How to escape in the smoke, the correct use of intelligent smoke detector

If the smoke detector has started to alarm to prove that the fire has occurred, we escape in the smoke, if the protection is not appropriate, it is easy to breathe the smoke into the human body, leading to fainting or suffocation, at the same time, the eyes will also be due to the irritation of smoke, resulting in stinging and unable to open.
We can use the transparent plastic bag, transparent plastic bag regardless of their size are available, the use of large plastic bags can be a whole live hood, and provide plenty of air for escape, if there is no big bags, plastic bags can also be small, although not completely covered his head, but also can cover your nose and mouth part, supply need the air to escape. When using plastic bags, be sure to fully open them, but do not blow them open with your mouth, because the gas blown in is carbon dioxide, the effect is counterproductive.
If you hear the alarm at night, you should first touch the door with the back of your hand and try if the door has become hot. If it is hot, the door cannot be opened, otherwise smoke and fire will rush into the bedroom. If the door is not hot, the fire may not be large, and escape from the room by normal means is possible. After you leave the room, be sure to close the door behind you to prevent the fire from spreading.
