What type of fire extinguisher is referred to as "ABC"?

1. Water-based extinguisher

2. Multi-purpose fire extinguisher

3. Foam extinguisher

4. DCP extinguisher

The correct answer is: Multi-purpose fire extinguisher

The designation "ABC" for a fire extinguisher indicates that it is a multi-purpose fire extinguisher, which is capable of effectively combating fires fueled by three different classes of materials. Specifically, it is suitable for Class A fires (ordinary combustibles like wood, paper, and textiles), Class B fires (flammable liquids such as gasoline, oil, and grease), and Class C fires (electrical equipment). This versatility makes the ABC extinguisher a valuable tool in various environments, especially where different types of fire hazards might be present, such as in homes, offices, and healthcare facilities. Its ability to tackle multiple fire types reduces the need for multiple different extinguishers, simplifying safety preparations and responses in emergency situations. In contrast, water-based extinguishers are only effective for Class A fires, foam extinguishers are specifically suitable for Class B fires and a limited range of Class A fires without addressing electrical or flammable gas fires, while DCP (Dry Chemical Powder) extinguishers can cover some of the same classes but are not generally referred to as "ABC" unless they have that specific versatility. Thus, identifying a fire extinguisher as an "ABC" type clearly communicates its use for a broader range
