What to do in case of operating faults

Note
See technical safety information on
page 4.
Generally, the operating instructions
should be observed regarding action in
case of operating faults. The following
highlights some aspects that are the
result of general operating experience.
If steam lines, fittings/valves and other
operating equipment on the steam boiler
system leak, and these leaks cannot be
remedied immediately, limit their effect,
identify and monitor them.
Areas at risk should only be entered if
this is requested by the authorised per-
son and the safety measures required for
work inside the areas at risk have been
implemented.
System parts that have been shut down
as a result of a fault must only be started
following the instructions of the person
with the appropriate responsibility, once
the cause for the shutdown has been
removed and the system components
have been tested locally prior to the new
start.
Immediately shut down the steam boiler
system and inform the supervisor as
quickly as possible if a boiler condition is
suspected that could cause a dangerous
condition. This applies particularly if, for
example
■ A boiler wall shows signs of glowing
red hot or of a deformation anywhere
■ The safety valve cannot be made to
respond correctly
■ A correct operation of the controllers,
the limiters or flame monitors cannot
be ensured
■ A fuel leak is recognised
Utilisation and operation
■ Irregularities in the combustion opera-
tion or a deflagration have/has occur-
red
■ Medium is leaking from the pressure
part of the boiler
If dangerous conditions for boilers exist,
shut off such conditions from boilers con-
nected in parallel.
If emergency operation should be ena-
bled for operational reasons, agree the
required measures with the approved
inspection body and the manufacturer.
