Safety
— 12 SPECTROLAB — 30.07.2015
Caution! Toxic!
The sparking process produces a black precipitate (metal condensate). The
condensate could be toxic or flammable, depending on the sample material.
Protective gloves and safety goggles must always be worn when
cleaning in the spark stand and when cleaning the gas-washing bottle
the filter bottle. This also applies when replacing the filter insert.
When disposing of the condensate, compliance with legal regulations is
mandatory.
Metal vapors may be generated from the sample material. Depending on the
sample material, these vapors may be toxic, e.g. in case of heavy metals.
Ensure that protective equipment is worn in such cases, e.g. a
breathing apparatus and extraction equipment is installed. The
protective methods must ensure that the applicable threshold limit
values (TLV) and/or comparable national standards are not exceeded.
Caution! Risk of electrical shock!
When the instrument is switched on, there is a risk of an electric shock when
the electrode is touched or when the sample is removed during a
measurement.
Never touch the sample while a measurement is in progress.
Avoid any contact with the electrode when the instrument is switched
on.
Shut down the source (plasma generator) during all work on the spark
stand.
For voltage ranges, see page 13.
Caution! Risk of burns!
Contacting the electrode increases the risk of burn injuries. During normal
operation, the electrode will heat up to several hundred degrees.
Never touch the electrode with your bare hands, even after shutting
down the spectrometer. Always use pliers.
A sample can get hot if it is measured several times.
Touch the sample only after is has sufficiently cooled.
