Scuba Cylinder kills fire fighter

[Rollin Bonz]

What is the typical pressure in a cylinder used for firefighting? 3000 psi seems like overkill for surface breathing, maybe scuba tanks are more pressurized than the ones they were used to working with?

Compressed gas has huge amount of energy stored into it.
We need to respect that ....

@fsardone can you give us more information about the different tanks shown in the video? The last 2 tanks were obviously less reactive to the loss of the valve, were they at lower pressures?

Firefighters can have dive teams too

oh yeah...

Says it right in the report.... never mind

Not a German or (decent) French speaker but the video shows the advantage of built in orifice restrictor for the tanks. So with such a device we might have had a survivor rather than a victim ...

3000 PSI are old packs. 4500 PSI are the next generation and 5500 PSI are now the standard. At least in the US. I don't know about European firefighting.

That's what they are filled to for use?

Small tanks long time .... fighting a fire. 300 bar is quite common ...

That is why I said PSI... Yes - 5500 PSI are the packs being sold to be compliant with the NFPA.

Yeah I have zero knowledge of the equipment needs for firefighters anywhere to be honest. For some reason I always assumed pressures were less in their tanks.

Googling it for you. Then we should stop since this is A&I and this has little to do with the accident except is even higher pressure than a scuba tank ...
