Previously, the main means of combating fire was the destruction of the buildings closest to the focus, sometimes the weather helped. There were no warning systems at all. The first fire alarm appeared more than a hundred years ago – in 1907. Now, during the construction of any building, a prerequisite is to equip the premises by means of fire protection. But how to figure out whether they are reliable and will they be able to save their lives during a fire?
A system that protects the house from a fire or at least warn in residents about it should be installed in each residential building, which can be divided into two conditional groups – low -rise and high -rise groups. Which system will be installed in the house depends on its height. The rule acts here: the higher the building, the more difficult it is to fight the fire and the more reliable it should be its protection. A device such as a smoke removal valve is indispensable when arranging heat and smoke systems.
After all, it is not a secret that when fire, the most dangerous is the smoke of the room. If the duct is equipped, then the smoke will go out and not accumulate in the apartment. This is due to the sensors that are installed along with the equipment. When it is triggered, the valves open and the smoke leaves the apartment. Today, all buildings with a height of more than 28 meters should be equipped with devices.
Since this is the maximum height from which you can evacuate people from the windows of burning apartments with the help of standard fire brigades. With a larger height, the main fire safety means are smoke removal systems. They allow the evacuation of people without fear of carbon monoxide poisoning and combustion products.
