DANGER
!
Risk of bursting in pressure equipment.
Regulators and pipelines are pressure equip-
ment. Improper opening can lead to bursting
of the regulator.
− Before starting any work on the regulator,
depressurize all plant sections affected as
well as the regulator.
− Drain the process medium from all the
plant sections affected as well as the regu-
lator.
− Wear personal protective equipment.
WARNING
!
Risk of personal injury due to residual pro-
cess medium in the regulator.
While working on the regulator, residual
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-
ries.
