process medium can escape and, depending
on its properties, may lead to personal in-
jury, e.g. (chemical) burns.
Wear protective clothing, safety gloves and
eye protection.
WARNING
!
Risk of burn injuries due to hot or cold com-
ponents and pipeline.
Regulator components and the pipeline may
become very hot or cold. Risk of burn inju-
