Fire detection and protection systems
The stations have been designed with fire protection in mind. The buildings at the continental stations are of a steel frame construction with external insulated panels. Most buildings are connected to site services which include heating hot water and a sprinkler supply. All are sufficiently spaced from each other to lessen the risk of a fire spreading.
There are fire hose reels in some structures and fire dampers have been installed in the HAVC ducting, however no smoke ventilation systems are installed.
Every building is equipped with portable fire extinguishers including water, foam, dry powder and CO2. Other fire extinguishment systems include:
- Sprinklers – wet systems in science, operations, sleeping and living quarters.
- Water Deluge – dry system, main power house sub-floor.
- Hi-Fog – main power house engine hall and emergency vehicle shelter.
- Pyrogen – communications, electrical ring main buildings and stand alone isolated containers.
- Wet Chemical – kitchen range hood
To minimise the risk of fire, station fuel supplies are stored some distance from the station buildings. Stored in two fuel farms, comprising multiple 90 000 litre tanks, all the fuel is contained in a single bunded area. The fuel is transferred to bunded settling tanks adjacent to the power houses.
