Use

Dinitrogen tetrafluoride is an oxidizing agent. Explodes or ignites on contact with reducing agents at normal temperatures, including alcohols, amines, ammonia, beryllium alkyls, boranes, dicyanogen, hydrazines, hydrocarbons, hydrogen, nitroalkanes, powdered metals, silanes, or thiols [Bretherick 1979 p.174]. Can explode at high temperatures. Can explode with shock or blast when under pressure. Emits highly toxic fumes of fluorine and oxides of nitrogen when heated to decomposition. Several grams of a crude mixture containing Dinitrogen tetrafluoride and nitrogen trifluoride had been allowed to collect in a stainless steel cylinder. During opening of valves to check the pressure, the cylinder exploded, killing one man and injuring another [MCA Case History 683 1966].
