SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention.
Remove contaminated clothes.
Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer for medical attention.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms/effects, acute and delayed
Excerpt from ERG Guide 124 [Gases - Toxic and/or Corrosive - Oxidizing]: TOXIC; may be fatal if inhaled or absorbed through skin. Fire will produce irritating, corrosive and/or toxic gases. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Runoff from fire control may cause pollution. (ERG, 2016)
Indication of immediate medical attention and special treatment needed, if necessary
For immediate first aid: Ensure that adequate decontamination has been carried out. If victim is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep victim quiet and maintain normal body temperature. Obtain medical attention. Fluorine and related compounds
SECTION 5: Firefighting measures
Suitable extinguishing media
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Keep run-off water out of sewers and water sources. Do not apply water to point of leak in tank car or container.
Specific hazards arising from the chemical
Excerpt from ERG Guide 124 [Gases - Toxic and/or Corrosive - Oxidizing]: Substance does not burn but will support combustion. Vapors from liquefied gas are initially heavier than air and spread along ground. These are strong oxidizers and will react vigorously or explosively with many materials including fuels. May ignite combustibles (wood, paper, oil, clothing, etc.). Some will react violently with air, moist air and/or water. Cylinders exposed to fire may vent and release toxic and/or corrosive gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket. (ERG, 2016)
Special protective actions for fire-fighters
In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep cylinder cool by spraying with water. NO direct contact with water. Combat fire from a sheltered position.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Evacuate danger area! Consult an expert! Personal protection: gas-tight chemical protection suit including self-contained breathing apparatus. Ventilation.

SECTION 10: Stability and reactivity
Reactivity
The substance is a strong oxidant. It reacts with combustible and reducing materials. Reacts with many materials, for example non-metals such as red phosphorous and boron powder and porous materials such as silica, alumina and charcoal. Contact with steam causes explosion.
Chemical stability
Gas may be kept over water unchanged for a month
Possibility of hazardous reactions
The gas is heavier than air.OXYGEN DIFLUORIDE is an oxidizing agent. Mixtures with carbon monoxide, with hydrogen, or with methane explode on sparking [Streng, A. G., Chem. Rev., 1963, 63, p. 610]. May react explosively with adsorbents (silica, alumina, molecular sieves, silica gel) [Streng A. G., Chem. Eng. News, 1965, 43(12), p. 5]; the presence of moisture may render such mixtures shock-sensitive [Metz, F. I., Chem. Eng. News, 1965, 43(7), p. 41]. Gives explosive reactions with diborane, hydrogen sulfide, nitrogen oxide, nitrosyl fluoride, charcoal, sulfur tetrafluoride. Warming of mixtures with halogens, with metal halides, with aluminum chloride, with antimony pentachloride, and with tungsten gives explosions. Ignites on contact with diborane tetrafluoride, phosphorus pentaoxide, red phosphorus, boron, silicon [Bretherick, 5th ed., 1995, p. 1419]. Incompatible with ammonia, arsenic trioxide, chromium trioxide, chlorine in the presence of copper, ozone [Lewis, 3rd ed., 1993, p. 978]. Reacts to incandescence with aluminum, barium, cadmium, magnesium, strontium, zinc, zirconium. Reacts with the alkali metals (lithium, sodium, potassium) [Streng, A. G., Chem. Rev., 1963, 63, p. 611].
Conditions to avoid

Other Information
Do NOT take working clothes home.The occupational exposure limit value should not be exceeded during any part of the working exposure.The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.
