In general what are dry chemical fire extinguishers designated to do?
Fire needs three things to burn: fuel, oxygen, and heat. Take away one or more of those three things in sufficient quantities, and the fire can no longer burn.
.
A dry chemical fire extinguisher sprays a noncombustible, air resistant layer of foam designed to cover the fire's fuel source. When the fuel source (wood, oil, cloth, etc.) is completely and properly smothered, the expelled dry chemical foam isolates the fuel from the surrounding air, and thereby starves the fire of the oxygen it needs to burn.
What is meaning of black fire extinguiser?

Others are green (halon gas) or yellow (foam) or red (water)
- usage depends on type of fire

Realistically, i don'tknow of any.
Magnesium metal burns in the presence of CO2 (undergoes what's called
an oxidation-reduction reaction, the Mg is oxidized to MgO and the carbon
is reduced to solid carbon). This can be readily seen by burning Mg in
dry ice. Trying to use a CO2 extinguisher on burning Mg simply causes it
to burn more. This happened to a British ship during its war over the
Falkland Islands. They tried to put out a fire in the hull after it was hit
using CO2 extinguishers and it simply caused it to keep burning. I would
bet there are other metals that will also react with CO2.
Which fire extinguisher supplier does a firestation use?
There are two main types of fire extinguishers: stored pressure and cartridge-operated. In stored pressure units, the expellant is stored in the same chamber as the firefighting agent itself. Depending on the agent used, different propellants are used. With dry chemical extinguishers, nitrogen is typically used; water and foam extinguishers typically use air. Stored pressure fire extinguishers are the most common type
