Methods for extinguishing a fire caused by magnesium powder

How should a fire caused by magnesium powder be extinguished? Can a dry powder fire extinguisher be used? Thank you?
Just search on Baidu! Dry powder isolates air
First of all, it should be known that both magnesium and sodium are reactive metals that can react with water; therefore, water cannot be used to extinguish fires involving them. Nor can carbon dioxide fire extinguishers be used, as magnesium also reacts with carbon dioxide. Dry powder fire extinguishers contain sodium bicarbonate, which produces carbon dioxide, and magnesium powder can still burn in the presence of carbon dioxide. In some cases, dry sand can be used to put out such fires
It is advisable to use sand to extinguish the fire. Dry powder fire extinguishers are generally suitable for extinguishing Class A, B, and C fires; they are not effective for metal fires.
It definitely won’t work. It’s not that it can’t be used, but the pressure from the dry powder will scatter the magnesium powder, causing an even bigger fire!
Dry powder fire extinguishers cannot be used for metal fires; they are not suitable for such situations.
There are generally no effective methods for extinguishing Class D fires; sand is usually used to cover them
