How do you identify and address a potential thermal runaway condition on a loaded tank car containing hazardous materials during a pre-departure inspection?

Thermal runaway is a condition where a chemical reaction inside a tank car accelerates uncontrollably, generating excessive heat and pressure. This can lead to a tank car rupture, explosion, or release of hazardous materials. Identifying and addressing this condition during a pre-departure inspection is crucial. During the inspection, first refer to the shipping papers. The shipping papers will identify the hazardous material being transported and any specific instructions or warnings related to that material.
