Fire safe cigarettes, abbreviated "FSC", also known as lower ignition propensity (LIP), reduced fire risk (RFR), self-extinguishing, fire-safe or reduced ignition propensity (RIP) cigarettes, are cigarettes that are designed to extinguish more quickly than standard cigarettes if ignored, with the intention of preventing accidental fires. In the United States, "FSC" above the barcode signifies that the cigarettes sold are fire standards compliant (FSC).
