The most versatile extinguisher is generally theABC powder extinguisher. Here's why:
Fire Class versatility: The powder extinguisher is effective on Class A fires (dry or braising fires: solid materials such as wood and paper), Class B (greasy, liquid or liquefiable solid fires: hydrocarbons, alcohol, solvents, greases, oils, paints...) and Class C (flammable gases such as propane and butane). This makes it a versatile choice for a variety of fire situations.
Varied applications: It is widely used in garages, workshops, warehouses and industrial environments where various types of fire can occur.
Durability: Powder extinguishers often have a long shelf life and are less sensitive to temperature fluctuations than other types of extinguisher.
However, it's important to note that powder extinguishers leave powder residues after use, which may require more thorough cleaning than other types of extinguisher such as foam or CO2. For this reason, the choice of the most suitable extinguisher will also depend on the specifics of the environment where it will be used and cleaning preferences.
