When I first graduated, I worked on projects for Individual plant examination (IPE) of nuclear plants (NRC in Generic Letter 88-20, -Individual Plant Examination for Severe Accident Vulnerabilities-) which included the interconnection of components, their probability of failure, Human Factors (e. g. too many alarms, controls out of reach, in unsafe places, etc) and the calculating resulting consequences (from shutdown to full catastrophic releases. I hope that all technological items are put through such rigors. I am not assured that the AI and IT areas have that kind of safety culture yet where -hurry up until it breaks- seems to be the norm. In this information era, such things could be just as catastrophic as Three Mile Island many times over.

As someone who holds his degree in finance, I'm learning more about other fields for my own edification. It's funny you mention safety and nuclear engineering. As a final requirement to achieve an award at the public speaking organization Toastmasters, I am mentoring a new club at a nuclear power plant and I have never met more anal-compulsive people in my life regarding rules.
Considering a catastrophic mishap at their job could wipe out half my state of New Jersey, I shouldn't be so glib. On second thought, considering the last catastrophic mishap in MY industry nearly destroyed the entire world economy, I -really- shouldn't be so glib.

You're wrong about the reasons for the Chernobyl disaster, you should've really researched it more before making such statements.
Also the death toll is much higher, not to mention that any estimates given by the ussr at the time are highly inaccurate as the government would do literally anything to hide the damage as much as possible.
Plus, beside the direct deaths, there's a huge on going health impact on millions of people. Everyone born west of Chernobyl (that was the wind direction) around that time, even a country over, is still monitored for and often develops thyroid related problems.

Interesting fact, we still have many of the exact same Chernobyl reactors operating around the world, 11 at last counting. We made them safer by increasing the enrichment of the fuel, thus, allowing for more negative control rods in the reactor at the same time, better instrumentation, and other features and training that make them just as safe as other, modern reactors.
Just goes to show that safety is more about systems design and culture than just -bad apples-. Even this so called troubled reactor can and has been made safe to modern standards. Cheers.

Something else I wish they had mentioned is -alarm fatigue- which can be a big problem for medical professions in hospital settings. Alarm fatigue what happens when you hear an alarm, no matter how important it is in the individual instance, so often that your brain starts to lower its priority in your attention until you eventually can't really hear it at all. In a more commonplace example, you might set a song as your wakeup alarm sound, but after a while, it stops waking you up as quickly and you have to pick a new one.

-_. when UAL#173 dry-tanked a couple miles short of Portland Oregon Dec. 1978, the NTSB put the blame on the Pilot not paying attention-probably because the Pilot said 'a word' to reset the 'missing-something-thinking' his crew was experiencing (why-the-dry-tanks, but NTSB never considered the inconvenient truth causing the unsafe-readings on the panel. _-

My husband worked at a farm, and farmers can be a bit slapdash about safety (if you know farmers, you know they don't have 10 fingers, on average. One time he pulled open a control panel to do some tinkering and was greeted by a sign, a metal sign bolted onto the wall where he was going to be tinkering: -Really now, have you read the instructions? -

-_. lacks the concept of Systems Theory, not just severities of faults but the dynamics of amplification, exponents, modes, magnitudes, definitions, rapidity and fragmentation of reports and changes, interactions of remedies. 2. lacks caution for the sources of safety equipment, e. g. military surplus specialized for high casualty rate zones. _-

Shes complitely wrong about Chernobyl- much more than 100 or even a thousand people died there and a whole city, which was unexpectedly evacuated was infused with radiation as well as rivers and fields nearby(things like purple trees and two-headed dogs or six-eyed fish started to happen!

You can work and research safety in any engineering field, each one focused on their own area, e. g.:
Chemical and Mechanical Engineers: Process Safety
Civil Engineers: Construction Industry
Electrical Engineers: Electrical Engineering Safety
