With the development of social economy, there are more and more high-rise and super high-rise buildings in cities. Once a fire occurs, blind evacuation may lead to loss of life and property. In the event of a fire in a high-rise building, one should remain calm and pay attention to the following five aspects to ensure safe evacuation. 
Firstly, it is necessary to understand and familiarize oneself with the evacuation routes and safety exits of the residence in advance, so as to have a clear understanding and be prepared in case of emergencies. At least two staircases are available for evacuation in high-rise residential buildings. After a fire occurs, you can evacuate by looking for indicator lights or evacuation signs. Never take the elevator, it is a "fast lane" for thick smoke, and elevators are often prone to power outages, causing them to shut down. People in the elevator can be suffocated by thick smoke and toxic gases at any time. When choosing a hallway for escape and passing through areas with thick smoke, try to move forward quickly in the lowest or crawling position as much as possible, and cover your mouth and nose with a wet towel. Do not retreat to narrow corners, such as corners of walls, under tables, in wardrobes, etc. 
Secondly, when a fire is in the low fire stage, do not panic. You can use fire extinguishers or fire hydrants to extinguish it immediately. At this time, you should also call for people around you to come out and participate in extinguishing the fire and calling the police. If the fire cannot be controlled, you should evacuate immediately and close the door when leaving to prevent smoke from entering the hallway. After escaping from the fire, do not be greedy for wealth and return to dangerous places. When the ignition point is in another room or floor, you should touch the door handle with your hand before opening the door. If the temperature of the handle is already high or smoke is seeping in from the door crack, it means that the fire outside is already very strong. Do not open the door rashly. If the door lock temperature is normal or there is no smoke seeping in from the door crack, it means that the fire is still some distance away from you. At this time, you can open a door crack and observe the situation outside. When opening the door, one should press one foot against the door to prevent the heat wave outside from rushing the door open and causing the fire to spread. If you are confident that the fire does not pose a threat to yourself, evacuate the scene as soon as possible. 
Thirdly, when the passage has been sealed off by the fire and thick smoke, all doors and windows in the room should be closed to prevent air convection and delay the spread of flames. Some cloth strips can also be used to block the gaps between doors and windows. If conditions permit, water can be poured on doors and windows to reduce their temperature and wait for rescue. When living on a higher floor (over 3 meters), one should not blindly jump off the building. Instead, a signal for help should be sent out by throwing soft objects such as sofa cushions and pillows. At night, the flashlight can be turned on to let the people below know that someone is here, so that they can receive timely assistance. 
Fourthly, high-rise buildings usually have refuge floors. If it is not safe to escape to the ground, one should go to the refuge floor to escape and wait for rescue. 
The fifth is to help each other and escape together in the fire scene. For the elderly, weak, sick, disabled, pregnant women, children, and people who are unfamiliar with the environment, they should be guided to evacuate and assisted in escaping.
