WARNING
Risk of explosion due to improper use
A device in the standard version must never be used in hazardous areas.
Explosive gas mixtures (e.g. ammable gases together with air or oxygen in a potentially
explosive ratio) must not be measured with this analyzer.
If the sample gas could contain ammable components above the lower explosion limit (LEL),
we recommend that you only use analyzers with piped gas paths.
WARNING
Wetted parts unsuitable for the process medium
Danger of injury or damage to device.
Hot, toxic and aggressive process media may be released if the media is not suitable for wetted
parts of the analyzer.
• Ensure that the material of the device parts wetted by the process medium is suitable for the
medium. Read the information in the technical specications of the respective manual!
WARNING
Harmful gases
Danger to personnel, system and the environment can result from introducing harmful
(corrosive, ammable and/or poisonous) gases into the device. If this should be required for the
measuring task of the device, you must take the following measures:
• Take into account the safety measures according to the German Occupational Safety Act
(Arbeitsschutzgesetz - ArbSchG) or similar international regulations. These safety measures
must be coordinated with a local specialist. In particular, this includes measures to prevent
any potential release of gases from the internal gas path (containment system) as well as
their monitoring and disposal.
• Ensure that the discharged gas is treated according to the applicable local laws.
• When you measure gases with ammable components at concentrations above the lower
explosion limit (LEL), we recommend that you only use piped devices (see also report BB-
EG1-KAR Gr02X from TÜV Süddeutschland).
• Purge the device or the plant with a purging gas (inert gas). The gas displaced by purging
must be collected using appropriate equipment and disposed of environmentally-friendly
via an exhaust line.
