Fire Classes

Class A: Involves fires from common combustibles such as wood, paper, rags, rubber, and plastics.
Class B: Comprised of fires from flammable liquids, including grease, gasoline, oil, and paint thinners.
Class C: Pertains to fires caused by electrical equipment, like appliances, motors, and wiring.
Class D: Associated with combustible metals, particularly used in industrial settings with materials like magnesium and aluminum.
Class K: Relates to fires originating from cooking media, primarily vegetable oils and animal fats.

Fire Extinguishers

Class A fire extinguisher: Specifically designed for Class A fires; utilizes a water-based solution for effective suppression.
Class B fire extinguisher: Employs dry chemical powder to combat Class B fires, effective against gasoline, oils, and solvents; versatile for multiple fire classes.
Class C fire extinguisher: Uses gas-producing liquids to tackle Class B and C fires; inappropriate for Class A (risk of spreading) or Class D (explosion hazard).
Class D fire extinguisher: Contains dry powder specifically for extinguishing fires from combustible metals; critical in factories and industrial environments.
Class K fire extinguisher: Employs a low pH, potassium acetate-based agent; essential for extinguishing Class K cooking fires, providing safe and efficient suppression.
