Ozone Gas

Ozone is generated by reaction of short-wave UV radiation on air and is a
gas which readily reverts to oxygen when mixed with atmospheric air as it is
removed from the source of UV radiation. Quantity of ozone produced
equates to 0.001 cu.ft/kWHr.
NOTE: Ozone should be ducted via a sealed duct to atmosphere and
discharged according to local regulations. (Height and clearance from
pedestrian walkways and opening windows, etc.).
Ozone checks using a Draeger measuring device should be carried out
every 6 months, or immediately, if an operator can smell ozone. Please
contact your local service department for availability and cost.
Outlet duct concentration is 0.3 PPM in a typical system. Threshold limit
value (TVL) is 0.1 PPM in a working atmosphere.
Precautions
Symptoms of ozone present in the working environment.
Ozone has an irritant action on the mouth and throat and the Factory
Inspectorate recommendation is that the level of ozone in the atmosphere of
a factory should not exceed 0.1 PPM (TLV). Most people can smell ozone
at about one third of the TLV. If there is any doubt as to whether the TLV is
being exceeded, the company should take measurements to check whether
the extraction system is adequate to keep the atmosphere well below 0.1
PPM.
If detected:
a. Shutdown system.
b. Check ducting for leaks.
c. Before starting check working area with ozone meter.
First Aid
If a person is overcome by ozone, the following precautions should be
adopted:
a. Remove the patient to a warm uncontaminated atmosphere and loosen
tight clothing at the neck and waist.
b. Keep the patient at rest.
c. If the patient has difficulty in breathing, oxygen may be administered
provided that suitable apparatus and a trained operator are available.
d. If breathing is weak or has ceased, artificial respiration should be
started. The mouth-to-mouth or mouth-to-nose methods are
recommended.
e. Seek medical aid.
