What information is indicated by the ejection of a red disk from a thermal discharge indicator?

The ejection of a red disk from a thermal discharge indicator signifies that the container contents have been dumped overboard. This mechanism is designed as a safety feature, signaling potentially hazardous situations where the temperature in the container has exceeded a critical level, prompting an automatic release of the contents to prevent further risks, such as fire or explosion.

This process is vital in ensuring that equipment remains operational within safe temperature thresholds. The red disk serves as a visual alert to operators that an emergency release has occurred, indicating immediate action may be necessary to address the conditions that led to this event. Knowing that the contents have been ejected helps in assessing the situation and determining if there is a risk of fire elsewhere in the system. Other options, while relevant to various operational conditions, do not correctly interpret the safety indication provided by the red disk.
