portable wet chemical fire extinguisher  

A portable wet chemical fire extinguisher is a small, lightweight fire-fighting device that uses wet chemicals to extinguish fires. Wet chemicals are special chemicals that form a protective film that isolates oxygen from burning materials, effectively inhibiting the spread of fire. This type of fire extinguisher usually consists of a pressure tank and a nozzle. When a fire breaks out, users simply point the nozzle at the fire source, press a button on the fire extinguisher or pull the safety pin to release the wet chemical. The wet chemical spray comes out as a spray and quickly covers the fire source, forming a protective film and extinguishing the fire.Wet Chemical Extinguishing Agent
