Ozone Material Safety Data Sheet
Section I: MATERIAL IDENTIFICATION
IDENTITY: OZONE (Gaseous) ISSUED: February, 1992
FORMULA: O蟹 REVISED: September, 2001
Description (origin/uses): Occurs in atmosphere from UV light action on oxygen at high
altitude. Commercially obtained by passing air between electrodes carrying a high voltage alternating
current. Also found as a by-product in welding areas, high voltage equipment, or UV radiation.
Ozone is used as an oxidizing agent in air and water disinfection, for bleaching textiles, oils, and waxes,
organic synthesis as an processing certain perfumes, vanillin, campher, for mold and bacteria control in
cold storage.
Cautions: A powerful oxidizing agent, ozone generally exists as a gas and is highly chemically reactive.
Inhalation produces various degrees of respiratory effects from irritation to pulmonary edema (fluid in
lungs) as well as affecting the eyes, blood, and central nervous system.
Manufacturer/Supplier: On-site generation, equipment available from various suppliers including:

Appearance and Odor: Colorless to blue gas (greater than -169掳F): characteristic odor often
associated with electrical sparks or lightning in concentrations or less than 2 ppm and becomes
disagreeable above 1-2 ppm. CAUTION: Olfactory fatigue develops rapidly, so do not use odor as a
preventative warning device.
SECTION IV: FIRE AND EXPLOSION HAZARD DATA
Flash Point鈥︹?︹??...鈥?..Nonflammable
Extinguishing Media:...Use large amounts of water spray or fog to put out fires involving ozone. Use
appropriate fire-fighting techniques to deal with surrounding material.
Special Fire Fighting Procedures: Wear a self contained breathing apparatus with full
facepieces operated in a pressure-demand or other positive-pressure mode.
Unusual Fire/Explosion Hazards: Decomposition of ozone into oxygen gas. (O虏), can increase
strength of fire.
SECTION V: REACTIVITY DATA
Stability: Ozone is not stable. Hazardous polyrnerization cannot occur.
Chemical Incompatibilities: Ozone is chemically incompatible with all oxidizable materials, both
organic and inorganic.
Conditions to Avoid: Ozone is unstable at room temperature and spontaneously decomposes to
oxygen gas. Avoid ignition sources such as heat, sparks, and open flame. Keep away from strong reducing
agents and combustible materials such as grease, oils, and fats.
Products of Hazardous Decomposition: Ozone spontaneously decomposes to oxygen gas, even
at room temperatures.
SECTION VI: HEALTH HAZARD DATA
Carcinogenicity: Ozone is not listed as a carcinogen by the NTP, IARC, or OSHA.
Primary Entry: Inhalation
Target Organs: Respiratory system, eyes, blood.
Summary of Risks: There is no true threshold limit and so no exposure (regardless of how small) is
theoretically without effect from ozone鈥檚 strong oxidative ability. Ozone passes straight to the smallest
bronchioles and alveoli and is not absorbed by mucous membranes along the way. Initial small exposure
may reduce cell sensitivity and/or increase mucous thickness producing a resistance to low ozone levels.
Short exposure to 1-2 ppm concentrations causes headache as well as irritation to the respiratory tract, but
symptoms subside when exposure ends. High concentrations of ozone produce severe irritation of the eyes
and respiratory tract. Exposure above the ACGIH/OSHA limits produce nausea, chest pain, coughing,
fatigue, reduces visual acuity, and pulmonary edema. Symptons of edema from excessive exposure can be
delayed one or more hours, inhalation of >20 ppm for an hour or more (>50 ppm for 陆 hour) can be fatal.
Acute Effects: Acute damage from ozone appears to be mainly from its oxidizing effect on contact with tissue.
Chronic effects: Respiratory disease. Deleterious effects on lungs and acceleration of tumors have been reported.
Medical Conditions Generally Aggravated by Long-term Exposure: History of respiratory
or heart disorders.
First Aid: Remove from ozone containing air, get prompt medical help*, administer oxygen if
necessary.
Eye contact 鈥? Gently lift eyelids and flush eyes continuously with flooding amounts of water for 15
minutes or until transported to a medical facility*.
Inhalation 鈥? Remove exposed person to fresh air, support breathing, administer humidified oxygen as
needed, get medical help*.
Ingestion 鈥? Highly unlikely since ozone is a gas until -169掳F.
*GET MEDIAL ASSISTANCE, APPROPRIATE IN-PLANT, PARAMEDIC, OR
COMMUNITY.Get prompt medical assistance for further treatment, observation, and support after
first aid.
SECTION VII: PRECAUTIONS FOR SAFE HANDLING AND USE
Steps to be taken in Case of Spill/Leak:
1. Discontinue production
2. Isolate and vent area
3. Immediately notify personnel
4. Deny entry
5. Follow applicable OSHA regulations.
Disposal: Provide ventilation in dilute and disperse small amounts of ozone (below OSHA PELs) to
outside atmosphere. Follow federal, state, and local regulations.
Handling/Storage Precautions: Ensure proper personnel training and establish emergency
procedures.
SECTION VIII: CONTROL MEASURES
Respiratory Protection: High level (>10 ppm) 鈥? Self Contained Breathing Apparatus: MISH/NIOSH
approved. Low level (0.2 鈥?10 ppm) 鈥? Canister Type (carbon) respirator may be used.
Eye Protection: Wear chemical safety goggles if necessary to work in high ozone (> 10 ppm)
Skin Gloves: Effects of ozone on skin are minimal to non-existent.
Ventilation: Provide general and local exhaust ventilation to dilute and disperse small amounts of ozone
into the outside atmosphere.
SECTION IX: SPECIAL PRECAUTIONS AND COMMENTS
Storage Segregation: Prevent ozone from coming into direct physical contact with strong acids or
bases or with strong oxidizing/reducing agents.
Engineering Controls: Install ventilation systems capable of maintaining ozone to concentrations
below the ACGIH/OSHA exposure limits (see section II) install ambient ozone monitor(s) configured to
shut down ozone equipment and turn high-speed ventilation on.
