It is also very dry.

Waste heat from the diesel gensets providing our electricity, supplemented by additional diesel burners.

It is, we (Davis station) have storage for about a year and a half worth of fuel, and refuel via icebreaker bunkerage once a year.

We use dry chemical extinguishers as a first response. Most buildings have sprinklers and sensitive areas have hi-fog. We have a Hagglund (tracked vehicle) with a water tank and pump and can hook up to the ring main at hydrants around station.
Unlike McMurdo we don't have dedicated fire-fighters so we all got a week of firefighting training before departure and a third of the station is on call at any time as the emergency response team.
dry chem first? what a mess! too bad halon isn't A Thing anymore.
We have CO2 extinguishers near server rooms and switchboards and I believe some of the electrical infrastructure does use gaseous suppression.
But yes, if a fire alarm occurs: the entire station gathers at the muster point while the on call ERT goes to the fire cold porch and the emergency vehicle shelter. From there the on duty team lead and an electrician don fire turnout gear and take dry chem fire extinguishers to the site of the alarm, the first BA team don their breathing apparatus and follow the instructions of the team lead and the second BA team prepares the firefighting Hagglund for deployment.
Do you know of any notable fire events at your station? Are you accessing this site via satellite from there?
> Do you know of any notable fire events at your station?
Not at my station, Davis. Mawson has had a few historically but I think the program overall has avoided any fires that threatened life or property for a few decades.
There was a fire in the engine room of the icebreaker MPV Everest that retrieved the Davis crew a few years ago and the ERT from the station assisted in firefighting.

Yes, there are no fibre cables to Antarctica. We have a connection provided by the government using multiple satellite links as backhaul (ANARESAT, some alternate geostationary satellite and soon Starlink) plus one of the expeditioners* has a personal Starlink that we contribute to and utilise communally.
* unlike other Antarctic programs, Australia has decided to stick with the 'expeditioner' title from the olden days of exploration.
