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.

Extinguishing
Media:

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.

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.

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.
