Causality

Chain of Events. Cause and Effect. We analyse what went right and what went wrong as we discover that many outcomes can be predicted, planned for and even prevented.

Great podcast for safety practitioners and risk managers.

Really enjoy John’s analysis of these famous safety incidents. Lots to learn here!

Love it

A wonderful podcast. Loving it!

A True Favorite

I discovered this podcast in a roundabout way investigating Chernobyl & Fukushima. John Chigdey is a passionate genius, I love his delivery, knowledge and analysis. I have never heard of many of these incidents (NOT ACCIDENTS!). It's tragic how these mistakes pile up on each other until the inevtiable happens. Everything seems so safe and reliable until it doesn't. Even if you're not an engineer or a scientist this is a must listen series. I listened to them all pretty much straight in a row. There are lessons here applicable to just about every part of life.

Fukushima

Great podcast. Just finished Fukushima and it’s amazing the amount of misinformation put out by other podcasts that talk about this incident. It’s great to get an engineering perspective on what happened. Keep up the great work.

Fascinating take on the world.

Horrible incidents, but extremely compelling listening

John does a wonderful of walking through and unpicking the incidents discussed. His expertise in control systems and how they factor into unfolding events make this a must listen for anyone with an interest in engineering matters. Keep listening and pay attention.

Great!

Thank you this is such a great resource for safety professionals; well researched and easy to listen to.

Best podcast i've ever listened to

I am entirely fixated on disasters, and this is by far my favorite source. Clean covering, professional with a well of barely hidden rage at the powers that be that allowed these disasters to come to fruition, and a nice voice to boot. If I could give more stars I really really would.

One of those Exceptional Podcasts

This is one of the few podcasts where the podcaster understands what the word thorough means. No useless information is ever added. The subjects are interesting, heavy, and important. Sometimes it is dry, in the sense he is not making jokes, but that is a positive thing for this podcast but does mean it is not always the most accessible. I’m sure the podcaster knows this as he (to my glee) includes undiluted technical information to help explain the event.

Dreamy narrator

This is a great podcast for me when I need a break from true crime. He talks about cataclysmic events not simply for the morbid entertainment, but to think about the “HOW” and “WHY” factors from the perspective of an engineer. Also, the dreamy Australian voice and calming tone of the narrator is everything. It’s oddly a compliment, but when I need to fall asleep to something that won’t give me nightmares in the way many others of the same genre might— he’s my guy!

Great podcast!

As a teacher, I’ve found this podcast extremely valuable in learning great examples of why physics is important in our daily lives. He’s done a wonderful job in the recap of events and then the breakdown of where things went wrong. I highly recommend this podcast!

Please make more

I enjoy having someone with a more analytical brain talk about what went wrong and why. Too many podcasts focus on the horror of what happened in disasters, as opposed to the causes beneath it. Or they focus on being entertaining and witty. I’d much rather hear someone with a background in science go through cause and effect, and what happens when people and systems fail. For a non scientist such as myself, it’s lovely learning how someone with, I assume, education and training in engineering, perceives man made disaster Great job to everyone involved in this podcast!

How things go wrong

Great analysis of various disasters. Fascinating how greed has become one of the main villians in these disasters.

From a maintenance perspective amazing

I am a maintenance electrician and it is so interesting how incorrect procedures or “tribal learning” leads to dangerous outcomes

vinnievroom
I actually get a bit excited when a new one comes out.

A podcast for those with a brain

really interesting

This podcast is awesome. Really interesting details explaining disasters from an engineering point of view.

Drew Stephens
Wonderfully in-depth explanations by an engineer

John explains the causes of disasters in great detail—many of them about incredibly interesting events that I did’t even know about.

In 1911 in Manhattan, New York, a clothing factory went up in flames just before closing time. We look at how faulty equipment, poor design and a fear of theft contributed to a wholly preventable incident that had such terrible consequences, but would trigger reforms that still impact the United States, a century later.

The original Royal Canberra Hospital was flagged to be demolished in 1997 to make way for the new National Museum. A demolition via implosion was selected, but the implosion resulted in an explosion instead, and debris showered the huge crowd of onlookers with fatal consequences.

The university wanted a bridge for its students over a busy roadway that would appear intriguing from afar. Instead it collapsed before it was even finished. We look into how design errors, poor peer review and denial led to a collapse that claimed six peoples lives.

Episode 39: Therac-25

23 March, 2021

The successor to the Therac-6 and Therac-20 RadioTherapy machines would integrate the powerful DEC PDP-11 mini-computer to control all of the Therac-25s functions, including the safety interlocks, for the first time. In two years the 11 machines in service would overdose six people across two countries, killing three of them before they figured out why.

A popular family-friendly ride at DreamWorld would claim the lives of four people in 2016. In nearly thirty years of operation the ride had several similar but non-fatal incidents with blame placed on the operator every time, when a three thousand dollar modification could have prevented a horrific incident.
