Which placard must be displayed on a vehicle with moderate risk of fire?

The placard indicating a moderate risk of fire is designated as 1.4. This classification is used for explosives that present a limited hazard in terms of fire and explosion risks. Specifically, it refers to materials that can be transported without the same levels of risk associated with higher hazard classes.

This classification is relevant for safety professionals because it helps determine the appropriate safety measures, transport protocols, and risk assessments needed when handling and transporting such materials. Ensuring that the correct placard is displayed on the vehicle is crucial for compliance with regulations and for alerting others about the nature of the contents being transported.

The other classifications, such as 1.1, 1.2, and 1.3, indicate progressively higher levels of risk associated with fire and explosion hazards and are used for materials that pose a greater danger. Therefore, understanding the specific meanings of these placard classifications is vital for effective explosives safety management.
