Final answer:
A water type fire extinguisher uses water as the primary extinguishing agent to cool down and extinguish fires involving solid materials.
Step-by-step explanation:
A water type fire extinguisher is an extinguisher that uses water as the primary extinguishing agent. It is designed to extinguish fires that involve solid materials such as wood, paper, and textiles. When water is applied to a fire, it cools down the burning material and reduces the temperature below its ignition point, effectively extinguishing the fire.
This type of fire extinguisher works by discharging a jet or spray of water onto the fire. The water absorbs heat from the fire, lowering its temperature. It also helps to remove combustible materials from the fire, preventing it from spreading.
Water type fire extinguishers are commonly used in residential, commercial, and industrial settings. However, they are not suitable for fires involving flammable liquids or electrical equipment, as water can conduct electricity and may cause electrocution.
