I.Introduction
Environmental forest fire extinguishing agent is a kind of water series extinguishing agent,put fire extinguishing agent powder into water with specific proportion,it will form the sticky liquid with good flame-retardant.This sticky liquid will form the cover layer on combustible to cut off the contact with air and cool surface temperature to put out the fire and prevent reburn.The agent has no toxic、no taste、environmental.It will save 80～90％ water which will realize the high improve of water extinguishing efficiency.
II.Features
Efficient—stick on the combustible 5 times more than water and 6 times flame retardant function better when put out fire.
Environmental—forest fire extinguishing agent has no toxic and taste,no stimulation to fireman’s skin and breath.The rest agent after fire not only has no pollution to environment,but also keep soil moisture;No corrosion to metal part of spray device.
Water saving—forest fire extinguishing agent water absorption rate can be hundreds times of water,which can improve the water utilization to put out the fire quickly with less water.
Low cost—compared with chemical extinguishing agent,the additive proportion in water is almost 1/30 time of chemical extinguishing agent.It can be put in fire truck、fire pump and water-based fire extinguisher without any change,which will save a lot.
III.Extinguishing method and equipment
Environmental forest fire extinguishing agent can be sprayed out to extinguish the fire by different equipment,such as fire fighting plan、fire truck、hand lift fire pump、portable forest fire extinguishing machine and water based fire extinguisher.Among them,there is no need to change the present equipment structure like fire truck、hand carrying fire pump and fire extinguisher.
There are two methods for extinguishing agent to put out the fire:The first one is spray out directly to extinguish the fire.Firefighters use the extinguishing equipment with prepared polymeric hydrogel extinguishing agent to spray on the combustible.This way can be used to put out small and medium forest fire;The second is put out the fire indirectly.Spray out to the wind direction of forest fire by plan or other spray equipment,generate the flame retardant median by forming the hydrogel layer to control the fire.It can be applied in big and fast spread fire,which firefighters are not able to put out the fire directly.It will highly improve the extinguishing efficiency with above two extinguishing methods.
IV.Application
The product can be used to put out A class fire especially forest、grass and national park and scenic area.
