NOTICE
The system may be damaged and contaminated due to the failure of the purge
air!
If the purge air fails, the lens may quickly become contaminated and the flame monitor
may overheat due to a build-up of heat and be destroyed. Therefore:
Make sure that
▶ the purge air supply is operating reliably and smoothly (even when the system is
stopped).
▶ you immediately detect a failure of the purge air.
▶ the flame monitor is protected by a valve or dismantling process in the event of a
purge air failure.
2.3 Qualified personnel
WARNING
Danger of injury due to insufficient qualification!
Incorrect use can result in serious personal injury and material damage. Therefore:
▶ Ensure that work is only ever performed by suitably qualified specialised person-
nel.
This operating manual assumes that the personnel performing the work have the ne-
cessary training and knowledge. Only personnel who have this knowledge are con-
sidered to be qualified and authorised in this operating manual.
●
Specialised personnel
are those who because of their specialist training, know-
ledge and experience, coupled with knowledge of the applicable regulations, are in
a position to perform the work assigned to them and make independent judge-
ments of the potential hazards.
● An
electrician
is an individual who, because of their specialist training, knowledge
and experience, coupled with knowledge of the applicable regulations, is in a posi-
tion to perform work on electrical equipment and make independent judgements of
the potential hazards. Electricians are specifically trained for the working environ-
ment in which they are employed, and they are also familiar with the relevant
standards and regulations.
●
Persons with electrical training
are those who have been instructed by a special-
ised electrician on the work assigned to them and the potential hazards involved
with improper conduct, and on the necessary protective equipment and protective
measures.
●
Knowledge of explosion protection
is required by all persons carrying out work on
the flame monitor in any kind of hazardous area. This requires knowledge of the
detection and prevention of explosion hazards in accordance with the explosion
protection document. Employees must know how to avoid acute risks and where
work can safely be performed on the devices.
The specialist knowledge on explosion protection must comply with the national
regulations at the place of installation of the device (ATEX, FM, CSA, ...). The per-
mit and qualification or certification required to work in areas at risk of explosion
are regulated in national regulations or laws.
The operating company must ensure that the aforementioned specialised personnel
are given up-to-date instructions on the following:
● Precise information on the operating risks and their prevention.
● Knowledge of system conditions, applicable standards, regulations, directives, op-
erating instructions and accident prevention regulations in the context of the work
assigned to them.
