SECTION 3 – PHYSCIAL DATA

Coiling Point -169.42oF (-111.9oC) Melting Point -315.4oF (-193oC)

Vapor Pressure -1 ATM % Volatile by Volume 100

Water Solubility Negligible Molecular Weight 48 Grams/Mole

Density of Gas (Air=1) 1.6 pH Not Listed

Critical Temperature 10.22oF (-12.1oC)

Appearance and odor Blue-colored gas or liquid; characteristic odor often associated with electrical sparks or lightning in concentrations of less than 2 ppm.

COMMENTS: The pungent characteristic odor of ozone is detectable above 0.01 ppm and becomes disagreeable (sulfur like) above 1 to 2 ppm.

CAUTION: Olfactory fatigue develops rapidly so do not use door as preventative warning device.

 

SECTION 4 – FIRE AND EXPLOSION DATA LOWER UPPER

Flash Point and Method Auto-ignition Temperature Flammability Limits in Air

EXTINGUISHING MEDIA: Use large amounts of water spray or fog to put out fires involving ozone. The material increases the intensity of combustion as compared to the burning or exploding of material in air or with a comparable amount of oxygen gas, O2 (g). Use appropriate fire-fighting techniques to deal with the surrounding material.

UNUSUAL FIRE/EXPLOSION HAZARDS: CAUTION: Ozone is a powerful oxidizing agent, and during fires or heated condition solutions containing ozone explode when warmed.

SPECIAL FIRE-FIGHTING PROCEDURES: Wear self-contained breathing apparatus with full-face pieces operated in a pressure demand or other positive pressure mode.

 

SECTION 5 – REACTIVITY DATA

Ozone is not stable. Hazardous polymerization cannot occur

CHEMICAL INCOMPATABILITIES: Ozone is chemically incompatible with all oxidizable materials but organic and inorganic.

CONDITION TO AVOID: Avoid ignition sources such as heat, sparks or open flames. Ozone is unstable at ordinary temperatures because it spontaneously decomposes to oxygen gas. Keep it away from heat, strong reducing agents, and combustible materials such as grease, oils and fats.

PRODUCTS OF HAZARDOUS DECOMPOSITION: Ozone spontaneously decomposes to oxygen even at ordinary room temperatures.

 

SECTION 6 – HEALTH HAZARD INFORMATION

Ozone is not listed as a carcinogen.

SUMMARY OF RISK: High concentrations of ozone may cause severe irritation of the eyes and respiratory tract. Exposure above 0.1 ppm causes the mucous membrane of the mouth, nose and throat to dry. A short exposure to 1 to 2 ppm causes headaches as well as irritation to the respiratory tract, but these symptoms subside when the exposure ends. High concentrations and/or repeated or prolonged exposure above the ACGIH/OSHA exposure limits produce nausea, chest pain, coughing, fatigue reduced visual acuity and pulmonary edema may be significantly delayed (one or more hours) from the time of initial exposure. Toxic effects reported include eye, skin, and CNS effects.

TARGET ORGANS: Respiratory systems, eyes. PRIMARY ENTRY: Inhalation ACUTE EFFECTS: The acute damage from ozone appears to be the result of its oxidation effect upon contact with tissue. The acute effects of ozone inhalation include eye irritation, mucous membrane irritation and pulmonary edema.

CHRONIC EFFECTS: Respiratory diseases. Deleterious (ozone inhalation) effects on the lungs and acceleration of tumors have been reported as chronic effects on exposure to ozone.

FIRST AID; EYE CONTACT Flush eyes, including under eyelids, promptly and gently with plenty of running water for 15 minutes. Get medical help.

SKIN CONTACT: Skin contact with cryogenic liquid ozone will cause severe frostbite or breeze burns to dermal layers. Prolonged or repeated skin contact will increase the severity or depth of these burns. Get medical help.*

INHALATION: As a gas or cryogenic liquid, ozone is unlikely to be ingested.

*GET MEDICAL ASSISTANCE-IN PLANT PARAMEDIC, COMMUNITY. Get prompt medical assistance for further treatment, observation, and support after first aid.

 

SECTION 7 – SPILL, LEAK AND DISPOSAL PROCEDURES

SPILL/LEAK: Before using ozone, it is essential that proper emergency procedures be established and made known to all personnel involved in handling it. Use approved NIOHS respirators in emergency /IDLH condition. Ozone leaks may be detected by exposing paper impregnated with dried 4% potassium iodide to the suspected leak. If the paper turns brown, it is an indication that ozone is present.

DISPOSAL: Provide ventilation to dilute and dispense small amounts of ozone into the outside atmosphere. Follow Federal, State and Local regulations.

Ozone is not designated as a hazardous substance by the EPA (40 CFR 116)

Ozone is reported in 1980 EPA TSCA Inventory.

EPA Hazardous Waste Number (40- CFR 261): Not listed

EPA Reportable Quantity: Not listed, Aquatic Toxicity Tim: Not listed

Ozone is an OSHO Air Contaminate (29 CFR 1910.1000, Subpart Z: Table Z-1)

 

SECTION 8 – SPECIAL PROTECTION INFORMATION

GOGGLES: Wear protective eyeglasses or chemical safety goggles.

GLOVES: Wear Impervious gloves made of neoprene or rubber with fully protective gauntlets to protect against frostbite or freezerburns from cryogenic liquid ozone.

RESPIRATOR: For IDLH/ unknown concentration, use a self-contained breathing apparatus with a full-face piece operated in a pressure-demand or other positive-pressure modes.

OTHER EQUIPMENT: Wear rubber boots, protective aprons and other protective clothing to prevent any possible skin contact with liquid ozone that would result in frostbite/freezer burns.

VENTILATION: Provide general and local exhaust ventilation to meet ACGIH exposure values. Provide ventilation to dilute and disperse small amounts of zone into the outside atmosphere. Ozone is highly toxic and properly maintained engineering ventilation systems are crucial to a safe work environment.

SAFETY STATIONS: Make an eye wash station, washing facilities and safety showers available in areas of use and handling.

SPECIAL CONSIDERATION: See Calabrese et al J. Toxic Heath (1977) 2:709

 

SECTION 9 – SPECIAL PRECUATIONS AND COMMENTS

STORAGE SEGREGATION: Prevent ozone from coming into direct physical contact with strong acids or bases with strong oxidizing/reducing agents.

SPECIAL HANDLING/STORAGE: Ozone can be stored for a prolonged period as a liquid under cryogenic conditions.

CAUTION: Solutions containing ozone can explode when warmed. Also, some products of reactions such as ozonides formed from unsaturated hydrocarbons may be highly explosive.

ENGINEERING CONTROLS: Install ventilation systems that are able to maintain ozone use concentration below the ACGIH/OSHA exposure limit. Minimize or eliminate all sources of ignition such as open flame or sparks.

OTHER PRECAUTIONS: Where ozone is generated (or where liquid ozone is stored or used), explosion hazards exist and must be avoided by proper planning, equipment engineering systems, training, and work practices.
