Hazards and Protection.
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Wear appropriate protective gloves, clothing and goggles.
Wear positive pressure self-contained breathing apparatus (SCBA).
Attempt to stop leak if without undue personnel hazard. Do not use water.
Gas may be kept over water unchanged for a month.
Mixtures with carbon monoxide, with hydrogen, or with methane explode on sparking May react explosively with adsorbents (silica, alumina, molecular sieves, silica gel) Incompatible with ammonia, arsenic trioxide, chromium trioxide, chlorine in the presence of copper, ozone Reacts to incandescence with aluminum, barium, cadmium, magnesium, strontium, zinc, zirconium Reacts with the alkali metals (lithium, sodium, potassium).
When heated to decomposition, it emits highly toxic fumes of hydrogen fluoride.
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 use water on material itself. Do not apply water to point of leak in tank car or container.
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 explosivelywith many materials including fuels. May ignite combustibles (wood, paper, oil, clothing, etc.). Some will react violently with air, moist air and/or water. Containers may explode when heated. Ruptured cylinders may rocket.
Fire will produce irritating, corrosive and/or toxic gases.
TLV: 0.05 ppm; 0.11 mg/m3 (as CEILING) (ACGIH 1991-1992). OSHA PEL: TWA 0.05 ppm (0.1 mg/m3) NIOSH REL: C 0.05 ppm (0.1 mg/m3) NIOSH IDLH: 0.5 ppm
Drowsiness, muscular weakness, and headache have been reported. No data were available to assess the teratogenic potential of this agent. <br>No data were available to assess the potential effects of exposure to this agent during pregnancy or lactation.
Vomiting may occur.
Oxygen difluoride is highly irritating to the respiratory tract. Pulmonary edema, congestion, or lung tissue damage may occur.
It is a corrosive skin irritant. Although there are no human case reports, it is expected that this gas, under pressure, would cause serious burns.
Tearing may occur. Although no cases have been reported, the gas would be expected to cause serious burns to the eyes.
Because oxygen difluoride is a gas, there is little to no risk of ingestion exposure. Treatment should include recommendations listed in the inhalation exposure section when appropriate.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Effects may be delayed.
Remove and isolate contaminated clothing and shoes. Immediately flush with running water for at least 20 minutes. In case of contact with liquefied gas, thaw frosted parts with lukewarm water. Effects may be delayed.
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
