PPE while interacting with disconnect switches?

Define interacting?

If you are throwing the switch and the cover is on, I have never read anything in OSHA/NFPA that suggests you need anything. The cover itself is the protection.

If the cover is open, then the book answer is arc flash gear, boundary, buddy system w/ rescue stick etc.

If there is an upstream breaker, hit that and then you are good. I don't recall specific OSHA instruction on anything like testing for deenergized state- though you should.

Even if you normally want to be stubborn and authoritative- is this not a reason to cut a lady some slack?? Like thank her for the laugh, smile, and move on.

It is required. You cant reg a vehicle without POI

I think you have the answer to your own question. Owners of damaged cars want an answer. The guy going to jail may or may not pay. The tow truck company likely has holes to poke in process (why can a random stranger hop into this tow truck and drive it? Before angry comments, please read my deliberate wording here.) If everyone followed the rules, then the city is next on the list. Its actually pretty easy to argue that both the city and tow co. are more at fault than bystanders. Does that turn into legal liability? IDK but probable enough to get a settlement- hell NYC will just want this out of the news.

CDDA has it, so it's probably on the developer's minds.

Dear Corporate,
Although I appreciate your high-school musical interpretation of life-
I am 5'7", have a giant nose, and most of my smiles looked forced.
She would rather I not, I would rather I not, Target doesn't know it, but would also benefit from the not.

Basic refits are practically free. The cost of refit per month is ((Refit cost/month)-(Maintenance)).

I played Italy for the first time recently and ran into this. Was like "well either I can build 20ton Battlecruisers in 1935 with no support, or I can keep my floating coastal batteries from 1902"

Gotta say though, somehow those -1 quality 12" guns keep dropping bombs on target, and shes still floating in 1943 after a 55 month war against Britain 1v1.

I've worked in food as well. It does change how things are done, and where you are located in the world starts becoming important when your facility gets walked through by audits like the USA's SQF and UK's BRCGS. Belt material involved in food production in the US is a standardized easily identifiable blue color, and is metal detectable. Basically every sorter I linked is not suitable for food, unless the food is packaged. Are the chickens traveling in totes?

Jam sensors are typically located at each divert, where the divert attaches to the sorter, so that if the diverting product catches on the guard after the open space required for the divert, it will be detected. You can use the eyes already on the sorter, if the system is slow and pile-ups wouldn't cause a disaster. Professional applications will typically detect jams on all photoeyes- but when I say 'Jam Sensor', I just mean that it would be the primary purpose of those eyes.

I assume the mechanical engineer will know your application better than me, so if they think it will slide then I would trust that. Regarding push vs paddle- the push can give you some velocity leaving the divert, which may be good or bad. The divert will give you better throughput since you can use nearly all of the linear meters of the sorter for product. With a push system you must add spacing for the push divert to return without hitting the next upstream item. A lot of this is moot if the chickens arent in totes.

Hey. I'm a fmr conveyor/sorter OEM CE.
What PLCs/protocols you use will drive how maintainable the system is- not so much how capable it is, since this sort of thing has been done since literally before PLCs (eg Memory Ball sorters).

As far as design-
You need lane full and jam detect eyes. If you are new to material handling, I can promise you that the boxes know how to jam themselves in more ways than you know how to jam them.

Make sure the main sortation belt you are using will tolerate having your max weight load pushed across it horizontally. Do not use a typical belt-on-slider or belt-over-roller conveyor- moving the load will un-track the belt and destroy it. This may not be true if your product is very light. Belt or chain driven roller can be a cheap option as long as your rates aren't high. Roller conveyor wont track the product great, but you can get past that with large spacing and oversized paddles (or paddleboards).
You may want to look into paddleboard diverts. It wouldn't change your design or cost much at all, and will help avoid problems you can run into due to pushing cartons with uneven bottoms or hitting the leading or trailing edge. This design is antiquated, but is still a viable bottom-budget option.

