**Thermal runaway prevention** refers to the design strategies, controls, and protective measures used to stop or mitigate a self-accelerating increase in temperature within a system, where rising heat causes reactions or conditions that generate even more heat, potentially leading to failure, fire, or explosion.
It commonly includes methods such as temperature monitoring, cooling systems, material selection, circuit protection, process controls, and safety shutdown mechanisms, especially in batteries, electronics, chemical processes, and energy storage systems.
