Pétard

Pétard is a term of French origin for a small explosive device used as a firework or signal. In everyday French usage it most often refers to a firecracker or other loud explosive employed during celebrations. The English cognate petard historically referred to the same kind of device and is now chiefly used in historical or literary contexts.

Origins and history: The device originated in medieval and early modern warfare as a small charge placed in a hollow structure or attached to a fuse to breach walls. The expression hoist with his own petard, from Shakespeare's Hamlet, reflects its sudden backfire or dangerous power in both language and culture.

Varieties and usage: In contemporary Francophone contexts, pétards describe consumer fireworks marketed for home use, typically small devices that emit a loud report and a flash. They are part of the broader category of pyrotechnic devices and are regulated differently by country or region.

Safety and legality: Pétards can cause burns, eye injuries, hearing damage, and fires. Many jurisdictions regulate or ban their sale and use, especially for minors; permits, restricted times, or professional handling may be required. Users are advised to follow local laws, maintain a safe distance, and not attempt to modify or relight unexploded devices.
