Class report room

Strong winds will blow down high-altitude objects, which will easily lead to pedestrian casualties. Therefore, before the typhoon comes, it is necessary to fix the flowerpots, outdoor air conditioners, awnings and scattered items on the construction site. And don't forget to move the sundries in the window frame indoors to ensure safety. Check whether the doors and windows are closed tightly, nail the loose doors and windows firmly, and if possible, add a horizontal bolt behind the doors and windows. Open air or balcony with poor sealing performance, especially to prevent rainwater from flowing backwards. In addition, don't move around the windward window and keep valuables away from the windward window.

The typhoon may cause water and power outages, so we should make good daily life reserves in time. Check the wiring. If there is water in the room, you must cut off the power first. Prepare flashlights and candles, and reserve drinking water to prevent power failure and water supply; If there are only elderly people at home, or the vegetable market is far from home, it is necessary to prepare food and vegetables for a day or two.

Residents living in low-lying areas along rivers and beaches should guard against river flooding and seawater intrusion and move to higher-lying areas as soon as possible. Outside

Try not to go out when there is strong wind. If you have to go out, you must dress up eye-catching, bend down and walk slowly, try to grasp fixed objects such as railings, and bend down and walk slowly when crossing the bridge or walking at high places. Pay special attention to falling objects when walking in the street, and never go to dangerous old houses, sheds, temporary buildings, scaffolding, telephone poles, trees, billboards, iron towers and other places that are easy to cause casualties. At the same time, it should not be close to iron towers, transformers, metal sheds, etc. Don't stay under the big tree or near the railway. After the typhoon, don't approach the landing line when you see it. You can put up a warning sign first and then call the power hotline for warranty.

Riding a bicycle, moped or motorcycle is more impulsive than walking in the wind, and the front of the car is easy to get out of control. Therefore, it is best not to ride a bike during the direct impact of the typhoon. When driving out, you should also keep a low speed and see the road clearly.
