Class B fire extinguishers are best suited for fires involving flammable liquids, such as gasoline, oil, grease, and solvents. These extinguishers typically use foam, dry chemical, or carbon dioxide agents to effectively smother and extinguish the flames. They should not be used on fires involving ordinary combustibles (Class A) or electrical equipment (Class C) unless specifically rated for those classes as well. Always check the extinguisher label for specific applications.
Fire extinguishers are best used on incipient (at the beginning) fires.
Liquid (oil) fires.
The best extinguisher for a Class A fire, which involves ordinary combustible materials like wood, paper, and cloth, is a water extinguisher or a foam extinguisher. Water extinguishers work by cooling the burning material, while foam extinguishers can smother the flames and create a barrier to prevent re-ignition. It's important to avoid using water on Class B or electrical fires, as this can worsen the situation. Always ensure the extinguisher is rated for Class A fires before use.
Because there are so many possible different kinds of fires in a home you are best to get an extinguisher with at least an ABC class rating. These ratings are for different types of fires.
Ordinary combustibles, such as wood, cloth, paper, burning liquids such as gasoline, and fires in live electrical equipment. They are not for deep fat fryers (class K) nor for combustible metals such as magnesium (Class D fire).
Call A fire extinguishers are normally the best type for taking out fires, and keeping your family safe. It is advised to have at least one in any store and possible even your house.
Burning liquids such as gasoline, oil, paint, etc.
How big of a fire is it? If it's a small fire, like a trash can or something, airliners have handheld fire extinguishers. For an engine fire or a cargo compartment fire, airliners have fixed fire suppression systems--the plane has plumbing, sprinkler heads and tanks of fire extinguishing agent. But those huge fires you see when a plane crashes? Aircraft crash fires are primarily fuel fires--Class B. The best agent is Aqueous Film Forming Foam, or AFFF, which was invented by the US Navy to fight fires on aircraft carriers. It works extremely well.
