Investigators publish report on 2024 containership blast in China's Ningbo Port

The continuous increase in temperature accelerated the self-decomposition reaction, which then resulted in thermal runaway and the subsequent explosion and fire.

The CMSA also determined that the incident occurred during a period when summer temperatures in Shanghai, where the TBPB was packed, were higher than usual. On July 25, during the packing of the TBPB cargo, the packing temperature was consistent with the ambient temperature (about 35°C).
