1. What should I do when I hear the fire when I'm asleep?
When you are asleep, when you hear the alarm signal, many people open the door with panic and try to rush out. This approach is very dangerous. The correct approach is:
(1) Climb to the door of the bedroom and try by hand to see if the door is hot.
(2) Prepare a wet towel.
(3) Do not arbitrarily jump from a building and try to land safely by using a life-saving rope.
(4) Use natural conditions as a lifeslide.
2. How to correctly determine the fire situation in the doorway
When the room in the doorway is already on fire, if you open the closed door rashly, you will often be subjected to fierce high-temperature and heavy smoke attacks. This will not only prevent you from escaping and you will not be able to close the door again, and even lead to a fire room.
When the hand feels that the facade has warmed up, it indicates that a serious fire has occurred outside the door. Hand touch the facade to determine whether the warming should be higher from the ground, the better, for the hollow metal door to feel the door surrounding temperature. It is also a very effective method to check whether there is flue gas flowing through the door. Most of the flue gas should flow from the upper part of the door, but when it is affected by the operation of the house ventilation system or when a fire-resistant hard door closure is installed It is not always reliable to rely on smoke to determine the fire situation. When the front door is exposed to the flame within 1min, the bottom of the metal doorknob feels warm, so touching the bottom of the handle with your hand is also a reliable way to feel a fire outside the door.
3. What happens when you get fire on your body?
After a person is caught in the fire, he cannot run. The more he runs, the more prosperous he is. This is because people will accelerate air convection and promote combustion as soon as they run, and the fire will become even fiercer. "Running" not only fails to extinguish the fire, but also brings the fire to other places. It may also increase the fire. This is very dangerous. The specific measures are as follows:
(1) Take off your clothes as much as possible, immerse yourself in water or use your feet to extinguish it.
(2) If it is too late to undress, you can also plunge on the floor and smash the flames on your body.
(3) You can jump into a pool or pond near a person. However, if the burn area is large, you cannot jump into the water to prevent infection.
(4) Never use a fire extinguisher to spray directly on the fire, as most fire extinguishers will cause infections from burn wounds.
4. How to Use a Wet Towel to Prevent Smoke
(1) The number of folded layers varies depending on the texture of the towel. Generally, it is preferable to fold the towel 8 layers so that the smoke concentration can be eliminated by 60%.
(2) Cover your mouth and nostrils when using, and increase the area of the filter.
5. How to call for help when a person is trapped indoors in the event of a fire
People were trapped inside the building by the fire and called for help. People outside could hardly hear it. It is actually very difficult to call for help because the raging fire forms a wall of fire. At this moment, those who are being arrested should remain calm and lie down on the ground to call for help. As the fire rises in accordance with the air flow, in the low-lying areas, the combustibles have burned or there are still unburned parts. The sound waves of the cries for help can be transmitted through these gaps, so that the outside world can easily hear the cry for help and can try to rescue them in time. .
6. What should you pay attention to when you are dying?
(1) It is necessary to hold some quilts, sofa cushions and other soft items, which can reduce the impact.
(2) Choose to go downstairs asbestos wagon sheds, flower gardens, pool waterfronts or lush tree hops, which can reduce casualties.
(3) Hold the head tight when jumping with bare hands, bend the body, and squash it. This will reduce the possibility of the head landing.
7. Which fire prevention problems should be noticed after power failure
(1) If conditions are available, emergency lighting should be used, as far as possible without lighting. If conditions are limited and you use an open flame with oil lamps, candles, etc., keep away from mosquito nets, curtains, books, newspapers and other combustibles.
(2) The use of oil lamps and candles for emergency lighting must be guarded. The person should extinguish the fire when leaving or sleeping.
(3) Do not hold candles and oil lamps to find things under the bed, inside the cabinet, and in narrow places so as to avoid accidentally burning combustibles and causing fire.
(4) Pull out the power plugs of electric irons, electric irons and electric blankets in a timely manner to prevent the electric power from being turned on for a long time after the call. The temperature rise will cause fire.
(5) Unplug the power plugs of televisions, radio receivers, and combo systems in a timely manner to prevent prolonged power-on after an incoming call. This will cause the insulation layer to break down and cause a short circuit to cause a fire.
8. How to do if the computer catches fire
If the computer catches fire, even if the camera is turned off or even the plug is unplugged, the components inside the camera may still be hot. It may still cause flames to enter and exit and produce toxic gas. The fluorescent screen and picture tube may also explode. The method to deal with is as follows:
(1) When the computer begins to smoke or catch fire, immediately unplug the power plug or turn off the main power switch, and then cover the computer with a wet blanket or quilt, which will not only prevent the spread of smoke, but also block the glass fragments of the screen.
(2) Do not splash water on the fire-fighting computer, even if the computer has been turned off, because the sudden drop in temperature will burst the hot cathode-ray tube. In addition, there is still residual current in the computer, splashing water may cause electric shock.
(3) When extinguishing a fire, do not lift the cover to watch. To prevent the explosion of the picture tube, one can only approach the computer from the side or behind.
