규제 정보Chemical: Calcium fluoride (CaF2)Directive (EC) No 46/2002Calcium fluoride (CaF2) is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Calcium fluoride (CaF2) are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)Status: Active Update: 26-04-2023 https://echa.europa.eu/registration-dossier/-/registered-dossier/15129Calcium fluoride: Does not have an individual approval but may be used under an appropriate group standard

화재 위험Not combustible.
건강 유해성Little acute toxicity (USCG, 1999)
유해성 요약Little acute toxicity[CAMEO] Normally stable, but decomposes into hydrogen fluoride when heated to 1200 deg C or mixed with concentrated acids[CHEMINFO] See FLUORIDES.
반응성 그룹Non-Redox-Active Inorganic Compounds
Reactivity ProfileCALCIUM FLUORIDE has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.
Chemical DangersOn combustion, forms toxic fumes of fluoride. Reacts with mineral acids. This produces corrosive fumes.
Air and Water Reactions
No rapid reaction with air. No rapid reaction with water.
Hazard Classes and CategoriesSkin Irrit. 2 (48.2%)
소화In case of fire in the surroundings, use appropriate extinguishing media.
응급 조치Fresh air, rest.Rinse and then wash skin with water and soap.First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.Rinse mouth.
응급 처치Usually no treatment needed (USCG, 1999)
안전 보관Separated from mineral acids.

보관 조건IN GENERAL, MATERIALS WHICH ARE TOXIC AS STORED OR WHICH CAN DECOMPOSE INTO TOXIC COMPONENTS ... SHOULD BE STORED IN COOL WELL VENTILATED PLACE, OUT OF DIRECT RAYS OF SUN, AWAY FROM ... HIGH FIRE HAZARD, & PERIODICALLY INSPECTED. INCOMPATIBLE MATERIALS SHOULD BE ISOLATED ...
처리 방법SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
누출 처리Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.
Preventive MeasuresIN THE MINING OF FLUORSPAR, DUST CONTROL SHOULD BE ... ENFORCED, INCLUDING WET DRILLING, WATERING OF LOOSE ROCK, AND EXHAUST & GENERAL VENTILATION. WHEN HEATING FLUORSPAR, THERE IS ALSO THE HAZARD OF HYDROFLUORIC ACID BEING FORMED, AND THE RELEVANT SAFETY MEASURES SHOULD BE APPLIED.SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.
Eye PreventionWear safety spectacles.
Inhalation RiskEvaporation at 20 °C is negligiblea harmful concentration of airborne particles can, however, be reached quickly on spraying.
Skin PreventionProtective gloves.
노출 경로The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.
Signs and SymptomsNausea. Vomiting.

Human Toxicity Excerpts... HAZARDS OF FLUORSPAR ARE DUE PRIMARILY TO ... FLUORINE CONTENT AND ITS SILICA CONTENT. CHRONIC INHALATION OR INGESTION MAY CAUSE LOSS OF WEIGHT AND APPETITE, ANEMIA, AND BONE AND TEETH DEFECTS. PULMONARY LESIONS ... REPORTED AMONG PERSONS INHALING DUST CONTAINING 92-96% CALCIUM FLUORIDE & 3.5% SILICA. ... CASES OF BRONCHITIS & SILICOSIS ...

ALTHOUGH LESS TOXIC IN ANIMALS, BARIUM FLUORIDE MAY BE AS TOXIC IN MAN AS THE SODIUM SALT (OR PREHAPS SLIGHTLY MORE TOXIC). CALCIUM FLUORIDE IS COMPARATIVELY BENIGN ... BECAUSE OF ITS LOW SOLUBILITY & LOW IONIZATION.
Non-Human Toxicity ExcerptsTOXICITY OF INORG FLUORINE COMPD VARIES &, TO EXTENT, DEPENDS UPON THEIR SOLUBILITY IN WATER ABOVE CERTAIN MIN LEVELS OF INTAKE. SODIUM FLUORIDE & SODIUM FLUOSILICATE (SILICOFLUORIDE) ARE MOST TOXIC & CALCIUM FLUORIDE (FLUORSPAR) IS LEAST TOXIC ...EMBRYOTOXIC STUDIES OF CALCIUM FLUORIDE IN MICE OVER SEVERAL GENERATIONS INDICATED THAT ADMIN DURING PREGNANCY WAS RELATIVELY SAFE COMPARED TO OTHER FLUORIDES. ACUTE (IP) & CHRONIC (ORAL) LD50 VALUES ARE GIVEN.The pathogenicity of mixed dust from a fluorite mine was studied by animal experiments and in vitro tests. Animal experiments showed that calcium fluorite can induce only a foreign body reaction in the lungsthe fibrous nodular lesions induced by the fluorite mine dust are due mainly to its silica component. It was demonstrated that either silica or the mixed dust of a fluorite mine can stimulate pulmonary alveolar macrophages to release fibrogenetic factors in vitro, but calcium fluorite cannot. It was also demonstrated that having engulfed calcium fluorite, silica, or fluorite mine mixed dust, pulmonary alveolar macrophages release an elastase-active substance. It was suggested that the emphysematous lesion seen in autopsy material of pneumoconiosis of fluorite mine workers may be caused by calcium fluorite and silica.
