Thank God all turned out well SNICKO!
Well dome to all of those who acted so rationally.
Can I please say now to all who read this, that if this happens to you, remember if a gas hose burns, gas continues to escape fromt the bottle and burn (as stated here). If you keep the bottle cool with water(as the fireman did) and allow the gas to burn out, you will remove the risk of explosion.
Bottles explode when the heat expands the gas in a bottle at a greater speed than it can escape and burn.
In saying all this, it hard to beleive keeping a bottle cool with water is safe, when life teaches us that gas bottles explode.
You did all the right things Snicko.
