Which of the following is true about dry chemical extinguishers?

Dry chemical extinguishers are highly versatile fire suppression tools that are particularly effective on flammable liquids. These extinguishers release a fine powder that interrupts the chemical reaction occurring in the fire, effectively suppressing it. The powder works by forming a barrier between the fuel and the oxygen, which is necessary for combustion. This makes dry chemical extinguishers a preferred choice for dealing with classes of fires that involve flammable liquids, such as gasoline, oil, and paints.

While dry chemical extinguishers are also suitable for other types of fires, including those involving electrical equipment (when non-conductive chemicals are used), their ability to quickly and effectively suppress flaming liquids is a key reason why they are commonly found in environments with such hazards.
