international fire escape device
slide or slideway
Japan has developed a spiral outdoor staircase made of stainless steel, each floor has two turns, and it is designed with a safe descending slope, and the descent is very smooth. The United Kingdom has developed a nylon membrane inflatable bag which can be inflated within 5 minutes. After inflation, the nylon membrane bag is immediately formed into a groove-shaped inclined slide, so that people can quickly get out of danger in the soft slide.

the high-rise escape device
is installed at the junction of the wall surface and the ceiling of the window, which is in the shape of a roll and is usually covered by a curtain frame. The escape device is surrounded by tens of meters of steel wire rope, equipped with a belt and has a special damping structure. In case of sudden fire, residents can buckle their belts around their waist and jump out of the window. In a few tenths of a second, the damping structure in the escape device will produce great resistance, which will reduce the descending speed to 1-1.5 m/s and land safely.
pocket parachute
the United States has developed a pocket parachute strap with a pair of spring locks. When in use, the lock catch is fixed on the object, and the strap is put on to slide down.
safety landing net
The nylon net is 12 meters long. When there is a fire, people will tie one end of the safety net firmly, get into the net mouth and slowly fall to the ground along the net.
Life-saving air bag cushion
Life-saving air bag cushion, with dozens of square areas, is divided into two layers, and the upper pressure is low, so people will not bounce off when jumping on it, which can play a buffering role so as to land safely when jumping from the third and fourth floors.
high-rise escape shoes
In July 24, Jensen, a 67-year-old Danish, invented a high-rise "sliding shoes" safety system, which was installed in high-rise buildings in Denmark to help people escape in an emergency. It is said that the inventor was inspired by people jumping out of the windows of the World Trade Center when the "9.11" attack occurred in the United States. Shortly after the attack, Jensen applied for a patent for his "sliding shoe" safety system, which slides up and down by a narrow rail installed next to the window outside the building.
Four treasures of family fire prevention
There are four treasures of family fire prevention: household fire extinguishers, safety ropes, flashlights and gas masks. I believe that these things can be bought in omnipotent Taobao or other e-commerce.
Home fire extinguishers are very useful in the initial stage of a fire, which may nip a fire in the bud. Because we can know that some liquids are on fire, and water does not work. Needless to say, the flashlight is a must-have item for the family after the power failure. What needs attention is that you should be able to ensure that you can find it in a short time, otherwise you will be in a hurry in an emergency and your brain will be more stupid. Secondly, after the fire broke out, the wires were burned out, and the lighting was lost. In addition, the room was often dark under the cover of smoke. At this time, if a flashlight helps to illuminate, it is easy to find a way out. Third, the safety rope is easily overlooked. If you live on the fire floor and the fire is fierce, you can tie the rope to the balcony railing or window frame to escape. The safety rope should be long enough, and it would be better if there is a safety hook. Needless to say, gas masks, many people who died were mostly smoked to death. If there is no mask, the towel can also cope with the sudden situation. In fact, what I want to say most is that if you have the above devices, you'd better study these items with scientific exploration, so that you can improvise when you escape.
how to use portable dry powder fire extinguisher
1. Bring the fire extinguisher to the scene, quickly go to the fire point, and put it down at a position about 5 meters away from the fire source. Roll it up and down several times before using the fire extinguisher to prevent the dry powder from caking.
2 Then open the lead seal and unplug the safety pin. At this time, in order to ensure the availability of the fire extinguisher, the unopened fire extinguisher is in a protective state and cannot be used normally.
3 Hold the nozzle of the fire extinguisher with your left hand, press the handle with your right hand to ensure that the fire extinguisher is vertical, and aim at the bottom of the fire source to extinguish the fire at the upper air outlet.
4 in the process of fire extinguishing, gradually control the fire from near to far, and pay attention to continuous pressing with the right hand to ensure the normal injection of dry powder.
