The MSDS on Fluorine Excimer Laser Mix [0] lists fluorine at less than 1% concentration, and includes the note on reactivity: it produces some liquids that shouldn't persist in the air, these aren't CFCs. Guess it depends on the quantity but sounds like a rare event. > Reactivity Hazards: Due to the presence of Fluorine, this gas mixture may react with water or moisture in the air to form hydrogen fluoride or hydrofluoric acid, plus small amounts of ozone, hydrogen peroxide and oxygen fluoride.
