A fire extinguisher is a portable device used to put out or control small fires in emergency situations. Fire extinguishers work by discharging a substance that suppresses the fire, interrupting the chemical reaction that sustains the fire.

An ABC type fire extinguisher is a versatile, multipurpose extinguisher that can handle fires in three different classes:

• Class A: Ordinary combustibles like wood, paper, cloth, and plastics.
• Class B: Flammable liquids such as gasoline, oils, and solvents.
• Class C: Electrical fires involving energized electrical equipment (wiring, computers, appliances).

ABC fire extinguishers typically use a dry chemical powder, often ammonium phosphate, that works by interrupting the chemical reaction of the fire. It’s effective on most common fires, which makes it a popular choice for both homes and businesses.

Because it's a dry chemical, you should be cautious when using it near sensitive electronics, as the powder can be abrasive and could cause damage if it gets inside devices. Also, since it can make a mess, it’s recommended to only use it if the fire is large enough to require it.
