Detroit public school conditions. It's pretty horrific stuff, honestly. http://m.metrotimes.com/Blogs/archives/2016/01/14/detroit-teachers-are-using-twitter-to-document-poor-school-conditions At this point, when is the entirety of Michigan just going to be one big OSHA violation?

I was very confused for a moment trying to work out how one sits in a chain. Also, unless they meant to write "roll backward" instead of "roll forward" I cannot for the life of me picture how that went down.

SumYungGui posted:Wow look at Mr. Killjoy here. Wood's non-conductive dummy, everything is safe geez. Back in the early days of local loop unbundling (other ISPs being allowed to install equipment for voice and DSL in incumbent telco BT's exchanges) BT were only obligated to provide 10A of power to their "tenants". The standard build consumed 9.6A of power, so everyone's happy, right? Nope, in some exchanges BT kept that 10A limit with a simple 10A fuse. Any time the temperature got above about 30 degrees the fuse would blow (and of course they went randomly all the time) so every single customer lost phone and broadband until some fat-arsed BT engineer could get round to replacing the fuse. We weren't legally allowed to touch the power cabinet but there was nothing stopping us plugging a big-arse box fan into the cleaner socket and pointing it at the cabinet... the end result was a court case that was basically "Nuh uh I'm not touching you you can't do anything" but with £1000-a-day laywers instead of 7-year-olds.

m2pt5 posted:From that PDF: It's not: quote:In accordance with 29 CFR 1910.399, Readily accessible is defined as "capable of being reached quickly for operation, renewal, or inspections, without requiring those to whom ready access is requisite to climb over or remove obstacles or to resort to portable ladders, chairs, etc." This definition, however, does not preclude the use of a lock on the disconnecting means (circuit breakers panel), provided those, for whom ready access may be necessary, have a key (or lock combination) available. Additionally, the National Electrical Code (NEC) 2005, Article 110.26, partly states, "Enclosures housing electrical apparatus that are controlled by a lock(s) shall be considered accessible to qualified persons." "Blocked or inaccessible" means "there's a bunch of poo poo piled up in front of it," or "someone drywalled over it," or "there's an old Master lock on it and nobody knows where the key is." It doesn't mean "the people who are qualified to enter the panel have it locked and they have the key on them at all times."

BANME.sh posted:again, how do these obviously untrained people get ahold of such expensive machinery and are they horribly in debt when they inevitably lose it in a mudslide or in a body of water? Oh, how I love working in a crane training/certification business. Many less scrupulous labor companies (not just construction, but also stuff like heavy duty groundskeeping for massive swathes of public lawn or tree trimmers) recruit people with little to no training and put them to work immediately or almost immediately, sometimes putting men to work the day they arrive looking for a job. Immigrants and youths are also much easier to pay less than minimum wage, especially if you're running a business that just pays them cash under the table without bothering to leave a paperwork trail. This is what gets you Mexican immigrants who can't speak English working for a business with only one informal translator being thrown onto a compact roller without training and told to just "Do what that guy is doing", until they drive up a steep incline and flip over. It's worse in third-world countries or some first-world countries with massive poor populations and poor workers' rights (like China) where everyone can be paid less than they really should get for their work if it's simple labor jobs. I'd imagine that unless the machines are communally owned by a group of private citizens for local work, they may have a larger company taking advantage of cheap labor with untrained people looking for work in a country with poor regulation.

You can also stack them to increase load capability. You can knock enough poo poo off shelves or hit people with a normal forklift. Those give you the advantage of turning on a dime without backing into things. You could even turn with the payload in the center of the turn. I do want to see a new Gabelstablerfahrer Klaus featuring one, though. -e- suuma posted:Mecanum wheels have been around for like 30 years.  -e2- Updated the load cap. for the wheel.

They're surprisingly expensive and they wear out relatively quickly, because there is always some amount of sliding involved in any movement. (The basic concept is that each wheel produces a torque at 45 degrees to the axis of rotation, and by spinning them at different speeds you can combine those angles to sum to the direction you want...but it means that going straight requires you to cancel out the angled torque of one wheel with the other one)

Rahul posted:Came across this at work today: Eh, I've seen some PLC/RIO (Programmable Logic Controllers/Remote I/O) that were even worse. This is by no means a "horror story" cabinet. Are those VFDs in there? We never put VFDs and PLCs/RIO in the same cabinet. We try and keep analogs (4-20mA, thermocouple/RTD and Ethernet), 120V digital signals, and power wires as separate as possible too. So in some cabinets we'll dedicate one side and set of terminal strips to analogs and the opposite side to digitals and make sure they never cross. (Also using twisted-pair shielded for analogs as much as possible.) Three-Phase fucked around with this message at 23:31 on Jan 19, 2016 |

Yep, those are VFDs, and yep, that's a modicon PLC rack on the second row. Pretty much the entire plant is wired up like this. Incidentally, the reason I actually got called out was because a PLC in an ajacent panel had failed. I forgot to snap a pic but the power supply module had a suspicious brownish yellow stain on top, and was littered with mouse droppings. Oh, did I mention that this place is a food processing facility?

Is this one of these "We bought a panel designed and installed by this A&E firm... then we started making some small modifications*... yes we have the original prints but it's been modified so much by so many people the prints are now worthless" situations, or close to that. (Worse variants: "The A&E never gave us the prints" or "this guy who left/died/was fired knew where the prints were".) One of my favorite things at a facility is an electrician or technician telling me "There's this device in here, we have no idea where it's from or what it does, or if it even still functions, and it's not on the prints and none of the wires are labeled. Oh and there's a green wire that has 120Vac on it." * - The first things to disappear in a panel are the Panduit covers. They're usually all in a pile in the bottom of the cabinet next to some rotting paper prints, scribbled settings, strip chart printouts from testing, and whatnot.

(Worse variants: "The A&E never gave us the prints" or "this guy who left/died/was fired knew where the prints were".) I'm working on a fairly new building, went up in like the early 2000's or so that just got an addition. It had a fairly old style of fire alarm system in it because the large institution that owns this building decided in the 90's that this will be their forever standard panel/system and the vendor was forever good. Very quickly the fire alarm system landscape shifted and that company is regarded as a relic and that style of panel is regarded as hopelessly dated even by the early 2000s, but they stick with them because large institutions hate change. Anyways, the new addition is constantly activating the old fire alarm system because none of the people who wired it up know anything about this ancient grandpa tech since the other brands are standard now. They've been digging into the system for a month now and everything is an undocumented clusterfuck. The shiny expensive building is barely usable because the fire alarm keeps going off, and to make it not constantly go off they have to compromise the entire system. This is what happens when you let huge institutions make sweeping edicts about technical issues they don't even understand.

Three-Phase posted:Is this one of these "We bought a panel designed and installed by this A&E firm... then we started making some small modifications... Yeah you pretty much nailed it. The place currently is producing nearly twice the product it was originally designed for, so everything has been added onto over and over. There's been several occasions where I've spent an afternoon tracing wires/cables in order to work out how something works since the drawings are either missing or obsolete to the point of uselessness. The company doesn't really believe in preventative maintenence either. Things don't tend to get fixed until issues affect production and there's no other option, which leaves the on site electricians coming up with 'ingenious' solutions like that desk fan in order to keep the place cobbled together and running at least until the next shift.
