Safety Tips for Handling Harmful Gases

8
DANGER!
Do not open any threaded connections in the VOC analyzer gas paths. Doing
so will damage gas path seal integrity.
Combustion gas flowing out of the leak points thus formed in the internal gas
paths can cause fire and explosions (even outside the VOC analyzer itself).
If device-internal gas path threaded connections are opened, a seal integrity
check must be performed with a leak detector (thermal conductivity) when
the device is reassembled.
CAUTION!
The combustion gas path inside the VOC analyzer is checked for leaks at the
factory. No seal integrity testing is required during normal operation.
WARNING!
Some of the gases measured with the analyzer system are harmful to health.
Therefore, the sample gas must not escape from the gas path during normal
operation and maintenance works.
A seal integrity check of the analyzer system has to be performed at regular
intervals.
The diluted exhaust gas must be drained out of the installation room of the
analyzer cabinet.
