Social authorities have launched mass fire dispersed evacuation drill, build a fire safety "firewall" four ability to enhance fire safety, "" one of the important measures for construction. Safe and dispersed about the promotion of social units, such drills arrangements to assist the public to grasp the knowledge and skills of the fire escape must not do less. However, many social units now arranging an the fire dispersed escape drills are there a lot of errors, if doing preliminary tasks and knowledge explanation is insufficient, these problems are not treated significantly affect the fire escape drill results. A necessary explanation of knowledge of fire escape drill a through personal experience learned to escape technique drills, but the necessary arrangements before the drill with hair booklet, speak, explain the way the knowledge to the participants, or participants can not grasp the fire escape intact knowledge. The necessary commentary knowledge mainly the following aspects: 1. Fires dispersed differences fire escape fire dispersed social unit program, arrangements to guide about mass evacuation fire arrangements action. Arrangements for the purposes of fire decentralized social unit leadership to defend some of the members and their employees not only to have knowledge and to arrange programs and guide the fire dispersed parting, and to grasp the knowledge and skills of the fire escape. The fire escape is the shoppers, hotel guests and residents agility to escape safely in the event of a fire, personal action. 2. Beginning of the fire remedial fire escape dividing line flame leap up to the ceiling, since the beginning of the fire remedy with the dividing line of fire escape. Found a small fire can remedy of self-defense, and once the flames leap up to the ceiling, that means that since the beginning of the fire remedy defeat, then the remedy should immediately threw a fire extinguisher or fire blanket to escape. 3 fire smoke fire death of the main reasons, according to statistics, 80 per cent of the officers who died in the fire buildings fire smoke formed, carbon monoxide during most killed elements. The minimal inhalation in the fire escape fire smoke. Mimic fire smoke generating devices pick arrangements fire escape drill, we often use a variety of fuming device to imitate fire smoke, construction fire atmosphere, which is necessary. However, smoke devices if the election was not good, there will be a lot of side effect. For example, the use of sulfur and sawdust as the main raw material of smoke cake fuming happens sulfur dioxide and other gases, these gases briefly wet mucosal appearance absorption generates sulfurous acid, sulfuric acid, intense effect on the eyes and respiratory mucosa, many inhalation may cause lung edema, laryngeal edema, vocal cord spasms and eye irritation. Chosen the chemical incineration agents diesel, cotton yarn, wood chips for smoke agent or directly with phosphorus incineration sent the smoke device fuming solid particulate phosphorus pentoxide and other substances severe impact of the eyes, mucous membranes and respiratory system, the skin corrosive. Smoke hood after heating to the formation of environmental pollution, equipment corrosion, and affect our health. Ideal fuming equipment simply get a flat fire smoke release designed for fire escape developed into this category. Such equipment is non-toxic to the human body, environmental protection, and realistic to release a similar fire smoke. Third, the device should be equipped with the fire evacuation drill sites should advance to prepare the fire indicator mark, fire alarm the conditional units should also be prepared to imitate with Fire Escape Mask, fire shutter doors should also launch a fire prevention unit in fire escape drills shutter doors. Escape way in accordance with the height of the flue gas to the adoption of appropriate evacuation gesture the many fire science teachings, the base rule fire escape height of 1.4 meters. Bent over, the human body is lower than 1.4 m evacuated count correctly, or even if the fault is biased, this schematic method of discriminating. The correct approach is adopted based on the height of the fire smoke layer corresponding withdrawal posture. Fire smoke is lighter than air, it extends horizontally in the ceiling of the building first, and then gradually down dispersed, when the smoke layer away from the head, there is a larger interval bulging body can ran out; When the smoke layer dispersed to the head, people need to bent evacuation; When the flue gas is dispersed to the waist, a necessary crawling trek fled the scene of the fire. Approach is as little as possible inhalation of fumes quickly to escape. Fire mark indicates the direction to evacuate after the withdrawal, do not come back to fire five, out of misunderstanding in the area of ??the fire escape, and now there are some errors, these errors do not go out as the right approach to the purposes of the drill when will bring negative results. Wet towel to filter carbon monoxide Many fire popular science books are written in a wet towel can filter carbon monoxide, which is the biggest myths in the fire escape knowledge, the molecular weight of carbon monoxide 28, less than the molecular weight of oxygen and carbon dioxide, oxygen passes through the wet towel blanket inhaled, the carbon dioxide exhaled after a wet towel, smaller molecular weight of carbon monoxide can be filtered? significant lack of scientific knowledge. Wet towel that point the amount of water dissolved carbon monoxide can be ignored: carbon monoxide and carbon dioxide in the water solubility is not; Even the fire escape mask filter can not filter carbon monoxide, only between catalyst can carbon monoxide into carbon dioxide . 2 fire escape is necessary to escape and covered the mouth and nose with a wet towel and covered the nose and mouth with a wet towel, classic practices of our fire escape, some fire popular science books in the case of water, beer, beverage, and even urine wet towel, and covered the nose and mouth to escape this significant is misleading. There are these moments go wet towel, not as good as earlier to escape. Mass fire safety teachings discuss the most effective in the United States has never been blindfolded mouth and nose with a wet towel in the fire escape. The correct approach is just around the towel, wet it also does not take a few seconds, nothing wrong with it and covered the nose and mouth, such escape can cut the fire air inhaled, can hinder the use of unnecessary calls. Do not spend the time to look for a towel, not to spend more time to wet it, because its effect is limited. [Shenzhen, fire extinguishers, fire extinguisher maintenance, Shenzhen, fire equipment, fire signs, fire engineering in Shenzhen, Shenzhen transport equipment, fire safety, exit lights, Shenzhen hydrant http://www.szytxffm.net best fire extinguisher maintenance company - Shenzhen far through fire valve] quilts wet, cover the body aired images are able to find such a picture in many of our fire escape. The picture is created by the Japanese in the early 1950s, when the wood structure of the house in Japan accounted for a high share. Especially earthquake fire fire, wooden beams and rafters are able to fall. Later, the picture on the sow to China, has also become one of the many classics Fire preached painting. If we say that the Japanese initially to do so there is a reasonable side, China today also do so misleading. The primary now few wooden structure of the house. Second, take wet quilts have been able to quickly escape the moment. Third, cover a large quilt significantly affect the escape speed, locals in a hotel Phi quilts escape behind stepped on the front of the quilt, not only affect the escape velocity of the crowd, and will incur The escape scene disorders. Increasingly not imagine that we are under the stairs. Fourth, cover the quilt affect escape those who see the fire indicator mark. The correct approach is to quickly escape. Even the corridor temperature higher only need to be able to accept rushed past. If the home is equipped with a fire blanket draped over his body then be able to pull down.
