10 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
equipment that may burst when handled
incorrectly. Flying projectile fragments or the
release 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
Shut off an external control line.
Î
Drain the process medium from all the
plant sections affected as well as the reg-
ulator.
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.
Î
Do not loosen the external control line
while the valve is pressurized.
Risk of hearing loss or deafness due to loud
noise.
Noise emission (e.g. cavitation or flashing)
may occur during operation caused by the
process medium and the operating condi-
tions.
Î
Wear hearing protection when working
near the valve. Follow the instructions
given by the plant operator.
Risk of personal injury due to residual
process 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.
Î
Wear protective clothing, safety gloves
and eye protection.
