Every year in America, there are several wildfires happened for American. Sometime we doubt why not pre-caution monitoring the serious cause for protect people’s life and environment from pollution. Therefore, it is the key to fight natural disaster. According to the lastest report from CNN, The fire is more large than last days. Therefore, it makes people thinks a lot.

Harm of forest fire to the environment

During the burning process, forest underground fire will produce a large amount of particulate matter and atmospheric pollutants, which seriously harm the ecological environment and human health.

1. Deterioration of soil physical and chemical properties

Due to the burning of soil organic matter, plant roots, protozoa and microorganisms, the inorganic soil layer is directly exposed to the outside. Under the erosion of rainwater, the soil aggregate structure disintegrates, blocking the soil pores, causing the soil to compact and the soil permeability to decrease. A study on the sandy loam forest in Donglin, Illinois, USA, showed that the soil permeability after the fire was about 1/3 of that before the fire.

After a forest fire, the soil pH value increases, and the increase and duration are generally related to factors such as forest combustibles, forest fire size, soil pH background value and precipitation. In addition, the content of elements such as N, P, K, and Ca in the soil will also change to varying degrees after the fire.

2. Environmental pollution

During the burning process, forest underground fire will produce a large amount of greenhouse gases such as CO2, exacerbating global warming. Fires also release a large number of particles, forming thick haze and causing serious air pollution.

The content of NOX, NH3, CH4, CO and other gases produced by forest underground fires during smoldering is twice that of flame combustion, and a large amount of suspended particulate matter is produced, which will also cause soil erosion, ecological and environmental damage. It is reported that in 1997, underground fires in Indonesia produced a large amount of toxic and harmful gases and smoke, causing severe pollution in Singapore, Malaysia and other places.

3. Ecological damage

A large amount of particulate matter produced during the burning process of forest fires covers the surface of plant leaves, causing damage to the biological metabolism of vegetation and clogging of stomata.

How to monitoring wildfires happened in advance for California wildfires?

In terms of America fire event, there are many problems to consider.

  1. Where are the fire burning?
  2. How many homes have been destroyed?
  3. How many people have died?
  4. Why did so many wildfires break out at about the same time? 
  5. Are the fires expected to keep growing?
  6. How to put out fire in a short time?
  7. How to reduce firefighter life?
  8. How to protect our environment?

However, in China it always happened in the south, as a big nation always we don’t do it better. So, What The USA should do now?

According to this hard problem, our company-Fosensor create a new type of 24h online outdoor environmental monitoring system to get safety alarm in advance when the fire happened.

What kinds of advice offered for Forest fire prevention and control measures?

Since climate and ecological factors have a significant impact on the occurrence of forest fires, the prevention and control of forest underground fires should focus on fire prevention measures for the initial stage of the fire, effective monitoring and accurate positioning, efficient firefighting and post-fire management. 

1.Personnel training

Forest fire fighting requires a large number of firefighters. Relying solely on firefighters from the fire department not only faces the problem of insufficient manpower, but also faces difficulties such as delayed receipt of fire information and inability to arrive at the fire scene in time. The above problems can be effectively alleviated by organizing residents around forest fire sites to form civilian volunteer fire brigades.

2.Water source marking

For areas prone to fire, detailed mapping of surface water and groundwater sources in the area should be carried out and prominent markings should be made on maps and on the ground to ensure that when a fire occurs, rescue workers can quickly obtain water from the water source for firefighting activities.

3 Forest land maintenance

Under climatic conditions of high temperature and little rainfall, forest areas can replenish soil moisture through methods such as aerial watering, surface spraying, and artificial flushing to maintain the soil moisture content at a high level, keep the ground moist, and thus reduce the chance of underground fires. In addition, since underground forest fires are mostly caused by surface fires, the heat is transferred underground, causing the underground fire to spread. Therefore, professional forest clearing personnel are organized to regularly clear dead trees and branches, dwarf shrubs, accumulated fallen leaves, humus, etc. that are prone to cause surface fires. , is also an effective way to prevent underground fires.

4 Fire Monitoring

Conduct a comprehensive investigation of forest geological, hydrological, meteorological and other factors, collect records of forest underground fires over the years, and count the time periods and areas with high incidence of underground fires. Utilize meteorological factors for early warning, make a preliminary assessment of the probability of underground fires, organize personnel to focus on prevention, and build an “air-ground-underground” multiple monitoring system.

4.1 Aerial monitoring

 Using highly sensitive satellite sensing to monitor:

4.2 Ground monitoring

Using portable infrared temperature measuring equipment to monitor

Monitoring using gas detection equipment: In some dense woodlands, due to the obstruction of tree branches and leaves, the method of relying solely on temperature detection to judge underground fire conditions faces problems such as inaccurate fire detection and delayed fire transmission. Since the burning of underground fires will release a large amount of gas, it is possible to determine whether a forest underground fire has occurred by detecting the gas composition. Use online or handheld gas detection equipment to detect the content of underground fire indicator gases such as nitrogen oxides, ammonia, CO and organic particles. When the content of the indicator gas reaches the critical value of fire risk, it is necessary to be alert to the occurrence of underground fire and take appropriate measures. Be prepared to fight underground fires. For areas where underground fires have already occurred, gas detection equipment can be used to preliminarily determine the spread of underground fires and the boundaries of the fire scene, providing reliable fire information for subsequent underground fire fighting and post-fire supervision.

4.3 Fire Fighting

The isolation method is to destroy the continuity of underground combustible materials through mechanical, manpower and other means, thereby cutting off the spread of underground fire and effectively controlling the development of underground fire. The partition method mainly uses pickaxes, shovels, axes, rakes, trenchers, etc. to carry out direct and indirect beating.5.Post-fire management

1) Plant fire-resistant tree species. By planting tree species with poor flammability and strong fire resistance, a biological fire prevention forest belt can be formed, thereby reducing the probability and spread of forest fires.

2) Promote ecological restoration. Ecological restoration can be promoted by introducing seedlings with artificial assistance and maintaining the growth environment of the seedlings.psum dolor sit amet, consectetur adipiscing elit.
