It does this because it is a completely, 100% oxidized material.
This smothers the fire..
Can water help fire?
Water can actually do three things with fire: Feed it, not affect it, or quench it, depending on the fuel. For burning solids, such as paper, wood, or coal, water will extinguish the fire by two methods: cooling and, if enough is present, depriving the fire of oxygen. A fire needs three things: heat, fuel, and oxygen.

How does spraying water on a fire help to put the fire out?
Why does spraying water on a fire help to put the fire out? Water covers the fuel, which keeps it from coming into contact with oxygen. In addition, the evaporation of water uses a large amount of heat, causing the fire to cool. … Steel is exposed to water and salt rusts quickly.
