Karate Bastard posted:Can someone help me remember something correctly? Semiconductor fabs use all sorts of wonderful chemicals and gasses. Silane, Phosphine, Arsine, Diborane gas are all commonly used and want you to die and/or explode. Then you have the tanks of hydrofluoric acid that will dissolve your bones inside your body. Piranha solution for organics removal that will remove you too in short order. I know at the fab I worked with, safety was a major concern and they had gas alarms everywhere. If they went off, standard procedure was to drop everything and run as fast as you could out of the emergency exits still in your bunny suits. It meant pretty much scrapping everything in process but it was seen as a small price to pay instead of having everyone drop dead. One OSHA story from many years ago was when a tech was working under a wet bench (think a bunch of teflon sinks with chemical baths in them). He was tightening a drain fitting when it snapped off and dumped the contents of the tank on him. He runs for the emergency shower while stripping off his cloths and screaming "Litmus, litmus, litmus". He didn't know what was in the tank he was working on and thought it might be HF. Luckily, the litmus strip showed it was not acid and was just one of the rinse tanks with DI water. If it had been the HF tank he probably would have been hosed. Not sure you can get enough calcium gluconate into you to counteract getting half your body covered in HF. The tech violated procedure by working on a filled bench but it was still a wakeup call back in the days before safety was invented.

I've worked in one for about a decade now and despite all of the deadly chemicals, high voltages, plasmas and x-rays the industry is (now) incredibly safe. The number one way most workers get injured or killed? falling through an open floor tile into the subfab 20 feet below

Was friends with one of the lead utilities engineers at the 300mm chip fab I helped start up. He joked that they made sure to keep off site back ups of emergency plans for one of the main gas supply stations (I believe Silane) because a catastrophic tank failure had a high likelihood of causing other tanks to fail which could touch off a chain reaction with a 1/4mi "total destruction" radius.

Computer viking posted:Phosphine is PH3 (Phosphorous with three Hydrogens) and Phosgene is COCl2 (Carbon monoxide with two Chlorines hanging off the Carbon, kind of). They have no elements in common, so whatever you're trying to remember, I don't think it's exactly that pair.

Fun thing about fabs and litmus paper: there are a bunch of different HF-based etches around neutral pH. Won't turn litmus acidy color but will still decalcium your blood. You won't find a more well-labeled facility than a fab that's serious about safety.

That's an hilariously fake video, lol. But I appreciate the effort they took to fab up the cannon. That was cool and I'd have been happy just watching it shoot fireworks or whatever.

A warmer temperature, anyway. I’ve never used one that could heat the water to what I’d call comfortable for someone raised with proper hot running water.

Eeyo posted:Ahh good 'ol slips trips and falls I work for a company building semiconductor test equipment. A lot of this equipment still uses GPIB/IEEE-488 connections, a standard that was invented in the 1960s.  Many customers still prefer this over more modern interfaces like LAN, because when an operator trips over a LAN cable, they'll rip it out of the socket and potentially damage it. When they trip over those beefy GPIB cables, they may get hurt, but production will keep running.

We still use this in my line of work too. can confirm this is one of the reasons. Lots of our in house tech was also invented in the 1960s and we've not had much reason to change.

And here I just be eating the poo poo out of them every weekend. I should probably start appreciating all the sacrifice that goes in to my salty snack treats.

I remember a near miss at a fab that I worked on the accident report for. The tech was a new guy who was changing out a cartridge filter in the ultra pure water system. He had not actually been trained on this, and was taking initiative to do a little extra. The filter is a cylinder about the diameter of a basketball and ~3-4 feet long, located at about head height and installed so just the round end is visible. Said technician didn't properly depressurize the system, and while attempting to remove it the filter shot out and missed his head by an inch or two. One of the engineers did the math on how much force it was moving with, and it was an absurd amount I can't remember. Suffice it to say, had it hit him it would have turned all his bones into confetti and would not have been survivable.
