Catastrophes don’t happen because of one bad decision; they happen when many small assumptions fail at the same time. I take this opportunity to talk about my thoughts related to the Wang Fuk Court fire in Hong Kong. I attempt to examine how a routine ignition escalated into hundreds of compartment fires across multiple buildings—and what that says about the limits of our current fire engineering. Keep in mind these are the opinions of myself! 

We start by challenging a comforting belief: that prescriptive rules and performance-based designs can handle “the big one.” They can’t if the event steps outside the envelope. You’ll hear why compartment-focused strategies struggle when geometry and wind synchronize flames, how cavity spaces in light wells amplify heat and acceleration, and why nonlinearity means a modest increase in heat release can explode into a different regime of flame spread and radiation.

We break down the ingredients that turned risk into disaster: star-shaped towers with interior wells, bamboo scaffolding and netting near openings, temporary polystyrene window covers, and a dry monsoon pushing firebrands far beyond the origin. We also dig into response realities—why sprinklers and hydrants are sized for one or two compartments, not dozens at once—and the hydraulic and access limits firefighters face at height.

Most importantly, we translate insights into action. Learn how to make extreme scenarios explicit with safety cases during construction, align tests with actual exposure on façades and cavities, replace flammable temporary coverings with noncombustible barriers, and plan targeted, temporary suppression where geometry concentrates risk. No single fix will prevent every tragedy, but narrowing the gap between our models and real fire behavior can save lives and homes.

If this conversation helped you see fire risk differently, subscribe, share the episode with a colleague, and leave a quick review—what’s the most overlooked hazard you think we should explore next?

I would like to wish you a Happy New Year 2026! Let's hope it is a year of thriving fire safety.
