Baking soda puts out fires by releasing carbon dioxide and smothering the fire , but if your fire is burning violently enough, the convection created by the fire pulls in enough oxygen to offset the smothering effect. Then, in the case of a fire that is defined as electrical, water is useless and in fact only encourages the decomposition of the lithium which gives way to a more violent combustion. That's where we completely extinguish any combustion mixture, that there's no combustion that needs to happen, no manual firefighting, just a little investigation.
