SECTION 4: First-aid measures
4.1 Description of necessary first-aid measures
If inhaled
Fresh air, rest. Half-upright position. Refer for medical attention.
Following skin contact
First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention .
Following eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Following ingestion
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.
4.2 Most important symptoms/effects, acute and delayed
Inhalation causes extreme irritation of respiratory tract; pulmonary edema may result. Vapors are very irritating to eyes and skin; liquid causes severe burns. (USCG, 1999)
4.3 Indication of immediate medical attention and special treatment needed, if necessary
Fluoride is protoplasmic poison that binds with calcium, inhibits enzyme systems, and activates glycolic and proteolytic mechanisms. Management consists of symptomatic and supportive care, plus the administration of calcium and the treatment of hyperkalemia. Hemodialysis may be useful in severe cases. Prognosis is largely dictated by the clinical course over the first several hours. Survival beyond 4 hours is generally associated with a favorable outcome. Fluoride

SECTION 9: Physical and chemical properties and safety characteristics
| Physical state | Chlorine trifluoride is a colorless gas or green liquid with a pungent odor. Boils at 53°F. It reacts with water to form chlorine and hydrofluoric acid with release of heat. Contact with organic materials may result in spontaneous ignition. It is corrosive to metals and tissue. Prolonged exposure to low concentrations or short term exposure to high concentrations may result in adverse health effects. Under prolonged exposure to fire or intense heat the container may violently rupture and rocket. |

SECTION 10: Stability and reactivity
10.1 Reactivity
Decomposes above 220°C . This produces toxic gases of chlorine and fluorine compounds. Reacts violently with water and glass. Reacts with all forms of plastics, rubber and resins, except the highly fluorinated polymers. Most combustible materials ignite spontaneously on contact with this substance. Reacts violently with oxidizable materials, metals and metal oxides. Contact with organic materials causes explosion. Contact with acids causes emission of highly toxic fumes.
10.2 Chemical stability
Unstable/ in moist air...
10.3 Possibility of hazardous reactions
Spontaneously combusts on contact with organic or silicacious matter.The gas is heavier than air.CHLORINE TRIFLUORIDE is a low-boiling liquid (b.p. 12° C) which is irritating and toxic in the gaseous state. A highly reactive oxidant, it is spontaneously flammable and used as a rocket propellant. It is incompatible with fuels and nitro compounds. Interaction with water is violent and may be explosive, even with ice [Sidgwick, 1950, p. 1156]. It undergoes an immediate explosive reaction on contact with hydrocarbons or halocarbons even at -70° C [Brower, K. R., J. Fluorine Chem., 1986, 31, p. 333]. Solutions with carbon tetrachloride are capable of detonation, while solutions with nitroaryl compounds (TNT, hexanitrobiphenyl) or highly chlorinated compounds are extremely shock-sensitive. Violent, sometimes explosive reaction with hydrogen containing materials, e.g., acetic acid, ammonia, benzene, ether, coal gas, hydrogen, hydrogen sulfide, methane, or fluoroamino compounds. Ignition with fibrous materials (cotton, paper, wood). [Mellor, 1956, vol. 2, suppl. 1, p. 155]. Explosive gaseous products (chlorodifluoroamine) are formed with ammonium fluoride or ammonium hydrogen fluoride [Gardner, D. M. et al., Inorg., Chem., 1963, 2, p. 413]. Ignition occurs on contact with iodine, boron-containing materials (boron powder, tetraboron carbide, boron-aluminum), fibrous or finely divided refractory materials (asbestos, glass, wool, sand, tungsten carbide). Violent reactions occur with mineral acids (nitric acid, sulfuric acid), chromium trioxide, ruthenium metal, selenium tetrafluoride. [Bretherick, 5th ed., 1995, p. 1235]. Chlorine trifluoride is a hypergolic oxidizer and contact with a number of metals and their oxides (aluminum, antimony, arsenic, calcium, copper, iridium, iron, lithium, lead, magnesium, molybdenum, osmium, potassium, rhodium, sodium, selenium, silver, tellurium, tin, tungsten, zinc), nonmetals (phosphorus, silicon, sulfur), salts (mercury iodide, potassium iodide, silver, nitrate, potassium carbonate) will result in a violent reaction often followed by ignition [Mellor, 1956, vol. 2, suppl. 1, p. 155; Sidgwick, 1950, p. 1156].

10.6 Hazardous decomposition products
In the vapor phase, chlorine trifluoride decomposes into a variety of substances, Cl2, ClF, ClOF, CLO2F, ClO2, & HF, depending upon the availability of water; of these chlorine, hydrogen fluoride & chlorine dioxide are probably of greatest toxicologic significance.

Other Information
Thorough flushing with an inert gas should precede any opening of apparatus that has contained chlorine trifluoride.Reacts violently with fire extinguishing agents such as water.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 a person authorized by him/her, should be considered.Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.Do NOT spray water on leaking cylinder (to prevent corrosion of cylinder).See ICSC 0283.