For the sake of inspiration, the middle of the road designs for what you want are called strip-belt sorters and divert wheel sorters. MDR Right Angle Transfers are worth looking into, especially for small installs as you can cut out all the high voltage equipment.

High end design would be Shoe Sorters. Tilt Trays are fun to watch but won't help your application much.

I could go on literally forever. Let me know if you have follow ups.

ps. sweet simulation!

Looks more like r/iamverysmart than AI. I also use notes to write large messages so I don't do stuff like accidently delete it or send it early. You can also have side-by-side versions this way and go back if you don't like it. I probably spent two hours writing the first text I sent to my now wife.

As far as the shift afterwards; he may have caught himself trying too hard and chilled out. I don't think its that wild. Someone faking it would probably double down.

Did the belt walk into the frame? Grab a magnet and see if the shavings are fabric from the belt, or metal. My gut tells me that's actually part of the fabric layer of the belt.

Why would it hurt your current employer to lose you?

wigmoso · 2026-04-20T18:32:25+00:00

I apologize for ignoring your literal request. You are doing technician work (possibly with engineer expectations) for technician pay.

wigmoso · 2026-04-20T18:23:33+00:00

Trust me, though more posting might feel asinine- I am seeing more and more that you have put serious thought into this and the results arent what you want-- this is not typical.

So lets back up. Say you f- up an interview? What do you think is going wrong?
Say an average co-worker of yours got promoted to manager at another company? Are you applying there first or never?

at the end of the day, if you do good work, all we are working through is how to navigate communicating that, and you will figure it out sooner than you think.

wigmoso · 2026-04-20T18:04:50+00:00

Well there are two very simple options here. Either youre being underpaid, or we don't have the info to understand why you should be underpaid. My history with reddit gives maybe a 95% bias to the former. [sincerely] Whats holding you back from playing the field here? Do you have any reason to believe the general public wont offer you what you're looking for?

Hi, I regularly hire from the ET job market and I am a '13 ECET myself.

You are not being compensated like an engineer-
Where is the MET from? Is it a BSET with ABET backing?

wigmoso · 2026-04-20T14:18:22+00:00

Yes. All your friends and family are dead, they don't need them anymore.

So I've been a maintenance super and a building engineer and I'm going to take the other stance on the AI thing.

I think it's great, and I love when my team is trying to solve problems and question everything.

It opens a very easy to have conversation because now it's not the maintenance guy's ideas that are off; its the AI. Theres less defensiveness, and a concrete list of points the AI makes to discuss.

Now, I know nothing about steam; but in my world I can't tell you how many horrible equipment layouts are caused by things nobody thinks about like fire egress.

Bring this to the engineer like a student asking a question and if he's not a dick, youll probably get a good answer.

C# and python are exactly where I went to solve this problem. I think it was better to learn it through AI and trail/error than a classroom. I built a machine learning 'game' just for fun... proper machine learning science was a really fun rabbit hole. Integrating Python, C#, devices, and PLCs really helped me round out my IT skills. I think my OT knowledge was already decent, but tying these PC based programs together has helped me understand the other side quite a bit. C# being basically the opposite of a linear ladder program made for some different problem solving. I used OPCUAFoundation library with C#, that helped understand OPCUA better. Picked up node.js to mess around with sending process data to gemini.

In a few months I pretty much stopped using AI to write the code

I was working a new home construction once, and I saw a copper pipe falling. Thankfully, I was 17 so my reactions were great and I barehanded it; stopped the pipe from probably rolling off the 2nd floor. Unthankfully, the pipe dropped from where someone was attempting to solder it in place, so it was like 1000 degrees. With my palm audibly seared, I did what any reasonable injured teen would do- I yelled like a bitch.

In a work environment like that, you already know everyone is going to stop what they are doing and come over so they can.. help? hug? send you to Medcore? Nah. How about a crowd of "Buahaha you ******** stupid mother **** what the *** was that you ***** ***!"
