but it's electrons breaking free and travelling through space. It can happen at lower voltages if the metal is hot which was done on purpose in vacuum tube electronics and cathode ray tubes. It can also happen if the metal has a sharp point where the local electric field is strong enough to start pulling electrons off.
