EXPLOSION HAZARD
Inspection, maintenance and service must be carried out considering
all related standards e.g. for „Inspection and maintenance of electrical
installations in hazardous areas“or „Equipment repair, overhaul and
reclamation.
EXPLOSION HAZARD BY OPEN HOUSING
Service or replacement of safety related components or requiring to open
the instrument are permitted only if no hazardous atmosphere is present
and both the instrument and connected circuitry are de-energized!
Depending on the local regulation this may require a competent hot work
supervisor to issue a hot work permit.
Consider the waiting time statement on the front door label before opening,
if the analyzer is congured for vapor recovery measurements!
EXPLOSION HAZARD BY UNAUTHORIZED REPLACEMENTS
After maintenance or replacement of parts concerning explosion protection
an authority on explosion protection has to verify that the analyzer still meets
the requirements for explosion protection before it is switched on again.
Parts essential for explosion protection must not be repaired, they must be
replaced if defective!
The authority has to issue a certicate for this and/or attach a test label to
the equipment before startup after maintenance or replacement of parts.
