Sort of like how a transformer explosion is typically a lot worse due to the oil used to cool larger transformers. The oil is great because it allows for heat transfer well, fits into all the nooks and crannies and isn't conductive to electricity. But, the oil is still flammable. And then, trying to put out the flames, the combination of electricity and oil makes using water a very bad idea.
