The gas sampling system is designed and built in such a way that personnel
can work with it without any risk. Despite all precautions, however, unfore-
seeable accidents may nevertheless occur in unfavorable circumstances. If
cooling water pipes or compressed-air pipes burst, shut down the gas sam-
pling system and secure it against being switched on again. If errors are de-
tected, shut down the system and secure it against being switched on again.
Before approaching the gas sampling system, wait until the entire cooling
water or the entire compressed air has been evacuated.
If the switched-on gas sampling system poses a danger, proceed as follows:
Aim
