Hazmat class 1 pertains specifically to explosives. This classification includes substances and items that are capable of creating an explosive reaction, such as dynamite, fireworks, and other materials that can undergo a rapid chemical reaction leading to a release of gases, heat, and sound. The handling and transport of these materials are governed by strict regulations to ensure safety due to their potential to cause significant harm.

The relevance of proper classification is crucial for ensuring that individuals who transport or handle hazardous materials are aware of the associated risks and necessary precautions. Understanding the nature of explosives and the implications of their transport helps in mitigating risks associated with their handling.

In contrast, other classes refer to different types of hazards: corrosive substances can cause corrosion or damage to living tissues and materials; flammable solids can ignite easily and burn vigorously; while radioactive materials emit radiation that can pose health risks. Each of these classes has its own specific handling and storage requirements to ensure safety in their respective contexts.
