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’s 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, reduced
visual acuity, and pulmonary edema. Symptoms of edema from excessive exposure can be delayed one or more hours.
Inhalation of >20 ppm for an hour or more (>50 ppm for 1/2 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 - Gently lift eyelids and flush eyes continuously with flooding amounts of water for 15 minutes or until transported to a
medical facility*.
Inhalation - Remove exposed person to fresh air, support breathing, administer humidified oxygen as needed, get medical help*.
Ingestion - Highly unlikely since ozone is a gas until -169 ° F,
*
GET MEDICAL 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 to 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) - Self Contained Breathing Apparatus: MISH/NIOSH approved.
Low Level (0.3 - 10 ppm) - Canister Type (carbon) respirator may be used.
Eye Protection:
Wear chemical safety goggles if necessary to work in high ozone (>10 ppm).
Skin Protection:
Effects of ozone on skin are minimal to non-existent.
Ventilation:
Provide general and local exhaust ventilation to dilute & disperse small amounts of ozone into 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 sect. II). Install ambient ozone monitor(s) configured to shut down ozone equipment and turn high speed
ventilation on.
