Halon was banned at the same time as CFCs in aerosols and
refrigerants because it's an Ozone depleting gas. There should not
be any Halon datacentres anywhere in Australia. Probably not
anywhere in the world, tbqh.<br>
<br>
Aviation is an exempt use, which is why you saw it on your C-17. You
can buy fixed or portable halon systems intended for deployment in
aircraft even today (for example:
<a class="moz-txt-link-freetext" href="https://www.aircraftspruce.com/catalog/pspages/h3rhalon.php?clickkey=11303">https://www.aircraftspruce.com/catalog/pspages/h3rhalon.php?clickkey=11303</a>
-- one of the few few ways you can acquire ozone depleting gasses as
a retail customer in 2018!)<br>
<br>
CO2 is a hazardous gas, and should be pretty rare for fire
suppression. Possible that there are still some small and/or ancient
systems out there, but risk assessment under OHS&W legislation
ought to have seen them all replaced by now.<br>
<br>
Datacentres in Australia will be using FM-200 or Inergen. FM-200 can
be stored in compressed gas or liquid; obviously liquid means the
storage takes up significantly less volume. FM-200 has fallen out of
favor during the last five years because it's a greenhouse gas,
which makes me regret not having a crystal ball when I was putting
it in datacentres ten years ago :-)<br>
<br>
Both of them are engineered solutions which take the room volume
into account. The goal is to add enough gas to the room to drop the
oxygen content from 19% to something in the 15%-17% range, which is
low enough to extinguish most fire but high enough to sustain human
life. If you're in the room when it goes off you'll end up
uncomfortably short of breath (and probably very cold!), but you
shouldn't suffocate if the system has been designed properly.<br>
<br>
A complete system will generally also include a pre-action dry pipe
deluge sprinkler system which can trigger if the gas fails to
extinguish the fire.<br>
<br>
... and a good insurance policy. If any of these systems go off,
might end up with system loss and/or data loss. Hard disks don't
like rapid pressure changes or large quantities of water, so all
bets are off once the VESDA trips out.<br>

the most important advantage of the use of

is used in a concentration not to be harmful to
human health and life. When using the FM200 gas
