Modifies provisions governing fireworks

HB 806 updates Missouri's fireworks regulations by defining key terms (like "consumer fireworks" and "display fireworks"), establishing specific sale periods (June 20-July 10 and December 20-January 2), and clarifying burn ban rules. It prohibits local burn bans from restricting fireworks sales but allows bans on certain devices (e.g., "missiles" or "skyrockets" per safety standards) while permitting other consumer fireworks. The bill directly affects retailers (seasonal and annual), distributors, and display operators by setting new compliance requirements and sale windows. It replaces outdated statutes with standardized definitions aligned with industry safety guidelines (APA standards) and U.S. hazardous materials rules. The changes aim to clarify legal boundaries for fireworks use, sale, and safety during fire-prone periods.
