    61: West Gate Bridge
    Nov 29 2025
    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.

    60: Carnival Triumph
    Aug 26 2025
    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.

    Apr 30 2025
    After an extended outage of the Methomyl Unit at the Bayer facility in Institute, West Virginia, the decision was made to commence a restart of the Unit even though the DCS upgrade was still incomplete and the newly replaced Residue Treater hadn't been fully recommissioned. An incident whose root cause was years in the making would ultimately cost two people their lives.

    58: West Fertilizer Company
    Mar 31 2025
    In the early hours of the evening on the 17th of April, 2013 in the small city of West, Texas...smoke was seen emanating from the West Fertilizer Company building. In 20 minutes there was a massive explosion that levelled the facility and its surroundings, killing 15 people and injuring hundreds more. How this came to be, represented a failure of regulations, planning and grandfathering on every level.

    56: BP Husky Toledo
    Dec 17 2024
    On the 20th of September, 2022 at the BP Husky Toledo refinery in Ohio, a level transmitter change out from a month prior triggered a chain of events that would cost two operators their lives. We look at how poor Management of Change, high alarm rates and a resistance to stopping the job, let a plant upset turn into a disaster.

    Jun 25 2024
    In 2017 during an Odoriser decontamination procedure in West Virginia, two people were killed when it unexpectedly exploded. Barely a month later, a similar procedure at the same site led to a second explosion, killing someone else. We examine how poor hazard analysis and legal interference led to yet another fatality...right in front of the eyes of the investigators on site.
