Hi All,
We have a customer with an NBN fault in Gympie. Wondered if anyone had any
feet on the ground in the area we could use before we do the 5 hour round
trip.
TIA

It's been a while (~2003) since I read the inergen manual that came with the DC
I was paid to baby sit, but I recall they add CO2 to the gas mix that is
discharged as it forces the Human lung to work harder and cope with the lower
oxygen levels.

Halon has been banned in Australia for about 20 years and it’s not that deadly
as it’s made out to be I had a halon extinguisher in the cockpit of my plane
which would not be ok if it were poison. Most DC in .au use FM200 or inergen.
I’m thinking they used CO2 in the remote station as it
Depends on the fire system. If it’s co2 like in some high power environments it
can be quite dangerous but most other agents are relatively harmless. I can’t
think of a good reason why a data Center would use co2. Most environments with
co2 suppression also have leak detectors and alarms.
who knows how the network is configured and what breaks maybe in place

I don’t believe large amounts but I am aware AAPT had a fibre cut earlier in
the morning, haven’t heard of anything for a few hours though.

Southern Phone are telling me the reason for my NBN HFC internet outage from
8.03am this morning is because of a fibre cut in Sydney. Is this affecting
large numbers of NBN customers?

FM200 gas is banned for new systems in Europe due to HFC pollutants. It is
not a good idea to install it today.
This gas is stored at high pressure - if it leaked you would be aware of
the explosive decompression, even without the alarms.
I can confirm that inhaling this stuff won't immediately
I remember working at an underground DC (Auckland) that had a spontaneous
Halon dump due to a maintenance guy getting too close to one of the sensors
and transmitting on his RT (25 years ago). Tiles went flying, luckily no one
died. So the 1 minute only applies if everything is working. Part of
There are Nozzles that can solve this issue with Inergen & FM200 systems,
such as the awesomely named Hush Nozzle -

It is probably less of an issue these days with the uptake of SSD's, but it is
also worth noting the impact to HDD's this can have.

I remember walking onboard a C-17 Globemaster a year or two ago at
Amberley, still had Halon installed with proper masks sitting next to the
buttons. Probably one of those "exempt" / "critical" use cases I'm sure
being military...

FM200 is still used in a few DC’s in Sydney and Brisbane to my knowledge. But
is costly to replace due to environmental charges.
In Polaris we check all our bottles in accordance to the fire program (which
was approved upon completion with the fire code of that time) which is every
year,
Hi all,
Re the Equinex/NEXTDC bit;
Depends a bit on the detail. Water is cheaper to install and maintain based on
the unlikely event you ever have to use it. I’m not a big fan of mixing water
and electricity though, unless you guarantee you can isolate the power first.
Modern gas systems
My reference to Halon was from nearly 30 years ago … as others have noted it’s
mostly replaced by Argonite / FM200 which doesn’t kill you which may be why the
inductions don’t focus on that so much anymore.
On water – if I recall correctly (it was 30 years ago) IBM was recommending
back then
Pretty sure halon is banned, but fm200 is the gas used these days?

Firstly, the most important advantage of the use of chemical gas - it is
safe for people and electronic equipment. During fire fighting gas is used
in a
The NextDC system reminds me of a similar one that is widely used at a
particular carrier’s exchanges, known as Inergen. I was always taught that
the Inergen system would lower oxygen concentration but not low enough to
incapacitate you unless you stayed in the environment for an extended
period.
Argonite and similar systems work by reducing the oxygen level into the
10-15% range where humans can still breath, but fire can not be sustained.
The chemicals in Argonite are not harmful to humans, so whilst the drop in
oxygen level will certainly have an impact on anyone in the datacenter, it

Unlike Australia, the US doesn't have a ban on Halon (just Halon production),
and it's still possible for existing Halon systems to be recharged using
recycled Halon - especially if they're in a "critical applications".
As of 2011 there were Halon based systems at McMurdo
