What should be done with damaged shells that are irreparable?

Damaged shells that are deemed irreparable must be returned to the supplier or disposed of according to the supplier's instructions as this is a critical safety protocol. Firework shells that show signs of damage can pose significant risks if handled improperly. Manufacturers and suppliers typically have specific guidelines for the disposal of such products to ensure that they are managed safely and do not contribute to any hazards.

Returning the damaged products not only complies with safety regulations but also allows the supplier to assess the issue and improve future production processes or investigate potential defects. Adhering to this practice minimizes the risk of accidents and protects both personnel and the public during fireworks displays.

The other options, such as displaying, salvaging for parts, or reusing damaged shells, could lead to unsafe practices and are not compliant with the established safety standards outlined in NFPA 1123. These alternatives do not prioritize safety or adherence to manufacturer instructions, which are paramount in handling fireworks.
