872: The Landfill Explosion That Changed Tesla’s Fire Strategy
SunCast
How a Powerwall Truck Crash Triggered a Landfill Explosion
Nico asks about the overturned Powerwall truck and Kathleen explains delayed thermal runaway that caused a landfill explosion days later.
A Powerwall delivery truck flipped. No fire. No smoke. Seemed safe.
They tossed those Powerwalls into a landfill. Four days later—explosion!
That incident didn’t just make headlines; it changed Tesla’s fire strategy. In this Tactical Tuesday, retired Battalion Chief Kathleen McCaffery explains how that one mistake led Tesla to create a Global Fire Liaison role—and why every developer, EPC, and AHJ should borrow the playbook.
Kathleen walks through the real science of lithium-ion incidents and the simple operational changes that stop projects from turning into disasters. It’s short, practical, and built for people who build.
This episode is a rare peek behind the curtain of Tesla Energy’s fire safety strategy—and a must-listen for developers, installers, and fire safety professionals building battery storage projects in 2025 and beyond.
You’ll learn:
🔹 Why lithium-ion fires can reignite days later (delayed thermal runaway)
🔹 Why the old rule “big fire, big water” fails—and what to do instead
🔹 How misting/cooling tactics cut water use and cleanup time
🔹 What Tesla got right (and what most companies still get wrong)
🔹 A real-world miss that destroyed a facility—and how to prevent it
From Australia’s mega sites to small-town stations, Kathleen’s job was to bridge battery tech and fire ops. Steal the lessons—and save yourself time, money, and a lot of risk.
