Cops never wear their seatbelts, or at least city cops where I am don't. 100% the belt is buckled in behind the driver so the chime doesn't go off all day long and they just drive around sitting on the belt driving like maniacs. Pretty crazy and I expect it's a big factor in how many are killed or injured in crashes.

It definitely does... the reason most do it is because if you have to get out of the vehicle quickly, the belt is going to catch on all of the poo poo on your belt. You'll get hung up and kinda stuck until you unfuck yourself.

I had the same experience in a different life, doing basically law enforcement work under a contract with a municipality. I always wore my seltbelt and I got hung up a few times because of it. Saved my rear end when I got t-boned by a drunk driver while on patrol... but both vehicles were doing 30 mph, and all I ended up with was some deep bruising on the front part of my upper thighs (aside from really bad whiplash). I feel confident in believing that if it was a higher speed accident that both of my femurs may have been broken.

You really only have two options with the belt... place it above the belt and over your abdomen, or under the belt at the tops of your thighs. directly over the belt is really uncomfortable and may slide up/down anyways for whatever reason.

My brother was in a 120+ mph chase before the transmission in his car gave out and he told me he realized he was doing that without a seatbelt about halfway through. I told him I was glad the transmission went out and he said gently caress that, the guy got away and he had to drive 10 miles on the shoulder of the highway at 8 mph with his lights and siren on to get back to the city because they had no tows available.

Adjacent to the property where I work were the last few commercial row-house holdouts in the downtown DC area that avoided either renovation or redevelopment in the 80s and 90s. These particular properties had a 'rich' history dating back to the 19th century as many things including shoe shops, bakeries, tattoo parlors, and brothels, possibly several times over, before falling vacant in recent years. A few years ago, ahead of a long-awaited project to develop the lots to a modern mid-rise multi-use building, the structures were razed and their rubble used to fill the footprint; however, the basement wasn't totally demoed and filled. Since then, the rooms that extend into the alley have continued to deteriorate.





This little pit is about 6-8 feet deep and is just waiting for a trash truck to wander a little too close and cause some excitement. Someone has helpfully already run over one of the cones another engineer stuck out there; I keep expecting to hear a noise one of these mornings.


I'm also told the old coal room that extends out under the sidewalk in front features similar conditions, but is a bit more reinforced. One hopes so.

You've gotta get a thermal camera for your PMs. It's not bulletproof but it can discover problems brewing really fast and not just for electrical systems.

I was working with electricians on an ancient (like 60-years old) 480V motor control center (like a big set of cabinets) from hell. It included several dangerous problem areas including a breaker that had a phase that was so badly overheating on the line side that almost all the insulation had disintegrated. I was so glad when we junked that POS.

I really prefer doing medium voltage work (generally 4.16kV-14kV) over low voltage anyways. Vacuum interrupters with a 1000MVA rating man.

We contract for IRs every 18 months, summer and winter alternating. The last IR was in winter so this equipment wasn't running, but I don't think it's been a problem for long or it would failed catastrophically. I'd love to have an IR imager, but the... uh, pennies are all preoccupied from above.

How does it extract smoke without bringing in fresh air containing a new supply of oxygen?

Typical sequence of operation where I am is fans pressurize the stairwells with fresh air for evacuation, supply dampers shut to prevent feeding air to the fire, return fans ramp and suck air out of the building through an exhaust damper on the roof. The HAVC won't supply air to the fire but it does make the building negative and will suck air in where it can around the envelope and the stairwell doors harder to open (which is part of why there are supposed to be floor marshals who assist evacuation). I don't think the idea is to keep the fans on the whole time the fire is fought, but just long enough to safely evacuate. There are controls in the fire command room for fire fighters to turn all the fans on or off.

Based on employer polls, a bit more than half of American companies drug test everyone they hire, but that number has been falling in part because so many people are failing their drug tests and it turns out not to matter a whole lot if your employees get high on their own time. Though there's a big problem finding candidates for police departments where otherwise qualified candidates smoked weed in the past, increasing legally too.

