3. Hazards Identification
Emergency Overview
---------------------------------
Highly reactive, can explode on contact with organic substances,
especially strong reducing agents.
Ozone is a powerful oxidizing agent and oxidation with ozone evolves more heat and usually
starts at a lower temperature than oxidation with oxygen. It reacts with non-saturated organic
compounds to produce ozonides, which are unstable and may decompose with explosive
violence. Ozone is an unstable gas which, at normal temperatures, decomposes to diatomic
oxygen. At elevated temperatures and in the presence of certain catalysts such as hydrogen,
iron, copper and chromium, this decomposition may be explosive.
Potential Health Effects
----------------------------------
Inhalation: Causes dryness of the mouth, coughing, and irritates the nose, throat, and chest.
May cause difficulty in breathing, headache, and fatigue. The characteristic sharp, irritating odor
is readily detectable at low concentrations (0.01 to 0.05 ppm).
Skin: Absorption through intact skin is not expected.
Eye Contact: Ozone is an irritant to the eyes causing pain, lacrimation, and general
inflammation.
Ingestion: Not a route of exposure.
Aggravation of Pre-existing Conditions:
Ozone may increase sensitivity to bronchoconstrictors including allergens.
4. First Aid Measures
Inhalation:
Remove to fresh air; if breathing is difficult a trained person should administer oxygen. If
respiration stops, give mouth-to-mouth resuscitation. Get medical attention.
Ingestion:
Not an expected route of exposure.
Skin Contact:
Wash skin thoroughly with soap and water.
Eye Contact:
Immediately flush eyes with large amounts of water for at least 15 minutes, while forcibly
holding eyelids apart to ensure flushing of the entire eye surface. If irritation, pain, or
other symptoms persist seek medical attention.
Acute:
May cause irritation of skin, eyes, and mucous membranes of the respiratory tract.
Drowsiness, dizziness, headache, and fatigue have been associated with exposure.
Chronic:
Long term health effects are not expected from exposures to ozone. A partial tolerance
appears to develop with repeated exposures.
5. Fire Fighting Measures
Flash Point:
N/D
Auto ignition Temperature:
N/D
Flammable Limits in air, % by volume - Upper: N/D Lower: N/D
Extinguishing Media:
Use extinguishing media suitable for surrounding fires.
Unusual Fire and Explosion Hazard: None expected. Since ozone is highly unstable
and decomposes under all conditions and is not encountered except at very small levels
in the immediate vicinity where formed.
6. Accidental Release Measures
Evacuate danger area. Open doors and windows to allow area to
ventilate. Consult an expert.
Ozone should be contained within a chemically compatible piping system.
Ozone is a powerful oxidizing agent and oxidation with ozone evolves
more heat and usually starts at a lower temperature than oxidation with
oxygen. It reacts with non-saturated organic compounds to produce
ozonides, which are unstable and may decompose with explosive
violence. Ozone is an unstable gas which, at normal temperatures,
decomposes to diatomic oxygen.
8. Exposure Controls/Personal Protection
Exposure Guidelines:
OSHA PEL: 0.10-ppm PEL/TLV
Ventilation Requirements:
General exhaust recommended. Avoid working with ozone generating
equipment in enclosed spaces.
Specific Personal Protective Equipment
Respiratory:
Respirators may be used when engineering and work practice controls are not technically
feasible, when such controls are in the process of being installed, or when they fail and need to
be supplemented. Respirators may also be used for operations which require entry into tanks or
closed vessels, and in emergency situations.
Only appropriate respirators shall be provided and used when the use of respirators is the only
means of controlling exposure for routine operations, or during an emergency. (Refer to Table 1
of ANSUI/ASTM E591-77 for appropriate respirator selection ).
Positive pressure air line with mask or self-contained breathing apparatus should be available for
emergency use.
Eye:
Not necessary
Gloves:
Not necessary.
Other Clothing and Equipment:
Not necessary.

Appearance and Odor:
Colorless to bluish gas with a characteristic pungent odor similar to the smell after strong lightning
storms.
10. Stability and Reactivity
Stability:
Ozone spontaneously decomposes under all ordinary conditions, so that it
is not encountered except in the immediate vicinity of where it was formed.
The decomposition is speeded by solid surfaces and by many chemical
substances.
Hazardous Decomposition Products:
Free radical oxygen. O-)
Hazardous Polymerization:
Will not occur.
Incompatibilities:
Ozone is a powerful oxidizing agent and reacts with all oxidizable
materials , both organic and inorganic. Some reactions are highly
explosive. Alkenes, benzene and other aromatic compounds, rubber,
dicyanogen, bromine diethyl ether, dinitrogen tetroxide, nitrogent
trichloride, hydrogen bromide, and tetrafluorohydrazine.
11. Toxicological Information
Ozone is extremely irritating to the upper and lower respiratory tract. The
characteristic odor is readily detectable at low concentrations ( 0.02 ppm
to 0.05 ppm). Ozone produces local irritation of the eyes and mucous
membranes and may cause pulmonary edema at high exposure.
Systematically, ozone has been reported to mimic the effects of ionizing
radiation, and may cause damage to chromosomal structures. A partial
tolerance appears to develop with repeated exposures. Although most
effects are acute, the possibility of chronic lung impairment should be
considered, based upon animal experimentation.

Environmental Fate:
No information found.
Environmental Toxicity:

13. Disposal Considerations
Do not dispose of ozone off gas to atmosphere without properly designed off gas destruct unit. State and
local disposal regulations may differ from federal disposal regulations.
