Risk
Main fire risk of overheating and oil ignition
presented by faults (transformer short circuits)
Prevention and detection
Transformer automatically deactivated when
overheating is detected
‘Buchholz Relay’ ensures prompt identification
of required cooling
Water spray extinguishing system can be
automatically activated by relay
Protection:
Simultaneous and homogenous distribution of
water prevents fire from spreading further
Operation can be re-initiated quickly to ensure
a constant power supply to the grid
Maintenance:
System tests can be
performed during normal
operation of transformers

Exposure to concentration > 17%
(CO2 fire suppressant use) Loss of controlled
activity, unconsciousness, convulsions, coma, deat

Exposure to concentration 10 - 15%
Unconsciousness, drowsiness, severe muscle
twitching, and dizziness within several minutes
Exposure to concentration 7 - 10%
Unconsciousness, dizziness, headache, visual and
hearing dysfunction, mental depression, shortness
of breath, and sweating within a few minutes to an

Exposure to concentration 4 - 7%

CO2 SYSTEM - LIFE SAFETY CONSIDERATIONS
Minimum concentration for fire fighting via total flooding is 34% concentration
© Minimax 201318 / 25
CO2 SYSTEM - COMMISSIONING
Commissioning by trained personnel to
meet approval requirements
Integrity test for each hazard area;
validation of design concentration (&
hold time for total flooding systems)
Operational checks of all devices,
incl. detection, alarm & activation
Check for proper labelling of devices
and protected areas, warning anyone
of possible CO2 discharge; signage
must be present to vacate area when
alarm sounds
Complete inspections of the system
and hazard area to ensure the
system meets specifications and is
appropriate for the type of hazard
© Minimax 201319 / 25
To be considered
Without an operational CO2 fire
extinguishing system, your turbines
cannot be restarted
False alarm can lead to a complete
discharge and may leave you empty-
handed, unless 2nd set of cylinders is
kept on site
Recommendation
Test with local supplier to validate
guaranteed refill & delivery times
If not satisfactory (more than 24 hrs),
purchase a spare set of cylinders

MURPHY’S LAW - IMPORTANCE OF FULL DISCHARGE
Installation company certified clean
installation of pipes and fittings with no
excess hemp; all fittings double
checked for tightness; pipes blown out
with compressed air in surges; door
fan test passed the enclosure.
Full discharge FAIL; nozzles blocked,
fittings leaked, 1” pipe blocked solid
Best practise is one full discharge
every five years, minimum after
installation and/or changes
“When things can go wrong, they will …”
