Absolutely correct. If you're clever you can use the natural convection effect for cooling so you don't need to pump oil, a lot of power transformers do that. (There are different types, ONAN, oil natural air natural, ONAF, oil natural air forced using fans, or OFAF oil forced air forced, with a pump for the oil and radiator fans.)

The scariest thing I ever saw was some moron dropping a hairdryer into an aquarium filled with oil to demonstrate the heat absorption. The hairdryer was just fine until he pulled it up out of the oil while it was still running and almost set the drat thing on fire!

This is the kind of thing that is the opposite of funny to do

quote:

Just after the flight had become airborne, Kinzer said that he received "frantic calls" from flight attendants that passengers were smelling smoke in the rear of the aircraft. Kinzer made the decision to declare an emergency and return to the airport.

After a routine landing, the jet stopped at the end of a runway and emergency response crews took a look at the plane and its engines.

An emergency responder confirmed that smoke was coming from the plane's right engine. After consulting with his first officer, Kinzer made the decision to evacuate the plane.

After a conversation between the air-traffic-control tower at the airport, the emergency responders and the flight deck, an unidentified voice entered the discussion, according to a recording of radio transmissions. The man didn't identify himself in his transmissions and urged the pilot to "hold off on that evacuation, please."

After two inquiries from the flight deck on who was requesting the delay and why went unanswered, the evacuation was ordered.

Kinzer and the other crew members were interviewed at Allegiant's Las Vegas headquarters and the pilot said he believed he made the right decision to evacuate the plane.

But after several weeks of silence, Kinzer said he received a call from the human resources department of the airline telling him that he was fired and that he would receive a termination notice by mail.

That's great.

Work's been on a real safety binge lately. Okay, makes sense, reducing workplace accidents and employee downtime directly impacts the bottom line, continuous process improvement rah rah all that TQM stuff.

To announce one of the various safety initiatives, they called an all-hands, and gave everyone a little roadside emergency kit containing reflectors, a set of jumper cables, etc.

A few weeks later, company-wide email: "You know those jumper cables? Yeah, don't use those, they're cheap Chinese junk and are way too thin and will overheat and melt if you actually try to use them to jump-start a car. Get rid of them, and in compensation for trying to burn your car up here's a $20 gift card."

Wait a year. Another safety initiative, another big meeting, another freebie: This time a USB charger that can plug into either the 12VDC power point in your car, to into a 120VAC wall socket.

If you plug it into the wall socket, guess what you see if you put a voltmeter across the metal connections on the cigarette lighter adapter part of it?

Another email: "Don't use those things, here's another gift card."

Stop. Buying. Chinese. Crap.

not caught up on the thread but I have

today i worked in the engine room of a ship. there were three fires in the space of about eight minutes. welders working on top of us in a recently painted room that hadn't been cleared of oily rags.

first fire: I didn't see, but I saw smoke and was like "wtf is there a fire? impossible, lol!" and yep someone was stomping it out. crisis averted.

second fire: spot welder threw some sparks onto a hoodie, goes up. I grab it, open a door, off the ship into the water. massive VWOOSH flames, not little tiny sparks.

open up the door for ventilation so we don't asphyxiate. I get one of the painters fans pushing fresh air into the (cramped and poorly ventilated) hold.

third fire: sparks into a PLASTIC BUCKET OF PAINT. it's on fire. the welder drops his poo poo, grabs the bucket, runs it outside, throws it into the water. chemical spill!!!!1

at this point im like hmm maybe someone should clean up all these oily rags? so i do that but also get a fire extinguisher and tell everyone ITS OKAY TO USE A FIRE EXTINGUISHER YOU DON'T HAVE TO STOMP OUT FIRES!

there's like eight people (our entire department!) working in the room, plus welders. everyone has seen it. the Boss knows. nobody tells the safety officer. i am warned multiple times if I report it, everyone will be written up (and probably docked pay). I'm pretty sure this is illegal.

This all happened saturday morning, so I have until Monday to decide what the hell I'm going to do. as a reward for surviving my first encounter with fire in a goddamn enclosed space, i bought myself some new tool pouches. it didn't feel like enough.

EPILOGUE: the guy whose hoodie that was was extremely bitchy about it. at first i was sympathetic but he wouldn't shut up and now i hate him.

also i'm really pissed that I'm the only one who thinks this was life threatening & a Big Deal

I know my internet word doesn't stand for anything but the iPod overheating on me really did happen. I just checked with a former coworker and he said the FW would make the USB iPods charge faster and "sometimes put them back to life if the battery was totally dead" so there definitely was more power from the FW. Maybe it was a defective cable/iPod in my situation, but it's still pretty stupid imo to have those 2 different types of cables be the same 30 pin.

"All that time you had a lethal voltage on those terminals. Sometimes it works, sometimes it does not."

I've used these little detectors before.
https://www.youtube.com/watch?v=MWH6xqq-qY0
The important thing to remember in an industrial environment is that those little no-contact detectors do NOT work on DC voltage. So if you are working on a 500VDC battery bank for a large UPS or a 125VDC system for switchgear, you cannot use a detector like that, you must always check using a voltmeter.

I think those little flukes work up to 1000Vac. At 2400V/4160V they start to beep at about three to four inches away.

This guy either does not know what he has there, or he was purposely misleading. Not once did he use the words "phase tester", which is what these things are (and all that they're usable for): distinguishing the live and neutral wires. You'll notice that when he demonstrates the devices "not working", he never moves them to the second terminal to confirm that they also show nothing there.


Got this from my grandfather 30+ years ago. I have no idea when it was made, it's certainly older than 50 years.
