I. PHYSICAL AND CHEMICAL CHARACTERISTICS

A. Made from three atoms of OXYGEN, Chemical symbol, O3.
B. Colorless in gaseous form, appears blue in "Thick Layers" {Blue Sky}.
C. Dark blue or almost black in liquid form.
D. Solid crystalline form is violet to blue in color.
E. Melting point ~ 80 K.
F. Boiling point ~ 161 K.
G. Has a very unique "Electric" odor that can be detected as low as 0.012 PPM.
H. Highly unstable and not possible to store, all users generate it on-site, as needed.


II. FORMATION

    A. Natural
  • 1.Lightning.
  • 2. Solar radiation. {Ultraviolet wavelengths A, B, & C}
  • 3. Photochemical Smog in large cities.
    B. Man-made
  • 1. Corona discharge. {Usually in air or oxygen atmospheres}
  • 2. High voltage gas discharge tubes. {Germicidal UV lamps}


III. SOLUBILITY
  • A. Soluble in water
  • 1. Affected by temperature, pressure and contaminant levels.

IV. OPTICAL PROPERTIES
  • A. Ozone has a peak absorption in the UV Spectrum at 255.3 NM, which puts its most effective band in the UV "C" spectrum. Without this particular property, no life could exist on the earth's surface.
V. EFFECTS ON HUMAN BEINGS
  • A. In low concentrations, {Less than 0.05 Parts Per Million}, OZONE has a sweet pleasant odor. It is responsible for the familiar odor of a thunder storm due to the OZONE created by lightning. {High voltage electrical discharge}
  • B. Natural ground-level concentrations are typically 0.03 PPM.
  • C. O.S.H.A. 24 hour exposure limit, 0.05 PPM, {Parts Per Million}
  • D. O.S.H.A. 8 hour exposure limit, 0.1 PPM
  • E. O.S.H.A. Short-term exposure limit, 0.3 PPM
  • F. Effective as a disinfectant and sterilizing agent at levels of 35% to 50% of that specified by O.S.H.A. for 24 hour exposure levels.
  • G. Prolonged exposure to high levels, {greater than 100 PPM}, produces headache and perhaps nausea.
  • H. Emergency first aid procedure is to remove victim from areas of high concentration, whereupon the symptoms will disappear.
VI. CONCENTRATION CONVERSION TABLE
    A. PHYSICAL PROPERTIES

    Standard conditions P = 1013.25 MB, T = 273.3 K

  • 1. Density of OZONE , 2.14 Kg / m3
  • 2. Density of oxygen, 1.43 Kg / m3
  • 3. Density of air, 1.29 Kg / m3
  • 4. Density of water, 1000 Kg / m3
B. USEFUL CONVERSION FACTORS
  • 1. 1000 liters = 1 m3 = 264 US gallons
  • 2. 1 g / m3 = 1 mg / L
C. OZONE CONCENTRATION IN WATER.

1. 1 g O3 / m3 H2O = 1 PPM O3 in water {By weight}

D. OZONE CONCENTRATION IN AIR BY VOLUME.

1. 1 g O3 / m3 AIR = 467 PPM O3 in air {By volume}

2. 1 PPM O3 in AIR by volume = 2.14 mg O3 / m3 AIR

E. OZONE CONCENTRATION IN AIR BY WEIGHT.

1. 100 g O3 / m3 AIR = 7.8% O3 in AIR {By weight}

2. 1% O3 in AIR by weight = 12.8 g O3 / m3 AIR

F. OZONE CONCENTRATION IN OXYGEN BY WEIGHT.

1. 100 g O3 / m3 O2 = 6.99% O3 in OXYGEN {By weight}

2. 1% O3 in OXYGEN {By weight} = 14.3 g O3 / m3 O2
