Fluorine ignites in contact with ammonia, ceramic materials, phophorus, sulfur, copper wire, acetone and many other organic and inorganic compounds. Flush affected area with copious amounts of water for 5 minutes. Remove contaminated clothing as rapidly as possible. Continue for a minimum of 30 minutes. Seek medical attention immediately.
High concentrations can cause severe damage to the respiratory system and can be fatal.
Conscious persons should be assisted to an area with fresh, uncontaminated air. Handling Teflon is the preferred gasket material when working with fluorine gas. Keep equipment scrupulously dry. The reaction between metals and fluorine is relatively slow at room temperature, but becomes vigorous and self-sustaining if the temperature is elevated. Use only in well-ventilated areas, vented gas storage cabinets, or fume hoods.
