Modifies provisions relating to commercial outdoor fireworks displays

HB 2104 requires permits from the state fire marshal or local fire authority for any commercial outdoor fireworks display or event with a crowd (e.g., at fairs, parks, or concerts). It mandates that permits be applied for at least 10 business days in advance, require licensed operators on-site following national safety codes (NFPA 1123/1126), and demand proof of financial responsibility for property damage or injuries. The bill also requires pre-event inspections for safety compliance and applies only to commercial displays, exempting private, non-commercial events (which need only 5 days' notice to local authorities). This bill directly affects businesses, venues, and event organizers hosting public fireworks shows in Missouri.
