Which aspect is NOT covered by TDG regulations?

The correct choice highlights that TDG regulations do not encompass marketing strategies for hazardous materials. TDG is primarily focused on the safe transportation of dangerous goods, which includes specific guidelines on packaging, handling, storage, and procedures during loading and unloading.

TDG regulations are designed to ensure that dangerous goods are transported safely, protecting both the public and the environment. This includes strict standards for packaging to prevent leaks and spills, detailed procedures for the safe handling and storage of such materials to minimize risks during transportation, and defined protocols for loading and unloading to ensure safety at transport hubs.

In contrast, marketing strategies pertain to how companies promote and sell their hazardous materials. This aspect does not fall under the purview of TDG regulations, which aim to manage the physical risks associated with the transportation of dangerous goods rather than the business practices related to their sale and promotion.
