Safety Statements: A human poison by inhalation. Human systemic effects by inhalation: visual field changes, lachrymation, headache, decreased pulse rate with fall in blood pressure, dermatitis, cough, dyspnea, respiratory stimulation and other pulmonary changes. Experimental teratogenic and reproductive effects. Human mutation data reported. A skin, eye, upper respiratory system, and mucous membrane irritant. Questionable carcinogen with experimental neoplastigenic and tumorigenic data. Can be a safe water disinfectant in low concentration. Concentration of 0.015 ppm of ozone in air produces a barely detectable odor. Concentrations of 1 ppm produce a disagreeable sulfur like odor and may cause headache and irritation of eyes and the upper respiratory tract; symptoms disappear after leaving the exposure.A powerful oxidizing agent. Dangerous chemical reaction with acetylene, alkenes, alkylmetals (e.g., dimethylzinc, diethylzinc), antimony, aromatic compounds (e.g., benzene, aniline), benzene + oxygen + rubber, bromine, charcoal + potassium iodide, citronellic acid, combustible gases (e.g., carbon monoxide, ethylene, nitrogen oxide, ammonia, phosphine), (diallyl methyl carbinol + acetic acid), trans-2,3-dichloro-2-butene, dicyanogen, dienes + oxygen, diethyl ether, 1,1-difluoroethylene, N2O5, ethylene + formyl fluoride, fluoroethylene, liquid hydrogen, hydrogen + oxygen difluoride, hydrogen bromide, hydrogen iodide, 4-hydroxy-4-methyl-1,6-heptadiene, 2,3-hydroxy-2,2,4-trimethyl-3-pentenoic acid lactone, isopropylidene compounds, nitrogen, NO2, NO, nitrogen trichloride, nitrogen triiodide, nitroglycerin, organic liquids, organic matter, oxygen + rubber powder, oxygen fluorides (e.g., dioxygen difluoride, dioxygen trifluoride), silica gel, stibine, tetrafluorohydrazine, tetramethylammonium hydroxide, trifluoroethylene, unsaturated acetals. A severe explosion hazard in liquid form when shocked, exposed to heat or flame, or in concentrated form by chemical reaction with powerful reducing agents. Incompatible with rubber; dinitrogen tetraoxide. See also OZONIDES and PEROXIDES, INORGANIC; PEROXIDES, ORGANIC.
Hazard Symbols: Dangerous fire and explosion risk in contact with organic materials. Toxic by inhalation, strong irritant. TLV: ceiling of 0.1 ppm; STEL 0.3 ppm. EPA standard for ambient air is 0.12 ppm.

Title: Ozone
CAS Registry Number: 10028-15-6
Synonyms: Triatomic oxygen
Molecular Formula: O3
Molecular Weight: 48.00
Percent Composition: O 100.00%
Literature References: Found in the atm in varying proportions (about 0.05 ppm at sea level), since it is produced continuously in the outer layers of the atm by the action of solar uv radiation on the oxygen of the air. So-called sterilizing lamps operate on the same principle. In the laboratory ozone is prepd by passing dry air between two plate electrodes connected to an alternating current source of several thousand volts. The reaction is reversible, and after a little ozone has been produced it is dec at the same rate as it is generated. Obtained in pure form by cooling ozonized air to -180° when it separates as a dark blue liquid. See also C. E. Thorp, Bibliography of Ozone Technology (Armour Res. Found., Chicago). Lab prepn: Org.

Properties: Bluish, explosive gas or blue liquid. Pleasant, characteristic odor in concns of less than 2 ppm. Irritating and injurious in higher concns. Powerful oxidizing agent. d0 (gas): 2.144 g/l; d-195.4 (liq) 1.614 g/ml. mp -193°. bp -111.9°. Critical temp -12.1°. Critical press. 53.8 atm. Heat of formation 34.4 kcal/mole at 25°. Intense absorption band beginning at about 290 nm. Unstable. Solutions contg ozone explode on warming. Prepn of ozone solns in liq oxygen: Cook, US 3008902 (1961 to Union Carbide). Although the stability of ozone in aq solns decreases as alkalinity rises, this effect is reversed at high concns. For example, the half life of ozone is 2 min in 1N NaOH; it is increased to 83 hrs in 20N NaOH: Heidt, Landi, J. Chem. Phys. 41, 176 (1964).

CAUTION: Potential symptoms of overexposure are irritation of eyes and mucous membranes; pulmonary edema; chronic respiratory disease. See NIOSH Pocket Guide to Chemical Hazards (DHHS/NIOSH 97-140, 1997) p 238.
Use: As disinfectant for air and water by virtue of its oxidizing power. For bleaching waxes, textiles, oils. In organic syntheses. Forms ozonides which are sometimes useful oxidizing compds.
