1. Safety instructions
The high-pressure mercury vapour lamp emits
ultra-violet light in the UV-A, UV-B and UV-C re-
gions. However, the intensity of the radiation is so
low that, as long as the lamp is used properly, it
presents no risks to those conducting the experi-
ments or any observers.
If there is reason to suspect that the lamp can no
longer be used safely (e.g., if any glass part is dam-
aged), it must be taken out of service immediately.
• Only operate the high-pressure mercury va-
pour lamp with the recommended power sup-
ply unit.
The high-pressure mercury vapour lamp is made of
glass and contains mercury. Therefore there is a
risk of breakage.
• Handle the lamp carefully and do not subject
it to any mechanical stress.
• If the quartz tube is broken, clean up the mer-
cury according to the correct procedure to pre-
vent the escape of toxic mercury vapour.
• If it becomes necessary to dispose of the high-
pressure mercury vapour lamp, local regula-
tions for such disposal must be observed.
UV radiation is damaging to the retina.
• Do not look into the direct light beam or a
reflected beam.
• Always position the safety screen between any
observers and the high-pressure mercury va-
pour lamp.
• Switch off the lamp before changing the ex-
periment set-up.
During operation the body of the lamp will get hot
so that there is a risk of getting burned.
• Do not touch the body of the lamp after
switching on.
• After the experiment, leave the high-pressure
mercury vapour lamp to cool.
• Do not operate the high-pressure mercury
vapour lamp continuously for longer than 10
minutes.
• Allow a break of at least 10 minutes between
successive periods of operation.
Ozone is generated during the operation of the
high-pressure mercury vapour lamp.
• Ensure that there is adequate ventilation dur-
ing the experiment.
