Doesn't the tank vent underneath, rather than burning your hand? I'm 90% certain it's just forcing a bit of coolant out of the vent when you loosen the cap. Are you doing it with the engine completely cold? It surprises me that there would be any pressure at all in the system, with a cold engine...
