Which of the following describes an important safety measure while transporting hazardous materials?

Regularly checking the load and securing it properly is a crucial safety measure when transporting hazardous materials due to the risks involved. Properly securing the load helps prevent spills and accidents that could arise from shifting cargo during transport. Regular checks ensure that the load remains secure throughout the journey and that any potential hazards are addressed immediately, thus protecting not only the driver but also others on the road and the environment.

In contrast, driving at higher speeds can lead to loss of control and increases the severity of incidents in case of an accident, especially with hazardous materials involved. Neglecting to keep emergency supplies is risky as it may hinder the ability to respond effectively to accidents or spills, and relying solely on GPS for navigation might lead to unforeseen complications, such as entering an area not suitable for hazardous materials transport or encountering detours that can complicate the journey. Therefore, proper load management is fundamental to ensuring safety in these situations.
