2. Safety
WARNING!
For hazardous media such as oxygen, acetylene, flammable
or toxic gases or liquids, and refrigeration plants, compres-
sors, etc., in addition to all standard regulations, the appropri-
ate existing codes or regulations must also be followed.
With pressure gauges which do not correspond to a safety
version per EN 837 highly pressurised media might leak out
through the possibly bursting window in case of a component
failure.
WARNING!
Residual media in dismounted pressure gauges can result in
a risk to persons, the environment and equipment.
Take sufficient precautionary measures.