Years ago a girlfriend had a Christmas wreath of real pine boughs that she kept up into the second week of January or so. Apparently that was long enough for the thousands of praying mantis eggs in it to hatch. It was extremely freaky to notice the walls look like they were moving, but see upon close inspection that it was innumerable white baby praying mantises. I had to vacuum them up while she cried in the bathroom over the mass murder of cool baby bugs.

The point is that harsh penalties can have unintended consequences such that past a certain limit you aren't further reducing infractions but actually increasing them, particularly when a driving license is almost causal to employment.

I have no data on whether most US jurisdicitons' penalties are well short or close to that limit, but it takes more consideration than "drunk driving is bad so punish it maximally" and defies comparison with jurisdictions where cars are not as central to life.

Blitter posted:

What the gently caress? Is someone forcing you to go out somewhere with a car, get drunk, and then drive?

If driving is central to your life, how about not endangering that by driving drunk? How would harsh penalties increase infractions? Who gives a gently caress if some shitheel who somehow was unable to avoid a DUI now gets caught driving without a license and gets jailed. Oh no! Consequences!!

I mean, I get that living in a lovely country like the US with less medical aid/addiction treatment doesn't make it easy for low income alcoholics but what's the answer? Give people a pass on loving murder?

People take a rational thought: "I probably won't be caught," and mix it with a totally irrational weighing of the consequences. That's just human nature and we are stuck dealing with it. The reality is that justice and effective public policy aren't always 1:1. It might be just to punish people more harshly for a given crime, but that doesn't mean it creates the best outcome for society.

I guess the idea is that, besides punishment, it's preferable to actually stop people from driving drunk. Jail works well enough for that but it's not a long-term solution.

If you've got a dude somewhere with no public transportation to get him to work and you put a device on his car that makes it very difficult to drive drunk, then most likely he will be driving sober. If you take away his license then he may continue driving anyway in order to work, and will probably be doing so drunk.

Exactly. The concept pervades workplace safety as well.

I worked as a mail-handler for USPS for four months in 2000 (worst job I ever had). I usually sorted SPBS junk mail but I would sometimes get called off to help unload trucks when they fell behind. Usually they were full of filthy, noxious smelling mail bags, but one day it was a truck full of computers. I can't remember if it was Gateway2000 or Dell but it was obvious what we were unloading and back then even basic PCs were still really expensive. We unloaded those boxes exactly as if they were mail bags, just throwing the boxes 10 or 15 feet the tall mail carts. You could hear stuff breaking and I'm looking around because I feel like this isn't okay but nobody gave a poo poo; just unload as fast as possible and move on.

I ended up leaving that job after I started to get repetitive stress injuries and was literally told that they would just fire me instead of giving me a wrist brace.

This happened at a building I used to run, but the opposite direction. The night cleaning crew put a backpack vacuum on the elevator and then moved to unplug it, but they were too slow. The elevator doors closed and the car went down, pulling the cord some ways before getting to the plug which caused the vacuum to smash into the elevator ceiling. The plug end broke and the loose wire in the shaft snagged in the door hardware and the elevator car got stuck between floors.

The best part is they didn't mention this to anyone. I got to work in the morning and found an elevator out of service. I called our mechanic who found the car location and opened the lobby doors to reveal 20 feet of SJ wire tangled in the door operator. We looked at each other and just sighed. I had to tell the night cleaning supervisor to have the "poo poo happens; I won't get mad, just tell me when it does" talk with his people.

The hard styrofoam (EPS) bike helmets are single use and designed to fracture with a significant impact. On a hard crash they will really break, though the plastic shell often holds them together, but they can explode dramatically too.




There are also multi-impact helmets that use polypropylene (EPP) or other softer materials that shouldn't break apart. They're often sold for use in sports where you're expected to fall.

Maintenance and cleaning folks know that people will move your "restroom closed" signs with no hesitation, including wheeling work carts out of the way so they can squeeze past. I once had a woman come into a restroom in a food court where I had a toilet off the wall and a K-50 in the drain. I told her the bathroom is closed and she should use the other one 50 feet away, but she said she "just had to go." It didn't seem to faze her when I told her she was wading in 2 inches of raw sewage either, so I guess she really had to go.
