These pyrotechnic articles, classified under a specific hazard division, are designed for use in professional displays and exhibitions. Their classification indicates a moderate deflagration hazard, meaning they are capable of burning rapidly but do not typically explode with mass detonation. Examples include certain types of display shells, cakes, and fountains intended for large-scale events.
The significance of these items lies in their ability to create visually impressive aerial effects and ground displays while adhering to defined safety standards. Historically, their development has allowed for the creation of increasingly complex and elaborate pyrotechnic shows. Their regulated use ensures a balance between artistic expression and public safety, contributing to the overall enjoyment of such events.
