How big is an "F"

Hi guys,

Thanks

An F is actually a V when filled with Helium.

BOC Balloon Gas - Helium Balloon Gas

Confusing no ?

Not a user of helium in diving, but has anyone actually tested the purity of baloon gas versus medical/diving grade helium?

Yes. No good for diving. Lots of other random gases possibly in there, including potentially CO2 and CO. Neither of which you want near you underwater. At all. It's not a controlled gas in the same way as O2 and He for breathing use are. But it doesn't stop a lot of us using welding O2 when needs must.

Plus it's bloody expensive against the cost of industrial gases in a lot of cases.

Digs.
