I work for a mining company and we recently had someone build a cabinet right in front of a pre-existing fire extinguisher, so poo poo like that doesn't shock me at all.

I get emailed a list of safety incidents every day and there are at least 4-5 every week that you just shake your head at

They started putting them in here a few years ago; before at, we had either no dedicated signal at all (usually for small intersections) or a five-light system:

-R-
YY
GG

With the left pair being arrows and the right pair being solid circles. Solid green but no arrow meant yield.

The flashing arrow makes a lot more sense to me, though I had no trouble knowing what was meant before.

Haha we have a fire extinguisher and hose reel in a recess in a warehouse. Someone decided that atwo filing cabinets full of tools and random junk would fit just perfectly in that recess thus preventing access.

Yearly those cabinets disapear a day or two before the inspectors come around.

We once had someone call the police and fire department on us repeatedly because our fire hose cabinets weren't painted red.

However, there's no law in Australia which says they have to be, as long as they're clearly marked.

Drill Pipe (DP)

Heavy Weight Drill Pipe (HWDP)

Just like regular drill pipe, but heavier and with an up set in the middle. Also, the tool joints (top and bottom parts) are longer. Fun fact, DP and HWDP tool joints are friction welded on.

Drill Collar (DC)

Mostly all steel, the have some cut out for certain things, or they may be spiral cut.

The drill string is all the pipe of whatever kind from the bit to surface

Historically, the biggest heaviest stuff go on the bottom, just above the bit. Those are the collars. Then we have the next set, usually the HWDP, and then the regular DP.

This was done for several reasons. The heavy collars take a lot of shock out of drilling, but more importantly it kept the hole straight, using the packed hole theory. Say you are drilling a hole with a 311mm bit. If you went straight to 114mm dp, there would be an awful lot of room for the pipe to flex, leading to unwanted deviation, meaning the hole is no longer going straight down. If we use 203mm collars on top of the bit they are much less flexible, and also can't go anywhere since they end up contacting the side of the hole if they do flex. We would then run 165mm drill collars on top of those for more weight and stiffness, then the hwdp and finally the regular dp.

With directional tools being used more and more, we can often forgo using the packed hole theory to keep the hole straight. If the hole does wander, it can be easily fixed with the directional tools.

As well, pipe has all sorts of different thread patterns some of which are interchangeable while others aren't. When we need to go from one thread pattern to the next, we use what's called a crossover sub, or xo.

Everything in the drill string from the bit to the regular drill pipe is called the bottom hole assembly, or BHA.

A dogleg is the change of angle of the hole. They are unwanted when we always did vertical holes. These are needed to do horizontal wells. In the build section where we go from vertical to horizontal they are reported as the dogleg severity (dls) over 30m. Say, 12 degrees over 30m.

https://www.youtube.com/watch?v=rdggdExpzeY

The left side represents a much exaggerated dogleg, the right side shows a keyseat which would be made as the pipe wears away that side.

For the most part, drilling rigs are grouped by how many joints of 9.5m pipe they can pull out of the hole and stand up to be put in the derrick. Regardless of how many they pull, once racked they are called stands.
Singles will rack one, but there are super singles that can rack 1 14m joint of pipe. Some, like the slant rigs don't rack any, but lay every one down. There are also really small truck mounted ones
Doubles will rack 2 joints of 9.5m pipe, and triples will rack 3. However, there are some triples called super doubles, which use only 14m joints of pipe, and rack 2 of those.
I believe there are quads in the middle east.
There are/were also coil tubing rigs, but we don't talk about those.

This is a triple with no pipe in the derrick.

This is a triple with pipe racked. As you can see there are 3 pipe all screwed together to make a stand.

Generally speaking, the bigger the rig, the deeper the hole. Small singles often drilled shallow holes, under 1000m. Triples usually did the longest or deepest holes., with doubles falling in between. That's really changing today, as all rigs are being built to go deeper or further. They are built to be able to pull more weight, pump with more pressure and so on, but still triples do the biggest deepest work. My employers biggest rig is rated for 8500m.

https://www.youtube.com/watch?v=y_paK1Qymp8
This is a little conventional single making a connection. Very small, very fast, not too common in Canada anymore. There are a lot of bad things done in that video, mostly with where the guys putting his hands, feet or whole body.

Check out the pipe they used for Project Azorian to like a portion of the K-129 off the sea floor, pretty damned cool.

I guess people became too dumb to follow the "yield" part. Are these yellow arrow things common elsewhere?

Edit: the first time I saw one of these, I was fighting 30 years of driving experience which programmed me that "yellow means I can still go" and having an actual arrow means it's a protected turn and I DON"T need to yield.

Yeah, this was something approved by the MUTCD awhile ago but is being adopted by most states only recently. A lot of people are confused by it but it can help move traffic in certain situations.

I still don't understand the Austrian rules on traffic lights.

