How large must the warning label be printed?

The requirement for the size of the warning label in NFPA 1123 specifies that it should be at least 9 square inches. This size is designed to ensure that the information is clearly visible and legible to those handling fireworks and involved in their display. The purpose of the warning label is to convey crucial safety information and hazards associated with the handling and use of fireworks effectively. By adhering to this minimum size, the label increases the likelihood that individuals will notice and recognize the necessary precautions, thereby enhancing safety during fireworks displays. Proper labeling is critical in promoting awareness of potential dangers, which is a key aspect of effective risk management in pyrotechnics.
