Decommissioning - Samson EB 2111 Translation Of Original Instructions

10 Decommissioning

The work described in this section is only to
be performed by personnel appropriately
qualified to carry out such tasks.
DANGER
!
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.
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.
Î Allow components and pipelines to cool
down or warm up to the ambient tem-
perature.
Î Wear protective clothing and safety
gloves.
EB 2111/2121/2123 EN
WARNING
!
Risk of personal injury due to pressurized
components and process medium being dis-
charged.
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 thermostat
while the valve is pressurized.
Î Do not start up the regulator until all
parts have been mounted.
WARNING
!
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 regulator. Follow the instructions
given by the plant operator.
WARNING 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.
Î Wear protective clothing, safety gloves
and eye protection.
