The firemen in question are from the Havelte volunteer brigade in the Netherlands, and their story is that they were waiting for the gas company to come and shut off supply when they were snapped by a news photographer who was present, who then cheerfully put the picture on his site here.
That's where you can see how the fire turned out. As you might predict, but clearly the blokes in the picture didn't, the house burned to ashes. All part of the service, ma'am.
