Protect the environment

Preserve material assets

No insurance company

compensates for loss of

clients and market share

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%

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

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 …”
