The Safety of Work Ep. 118 How should we account for technological accidents?
Using the Waterfall incident as a striking focal point, we dissect the investigation and its aftermath, we share personal reflections on the implementation of safety recommendations and the nuances of assessing systems designed to protect us. From the mechanics of dead man's systems to the critical evaluation of managerial decisions, our dialogue exposes the delicate balance of enforcing safety while maintaining the practicality of operations. Our aim is to contribute to the ongoing conversation about creating safer work environments across industries, recognizing the need for both technological advancements and refined human judgment.

Quotes:
“I find that some of the most interesting things in safety don't actually come from people with traditional safety or even traditional safety backgrounds.”- Drew
“Because this is a possible risk scenario, on these trains, we have what's called a ‘dead man system.” - David
“Every time you have an accident, it must have objective physical causes, and those physical causes have to come from objective organisational failures, and I think that's a fairly fair representation of how we think about accidents in safety.” - Drew
“They focused on the dead man pedal because they couldn't find anything wrong with the design of the switch, so they assumed that it must have been the pedal that was the problem” - Drew
