Which type of fire extinguisher is designed to put out class A fires?

The type of fire extinguisher specifically designed to tackle Class A fires is a water can extinguisher. Class A fires involve ordinary combustible materials such as wood, paper, and textiles. Water extinguishers work by cooling the burning material below its ignition point, which effectively extinguishes the fire.

Using water is a straightforward and effective method for these types of fires since it can absorb heat and disrupt the combustion process. Other options such as CO2, dry powder, and dry chemical extinguishers are designed for different types of fires. For instance, CO2 is effective for Class B (liquid) and Class C (electrical) fires, while dry powder and dry chemical extinguishers are versatile but more suited for multiple classes, including Class B and Class C, rather than Class A specifically. Thus, the water can is the appropriate choice for combating Class A fires.
