Physical Description | Chlorine trifluoride appears as 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.

Toxicity

Probable Routes of Human Exposure

The hazard of exposure to chlorine trifluoride in atmosphere is at least as great as that of chlorine.

Symptoms

Eye, skin burns (liquid or high vapor concentration); resp irritation; In Animals: lacrimation (discharge of tears), corneal ulcer; pulmonary edema

Target Organs

Skin, eyes, respiratory system

Toxicity Data

LC50 (rat) = 299 ppm/1H

Adverse Effects

Toxic Pneumonitis - Inflammation of the lungs induced by inhalation of metal fumes or toxic gases and vapors.

Exposure Routes

inhalation, ingestion (liquid), skin and/or eye contact

Human Toxicity Excerpts

Liquid chlorine trifluoride causes deep penetrating burns on contact with body. The effect may be delayed & progressive, as in the case of burns by hydrogen fluoride.

Non-Human Toxicity Values

LC50 Mouse inhalation 178 ppm/1 hr

Non-Human Toxicity Excerpts

Chlorine trifluoride is an extremely reactive, corrosive and irritating gas which experimentally has been observed to cause a severe reaction in the lungs and in all exposed mucous membranes. It it highly irritating to the skin and eyes, and has caused severe corneal ulcers in dogs.

Populations at Special Risk

Persons with impaired pulmonary function may be at increased risk from exposure.

Antidote and Emergency Treatment

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/
