A water fire extinguisher is designed to suppress and extinguish Class A fires, which involve solid materials like paper, wood, and textiles. When activated, it sprays water at high pressure, smothering the flames and lowering the temperature of the burning material. Water fire extinguishers are safe to use around children, vulnerable adults, and food, as they don’t contain harmful chemicals. However, do not use them for electrical fires, flammable liquids, or flammable gases. They’re commonly found in environments like warehouses, storage units, and textile factories. Available sizes include 3, 6, and 9 liters
