If you remember from fire extinguisher training, there are three classes of fires. Class A is ordinary combustibles (paper, wood, etc.). Class B is grease/oil/etc. Class C is electrical. You can use water to extinguish a Class A fire, but it would actually make things worse for Class B and Class C fires. For Class B, because oil and water don't mix, it would just spread the burning oil around. And for Class C, water + electricity is obviously a bad idea. This is all really basic. I learned it in babysitting class when I was 12, and I'm sure you all learned it similarly early on.
Conventional wisdom is that installing sprinklers makes it much safer if there's a fire. Question: what happens if it's a grease fire or an electrical fire?
