What could occur if a DOT container is overfilled?

If a Department of Transportation (DOT) container is overfilled, it could cause the pressure relief valve to operate. This is a critical safety feature designed to prevent excessive pressure buildup within the container. When the container is filled beyond its designated capacity, the expanded gas can result in increased pressure. To safeguard against potential ruptures or explosion hazards, the pressure relief valve will activate, releasing excess pressure to maintain safe operating conditions.

This response highlights the importance of adhering to proper filling guidelines for DOT containers to ensure both safety and compliance with regulations, as overfilling can compromise the integrity of the system.
