Electric voltage!
During work with the spectrometer, hazards may arise from electric current /
voltage. Observe the following safety instructions to avoid the risk of an electric
shock:
• If you touch the instrument and electrically conducting parts, such as machines or
devices, simultaneously, voltage can be generated from possible potential
differences which is perceptible but non-hazardous.
• Never spark wet or moist surfaces, since there is a risk of a short circuit!
• Never spark without a clamped sample!
• Never spark without the spacer screwed into the spark stand!
• When the excitation source is switched on, avoid any contact with the spark
electrode!
• When working at the spark stand, e.g. for changing the electrode, do in any case
switch off the excitation source.
• Do not touch the sample during measurement!
• During sparking, do not, under any circumstances, introduce a conducting object
into the proximity of the spark stand opening!
• During sparking, do not, under any circumstances, remove a conducting object
from the spark stand opening!
• With the spark stand opening open during sparking, do not, under any
circumstances, bring a part of your body into its immediate vicinity!
Hot surface!
Small and/or thin samples can become hot during sparking.
•
During measurement of small or thin samples, wear protective gloves!
Risk of injury due to UV radiation!
During the analysis of samples that do not entirely cover the spark stand opening (e.g.
wires), spark light can emerge. Your eyes can be blinded by the light and the high-
energy UV radiation can damage your eyes.
•
Never look into the arc!
• Wear suitable eye protection during work.
Wear ear protection!
During the analysis of samples that do not entirely cover the spark stand opening (e.g.
wires), the sound generated upon sparking (measuring) exits through the gap.
•
For sparking samples that do not entirely cover the spark stand opening wear ear
protection.
Escaping gases!
When measuring hazardous substances, there is a hazard from escaping gases or
vapours.
•
The operator must know what substances he is working with.
• The operating company must provide for suitable protective measures (e.g.
exhaustion). (Metal dusts are primarily released. Those are usually washed in the
washing bottle and do not escape.)
