Drysuit Diving Fatality
In 2020, a young lady, Linnea Mills, died during a drysuit diving course in Glacier National Park. There was significant anger and frustration that this event happened as it was entirely preventable. This presentation will take a systems safety and human factors approach to identify the deeper lessons that can be learned from the event.
Human nature and societal expectations mean we have a strong tendency to blame the individuals involved – if we get rid of the ‘bad apple’, everything will be fine going forward. But the science shows that if we aren’t curious and examine the system and context, the same events are likely to happen again.
Come to this presentation if you have an open mind and want to see how to make lasting changes to the sport so we increase enjoyment and improve performance, and manage operational risk, not just liability risk.
Go Diving Show 2025 takes place at the NAEC Stoneleigh Park, Coventry, on the 1st -2nd March.
