Kent - Fog Spike and HV Jet

[Noddy]

Folks,

I am looking at timber framed building fires and have some reading regarding a job in KFRS a couple years ago.  I have read that fog spike was used, as was a 'HV' jet.

I have heard of fog spike but as we don't have it, could somebody tell me in our language what it is exactly please? A for a HV jet, never heard of that one before.  Unless it is a typo, could somebody divulge?

PS.  if you can help but aren't from Kent FRS, feel free to answer too

Cheers

Fog spikes are on all our non cobra appliances. It's a thin metal rod with a simple on off valve and can be attached to hose reel or main jet and produces a fine mist. It comes in "attack" and "restrictor" versions, both carried, which basically Is a choice between a 8m throw with 2m diameter cone or a 3m throw with a 5m diameter cone respectively. Runs at six bar main jet or 20 bar hrj and uses about 70 litres a minute. We use a drill or hammer to make an entry hole and then leave it in situ to bring the temperature down/ create a fire break or just generally control conditions before commiting. 

There was a large line of timber new builds that went up a couple of years ago in Canterbury and they provided a very good fire break. We first used ours on a locked transit with a fire in the rear compartment. Stabbed it through the door until we could gain full access and stopped through whole van becoming involved. I personally think it's a great bit of gear.

I can only assume HV hose reel is referring to the newer large diameter hose reels we have? Not heard the term HV used here. "High volume" maybe?

Many thanks mate.  That's the job I'm reading about.

Having had a demo of cobra from one of the cobra crews during training, they prefer the fog spike overall. We’ve heard nothing about the HV jet though, so not a clue. Only thing I can think of would be jet from a height vehicle, but strange way of putting it.

Not sure much info is out yet, bar what’s in the news, but Holbrough Lakes job in Larkfiekd a couple of weeks back was timber framed and I imagine fog spikes were used during that.

One of these? Ours is for using cafs through for things like cars and skip fires when you have a hidden/smouldering fire.
