The water-based fire extinguishing agent is a fire extinguishing agent taking water as a solvent, can play a role in cooling and isolating oxygen on the surface of a comburent, can also play a role in blocking a combustion chain, eliminates smoke, insulates heat, can extinguish A, B, C, E-type fires, has a wide fire extinguishing spectrum, and can be used for a fire truck and a fire extinguisher. Fire extinguishers filled with water-based extinguishing agents (containing foam), known as water extinguishers, require foam nozzles for foam generation and water (usually flood) nozzles for non-foam generation. Since fire extinguishers are prepared at various fire points, fire extinguishers are generally the first fire extinguisher to be used in the face of some sudden fire.
