fire is indescribable disaster in itself - suffer buildings destroyed tangible assets (property, money, equipment), accumulated by families for decades.Uncontrolled fire is injurious to health and life of every living creature.But while there are fire hazards that are not so it is obvious for a person rarely encountered or do not face such a catastrophic trouble.
Clearly, the first of these factors is the fire and the concomitant temperature.That they cause damage to the main property, human health and property.But behind them are the other fire hazards, and in front of all - a lack of oxygen.Even students from the physics-chemistry course knows that the combustion is possible only in the presence of this gas.And with an open fire, especially if the area is large, oxygen is consumed with incredible speed.Because of what his lack of starts, causing oxygen starvation.At the initial stage it entails rapid heartbeat, decreased brain activity and poor coordination.At very low levels of oxygen, death occurs almost instantaneously.
Chemical factors
To fire hazards are also smoke, carbon dioxide and carbon monoxide gases.CO2 (carbon dioxide) does not smell and does not have color, but if the air it is more than 10%, people lose consciousness, and to get out of the house in flames can not.Carbon monoxide is an insidious and more dangerous - even a slight concentration in half an hour killing a man is not worse chemical warfare agents.Smoke is included in a sad list titled "Hazards of fire" because the very difficult orientation in a smoky environment.A man spends more time to get out into the street, and therefore much more likely to get burned, or poisoning listed combustion products.
Physical factors
fire hazards - this failure (collapse of buildings or some industrial designs).And here the risks are not just breaking, for example, concrete walls, and their fragments, which can fly at a very considerable distance.
secondary fire hazards
Besides the already mentioned fragments, it is worth remembering liquids that from the heat may spray.Moreover, their temperature can be above the boiling point of water.Then, perhaps spreading and spillage of toxic and even radioactive materials from damaged equipment.No less dangerous and torn wires, especially with high voltage (electric shock, a fire killed a lot of people).And, of course, here you can include panic and despair, because that got thrown into a fire trap to the upper floors of skyscrapers often for a minute until the rescuers.
Prediction danger
While smothering fire can bring great benefit to predict fire hazards.So, if any burning chemical plant, it is logical to assume that the air will contain a huge amount of toxic chemicals.Knowing what produces the factory, you can stock up in advance drugs to lower toxic effects.If lit parking lot or gas station, of course, that first of all you need to put out something that might explode.
