“Although they are pretty, sky lanterns are uncontrolled, open-flamed devices that pose an extreme fire hazard to people, property, and the environment” said Oregon Chief Deputy State Fire Marshal Mariana Ruiz-Temple. “Once released you have no control over where they may land. They could end up on someone’s rooftop, in a tree, or a pile of debris and cause an unwanted fire.”
A number of states, as well as countries such as Germany, Australia, and Brazil have outlawed sky lanterns. As of January 1, 2017, releasing a sky lantern into Oregon airspace will be a Class A violation subject to a maximum penalty of $2,000.
