What is an example of a mass explosion hazard in Hazard Class 1?

In the context of Hazard Class 1, which deals with explosive materials, a mass explosion hazard specifically refers to substances or devices that can cause a significant explosion resulting in widespread damage and the potential for multiple explosive effects. Bombs are a prime example of such hazards because they are designed to explode and can result in a massive release of energy, leading to destruction over a wide area and potentially harming anyone nearby.

Fuzes, while associated with explosive devices, function as igniting mechanisms rather than representing a standalone mass explosion hazard. Cotton does not fall under this category, as it is not an explosive material. Similarly, propellants, while they are significant in terms of explosive properties, typically do not represent mass explosion hazards in the same context as bombs do. They are more associated with propulsion rather than being designed to cause an immediate, widespread explosive effect. Therefore, bombs stand out clearly as the definitive example of a mass explosion hazard within Hazard Class 1.
