Using cardiac pacemaker
Physical processes during operation of high voltage may endanger persons
wearing a cardiac pacemaker when near these high voltage facilities.
Firefighting in electrical installations
• According to regulations, carbon dioxide (CO2) is required to be used
as extinguishing agent for fighting fire in electrical installations.
• Carbon dioxide is electrically non conductive and does not leave
residues. It is safe to be used in energized facilities as long as the
minimum distances are maintained. A CO2 fire extinguisher must be
always available within electrical installations.
• If, contrary to the regulations, any other extinguishing agent is used
for fire fighting, this may lead to damage at the electrical installation.
Megger disclaims any liability for consequential damage.
Furthermore, when using a powder extinguisher near high-voltage
installations, there is a danger that the operator of the fire
extinguisher will get an electrical shock from a voltage arc-over (due
to the powder dust created).
• It is essential to observe the safety instruction on the extinguishing
agent.
• Applicable is DIN VDE 0132.
WARNING
Dangers when working with high voltage
Working on high voltage systems and equipment – especially in non-
stationary operation – requires particular care and safety-conscious action
on the part of test personnel. VDE regulations 0104 on setting up and
operating electrical test systems, as well as EN 50191 and national
standards and regulations must be strictly adhered to.
• The test system generates a dangerous test voltage of up to 40
resp. 60 kV
PEAK
.
• The test system may not be operated without supervision.
• Never fail to use safety equipment or put it out of operation.
• Operation requires minimum two people whereas the second person
must be able to activate the emergency switch in case of danger.
• To prevent dangerous charge accumulation, earth all metal parts in
the vicinity of the high voltage equipment.
