Ozone Gas
Ozone (O
3
) is a colorless gas that is generated by
the reaction of short-wave UV light (around
200
−
220 nanometers) with air, and it occurs
whenever high-energy electrical discharge is
present.
Ozone readily reverts to breathable oxygen when
mixed with atmospheric air. Ozone should be
removed from the UV source via a sealed duct and
discharged to atmosphere according to local
regulations. The discharge location should be
away from pedestrian walkways and window
openings and should be well above the average
human breathing height for the area.
Regular ozone checks should be carried out every
three months using an ozone meter.
Recommended levels of ozone in the atmosphere
of a factory should not exceed 0.1 parts per
million (PPM). This level is easily obtainable if
factory recommended exhaust rates are followed.
Ozone has a very distinct, strong odor even at low
levels. Immediate ozone checks should be made if
an operator can smell ozone. Most people can
smell ozone at about one third the maximum
allowable 0.1 PPM level.
Ozone exposure will cause headaches and fatigue.
It will also irritate the mouth and throat.
Overexposure can lead to respiratory infections.
If ozone is detected,
1. Shut down the UV system.
2. Check exhaust ducting for leaks.
3. Check the operator working area with an ozone
meter.
If a person is overcome by ozone,
S
Move the individual to a warm uncontaminated
atmosphere and loosen tight clothing at the
neck and waist.
S
Keep the individual at rest.
S
If the person has difficulty breathing, oxygen
may be administered provided that suitable
apparatus and a trained operator are available.
S
If breathing is weak or has ceased, artificial
respiration should be started.
S
Seek medical assistance.
High Temperature
UV curing systems generally run at
extremely high temperatures. A sudden
shock from touching a high temperature
surface might cause an operator to jump or
take his attention away from other potential
hazards.
When shutting down UV equipment for
maintenance, allow the equipment to cool before
beginning work, or wear protective gloves and
clothing to prevent burns.
High Voltage
The UV curing equipment operates at high voltages
up to 5000 Vdc. The system uses high-voltage,
self-discharging capacitors.
Once power to the
power supply is shut off, the capacitors need
120 to 130 seconds to discharge.
If any electrical faults develop, the operator should:
1. Switch the equipment off immediately.
2. Make no attempt to service the equipment.
3. Call a qualified electrician, trained to service
this type of equipment.
