Decommissioning
The work described in this section is only to
be performed by personnel appropriately
qualified to carry out such tasks.
Risk of bursting due to incorrect opening of
pressurized equipment or components.
Regulators and pipelines are pressure equip
-
ment that may burst when handled incor
-
rectly. Flying projectile fragments or the re-
lease of process medium under pressure can
cause serious injury or even death.
Before working on the regulator:
Î
Depressurize all plant sections concerned
and the regulator.
Î
Drain the process medium from all the
plant sections concerned as well as the
valve.
Risk of burn injuries due to hot or cold
components and pipeline.
Regulator components and the pipeline may
become very hot or cold. Risk of burn inju
-
ries.
Î
Allow components and pipelines to cool
down or warm up to the ambient tem
-
perature.
Î
Wear protective clothing and safety
gloves.
DANGER
!
WARNING
!
Risk of personal injury due to pressurized
components and process medium being
discharged.
Incorrect opening of pressure equipment or
mounting parts may lead to the process me-
dium escaping to the atmosphere.
Î
Do not loosen the control line while the
valve is pressurized.
Î
Do not start up the regulator until all
parts have been mounted.
Risk of hearing loss or deafness due to loud
noise.
Noise emission (e.g. cavitation) may occur
during operation caused by the process me-
dium and the operating conditions.
Î
Wear hearing protection when working
near the valve. Follow the instructions
given by the plant operator.
Crush hazard arising from moving parts.
Î
Do not insert hands or fingers between
the set point springs while the regulator
is in operation.
Î
Do not insert hands or fingers between
the pillars and set point springs while the
regulator is in operation.
Î
Do not insert hands or fingers between
the spring plate and crossbeam while the
regulator is in operation.
