Risk Reduction
The GEW engineering team has considered safety of the equipment at every stage of the design
process. However, certain hazards remain because of the nature of the application. To avoid
accident or injury, operators should be aware of the hazards associated with UV drying systems.
5.6.1. Remaining risks, Hazard reduction and safeguards
The remaining hazards are associated with Ozone, Mercury, Ultra-Violet Radiation (UVR),
moving parts, high temperatures, and high voltages.
5.6.1.1.
Warning!
The UV lamp generates Ozone; the gas is normally ducted to atmosphere
along with the exhaust air. Alternatively, air may be safely discharged to the factory via an
Ozone filter.
Ozone irritates the lungs; if a pungent smell of Ozone is detected check the ducting for air
tightness. Ensure that the ducting is correctly installed and in place at all times. If ozone
filters are fitted, ensure they are changed according to the maintenance schedules set out
in the installation manual.
5.6.1.2.
Warning!
UV lamps contain small quantities of Mercury, which is a toxic substance must
be handled carefully. Always wash hands thoroughly after handling UV lamps. Dispose of
broken lamps safely by the following means:
Wear heavy rubber gloves at all times:
•
Cover the mercury and broken glass with sand.
•
Collect the waste mixture with dustpan and brush, and transfer it to a cardboard box
or other expendable container.
•
To protect the refuse operator, put the container in a thick plastic bag.
Dispose of the bagged container with the normal industrial waste, or in accordance
with local arrangements for disposal of mercury.
5.6.1.3.
Warning!
Ultra violet radiation (UVR) is harmful to skin and eyes. UV dryers have
adequate shielding fitted to prevent accidental exposure of the operator to UVR, but it is
essential to take care when operating the UV drying system. UVR is present in the ranges
UV-A, UV-B, UV-C and UV-V.
Observe the following:
•
Ensure that the shielding is kept in place at all times and is properly adjusted
•
Do not look directly into the lamp head while the lamp is on
•
Avoid prolonged exposure of your hands in the area along the light shields
•
Wear protective clothing and eye protection if prolonged exposure is unavoidable
