2.2 Safety information
Toxic and/or corrosive gases
When measuring toxic or corrosive gases, leaks in the gas path may cause harmful
sample gas concentrations to accumulate in the system or in individual analyzers.
Health risks up to and including danger to life exist in the case of the following sample
gas components:
• Carbon monoxide (CO):
• Carbon dioxide (CO
• Sulfur dioxide (SO
• Nitric oxide (NO):
• Nitrogen dioxide (NO
To prevent a poisoning hazard or damage to analyzer parts, the relevant analyzer or the
system must be purged with inert gas (e.g. nitrogen). The gas displaced by purging
must be collected using appropriate equipment and disposed of environmentally-
friendly via an exhaust line.
Harmful substances in the condensate
The condensate at the sample gas cooler or condensation trap can be corrosive,
depending on the composition of the sample gas (e.g.: through SO
When you dip litmus paper into the condensate it will turn red.
• Wear protective clothing, protective goggles and protective gloves when handling the
• Prior to its disposal, dilute the condensate with tap water until it turns neutral and