Lights go in the order green -> flashing green (couple seconds) -> yellow (couple seconds) -> red
Green means go.
Flashing greens mean "stop if at all able, go if unable to stop" (so the same as the meaning of yellow in all sane countries)
Yellow means stop (it is illegal to cross at this time)
Red means stop (it is equally illegal to cross at this time).

Wow, that flashing green is weird. In some countries (Canada, for one...maybe just Quebec? It's the only part of Canada I've driven in) a flashing green is a "protected green" and is the same as a green left turn arrow in the states, i.e. no one will be coming from the other direction, so just go on through, you have right of way.

Baronjutter: Dec 31, 2007; "Tiny Trains"

I'm trying to remember some of her most or even vaguely osha-related stories:

-Rich oil dude has plane tickets to go somewhere important but his home town of Edmonton is snowed in so his plane is canceled. It's super important for him to get where ever it is he's going so he goes online and buys tickets out of Calgary which is still flying. The problem is, this flight leaves in about 2 hours. In good weather it's about a 3h drive, and that's not counting the time needed to deal with the airport. Dude has some sort of super-car like a Lambo or something and decided he can make it. He speeds insanely in the snow in a lambo without winter tires and manages to go off the highway twice damaging his car but somehow avoiding police. He actually makes his flight, more or less abandoning his filthy damaged car at the airport parking lot and calls in a claim as he's running to the gate. They managed to work out getting it towed from the airport and repaired so it would be ready for him when he came back from his important business trip. He also admitted it was the dumbest thing he's ever done, damage to the car is entirely his fault, was criminally speeding and would not contest anything, just wants to make sure his car isn't cluttering up the airport and gets fixed. Was apparently a very nice guy.

-Oh man I forgot about one of my favourites, which is also fairly OSHA for the lack of upkeep at this parking lot. So a guy is parking at a big popular strip mall parking lot and just barely grazes a lamp post. The huge lamp then falls over landing on quite a few cars and narrowly missing people, no one was hurt. A police officer who happens to be at the scene noted that the lamp post seemed to be rusted through and the guy barely touched it. While this is happening an old guy backing out of a parking spot sees this, gets spooked and hits the gas instead of breaks as olds tend to do and slams into, you guessed it, another (smaller) lamp post at full speed, knocking it over too. The old guy who hit the lamp is now having a panic attack and gripping his chest and collapses and had to be taken away an in ambulance. But the best part is that some random old lady who watched all this play out from a very safe distance then decided to pretend this was all traumatizing and carefully "collapsed" while screaming and crying, then demaned insurance money saying she was traumatized by witnessing the events and now has PTSD and can't sleep. Engineers confirmed the first lamp was extremely unsafe (it had lost about 80% of its structure to rust) and the shopping centre had to pay through their insurance for all the damage to cars in the parking lot, old guy was fine and didn't have a heart attack but the damage he caused was totally his fault and on his insurance. Old lady was told to gently caress off, she threatened to lawyer up but they never heard from her again.

There is no arcing at his neck. If there was, he would immediately stop.

There is a welding ground clamp he's dragging around, so the steel plate guitar is grounded through his sleeve and he's shredding it with an electrode in his hand, but the resolution is too bad to see the exact setup.

Maybe the strap is the actual ground cable.

That may just be Quebec because here in Vancouver a flashing green light is an intersection that will always be green for traffic going straight through unless a pedestrian presses the button to cross. If you're turning left you'll still have to wait for cars from the opposite direction.

I've definitely been shocked by lovely grounding at sketchy DIY spots all over America. The worst part is once it happens to you once you know the signs.
No stage, check.
Carpet, check.
PA consisting of 2 speakers that look like they've been through a tornado, check.
"Sound Guy" (incredibly loose term) saying, "Yeah all of you can plug into that power strip back there."
PA also plugged into that power strip.

And finally after you ignore all this because you really just want to play this stupid warehouse, get your $200, and get the gently caress out of El Paso, you walk up to the microphone, and riiiiiight as you are about to say something, you can feel the faint tingle on your lips, and you loving know whats about to happen, but it's too late, and POW!!!! Feels like getting punched straight in the teeth.

Then you put a coozy on the mic, and finish the show, avoid the girl on opitates who "Like, reeeeeealllly likess syour banddd, you guyssz played firstt riighhh? I haveee some heroion if you wannntn!!!" and you roll on down the highway to the next place, hopefully an actual venue this time.....

uhhh actually, my buddy got the poo poo shocked out of him because of a ground loop while playing electric guitar. He was barefoot on the football field at homecoming holding his guitar and singing into the mic. Every time he got close to the mic and touched his strings he'd get zapped. He probably would have been fine if he was wearing shoes but whatever.

I think it might have had more to do with the mic being phantom powered than the guitar, but he wasn't getting shocked unless he touched the strings so :shrug:
