So,  what is your legal authority to extinguish those types of burns?

Pip

I seem to remember reading something like
"...a person shall be in attendance at all times whilst the fire is alight, with
the capability & equipment to extinguish it should need arise." 

Might have been in an Act or Regulation or some other trivial bumph.   :wink:
Would that be adequate authority ?

We had our first call in almost two months on the weekend.... and we have had less than two thirds of our average annual call rate ...  :-(
Pip

G'day Pip
We're tracking about average - high twenties.
Given that during the last really hot season 10 or so years ago we had over 70 calls, I would have expected it to have been a few more.
About 30 calls that year were arson in one form or another.
I guess SAPol are having some successes.
And maybe the idiot factor took a brief holiday...

Report 'em to SA water and they should (hopefully) fix it.

They will come & fix it.  Eventually.
Up our way is a trunk main with cathodic protection measuring points every 200M or so.
These are a matchstick with an orange head instead of a red head.
The cats eyes installers couldn't tell the difference so they marked all these as well.
It took about 6-8 weeks, but they did come back & remove all the wrongly applied cats eyes.

until the new one is online. It is the CFS remember. Usually someone drives the new one in and the old one straight out the door. Or of you are Mt Barker they drive in a type 2 and take your rescue and 24P.

Eden dug their heels in about that when the Louisville was replaced with the Type 2. It spent several weeks in a spare bay at another brigade before Eden "released" it back to SAFECom.  The massive inertia of beaurocracy can be resisted/deflected/delayed if determined enough, & willing to reciprocate the paperwork bombardment.

at least 2 gigabytes should be the definate minimum to be classed as broadband...

256kb is even useless if ya cant "Stretch" your arms for more than 60mins.

Once upon a time, "Broadband" was rigidly defined as a data stream greater than 2MB/S.  But that was before the media & marketing people got involved & mangled it into a marketing term instead of technical one.  :-(

Can live with a bottom-end plan of low monthly volume being available to those who want it.  Know a few people who have them & have no trouble staying under their cap. Mostly older folks who do a small amount of email & browsing per month, update their virus definitions religiously once a year whether they need it or not. And never download updates to OS or other programs... (it ain't broken, don't play with it.) 

It's the adverts which bundle those low volume plans with high volume applications like VoIP which are irresponsible, borderline criminal in my view.

Aircranes offer a better service than airtractors. they can pick up from anywhere without landing, dams, even a pool, and can hold 3 times an air tractor.

all absolutely true !
Then there come some conditional truths Gilly.

Quote
They could put at least 10 times the water on a fire than an air tractor over the same time period. (and in most places, water sources are fairly close by).

My opinion - it is only an opinion since I wasn't actually under it, merely noticing cycle time from the NE flank of the Willunga fire...

The Crane made a big difference at the Willunga fire.

(It hurts to say that - I'm a AT802F fan).  Because it was in the hills with a lot of decent farm dams available close by, it was dropping 8,000+ Litres every five minutes or so. The AT's take time to fly to an airstrip, land, load (2 mins with the latest pumps at Cherry Gdns) take-off, return to the FG & be tasked by the AAS... maybe 3,000L per 20 mins. Quicker if the fire is closer.

Away from the Hills & the farm dams, the AT's probably have the edge.  The Crane is slower so its cycle time would be much longer.

Quote
They can also direct water easier, are safer than fixed wings, can dump more concentrated loads (lower speeds).

Any rotary winged aircraft is inherently more dangerous than a fixed wing one. If the big wheel stops turning, it's a brick...
On the other hand, the ten or so AT802's that would be needed to do the job of the one Crane ***in this one situation*** would need careful management to avoid bumping into each other.
It would also need some investment in reloading & refuelling infrastucture at the various airbases.

Quote
People are too willing to "shoot down" things due to cost, without really looking at the advantages.

You noticed that too, huh !!  Mind you, has anyone actually seen a cost comparison between one Crane @ between $12K & $22K / hour flying time depending upon who you believe, plus stand-by costs, vs. a pack of AT802Fs at whatever their hourly rate is ?

The operating costs of 10 AT802Fs per hour may possibly be comparable to one Crane. But 10 x 802's can be at 10 different fires just as easily as beating the living daylights out of one fire...

The other thing is that for every hour of flight time, the Cranes have to spend much more down-time for maintenance - something like 2:1.  If one of 10 AT's breaks, you can still run at 90% of their capacity. If a crane breaks, you run at 0% of its capacity until fixed..

Quote
I'm more than happy to have an air-crane here as they are so effective. The government is not buying one for $30m, just having one here for the whole season (which was done basically this year anyway...).

We got lucky this year - it rained interstate, & a mate in RFS Blue Mountains was bragging that their max temp hasn't exceeded 30C at all in 2008... Could have very easily squabbling with Vic & NSW for it & come away with nothing.

Anyway, enough with grizzling from me. 
There's no question that the Crane is good.
Just whethwer it represents the *best* value for our money.


cheers

At home I have Vista on a new cheapo Compaq laptop & XP on an old lower specced desktop.
Had to increase the RAM in the laptop for Vista to run acceptably. The desktop is still quicker despite having half the RAM & 2/3 the processor speed.
At work I have XP on a new desktop - really fast & is stable as a rock.

Some things Vista are very good.  Plug in a new piece of hardware to the vista machine & it automatically finds & instals drivers & etc for it. XP doesn't do this.

Other things...
Vista is far less stable than XP.  The Vista machine crashed more times in the first  weeks than the XP box has in two years. Twice weekly defrag seems to have helped.
Vista's version of Windows Explorer (File Manager) is a Bad Thing - no tree display. Which makes drag-&-drop, and file & folder sharing harder.

Documentation of incompatibilities is poor. Couldn't network them initially. Turns out Vista uses a different neighbour discovery protocol & a patch has to be added to XP for it to be visible to a Vista PC.

Overall I like XP better but, for me, the grief of hunting up XP drivers for the laptop far outweighs Vista's diappointments.

Does anyone use Virgin Broadband / Phone for home facility ? I have been debating it, but a two year contract is putting me off.

friends recently got burnt with it.
the offering in the paper has a low data cap & expensive excess per MB rate.

VoIP = two-way streaming data.

I don't think there is anything in OZ, but I could be wrong. A few years ago we had the Canadair aircraft here, they were designed for this purpose but our reservoir's weren't big enough to take this aircraft, and if the swell was 1/2 metre or more it could not collect any water from the sea, and would have to be filled on the ground. I think they could carry 30,000litres of water but not quite sure, it was a few years ago now, but someone on here might remember.  :-D

The Canadairs are the ones that were tested & rejected. the CL-215 could lift 4000L & the CL-415 can lift 6000L.  In 2001 when I researched it, the CL-415 cost just shy of AU$30M each, needs a crew of 2, & if not operating off a lake (haven't seen many of them in rural SA), need lots of concrete runway (haven't seen many of them either). 
http://www.bombardier.com/index.jsp?id=3_0&lang=en&file=/en/3_0/3_3/3_3_0.html

By comparison, the AT802F lifts around 3000L, cost AU$1.2M & can operate from any paddock.  http://airtractor.com/at-802f

Do the maths....  :-)

AirTractor do a seaplane kit for the AT802F that lets them skim & scoop. They call it the "Fire Boss".  Col Pay was killed late last year testing one in the Hunter.  :-(

SA Firefighter General / Re: Most important tool on the truck.
« on: March 17, 2008, 12:52:47 AM »
I have used both and prefer the TFT. It produces a better stream across the range, and produce an awesome fog pattern, and works better with lower flows and pressures, still providing a decent stream de to the automatic apeture. They are also low maintenance and seem a higher quality. we use both the 10-125 and the 50-350 and both sizes work very well.

Disagree on some points.  When a TFT has enough pressure, it is certainly a simpler branch to use - volume & pattern controls only.  However a manual branch eg Akron can often be persuaded to work at very low pressures when TFT simply can't produce more than a trickle.  Like at the end of 16 lengths of 25mm up a hill off a GAAM-300, or direct off a hydrant that someone else is using further down hill.

At "normal" pressures, the flow around the TFT's bullet valve is technically superior to the Akron's ball valve. The control-freak in me likes to to tell the branch what I want it to do rather than the other way around...  So my preference is manual.  Akron, Protek, Fogmaster.  Allasame me. Squirtim plenty good water.

SA Firefighter General / Re: fire hose
« on: March 17, 2008, 12:19:53 AM »
Difference is more like percolating vs non-percolating hose.

Percolating is self-protecting when dragging it around a hot bush-fire. Weeps water so it won't burn through readily, & minor pin-pricks from barbed wire etc don't really matter. The cost is that it has significantly higher friction loss, & needs a bit of extra care to keep it from rotting.

Duraline & other non-percolating hoses have much lower friction losses - many more lengths can be added.  Most are much higher pressure hoses to begin with so are less likely to burst.  This increases the number of lengths that can be added & still have >700KPa at the branch.

choose the tool that does the best job for the risks faced by the brigade.

Urban interface in the Hills might be better off with non-percolating to tolerate the pump pressures needed to get up & over hills. Mallee brigade might be better off with percolating to protect the hose from hot spots & stumps & fences & etc.

SA Firefighter General / Re: Appropriate Levels of Response.
« on: March 17, 2008, 12:07:09 AM »
I got litle understanding of CFS/MFS/SES responses, but why isnt there a system set up like SAAS. Where each truck is a specific crew and a specific crew gets paged for a job/case, and if the incident is big enough (or requires it) additional crews get responded. Surley you don't need an MFS truck and 2 CFS trucks at a MVA plus SES. I have seen many incidents where only one fire (or rescue) crew is required and half the service has turned out.

G'day Knackers.

I think most of your suggestions are in use by one or more brigades or SES units.

The busy brigades do tend to roster their crews, partly to be sure of getting out the door, but also to manage fatigue & enforce stand-down times.  Other less busy brigades are merely grateful for every warm body that turns up, & hopefully can scrape up a single crew during b/h or long weekends.

