The Safety of Work Ep.57 What is the full story behind safety I and safety II (Part 1)?
For this episode, we are breaking away from the standard formula for this show. We thought it best to split this topic into three episodes, as we don’t want to oversimplify our breakdown of this seminal, two-hundred page book.
We encourage all of our listeners to follow along and read the book with us. Join us as we dig into this influential book by Erik Hollnagel.
Topics:
- Interpretations of new theories.
- Hollnagel being the direct intellectual descendant of Professor Rasmussen.
- Chapter 1: The Issues.
- The denominator problem.
- The regulator paradox.
- The problems with defining safety.
- Overall thoughts on Chapter 1.
- What to skim and what to read closely.
