Many plants are green tree species, and some also have the ability to resist air pollution and other adverse environmental factors. For example, Ailanthus altissima has a tall tree crown, lush branches and leaves, and can resist smoke and dust pollution. It is an excellent green tree species for sidewalks, industrial and mining areas, and gardens. The ecological balance and environmental protection functions of landscaping tree species determine their irreplaceable and important "vital organ" position in the construction of modern civilization society. Therefore, whether in terms of maintenance or planting, timely safety protection should be done.
　　
The tall oak tree that used to provide shade and cool for residents is now shaking and dying, causing panic among nearby residents. The day before yesterday afternoon, Changshu Haiyu Fire Brigade dispatched 7 firefighters and finally landed the large tree that had troubled the villagers Shao Xuejun and his family safely after more than 2 hours.
　　
The reporter saw on site in Fudong Village, Haiyu Town that this tree is over 10 meters tall, with a maximum diameter of nearly 50 centimeters at its roots. The surrounding areas of the tree are all residential houses, and large cranes or vehicles cannot approach it. Villager Shao Xuejun introduced that this Chinese toon tree was planted by his father when he was young. At that time, there were two trees planted, and now it has been about 40 years.
　　
In recent years, a Chinese toon tree near the east side has fallen ill and its roots have started to rot, causing the entire tree to wither and die. When encountering strong winds, the whole tree shakes and is about to collapse, which is very dangerous. After receiving the villagers' distress call, Haiyu Fire Brigade quickly rushed to the scene and carried out step-by-step operations under the protection of scaffolding. Finally, they used a chainsaw to cut off the main trunk.
　　
It is worth noting that when using garden machinery chainsaws, the following issues should be noted: pay attention to some logging techniques when using chainsaws to cut wood, which can better and more effectively complete the task. When using a chainsaw, be sure to hold it firmly with both hands and the handle at the back with your right hand. Even left-handed users should do the same. When starting the operation, the throttle of the chainsaw should be turned to the maximum and then the clamp should be tightened; Clamp clamping is very important, otherwise the chainsaw will pull people forward. Always pay attention to the surrounding environment and work calmly and soberly; When working on a slope, users must stand at the top or side of the tree trunk. Pay attention to the rolling of trees and prevent the risk of tripping over tree stumps, branches, and ditches. When sawing trees with fragments, be careful as the wood chips that split apart during sawing can pose a danger; Special attention should be paid to the natural inclination direction of trees, with lush branches. Pay attention to the wind direction and force, and do not cut down trees when the wind is too strong; A distance of 2.5 times the length of the felled trees must be maintained between work to ensure that logging does not endanger the safety of others.
