However, you generally shouldn’t waste time finding a damp rag in an emergency: it’s also dangerous to use a tap to wet a damp rag depending on the severity of the fire,(24)as if the water pipes in your home are exposed to high temperatures, the water traveling through them may be converted to steam which will blast out of the pipe and cause burns.
