Australian bushfires, how to extinguish them in the event of a bushfire?

Authorities deployed more than 500 firefighters to fight the fires in southern Australia, which had been raging for several days, forcing thousands of people to evacuate their homes. The Meteorological Department pointed out that the recent drop in temperature in the hill fire area has helped firefighting work. Australian authorities said that the wave of fires began on January 2 local time, due to the high temperature and strong winds, the fire is fierce, more than a dozen homes have been burned on the hills of Aredre, and more than 20 more may not be protected.

There are also bushfires in neighboring Victoria, but the local rains have brought the fires under control, and many people who have been evacuated by the fires can return to their homes on the 4th. The town of Mowei has been enveloped in smoke, and authorities say it could take months to extinguish the fire. Tens of thousands of local residents are at risk of health due to smoke inhalation, and authorities are urging vulnerable groups to evacuate the area.

Although authorities said that the smoke from the wildfires did not pose a health risk to the population, thousands of masks were distributed to local residents.

Australian Prime Minister Tony Abbott went to the disaster area to learn about the disaster, praised the firefighters who are fighting on the front line of the fire, and expressed condolences to the victims who were injured and suffered losses due to the fire. "Natural disasters in Australia are frequent, and we are worried and saddened when someone encounters danger and difficulty, while being proud of the thousands of firefighters and volunteers who have fought the fire and protected the people," Abbott said. At present, the Australian authorities have dispatched more than 500 firefighters to extinguish the fire, and many firefighters have also been choked by smoke due to firefighting.

Bushfires occur every summer in Australia, and in 2009 more than 2,000 homes were destroyed and 173 people were killed.

Smoke billows from the town of Sampson in the Adelaide Hills region of South Australia, Australia, on January 2. Bushfires broke out in Victoria and South Australia in Australia since January 2, and due to strong winds, fires in many places remained uncontrolled as of the 3rd, and are expected to continue until next week. Dozens of homes have been destroyed as a result of the wildfires, but no people have been reported.

Forest fires are often more serious in remote areas where provinces, counties and communities are contiguous, so in the contiguous areas, the administrative areas should be used as a unit to establish and improve forest protection and joint defense organizations through joint consultation, and implement the relevant forest protection and fire prevention policies; research and deployment of forest protection and joint defense work in adjacent areas; summarize and exchange experience in forest protection and fire prevention; commend advanced units and individuals; Organize and extinguish forest fires.

What drives forests to burn is still the three elements of combustion – oxygen, temperature and fuel. However, in vast spaces, where air is ubiquitous, it is difficult to extinguish fires by means of closure and suffocation. Therefore, in response to forest fires, firefighters need a very different strategy than building fires, and isolating the fuel needed for wildfires is one of the main ways to fight wildfires.

Usually, firefighters will select an area according to the direction of the wind, the size of the fire and the situation of the trees at the time of the fire, cut down the tall trees in it, and remove the shrubs and most of the leaf litter from the ground to build a separation zoneWhen the fire line spreads to this point, it will be reduced and divided due to the lack of fuel, and at this time, the firefighters can extinguish the open flames that are surrounded by divisions.

2020 is a year that makes many people want to "restart". Throughout the month of January, the most we heard was some unpleasant news. The first of these is probably a bushfire in Australia.

Bushfires in Australia have been burning since July last year. As we have already mentioned, bushfires are a regular occurrence in Australia, especially this year. The smoke-shrouded forests of Australia have touched the hearts of people all over the world, and have also brought many undesirable situations to Australia.

On February 12, the Australian bushfires, which had lasted for about half a year, finally ended. Statistics show that the fire lasted a full 210 days and burned 400 hectares of forest. In addition, 11.7 million hectares of land were burned, an area larger than Jiangsu Province and almost the size of seven Beijings.

It was extinguished on February 12.

In early January 2020, bushfires in south-east NSW and eastern Victoria developed dramatically. According to the fire monitoring map of the Fengyun-3 meteorological satellite on January 4, a large number of fire points were distributed in an area of 270 kilometers from east to west and 360 kilometers from north to south, and some fire areas have spread to the vicinity of the beach, with a total area of about 7,900 square kilometers. Most of these fires occur in forested areas.

Australia has few forest resources, mainly distributed in the eastern, southern and northern coastal strips, and in the past, wildfires mostly occurred in inland grasslands, wastelands and savannas, and forest fires were relatively rare. Serious fires broke out in many forests, burning large areas of woodland, causing a large number of deaths of rare animals such as koalas that inhabit the forest, and having a catastrophic impact on the local ecological environment.

Smoke from wildfires also has a serious impact on air quality. According to the Fengyun-3 meteorological satellite on January 5, a large area of smoke caused by the wildfires in eastern Australia has drifted to northern New Zealand, and the smoke has traveled about 2,000 kilometers, affecting the local air quality. The latest monitoring on January 7 showed that significant smog information could still be seen about 6,000 kilometres off Australia's east coast.

Australia's wildfires have been raging for months, and by early January 2020, the wildfires had spread to more than 10 million hectares and killed 28 people. In New South Wales, Australia, 500 million animals, including 20,000 koalas, have been burned to the sea, and the total number of animals killed by the wildfires in Australia has exceeded 1 billion, and many species are on the verge of extinction.
