• In the event of ozone leak a Ventilate the area.
• Immediately switch the ozone generator off.
• Where high levels of ozone are experienced (in excess of 0.1 ppm), all personnel should vacate the affected area until it has been thoroughly ventilated.
• Where ozone levels in excess of 0.3 ppm are present, or when personnel are required to work in restricted spaces or tanks, where ozone may be present, only persons wearing suitable breathing apparatus should be allowed in the area and the appropriate safe working practices for confined areas should be applied.
Disposal of waste ozone gas :-
It is accepted practice, and required by statute in some jurisdictions, that Ozone gas should not be released into the atmosphere but should be destroyed using an approved ozone destruction method.
Plant Engineering Considerations :-
• All potential outlets for ozone gas into the occupied areas or external atmosphere should be identified. All routine operational releases of ozone to the occupied areas or the external atmosphere should be contained and passed through an ozone destruction system.
• All occupied areas where ozone is generated or applied should be provide with an effective ventilation system commensurate with the rate of ozone production and other risk factors. Suitable masks or breathing apparatus should be readily available for the protection of personnel in the event of leakage and for protection where working requirements make it impossible to avoid contact with ozone.
First Aid Measures :-
• Eye Exposure - If ozone gets into the eyes, wash eyes immediately with large amounts of water, lifting the upper and lower eye lids occasionally. Seek medical attention as soon as possible.
• Breathing - If a person breathes in large amounts of ozone, move the person into warm-contaminated air at once. If breathing has stopped, perform artificial respiration. When breathing is difficult, properly trained personnel may assist by administering breathing oxygen. Keep the affected person warm and at rest. Seek medical attention as soon as possible.
• Rescue - Move the affected person to safety. If the person has been overcome notify somebody else and put into effect the established emergency procedures. Do not enter the affected area without assistance or against the advice of the recommended safety procedures as they may apply at each facility.
