EEBD & Nitrogen question

[dannie58]

Will this EEBD hood fit directly on to this regulator/flowmeter?

This looks good

What is the measurement unit in that flowmeter, lpm or cfm?

Eebd hood is not like scba kit where you need high pressure

You can use the below hose clip to make the hose hold tight to the regulator and just make sure there are no leaks using soap water (there are different types of hose clips)

This is my set up too. I'm planning on covering the windows in my car, buckling myself in with the tank in the passenger seat and ctb in the parking lot at night. Going to send a scheduled email to a friend so emt will be called. Don't want to traumatize anyone.

I don't have enough gas to test the set up so any advice on how to make sure this works is appreciated.

You need gas and oxygen analyzer to test it

It's CFM but is adjustable. Should I be using a different type of flowmeter with EEBD or will this work?

This is okay but you have to do calculations to convert lpm to Cfm which I don't know, try to find a regulator with lpm if you can't find go on with this

I was concerned because this EEBD was not made in the US and the hose is black. Most hoses I see with EEBD are blue.

This is a drager eebd hood which is a good quality just make sure you connect without any leaks

With using an EEBD, how much nitrogen would I need? I thought with EEBD you can get away with a pretty small amount of nitrogen?

15 LPM is the recommendation--Thats what I used with my tests, and my oxygen level fell off a cliff

 

[anonaon]

No, thats for SCBA I'm pretty sure. Both EEBD & exit bag setup need to run for between 5-15 mins at 15LPM minimum. It is recommended that you go no less than 600L for extra saftey margin

I would go with 1000L or 40cft tank because you will lose some gas during testing, for eebd hood recommended ppeh gas flow is 25 lpm

15, 25 doesn't matter, either one, Greenberg says 15 LPM is fine for the hood--25 might bother some because its louder--have you done any tests with the oximeter with the hood on yet?

I am not testing on me, I am waiting for oxygen detector to test it

Yes during Greenberg days ppeh they recommended 15 lpm but recent ppeh they recommend approximately 25 lpm for eebd hood but exit bag is still 15 lpm

But you are using ear plugs anyway

Ok maybe I'll do 25 LPM then--Thx

Please let me know how the oxygen detector test works out when you get it and use it to test

Yes I will

I am gonna put eebd hood over a mannequin switch on the nitrogen gas, put the oxygen detector inside the eebd and measure, if oxygen level go like 1% then it works

 

[outrider567]

Yes I will

That's for sure!

I don't see a follow-up on this. Your EEBD guide suggests a minimum of 15 Lpm. Did you find this to be sufficient in your testing? I am trying to determine what size tank I need.

He's not gonna be able to reply, he CTB'd.

15Lpm is plenty. @outrider567 has done plenty tests with 15Lpm and it works as intended. 600L uncompressed is the minimum volume recommended here. You can go lower but it's good to have some extra slack

Well yes, it works well as far as it goes, but I'm still here--I thought GasMonkey suggested 25 LPM for the EEBD Hood now, Das Nichts used 25 and he passed out, life only saved because he fell down and hit a cabinet and dislodged the flow, so I'm not sure what rate I'll use now

I think 25 LPM is recommended for the 3M hoods that don't have an exhalation valve. K, the owner of escmode, says that 15LPM or higher is viable.

Ok thx, that's what I thought

Yeah, and GasMonkey just said that a recent successful CTB individual with the Hood used 15 LPM, with a 580 Liter tank

Is 5 liter tank enough it's 200 bar

 

[anonaon]

Dude you've asked this question like 10 times. Yes, its enough. 5L×200bar= 1000L of nitrogen. 1000L/15LPM = 66min of contnious flow. More than an hour. You die in 3-10 mins. Its more than enough.

Vizzy used at least twice as big that's why I am weary.. sorry and I am not a dude, wish I was then I would maybe be more technical..

Well rest assured both your 2L & 5L cylinders are viable

Are there goodbye threads an affirmed ctb s here with 5 liters? I know Pph says 2 but don't really trust that

Not that I know of but people have successfully CTB'd using Ballon time helium tanks for decades (note - these are filled with 20% air so its not longer viable) which carry only 250L of helium. Your 2L cylinder carries 400L and your 5L cylinder carries 1000L or 4x that amount.
