TIH (Toxic Inhalation Hazard) - Term used to describe gases and volatile liquids that are toxic when inhaled. Some are TIH materials themselves, e.g., chlorine, and some release TIH gases when spilled in water, e.g., chlorosilanes. [ERG 2016].

Fire Fighting Procedures · 4 Einträge

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.

Storage Conditions · 2 Einträge

Bromine Trifluoride must be stored to avoid contact with Water (which releases Hydrogen Fluoride gas), Ammonium Halides, Antimony Trioxide, Antimony Chloride and Solvents (such as Ether, Acetone, Acetic Acid and Toluene), since violent reactions occur. Store in tightly closed containers in a cool, well-ventilated area away from Organic and/or Combustible Materials (such as Wood, Cotton and Straw), Chloride and Bromide salts and many metals. Whenever Bromine Trifluoride is used, handled, manufactured, or stored, use explosion-proof electrical equipment and fittings. See OSHA standard 1910.104 and NFPA 43A Code for the Storage of Liquid and Solid Oxidizers for detailed handling and storage regulations

Separate from acids, alkalies, halogens, salts, metaloxides. Store in a cool, dry, well-ventilated location. Keep cylinders restrained ...

Cleanup Methods · 2 Einträge

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.

Disposal Methods · 2 Einträge

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.

Preventive Measures · 3 Einträge

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.

Health Effects · 1 Eintrag

Bromine vapour causes irritation and direct damage to the mucous membranes. Elemental bromine also burns the skin. The bromide ion is a central nervous system depressant and chronic exposure produces neuronal effects. This is called bromism and can result in central reactions reaching from somnolence to coma, cachexia, exicosis, loss of reflexes or pathologic reflexes, clonic seizures, tremor, ataxia, loss of neural sensitivity, paresis, papillar edema of the eyes, abnormal speech, cerebral edema, delirium, aggressiveness, and psychoses. (L625, L626, L627)

Adverse EffectsDermatotoxin - Skin burns.
Exposure RoutesOral (L626) ; inhalation (L626) ; dermal (L626)
Toxicity Summary · 1 Eintrag

Bromine is a powerful oxidizing agent and is able to release oxygen free radicals from the water in mucous membranes. These free radicals are also potent oxidizers and produce tissue damage. In additon, the formation of hydrobromic and bromic acids will result in secondary irritation. The bromide ion is also known to affect the central nervous system, causing bromism. This is believed to be a result of bromide ions substituting for chloride ions in the in actions of neurotransmitters and transport systems, thus affecting numerous synaptic processes. (L626, L627, A543)

Signs and Symptoms · 1 Eintrag

Bromine vapour causes irritation and direct damage to the mucous membranes. Symptoms include lacrimation, rhinorrhoea, eye irritation with mucous secretions from the oropharyngeal and upper airways, coughing, dyspnoea, choking, wheezing, epistaxis, and headache. The bromide ion is a central nervous system depressant producing ataxia, slurred speech, tremor, nausea, vomiting, lethargy, dizziness, visual disturbances, unsteadiness, headaches, impaired memory and concentration, disorientation and hallucinations. This is called bromism. (L626, L627)