Paging the DO that you are coming is something we implemented at Western Adelaide SES a long time ago. One of the first to do so IIRC.  It works well when your members are widely dispersed & 10-15mins+ is "acceptable" 1st response. That isn't a criticism by the way.... that's a fact of life that metro SES units have to live with & manage due to their demographics. Been there, done that.  Paging your atendance & travel time worked well with commercial paging networks - dial the pager number, instant machine answer, hit 4 buttons on keypad (person ID & ETT in minutes) hang-up & Go. 10, 15, 20 people could do so simultaneously.  It's a waste of valuable oxygen trying that with some Link operators...  :roll: 

Not really an option when your goal is out the door in 4-6 minutes from page. The time taken to lodge a page message chews up too much of that. If you don't have a crew inside 6 minutes, the call defaults (or should, depending upon where the brigade is). Many groups dual or even treble respond brigades to most jobs simply to be sure of a timely response by at least one.

Whatever system used, the response will only be as good as the information provided by the caller.  Fact is callers sometimes lie to ensure that their info is "taken seriously".  By way of example, we have more than once been responded to a local home when the resident has seen smoke some distance away behind some hills - >25km away on one occasion.
Q="where is the fire" A="just across the paddocks"
Q="how far away is it?" A="pretty close"
Q="can you see flames" A="yes, it's pretty big & getting bigger"

The other point is, you have to respond to the risk if the caller/alarm worst case is correct, not to the probability that they are crying "Wolf".  First arriving responder stop-calls the rest if they are not required. Works well provided interservice politics isn't a factor. (I am Stop Call King because I live six (legal) minutes from my brigade.. :lol: )

hope the above makes sense. It's late & I'm tired.

Just kinda wondering why Alan is the king of the stop calls?


G'day Katrina

Dunno about records, but when I get on a truck, some of the older crew start taking off their PPE because they *know* they aren't going to get to the fire... Every now & then we all get a nasty shock & actually have to do something. But I reckon my strike rate is about 5:1 stops.

We canned cadets this evening in order to ensure that we didn't get called.  Figured we could be certain that once every last stitch of hose was off 24, we'd be paged for something urgent...

Am available Thurs & Friday so am fairly confident nothing untoward will happen until Saturday, when I go back on shift.

Wuz gunna say the one in the front left seat, but you've already covered that.

Next most important would be the pump (& water). Without that, may as well take private vehicles to jobs. Just about everything else can be found in someone's car boot or on a roof-rack or shed.

in short a rural CFS ruck carries a no frills first aid kit and that is the limit of items specifically for first aid.

That's about right.
Plus an oversized sharps container & a bio-waste bag.  :roll:
Standard Stowage says "that's all folks".

Some brigades have oxy-vivas dating back to before standard stowage became enforced.
My reading of the standard stowage rools is that, at end-of-life, permission to replace them will be automatically denied for most brigades. (Has yet to be tested in the real world?)

We carry some "vet rope", laughably listed on the stowage check-lists as 'rescue rope'.  I suppose it could be used to un-bog more than one sort of filly. About 20mm double core braid. Soft on the hands. Fits no known rescue or climbing devices. Very cheap. Better than the manilla it replaced, but Bluewater/Edelrid it is -not- !!

G'day Numbers
I reckon once upon a time every brigade had one. 
It was usually brass & about 18 inches long. 
No valve & no handles.  We called it a branch.  :wink:
Had a really nice one at the Queenstown RFB - had a triple-stacked tip.
Solid brass.  Ex-London FB via TFB Hobart if I recall correctly.
With just the first tip attached (1" dia) it delivered water nearly
as fast as our trailer Godiva could supply it. Took 3 strong blokes
to hang onto it. The other 2 tips necked it down to 3/4" & 1/2" for
water economy...

Mostly they were gotten rid of because they were too inflexible - they do just one job superbly well - convert energy from pressure to velocity. I'd suggest most brigades feel/felt that one job occurs so infrequently that it doesn't justify its place on the truck.  Those that still carry them have mostly replaced the stream tips with a variable nozzle. 

We carry a long Fogmaster that has the tapered accelerator built-in. Hasn't been used in anger in the 10 years or so I've been in the brigade.

But there would probably be some brigades for whom a long tapered branch would be useful. Handles & a valve would make it more friendly than the old brass branch.

OFF Topic / Re: Are we a backwater????
« on: March 10, 2008, 12:13:21 AM »
"Backwater" is a highly emotive term used by person/s with an "agenda" - usually to spend other people's money on benefitting themselves.

SA is different to the more populous states.  It has different climate, different geography, different ways of doing things, different population pressures, different building materials. Most importantly, it is located at a different place on the planet & some things must necessarily happen differently.

However....Adelaide has the same lack of water (& breast-beating about lack of fore-thought on water infrastructure), the same pressure groups crying for preservation of some old stuff, or changing of other old stuff.  The whingers use exactly the same phrases to compare Melb/Syd/Bris/Perth with each other & overseas capitals.

The whole argument is therefore built on the falsehood that city "A" should somehow being bigger (more expensive) stuff than city "B".  I think it is a load of bollocks.  If someone really thinks Sydney / Melbourne / Brisbane / etc does things so much better, they should put their feet where their mouth is & move there.

And quit their belly-aching.
