WARNING!
Physical injuries and damage to property and the
environment caused by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene,
flammable or toxic substances), harmful media (e.g. corrosi-
ve, toxic, carcinogenic, radioactive), and also with refrigera-
tion plants and compressors, there is a danger of physical
injuries and damage to property and the environment.
Should a failure occur, aggressive media with extremely high
temperature and under high pressure or vacuum may be
present at the instrument.
For these media, in addition to all standard regulations,
the appropriate existing codes or regulations must also be
followed.
▶
Wear the requisite protective equipment (see chapter 3.6
"Personal protective equipment").
▶
With hazardous media, the drain valve may only be
opened for a short time so that the condensate can run out.
