[AusNOG] Warrnambool Exchange Fire Investigation Report

[Michael Risby]

Well if you use the Quakers Hill aged care facility as a model it's at the point where it will cost $5,000 per bed to retrofit a sufficient fire suppressant system (at an absolute minimum), multiplied by an average of 50 beds per aged care facility not including any booster pumps if required, maintenance and service contracts, list goes on. Think about the size of some exchanges.

Also being a telecommunication room, a VESDA system (or one alike) would be ideal. A dry pipe system also, not even sure if Halon still gets installed or is even allowed to be used.

Might be more beneficial to have someone go around to each exchange and defect the electrical installations. Incorrect cable size, segregation, conductor type, etc..

It's more complex than that - a lot of POIs are, in fact, Telstra exchanges. So we may in fact need Telstra to install fire suppression not NBNCo or we'll still lose (one O) a POI in future ...

I imagine with the benefit of hindsight they are now doing a cost/benefit on each exchange and seeing if its worth putting in.
Its probably cheaper for them to loose service for a while and fix it rather than put eleventy million halon systems in.

I do hope NBNco is doing a lessons learnt from this though, their concentration feels like its going to be much higher, loosing a POI for a couple of weeks would be a "bad thing".
I wonder at what point in the network it would be feasible to slap a wireless/satellite/whatever on top of a box and replace the POI (at a reduced rate) until the POI is back up.

No, but cant say I was particularly looking for them. I suppose I kind of assumed there might be something like a gas based system in there though. I mean, theres a lot of expensive gear, you'd think you'd want to avoid damaging it, and/or losing the building. Imagine if they had to rebuild, the outage would have lasted months, instead of the weeks they managed to restore service in.

Ignorance aside, and apart from the obvious "it would cost a shit load to add it to them all", are there any particular reasons why major regional exchanges wouldn't have fire suppression?

To me it seems that places like Warrnambool and sites with similar significance (the ones Telstra refer to as KTPs) could probably benefit from some kind of suppression. These events might be rare, but they have a big impact when they happen.

Is it just me, or are there zero mentions of fire suppression systems?
There were unlikely to be any.

You've been in country telephone exchanges before. Do you recall ever seeing a sprinkler head?
