Special protective measures (as required)
3.4.1
Protecting against dangerous sample gases
If the sample gas can be dangerous to health and/or corrosive:
▸
Make sure no dangerous situations can arise should a gas leak occur.
▸
Check:
– Whether a gas detector must be installed at the installation location.
– Whether the enclosure must be purged continuously with a neutral gas during
operation (with monitoring the discharged purge gas as required).
Install appropriate additional devices as necessary.
▸
Check gas paths regularly for leak tightness.
3.4.2
Protecting against corrosive atmospheres
When the atmosphere at the installation location can contain corrosive gases:

CAUTION: Accident risk through inadequate fastening of the enclosure
▸
Observe the weight of the enclosure of approx. 30 kg.
▸
Observe the sufficient carrying capacity of the wall or the rack.
Use adequate “Cavity dowels metal” with an allowable load of at least 30 kg for
gypsum plasterboard walls.
