HAZMAT CDL Practice Test

What characteristic does Hazard Class 1.5 describe?

1. Very Insensitive - Blasting Agents

2. Minor Explosion

3. Fire Hazard

4. Mass Explosion

The correct answer is: Very Insensitive - Blasting Agents

Hazard Class 1.5 is specifically designed for very insensitive explosives, which are classified as blasting agents. These materials require a high-energy detonator to initiate an explosion, making them safer to handle and transport compared to other types of explosives. This characteristic of being "very insensitive" indicates that while they can be explosive under certain conditions, they are less likely to explode unintentionally or due to shock, heat, or friction. In contrast, other hazard classifications denote different sensitivity and risks: for example, a minor explosion implies a greater potential for unintentional detonation, while fire hazard and mass explosion pertain to materials with varying explosive qualities and risks associated with fire or large-scale detonations. Understanding the specific definition of Hazard Class 1.5 helps ensure safe handling practices for materials within this category.
