Explosive or violent reaction with organic materials|Reacts with water. Hygroscopic

Fumes in air. Reacts with water with explosive force, oxygen being evolved [Handbook of Chemistry and Physics]. HBr gas might also be produced upon reaction with water. Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Hydrogen Fluoride (hydrofluoric acid) gas will be created in 1.2 minutes. Experimental details are in the following: "Development of the Table of Initial Isolation and Protective Distances for the 2008 Emergency Response Guidebook", ANL/DIS-09-2, D.F. Brown, H.M.

Oxidizing Agents, Strong

Strong Oxidizing Agent

BROMINE TRIFLUORIDE is a very reactive oxidizing agent. Reacts violently on contact with water to evolve oxygen. Accelerates the burning of combustible material. Mixing with the following hydrogen-containing substances is likely to cause a fire or explosion: acetic acid, ammonia, benzene, ethanol, 2-pentanone, hydrogen, hydrogen sulfide, methane, cork, grease paper , wax. Mixing with acids, halogens, ammonium halides, metal halides, metals, nonmetals, or metal oxides at ambient or slightly above ambient temperatures has resulted in violent reactions. Specifically, reacts dangerously with nitric acid, sulfuric acid, chlorine, iodine, ammonium chloride, potassium iodide, boron powder, selenium, tellurium, aluminum powder, bismuth, cobalt powder, iron powder, arsenic, nickel powder, chromium trioxide, charcoal, red phosphorus, sulfur dioxide, magnesium oxide.

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.|Excess bromine trifluoride may be destroyed conveniently in a hood by slow addition to a large volume of the solvent /carbon tetrachloride/, interaction being vigorous but not dangerous.

Excerpt from ERG Guide 144 [Oxidizers (Water-Reactive)]: As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. SPILL: See ERG Table 1 - Initial Isolation and Protective Action Distances on the UN/NA 1746 datasheet. FIRE: If tank, rail car or tank truck 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, 2016)

Excerpt from ERG Guide 144 [Oxidizers (Water-Reactive)]: ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area). Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. 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 GET WATER on spilled substance or inside containers. SMALL SPILL: Cover with DRY earth, DRY sand or other non-combustible material followed with plastic sheet to minimize spreading or contact with rain. LARGE SPILL: DO NOT CLEAN-UP OR DISPOSE OF, EXCEPT UNDER SUPERVISION OF A SPECIALIST. (ERG, 2016)

Self-contained breathing apparatus; complete protective clothing; safety glasses; face shield. (USCG, 1999)|Personal Protective Methods: Clothing: Avoid skin contact with Bromine Trifluoride. Wear protective gloves and clothing. Safety equipment suppliers/manufacturers can provide recommendations on the most protective glove/clothing material for your operation. All protective clothing (suits, gloves, footwear, headgear) should be clean, available each day and put on before work. Eye Protection: Wear splash-proof chemical goggles and face shield when working with liquid, unless full facepiece respiratory protection is worn.|Wear special protective clothing and positive pressure self-contained breathing apparatus.

Not combustible, but if involved in a fire decomp to produce hydrogen fluoride and hydrogen bromide.

If material involved in fire: Do not use water on material itself. Use dry chemical or carbon dioxide. Cool all affected containers with flooding quantities of water. If large quantities of combustibles are involved, use water in flooding quantities as spray and fog. Use water spray to knock-down vapors.|Evacuation: If fire becomes uncontrollable or container is exposed to direct flame-consider evacuation of one-third (1/3) mile radius. If material leaking (not on fire) consider evacuation form downwind area based on amount of material spilled, location and weather conditions.|... Use appropriate extinguishing agents on nearby combustible fires. Use dry chemical, dry sand, or carbon dioxide ...|Bromine Trifluoide does not burn but may ignite combustible materials. Do not use water or foam. Use dry chemical or CO2 extinguishers. Poisonous gases are produced in fire including hydrogen fluoride and hydrogen bromide. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fire officials and pollution control agencies. Containers may explode in fire. From a secure, explosion-proof location, use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors, or shows any signs of deforming), withdraw immediately to a secure position. If employees are expected to fight fires, they must be trained and equipped in OSHA 1910.156.

Evacuate and restrict persons not wearing protective equipment from area of spill or leak until cleanup is complete. Remove all ignition sources. Collect powdered material in the most convenient and safe manner and deposit in sealed containers. Ventilate area of spill or leak after clean-up is complete. It may be necessary to contain and dispose of this chemical as a hazardous waste. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Contact your Department of Environmental Protection or your regional office of the federal EPA for specific recommendations. If employees are required to clean-up spills, they must be properly trained and equipped. OSHA 1910.120(q) may be applicable. ... Distances shown are likely to be affected during the first 30 minutes after materials are spilled and could increase with time. If more than one tank car, cargo tank, portable tank, or large cylinder is involved in the incident is leaking, the protective action distance may need to be increased.|Isolate the area until the release is under full control. Use water spray to cool and disperse vapors and protect personnel.

If material not involved in fire: Do not use water itself. Keep material out of water sources and sewers. Use water spray to knock-down vapors. Neutralize spilled material with crushed limestone, soda ash, or lime.|Personnel protection: Avoid breathing vapors. Keep upwind. ... Avoid bodily contact with the material. ... Do not handle broken packages unless wearing appropriated personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water.|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.
