<p style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 16px;">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".<br>
</p>
<div><br>
As of 2011 there were Halon based systems at McMurdo (https://www.nfpa.org/News-and-Research/Publications/NFPA-Journal/2011/September-October-2011/Features/Nowhere-to-Go) - it may well be the case that these are still pending conversion.<br>

</div>
<div>The use of personal gas detectors is common in Oil and Gas when working in areas that may contain dangerous levels of CO2, Chlorine, Methane or Sulphur - perhaps it's time to see if these units can be adapted to detect suppression agents as well.<br>

around evacuation in the event of a triggered alarm, any system that silently deploys a gas based fire suppressant silently would be against code and highly illegal.</span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Every data centre has a fire suppression system. We're not used to thinking of this as a hazardous environment, but consequent to
<a href="https://www.theguardian.com/world/2018/dec/12/antarctica-two-technicians-dead-mcmurdo-station-ross-island">
two techs being found dead working on a fire suppression system in Antarctica</a>, I find myself wondering yet again, why there aren't more stringent controls around the fire suppression systems in data centres: viz - when you enter a data centre, how confident
can you be you're not going to be quietly asphyxiated?<br>

Kind regards<br>
