What is the requirement for shells prior to being prepared for display?

The requirement for shells prior to being prepared for display is that they must be kept in their shipping cartons. This practice is essential for safety reasons, as shipping cartons are designed to protect the fireworks during transport and storage, reducing the risk of accidental ignition or damage. Keeping shells in their original packaging minimizes exposure to environmental factors that could affect their performance or safety, such as moisture or impact.

Additionally, this approach ensures that the fireworks are maintained in a stable condition until they are ready to be used, helping to ensure a safe and successful display. Fireworks are hazardous materials, and adhering to proper storage guidelines, such as keeping them in shipping cartons, is critical in eliminating potential risks associated with handling and preparing them for a public display.
