When are flammable materials particularly dangerous during shipping?

Flammable materials pose a significant danger at any point during shipping if they are not properly marked. Proper labeling is crucial for ensuring that everyone involved in the transportation of these materials is aware of the potential hazards. Incorrectly marked or unmarked flammable materials can lead to accidental handling, exposure to ignition sources, or poor emergency response in the event of an incident, thereby increasing the risk of fire or explosion.

In comparison, while specific situations such as loading, transportation through water, or handling at the destination may present risks, the overarching concern is that risks can arise at any point during the shipping process. Therefore, adequate marking and communication about the presence of flammable materials throughout the shipping journey are essential to maintaining safety.
