Physical Description | Oxygen difluoride appears as a colorless poisonous gas with a strong peculiar odor. Highly toxic by inhalation. Corrosive to skin and eyes. Can explode on contact with water. Decomposes to toxic gaseous fluorine if heated to high temperature. Prolonged exposure of the containers to high heat may result in their violent rupturing and rocketing. Used as an oxidizer for propellants.

Toxicity
ToxicityEffluent Concentrations
DISPOSAL OF WASTE FLUORIDE IN EFFLUENT FROM URANIUM OXIDE CONVERSION FACILITY. FLUORINE MONOXIDE WAS DETECTED IN EFFLUENT GASES.
Symptoms
irritation eyes, skin, respiratory system; headache; pulmonary edema; eye, skin burns (from contact with the gas under pressure)
Target Organs
Eyes, skin, respiratory system
Toxicity Data
LC50 (rat) = 2.6 ppm/1H
Adverse Effects
Toxic Pneumonitis - Inflammation of the lungs induced by inhalation of metal fumes or toxic gases and vapors.
Exposure Routes
inhalation, skin and/or eye contact
Non-Human Toxicity Values
LC50 Monkey inhalation 16 ppm/60 min
Non-Human Toxicity Excerpts
... LC50 values of 20 ppm were reported in monkeys and dogs exposed to oxygen difluoride. Signs of toxicity included lacrimation, dyspnea, muscular weakness, and vomiting. At autopsy, massive pulmonary edema and hemorrhage were observed.
Populations at Special Risk
Excess cancer rates have been documented in various occupational groups exposed to fluorides. Thus, fluorspar miners ... and aluminum production workers ... have been subject to lung cancer more frequently than expected. ... Because most occupational exposures that include fluoride are mixed exposures, only limited evidence from such studies bears specific relevance to the wider concept of the possible carcinogenic effects of long-term fluoride exposures on human beings. /Fluorides/
Antidote and Emergency Treatment
Treatment /of acute poisoning/ includes the iv admin of glucose in saline and gastric lavage with lime water (0.15% calcium hydroxide soln) or other Ca+2 salts to precipitate the fluoride. Calcium gluconate is given iv for tetany; urine volume is kept high with vigorous fluid resuscitation. /Fluoride/
