Anyone know what chemicals they had that had to be kept cool? Someone mentioned various organic peroxides earlier, but I'm looking for more details.

every niosh face report is a frozen tragedy, analyzed from every direction, pinned in place with needles of protocol, fixing it to the backing board by the steps that could have been taken to prevent a worker''s death. dozens of tragedies lain side by side, neatly categorized, in a table, assigned numbers. no written safety protocols. no guardrails. inadequate training. safety interlocks disabled. no confined space permit. inadequate breathing apparatus. no incident management procedure. the worker was told by his boss to ignore procedure in order to save time. the worker climbed into the machine to free the mechanism. over and over and over again, the same deaths play out in different and novel and hideous ways, taking a new life each time.

NIOSH does what it can, and in the end, that is figuring out what went wrong, and tweeting photos of incident areas, cleaned off enough to make them palatable, with cordoned off machines that tore a man to shreds, and spaces in which a man took his final, toxic breath.

Is ladder logic still heavily used or have engineers moved on to "real" languages?

Am I the only one noticing that the direction the tracks are rotating are the same direction he's running, making this either a great optical illusion or fake as poo poo?

Anyone asking for matchmaking for raids apparently has not played the Echo Chamber strike with regular folk. Moving a ball to another place before being able to shoot at the boss is just too much for a regular person to handle when they just want to run through a level, shoot dudes and get some stuff.

I was playing through Half-Life again and I keep ticking off in my head all the things you have to do to progress that are massively stupid. I lost count of confined space entries by the time the marines showed up.

It's all above board, the hazard suit is the ultimate PPE.

quote:

“I don’t want the public thinking these are massive explosions,” Royall told reporters. Attempting to explain why the plant operator called them explosions while local authorities did not, Royall said: “We’re on the same page. It’s a matter of terminology. I call it a chemical reaction and an overpressure of the container.”

Gonzalez, the sheriff, said at a news briefing that the fumes created by the chemical reaction are “not anything toxic; it is not anything that we feel is a danger to the community at all.”

But federal authorities used dire language to describe the impact of those fumes: The chemical plume in Crosby is “incredibly dangerous,” William “Brock” Long, administrator of the Federal Emergency Management Agency, said at a briefing Thursday morning.

The plant in Crosby manufactures organic peroxides, a family of compounds used in everything from pharmaceuticals to construction materials such as counter tops and pipes.

Whoops. Totally posted in the wrong thread. Thats what I get for phone posting on the toilet.

Newer stuff allows you to combine ladder with things like structured text and function blocks. Ladder logic is still very useful because it's very easy to program and understand. The problems is that as you want to do more complicated stuff it can get clumsy.

Also with some of the software you can make changes while the system is live, not turning the PLC into PROGRAM mode, programming, and then back to RUN mode, but you have to be extremely careful.

Also there are companies that aren't using PLCs as much and are more working with Distributed Control Systems, or DCS. If you have a small factory and a couple of standalone machines or a small assembly line, PLCs work great. If you are running an oil refinery, public utility, or power plant, you will have some PLCs but also a larger DCS network. We're talking about combining:

• Remote I/O (input/output) devices
  
• Networked PLCs
  
• Floor HMI (human/machine interface)
  
• Control room operation controls
  
• Alarm management and response
  
• Process monitoring and statistics
  
• Resource monitoring (electricity, fuel, raw materials)
  
• System security
  

It can get really complicated.

idgi. Did they purposely overinflate that tire to burst just to show off the cage?

Differing points of view

Arkema (in Houston flood): We had "two explosions followed by black smoke".
Harris County sheriff: We had a "series of chemical reactions"; he also referred to them as "a series of pops".

The company is doing the responsible thing (for now) reporting the truth, warning of more to come and telling people to get out?! The local government is playing trying it down as nothing while looking like complete idiots? Never thought I would see that combination.

It occurs to me that the sheriff is trying to prevent mass flight in an area it's currently impossible to evacuate due to flood. He still needs more practice in lying.

It's very considerate to put ready-made shrapnel around the cage in case it failed.

Ladder logic is pretty rigorous, redundant, and easy to read if you adhere to proper coding

I would never let a computer scientist ever touch code for something used in manufacturing

Arsenic Lupin posted:

Yeah, but I'm betting that the people who actually run the plant have a better understanding of whether it was an explosion than the local sheriff does. Unless he's a retired chem eng or something.
