NEW 34

[Mike]

The BA system for the cabin of the new 34 appliances consists of 6 'bag' style masks. they are plumbed into a cylinder that lives under the back seat as already mentioned. the newer versions have a shroud around the valve to prevent it from being kicked.

The quick version of how it works:

turn cylinder on, stick 'bag' over head, when situation has passed remove 'bag' from head, turn off cylinder, clean 'bag' using alco-wipes (iso-propanol/medi wipes etc). store in mask holder that hangs on the bar in the middle of the cab.

Must look at ours tonight i don't think ours has got it because we've got stuff stored under our seat????

[Mike]

ours is still to be fitted, but the cylinder frame is already under the seat.....

[backburn]

It was only a week ago ours was put in. They also found out that the bracket was not bolted down either. We have six hoods and each get supplied about 10 mins of air. If you have a heavy breather they get limmited air it does not cut in to your air supply. Well thats the information given to us by the person putting it in. Sounds like we need a shroud on ours.

So does this mean only CABA members can wear / use it?????

me detects sarcasm....

[Alan (Big Al)]

Yep definitly no bracket or anything under our seat must have to be completely installed????

[Toast]

Wow, now they even give us 'exit bags' on the appliance!

[Mike]

Backburn... does your appliance have a HALO system on it?

Im thinking it might only be that build or later rather than all that are getting the 'fresh air system' (or whatever its going to be dubded).....
All speculation though!

[Firefrog]

TIC - Does that mean there will be a flight attendant in your truck "Ladies and gentleman incase of emergency masks will drop from the roof......." :lol: :lol: :wink:

HALON mike. I don't think a High Altitude Low Opening parachute systems gonna be much good in a burn over! :wink: :-D

by HALON, im assuming you are referring to the gas that gets released sucking all oxygen out of the air. Not sure how well they would work in trucks. eh

[Mike]

No.... Not at all.... Definately ment HALO!

The 'Halo' system is a part of the overall crew protection systems on the new 34's. It allows water to be sprayed over the cabin in the event of a flash over. The pump must be running, but it doesnt matter at what pressure as the 'Halo' system is reduced to 80kpa. The valve to operate the system is located just inside the drivers door, and is redily accessable.

Personally we have found that it works a bit better if the pump is working a bit.... ~750Kpa rather than idle.

HALON: Im not sure trying to suffocate the occupants of the cab would be overly useful do you? :roll:

[firetruck]

hahaha fair cop.

I thought you referred to using HALON with those central breathing masks.

but whatever, carry on!

[backburn]

Yes Mike our truck does have the  HALO system on it. Also anyone on the truck can put the hoods on as they are not like the CABA masks. The system maintains your air supply if you have a heavy breather they use all there air not yours. ( well thats what we have been told )

[Alan (Big Al)]

I believe only the first five 34's of last years build came without the Halo system :cry: as we got one of those i guess i better not hold my breath for the air system as well!!! To get the halo put on to an appliance is around the $2500.00 mark i believe....

[rescue5271]

Just take  a caba into the cab and share that,but only for use by those that have CABA...(joke) :roll:

[medevac]

we recently applied to get crew protection sprays put on the cab of our 24P and were knocked back saying that they werent standard...  :roll:

anyway... when we say protection spray, we mean sprays that spray a curtain a small distance from the cab to create a barrier... we have then been told the new system actually just trickles water, so that the cab is kept wet???? now i just want some clarification... is it a spray that creates a barrier or a trickle over the cab/glass...

just wondering, cos the trickle would cause more problems than it solves when it causes all the glass to crack/shatter...

cheers, and i am refering to recently built appliances

[Mike]

The Sprays are directed onto the cabin....

The 'Fresh air system' is very prominantly labeled EMERGENCY AIR SYSTEM.
Surely we can come up with a catchier name than that! sounds to simple to be in the CFS! ;)

[medevac]

The Sprays are directed onto the cabin....

so they spray directly onto the cabin roof and run down the sides? or make a 'curtain around the cabin?

ATTMSYAIAB - air thing that might save your donkey in a burnover

[Mike]

yes...

ATTMSYAIAB - air thing that might save your filtered in a burnover

I like it, but it needs to be something everyone can pronounce easily (even if they dont understand it!)

:-D

[medevac]

that "protection" system sounds like rubbish then... if you heat glassup and then get water on it its gonna crack.... not good.

[Firefrog]

Providing the system is activated prior to flame impact or significant heating the trickling water will keep the glass cool and prevent it failing.

Just in this afternoon...

Is there a problem with the 34???  We are in the same group and also have a new 34, so are we next?

[backburn]

Have seen with a slight wind the sprayed water will miss the glass it blows with the wind, when that stops it goes back on the windows.     :|

So... why do we need a supplementary air system in the ENCLOSED cab of the new 34? Would the money not be better spent retrofitting such a system to those appliances with an open crew deck?
