It is safe and environmentally friendly, uses water as the fire extinguishing agent, and has dual fire extinguishing mechanisms such as efficient cooling and asphyxiation. It is harmless to the human body and has no impact on the environment. It will not decom-pose and produce harmful substances at high temperatures. While spraying, it does not cause any harm to people in the spraying area, which is beneficial to the escape and firefighting of on-site personnel. The water consumption is 1% of water spraying, which greatly reduces the volume of the fire water tank (pool) and avoids secondary disasters caused by large amounts of drainage.
