Wittenoom

With demand for Asbestos in building products in the 1940s, a discovery in Western Australia's remote Pilbara region of Blue Asbestos led to the creation of a mining town called Wittenoom. Despite the growing list of illnesses and deaths of workers from the mine and milling operation, the company pressed on until it closed for 'financial' reasons. We look at the dangers of dust inhalation and try to determine if we have collectively learned anything from the disaster at Wittenoom.With John Chidgey.News Articles: Memories of Wittenoom Exposure to Asbestos Takes Its Toll CSR Still Fighting Closure of Wittenoom Wittenoom Riddled with Asbestos About Asbestos: Asbestos The Colours of Asbestos What Is Asbestos and Where Does it Come From?

Carnival Triumph

A leaking flexible pipe started a fire in the Engine Room aboard the Carnival Triumph during its return journey from Mexico in early 2013. The fire caused minor damage in one, very important section of the Engine Room leading to a total loss of Mains Power. With only intermittent Emergency Power and over 4,000 people on board the ship drifted with the currents before it was tugged finally to safety. The Netflix Documentary 'Poop Cruise' looked at the human consequences...we dive into the engineering design that was inherently flawed from Day One.With John Chidgey.Formal Report: BMA Investigation Report (PDF) News Releases and Articles: Carnival Cruises issues statement Carnival Triumph set sail with problems Stricken cruise ship docks How Poop Cruise Crisis Reshaped Cruising General Information: Trainwreck Poop Cruise (Netflix) Failure Domain Cruise Lines International Association Understanding Cruise Passenger Rights Support Causality on PatreonEpisode Gold Producers: 'r', Steven Bridle, Kellen Frodelius-Fujimoto and Steve Branam.Episode Silver Producers: Mitch Biegler, Shane O'Neill, Jared Roman, Katharina Will, Chad Juehring, Ian Gallagher and Jamie Russell.

West Gate Bridge

Planned for nearly a century, when the time came to build a permanent link across the Lower Yarra River, a relatively new style of bridge, the box-girder, was chosen. Using new computer technology assisting the engineers to design a bridge that was too complex to calculate by hand, and using a unique lifting strategy promised time and cost savings. Ultimately though when the pieces didn't fit together in the air, their attempts to make them fit, didn't work. We dive into what went wrong on Australia's largest ever industrial disaster.With John Chidgey.Formal Report: Victorian Royal Commission Report (PDF) Milford Haven Incident: Cleddau Bridge disaster General Information: Kentledge West Gate Tunnel Slide rule Box girder bridge Cleddau Bridge Widening the West Gate Freeway Melbourne October 15 Weather The West Gate Bridge Memorial Robbo Bennett’s Tribute How the West Gate Bridge collapse changed Melbourne 1970 West Gate Bridge Disaster West Gate Bridge Image Gallery The West Gate Bridge Collapse West Gate Bridge Under Construction, 1969 Support Causality on PatreonEpisode Gold Producers: 'r', Steven Bridle, Kellen Frodelius-Fujimoto and Steve Branam.Episode Silver Producers: Mitch Biegler, Shane O'Neill, Jared Roman, Katharina Will, Chad Juehring, Ian Gallagher and Jamie Russell.
