Only a Class D fire extinguisher should be used on fires involving combustible metals, such as magnesium. It will smother them by denying access to oxygen.
a dry powedr extinguisher
Combustible metals like aluminum or magnesium
Because Magnesium, like other highly reactive metals, is much more easily oxidized than most fuels for fires. The Magnesium can essentially "steal" oxygen from the carbon dioxide CO2 + 2Mg --> 2MgO + C
Combustible metals like Aluminum, Magnesium, Lithium, Sodium, Copper, Ext.
A foam extinguisher is stored like any other extinguisher that contains liquid that might freeze.
Usually, Alloys have better properties - like strength-to -weight ratio - than the parent metals. Pure Magnesium is also a bit nasty to use and work with as it can Catch fire.
These metals are very different.
they are alkali earth metals.
It depends upon the type of chemical that is burning, but frequently it is safe to use a dry-chemical powder (DCP), or an ABC type of extinguisher. However, boiling grease fires may need a Class K extinguisher and flammable metals (aluminum, magnesium, lithium, etc) may need a Class D extinguisher.
He was a black inventor who invented the fire extinguisher.
Class A extinguishers are designed for "ordinary flammable materials" (organic solids such as paper and wood) but not liquids like gasoline, grease, electrical fires, or flammable metals.
Like any other fire, a burning candle requires fuel, heat, oxygen and a chemical reaction. If you use a fire extinguisher, it typically removes the heat or oxygen from the process, thus stopping the fire.
Multi-purpose fire extinguishers, like ABC, are typically dry chemical.
