Open Face, Piss Pot (safe?)

[gtfire]

On the other hand, a piss pot does not need removing for someone to give you mouth to mouth resuscitation or for the ambulance guys to use an O2 mask on you meaning potentially less neck injuries.

Personally, I wear a flip front most of the time so have the best of both. Full face protection but easy access should it be needed.

BTW, I know that the current method of CPR does not include mouth to mouth (just chest compressions) but not everyone does!

In every incident I have been to all Helmets have been removed at a very early stage. There is a clear process to removing the helmet be it an open faced or not. Some Ambulance staff are a little reluctant at the very early stages but it soon becomes clear that in nearly all cases it's the only way you can stabilise a casualty for transportation.
But a flip lid or open face does allow fast access to airways but that lid would be off very quick if CPR was required.
