IPC: A62D1/00
Filed: 2016-10-29
Abstract: PROBLEM TO BE SOLVED: To solve a problem that a deluge system using fire extinguishing water has to spray the fire extinguishing water continually for spreading fire prevention because the fire extinguishing water flows out from plant roofs such as thatched roofs in and after spraying, and has to prepare for a large quantity of the fire extinguishing water.SOLUTION: Spreading fire is prevented and fire is extinguished by spraying spreading fire prevention agent which is an agent with high viscosity instead of fire extinguishing water and applying it to plant roofs. Spraying amount can be reduced because the agent with high viscosity sprayed to the plant roofs to prevent spreading fire and to extinguish fire remain in the place. The spreading fire prevention agent has viscosity to remain in the plant roofs and comprises thixotropy with specified viscosity to reduce pressure drop in pipings and hoses in spraying.SELECTED DRAWING: Figure 1
