Which of the following is NOT a requirement for transporting dangerous goods?

The requirement regarding personal protective equipment (PPE) for all personnel is not specifically mandated for the transportation of dangerous goods. While the use of PPE is crucial during handling and in certain situations where exposure risks are present, it does not directly pertain to the transportation process itself.

In contrast, proper labels and markings on containers, placards for vehicles, and shipping documents are essential requirements designed to ensure safety during the transport of dangerous goods. These items communicate hazards clearly to personnel involved in the transportation process and to emergent responders, thereby facilitating safe handling and emergency measures if necessary. Proper labeling and documentation help to identify the nature of the goods, informing others of the associated risks and how they should be managed.
