No, owning a flamethrower in Missouri is not explicitly prohibited at the state level, but local ordinances and federal regulations may restrict their use. Missouri lacks a statewide ban, yet municipalities like St. Louis and Kansas City impose nuisance or fire safety ordinances that could limit possession. Federal law under the Consumer Product Safety Act does not classify flamethrowers as hazardous devices, but their sale may trigger ATF scrutiny if modified for incendiary purposes.
Key Regulations for Owning a Flamethrower in Missouri
- Local Fire Safety Ordinances: Cities such as St. Louis require permits for devices deemed fire hazards, with violations punishable by fines up to $500. The St. Louis Fire Prevention Code (2024) explicitly references “open flame devices” as requiring approval.
- Federal ATF Compliance: While not banned, flamethrowers may fall under ATF’s regulatory purview if classified as destructive devices under 18 U.S.C. § 921(a)(4). Recent 2026 draft guidance suggests stricter scrutiny for devices exceeding 10 psi pressure.
- Public Nuisance Laws: Missouri’s Public Nuisance Act (RSMo § 537.010) empowers local authorities to confiscate devices deemed likely to cause harm, particularly in residential zones. Courts have upheld seizures in cases involving reckless use.
Purchasers must verify municipal codes and federal guidelines, as enforcement varies by jurisdiction. Consult the Missouri State Fire Marshal’s Office for updates, as 2026 amendments may introduce additional restrictions.
