Excerpt from ERG Guide 124 [Gases - Toxic and/or Corrosive - Oxidizing]:

CAUTION: These materials do not burn but will support combustion. Some will react violently with water.

SMALL FIRE: Contain fire and let burn. If fire must be fought, water spray or fog is recommended. Water only; no dry chemical, CO2 or Halon®. Do not get water inside containers. If it can be done safely, move undamaged containers away from the area around the fire. Damaged cylinders should be handled only by specialists.

FIRE INVOLVING TANKS: Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Do not direct water at source of leak or safety devices; icing may occur. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks in direct contact with flames. For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn. (ERG, 2024)

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.

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.

If fire becomes uncontrollable or container is exposed to direct flame, consider evacuation of one-third (1/3) mile radius.

Wear positive pressure self-contained breathing apparatus when fighting fires involving this material.

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· Keep unauthorized personnel away.

· Stay upwind, uphill and/or upstream.

· Many gases are heavier than air and will spread along the ground and collect in low or confined areas (sewers, basements, tanks, etc.).

· Ventilate closed spaces before entering, but only if properly trained and equipped.

· Do not touch or walk through spilled material.

· Keep combustibles (wood, paper, oil, etc.) away from spilled material.

· Stop leak if you can do it without risk.

· Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material.

· Do not direct water at spill or source of leak.

· If possible, turn leaking containers so that gas escapes rather than liquid.

· Prevent entry into waterways, sewers, basements or confined areas.

· Isolate area until gas has dispersed.

· Ventilate the area.

Excerpt from ERG Guide 124 [Gases - Toxic and/or Corrosive - Oxidizing]:

IMMEDIATE PRECAUTIONARY MEASURE: Isolate spill or leak area for at least 100 meters (330 feet) in all directions.

SPILL: See ERG Table 1 - Initial Isolation and Protective Action Distances on the UN/NA 2190 datasheet.

FIRE: If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions. (ERG, 2024)

Immediate precautionary measure

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

PROCESSES /WITH/ ... POTENTIAL EXPOSURE HAZARD SHOULD BE EQUIPPED WITH LOCAL EXHAUST VENTILATION. ... WORKERS SHOULD NOT CONSUME FOOD OR BEVERAGES IN THE WORKPLACE AND RIGOROUS PERSONAL HYGIENE SHOULD BE OBSERVED BEFORE MEALS ARE TAKEN. /FLUORINE AND FLUORINE COMPOUNDS/

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

If material not involved in fire: Attempt to stop leak if without undue personnel hazard. Do not use water.

Avoid breathing vapors. Keep upwind. Avoid bodily contact with the material. Wash away any material which may have contacted the body with copious amounts of water or soap and water.

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].
