Aerial luminaries which are commonly referred to as "Sky Lanterns" are prohibited for use in Frederick County, as well as, the State of Maryland.
The devices are typically constructed with oiled paper on a bamboo frame. There is a candle or a fuel cell ignited inside of the device and when the trapped air inside becomes heated, the lantern rises upward. The lanterns may travel significant distances before returning to earth and before the flame is fully extinguished. This action can result in combustibles at the landing site becoming engulfed in flames. As a result, the potential for a uncontrolled fire may occur involving a structure or vegetation.
The Code of Maryland Regulations (COMAR) Code 29.06.01.08T specifically addresses the issue of "Sky Lanterns". The code permits the prohibition of sky lanterns throughout the State of Maryland where circumstances make their use a hazard.
