These fires involve:

Class C: Flammable gases.
The extinguisher uses mono-ammonium phosphate powder, which quickly knocks down flames. It is also safe for use on electrical fires up to 1000V, but can cause contamination and corrosion if not cleaned properly.
This type of extinguisher is suitable for various settings, including homes, commercial and industrial spaces, and vehicles. It's particularly useful in outdoor areas and can withstand low temperatures. However, it's not recommended for use in escape routes due to visibility reduction caused by the powder.
