These pyrotechnic articles, classified as UN0336 under hazard division 1.4G, represent a specific category of display fireworks designed for professional use. These items are characterized by their relatively low hazard level compared to other classifications of explosive materials. An example includes aerial shells producing colorful bursts high in the sky during public celebrations.
Their significance lies in their capacity to deliver large-scale visual displays while adhering to stringent safety protocols. This classification allows for transportation and storage under less restrictive regulations than more hazardous fireworks, enabling wider accessibility for organized events. Historically, the development of this category has facilitated the growth of the professional fireworks industry by providing safer and more manageable products.
