# A flaming fuse box should be sprayed with what type of fire extinguisher?

Mind you, when the $hit hits the fan, and you are actually required to use an extinguisher in earnest you are very unlikely to read the chart properly beforehand. I have seen a few still fires (containing sodium and amalgam) put out with a $C {O}_{2}\$ extinguisher (for which use it is contraindicated). And if it is a bigger fire, often the physical heat of the flame prevents you from approaching it.
