Dry powder extinguishers are fire safety devices designed to combat various types of fires, including those involving flammable liquids and electrical equipment. They contain a dry chemical powder, typically monoammonium phosphate, which works by smothering the fire and interrupting the chemical reaction that sustains it. These extinguishers are versatile and can be used on Class A, Class B, and Class C fires. These extinguishers are easy to use and are often found in homes, offices, and industrial settings. They are marked with a color-coded label to indicate their suitability for different fire types. Regular maintenance and inspections are essential to ensure they function properly when needed.
