A few episodes ago I called for better communication in fire safety. And in this episode, tunnel fire safety legend Prof. Arnold Dix is answering that, by teaching us the ways of the 'sustainability' talk - how to communicate better having the global sustainability goals in mind? But it is not only a way of communication. It is a mindset. And it is a powerful one, leading to a rethink of the concept of safety and how one is delivered. A rejuvenating perspective in which we are mindful of our solutions and the goals we wish to achieve.It may be too good to be true, but then again... it is not the first time the tunnelling industry is ahead of the curve. We are still discussing how to deal with risk methods, while for a long time it is a standard approach in tunnelling. We still wonder if buildings really need to survive burnout, while tunnelling talks about resiliency. We wonder which plume model to use in our atria, while tunnelling fully embraces PBD. These are just some examples, but they really highlight how this industry is on the leading edge in innovative and disruptive ways for fire safety. I hope you will enjoy this episode. There is a lot we can learn from the tunnelling industry, that we can implement at every end of fire safety. And if you like this talk  I have good news for you! Next week, join us for part 2. Innovative approaches in transportation, how will they change our cities and the landscape of fire protection engineering! An episode not to be missed.
