Lighters

Abstract

Lighterssyn. gas candles are small mechanical or electrical flame-producing devices for igniting fuels, fires, cigars (rolls or tobacco wrapped in tobacco leaf), cigarettes (rolls of tobacco wrapped in a non-tobacco product such as paper), and pipes (devices used to burn and inhale tobacco). Electrical devices operate by generating a spark between two conductors as they are introduced into a fuel source; unless battery-powered, they have no internal fuel source of their own and do not represent a hazard in transportation. Other lighters, like cigarette lighters, contain a reservoir of lighter fluid, a liquefied flammable gas such as propane or butane, a valve, and an ignition device. Lighters may also contain pyrophoric liquids that do not require an ignition system but ignite when exposed to air. Some lighters are disposable, while others may be refilled or have their igniter fluid cartridge replaced.
