This episode discusses interlocks in general, and also the application of interlocks to train safety. Britain’s worst rail disaster, Quintinshill, is used to illustrate a common pattern in blaming lack of human vigilance and slow adoption of technology for the same accidents.
This episode dives into the background of the Columbia Space Shuttle Disaster. It also discusses the aftermath of a US Marine Prowler hitting a cable in the Italian Alps.
Ron returns to ask the question “Which causes more accidents: unsafe conditions, or unsafe behaviors?” Once he’s finished unpacking the question, you still won’t have an answer, but hopefully you’ll have some better questions to ask.
This episode describes the USS Iowa explosion, the subsequent investigation, and the dangers of hindsight analysis.
This is the third episode of Ron Gantt’s “Two Cents Worth of Safety”. Ron discusses the use of safety slogans, in particular the hidden messages behind the overused “Safety is Everyone’s Responsibility”.
This episode takes a new look at the really big safety question – “Why do accidents happen?” We discuss how different answers to this question lead to different approaches to safety, where common language hides fundamental differences in safety thought and technique.
This is the second “Two Cents Worth of Safety” by Ron Gantt. Regular DisasterCast has been slightly delayed, and will be back next week. In this episode Ron describes Behavioural Observation programs, along with their benefits and drawbacks.
This is the first episode of “Two Cents Worth of Safety”, which will interleave with the regular DisasterCast episodes. In this installment Ron explains how looking backward we see a whole lot more change in our lives than looking forward, and describes his own changing understanding of safety.
This is an episode about large piles falling over. We start with the physics of sandcastles, and move quickly to the coal tip at Aberfan. This leads further to discussing hindsight explanations for accidents. The episode also includes a brief review of John Templer’s “The Staircase”.
The NTSB has released a report examining common organisational factors in five accidents on Metro North Railroad in and around New York. Do five accidents in a short space of time indicate an unusual safety problem? Are there useful lessons to be learned beyond examining each accident in isolation?
